Abstract Background Postoperative urinary retention (POUR) is a common complication characterized by fullness of the bladder without the ability to urinate. Its etiology in proctology surgery is multifactorial. This study aimed to identify the risk factors for POUR after radical surgery for anal fistula. Methods We retrospectively reviewed the clinical records of 511 patients who underwent radical surgery for anal fistula at the China-Japan Friendship Hospital from August 2022 to December 2023. Risk factors for POUR were analyzed by means of binary logistic regression analyses. Results POUR occurred in 57 patients (11.2%) within 48 h post-surgery, and males were predominantly affected (84.4%). Independent risk factors included a history of urological disease (OR = 6.048; p

Abstract Background Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR. Methods A nested case–control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609). Results The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence. Conclusion For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases.

Aims: The aim of this meta-analysis was to determine the pooled incidence of postoperative urinary retention (POUR) following total hip and knee arthroplasty (total joint replacement (TJR)) and to evaluate the risk factors and complications associated with POUR. Methods: Two authors conducted searches in PubMed, Embase, Web of Science, and Scopus on TJR and urinary retention. Eligible studies that reported the rate of POUR and associated risk factors for patients undergoing TJR were included in the analysis. Patient demographic details, medical comorbidities, and postoperative outcomes and complications were separately analyzed. The effect estimates for continuous and categorical data were reported as standardized mean differences (SMDs) and odds ratios (ORs) with 95% CIs, respectively. Results: A total of 31 studies were included in the systematic review. Of these, 29 studies entered our meta-analysis, which included 3,273 patients diagnosed with POUR and 11,583 patients without POUR following TJR. The pooled incidence of POUR was 28.06%. Demographic risk factors included male sex (OR 1.81, 95% CI 1.26 to 2.59), increasing age (SMD 0.16, 95% CI 0.04 to 0.27), and American Society of Anesthesiologists grade 3 to 4 (OR 1.39, 95% CI 1.10 to 1.77). Patients with a history of benign prostatic hyperplasia (OR 1.99, 95% CI 1.41 to 2.83) and retention (OR 3.10, 95% CI 1.58 to 6.06) were more likely to develop POUR. Surgery-related risk factors included spinal anaesthesia (OR 1.44, 95% CI 1.19 to 1.74) and postoperative epidural analgesia (OR 2.82, 95% CI 1.65 to 4.82). Total hip arthroplasty was associated with higher odds of POUR compared to total knee arthroplasty (OR 1.10, 95% CI 1.02 to 1.20). Postoperatively, POUR was associated with a longer length of stay (SMD 0.21, 95% CI 0.02 to 0.39). Conclusion: Our meta-analysis demonstrated key risk variables for POUR following TJR, which may assist in identifying at-risk patients and direct patient-centered pathways to minimize this postoperative complication.

Introduction and hypothesis: This study was aimed at determining the effect of sugammadex versus a combination of glycopyrrolate and neostigmine (GN) for neuromuscular reversal blockage on transient postoperative urinary retention (TPOUR) in patients undergoing a laparoscopic and robot-assisted laparoscopic hysterectomy. Methods: We conducted a retrospective cohort study in patients undergoing a laparoscopic or robotic hysterectomy between February 2017 and December 2021. Patients with and without concomitant procedures were included. Demographics and perioperative data were extracted from the patient's medical record. Before discharge, all patients were required to spontaneously void and have a post-void residual of less than 150 ml. Results: We identified 500 patients and 485 were included in the final analysis. We had 319 subjects who received sugammadex and 166 GN combination. Both groups had overall similar demographics and perioperative characteristics. Most patients had a conventional laparoscopy procedure (391 [82.5%]) compared with robotic (83 [17.5%]). Patients who received GN were significantly more likely to be discharged home with an indwelling catheter (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.09—3.05). After adjusting for perioperative medications and sling implantation during the surgery a logistic regression model continued to demonstrate that patients who received GN had significantly higher odds of being discharged with a catheter (OR, 1.79; 95% CI, 1.03–3.12). Conclusions: Our findings suggest that sugammadex decreases the odds of TPOUR after laparoscopic hysterectomies with and without slings compared with the combination of GN. Additional prospective trials are required to confirm this finding. [ABSTRACT FROM AUTHOR]

Introduction: Postoperative urinary retention (POUR) is a common complication after hip surgery. The enhanced recovery urinary protocol (ERUP) is a tool that employs several perioperative strategies to facilitate optimal conditions for surgery and recovery. The aim of this study was to evaluate the effect of ERUP on POUR in patients undergoing hip surgery. Methodology: A controlled pre- and post-quasi-experimental study was conducted. Data was collected between May 2018 and January 2019 at the orthopedic department of one of the largest teaching hospitals affiliated with Menoufia University in Egypt. A convenience sample of 100 Egyptian patients (of both genders) undergoing elective hip surgery was equally allocated into two groups. The control group (n = 50) was given traditional routine perioperative nursing care, while the intervention group (n = 50) was subjected to ERUP. Data was collected from socio-demographic, medical, and surgical data sheets, preoperative medication assessment sheets, postoperative data sheets, and fluid balance charts. Results: ERUP application significantly reduced the length of hospital stay and the incidence of POUR in the intervention group. Conclusions: Implementation of the ERUP is recommended for patients undergoing hip surgery, as it has a significantly positive effect on reducing the incidence of POUR. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study is to evaluate the postoperative urinary complications and the optimal timing of foley catheter removal in patients who underwent free flap reconstructive surgery for head and neck pathology. Methods: A retrospective case-control study of head and neck patients who underwent free flap reconstructive surgery at a single institution between January 2009 and December 2021 was conducted. Patient risk factors for postoperative urinary retention (POUR) were analyzed. Fisher Exact and Wilcoxon Rank Sum tests were used to evaluate rates of foley replacement, straight catheterization, and catheter-associated urinary tract infection (CAUTI) and associated risk factors. Results: Two hundred and eleven patients were included in this study. Older age, lower BMI, lower intraoperative fluid volumes, and need for straight catheterization were statistically significant for POUR requiring foley replacement. Shorter total (P =.04) and postoperative (P =.01) foley duration showed statistical significance for POUR requiring straight catheterization. About 60% of patients who had straight catheterization required a foley replacement (P <.001). Only one patient (0.5%) developed a urinary tract infection (UTI). Conclusion: Foley catheter duration impacts the risk of POUR requiring straight catheterization and subsequently, foley replacement. Optimal timing for foley catheter removal in the postoperative period remains to be elucidated. Removal of catheters between 21 and 48 hours after surgery may decrease the risk of POUR without increasing the rate of CAUTI in patients with head and neck pathology undergoing free flap reconstructive surgery.

Background: Transanal total mesorectal excision has emerged as a potential solution to certain limitations associated with laparoscopic total mesorectal excision in rectal cancer patients. Differences in surgical approaches have raised questions regarding their impact on the risk of postoperative urinary retention, with limited data available from large scale randomized clinical study. Objective: To report incidence of postoperative urinary retention and evaluate the associated risk factors for transanal total mesorectal excision. Design: In this randomized controlled trial (ClinicalTrials. gov NCT06147492), we retrieved 524 patients who received total mesorectal excision (TME) for stage I–III rectal cancer between June 2019 and April 2022, and the patients were randomly assigned in a 1:1 ratio to undergo either taTME or laTME. Patients: We enrolled 524 patients who underwent total mesorectal excision for stage I–III rectal cancer between June 2019 and April 2022. Main outcome measures: The incidence of postoperative urinary retention. Results: Among the 524 enrolled patients, 261 were randomized to the laTME group, while 263 were were randomized the taTME group. The median age was 58 years, and 340 participants (64.8 %) were male. Notably, 37 individuals (7.0 %) experienced postoperative urinary retention during the follow-up period, with no significant disparity was observed between the taTME and laTME groups (6.8 % and 7.2 %, respectively, P = 0.98). Risk factors associated with PUR in patients following taTME encompassed early removal of the urinary catheter (P = 0.006), net infusion rate >4.09 ml kg−1.h−1 (P = 0.006), and an age surpassing 65 years (P = 0.0321). Limitations: The generalizability of the findings outside specialist rectal cancer centers may be limited. Conclusions: Transanal total mesorectal excision was not found to heighten the risk of postoperative urinary retention. Nonetheless, it is advisable removing postoperative catheter beyond the initial day and exercising caution in the administration of intravenous fluids in clinical practice for taTME procedures.

Objectives: Postoperative urinary retention (POUR) is influenced by many factors, and its reported incidence rate varies widely. This study aimed to investigate the occurrence and risk factors for urinary retention following general anesthesia for endoscopic nasal surgery in male patients aged >60 years. Methods: A retrospective review of medical records between January 2015 and December 2019 identified 253 patients for inclusion in our study. Age, body mass index (BMI), a history of diabetes/hypertension, American Society of Anesthesiologists (ASA) classification, and urologic history were included as patient-related factors. Urologic history was subdivided into 3 groups according to history of benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and current medication. The following was analyzed as perioperative variables for POUR development: duration of anesthesia and surgery; amount of fluid administered; rate of fluid administration; intraoperative requirement for fentanyl, ephedrine, and dexamethasone; postoperative pain; and analgesic use. Preoperatively measured prostate size and uroflowmetry parameters of patients on medication for symptoms were compared according to the incidence of urinary retention. Results: Thirty-seven (15.7%) patients developed POUR. Age (71.4 vs 69.6 years), BMI (23.9 vs 24.9 kg/m2), a history of diabetes/hypertension, ASA classification, and perioperative variables were not significantly different between patients with and without POUR. Only urologic history was identified as a factor affecting the occurrence of POUR (P =.03). The incidence rate among patients without urologic issues was 5.9%, whereas that among patients with BPH/LUTS history was 19.8%. Among patients taking medication for symptoms, the maximal and average velocity of urine flow were significantly lower in patients with POUR. Conclusions: General anesthesia for endoscopic nasal surgery may be a potent trigger for urinary retention in male patients aged >60 years. The patient's urological history and urinary conditions appear to affect the occurrence of POUR. [ABSTRACT FROM AUTHOR]

Aims: The aim of this study is to examine the association between diabetes mellitus and postoperative urinary retention on cerebral angiography (including intravascular interventional therapy). Methods: We collected data on the demographic characteristics and comorbidities, imaging and routine laboratory data, surgical information, and medications of patients who underwent cerebral angiography. Multivariate logistic regression was used to explore the correlation between diabetes and the incidence of postoperative urinary retention. Results: A total of 932 patients were included, with a mean age of 59.7 years (74.1% men). Postoperative urinary retention occurred in 40.8% of the diabetes mellitus group and 30.3% of the group without diabetes. Compared with the group without diabetes, those with diabetes were more likely to experience postoperative urinary retention. Patients with higher glycosylated hemoglobin A1c levels had a higher risk of developing postoperative urinary retention. Conclusions: Diabetes was independently linked to postoperative urinary retention following cerebral angiography and patients with glycosylated hemoglobin A1c levels > 6% were more likely to experience postoperative urinary retention. Therefore, clinically regulating blood glucose levels may help to reduce the likelihood of postoperative urinary retention after cerebral angiography. [ABSTRACT FROM AUTHOR]

To assess the diagnostic accuracy of a retrograde voiding trial for the restoration of spontaneous voiding function after prolapse and urinary incontinence surgery and thereby determine whether the retrograde method can be a reliable alternative to the spontaneous voiding trial. A retrospective cohort study. A single tertiary hospital in South Korea. Women who underwent operations for prolapse, urinary incontinence, or both. Sequential voiding trials on postoperative day 1 or 2—retrograde voiding trial followed by spontaneous voiding trial. Of the 408 women analyzed, 278 (68.1%) passed the spontaneous voiding trial on the first day of assessment and none experienced urinary retention after a successful voiding trial. Receiver operating characteristic analyses of retrograde voiding trials evaluating voided volume (VV), postvoid residual (PVR), and voiding efficiency (VE) all demonstrated high diagnostic accuracy for restoration of spontaneous voiding function, whereas measuring PVR and VE had better discriminative ability than VV (area under the curve [95% confidence interval] = 0.93 [0.90–0.95] for PVR, 0.94 [0.91–0.96] for VE, and 0.88 [0.85–0.91] for VV; DeLong's test between PVR/VE and VV p <.01). The optimal cutoffs determined by the Youden index were 200 mL for VV (sensitivity 85.0%, specificity 78.0%), 100 mL for PVR (sensitivity 84.0%, specificity 87.0%), and 66.7% for VE (sensitivity 86.0%, specificity 88.0%). The retrograde voiding trial is an accurate predictor for restoration of spontaneous voiding function after prolapse and incontinence surgery and can be a useful alternative to the spontaneous voiding trial.

Introduction: Transcutaneous electrical acupoint stimulation (TEAS) has been proposed for postoperative urinary retention (POUR). This meta-analysis evaluated the effect of TEAS in preventing POUR. Methods: Databases were searched until February 6, 2023. Randomized controlled trials (RCTs) about TEAS for preventing POUR were included. The primary concern was the incidence of POUR, with post-void residual urine volume as a secondary outcome. Results: Fourteen studies with 2865 participants were identified. TEAS reduced the incidence of POUR (RR = 0.44, 95%CI = 0.33 to 0.58, P

This program evaluation aimed to determine if a new touch-free catheter met expectations to reduce urinary tract infections (UTIs) and traumatic catheterizations at a 319-bed hospital on the Florida Gulf Coast. The hospital revised their Bladder Care Bundle policy in September 2020. This document provided an algorithm to determine if intermittent urinary catheterization is warranted rather than an indwelling catheter to relieve urinary retention. Concurrently, this change included the introduction of a new product. This trademarked touch-free hydrophilic intermittent catheter is considerably different from the traditional straight intermittent catheter previously utilized by the hospital. The hospital also requested demographic information be collected identifying the patients who typically require straight catheterization. This evaluation was completed by doing a retrospective chart review to obtain data that compared urinary catheterization outcomes before and after the touch-free hydrophilic intermittent catheter implementation. The data revealed before the introduction of the touch-free hydrophilic catheter, there were two adverse events noted as traumatic insertions and no development of UTIs. In the data analyzed after the adoption of the touch-free hydrophilic catheter, no UTIs or traumatic insertions occurred. In conclusion, ongoing surveillance for the development of UTIs and traumatic insertions after using the touch-free hydrophilic catheter is recommended to assess its impact over a longer period with a larger number of patients. Additionally, it begins to identify the contribution of this type of touch-free catheter being used for acute urinary retention in hospitalized patients. [ABSTRACT FROM AUTHOR]

Introduction: Postoperative urinary retention (POUR) is a complication of surgery defined as the inability to empty a full bladder. POUR can prolong hospital length of stay and increase rates of urinary tract infection in the postoperative period. Risk factors for the development of POUR include male sex, older age, select medications, and certain comorbid conditions. Surgical factors may also increase the risk of POUR. POUR occurs in up to 50% of patients undergoing colorectal surgery. Materials and Methods: This retrospective, single-center cohort study evaluated the incidence of POUR in patients admitted for colorectal surgery and were enrolled in a Colorectal Enhanced Surgical Recovery (CERAS) protocol. Our primary objective was to determine the incidence of POUR in patients treated under the CERAS protocol. Secondary objectives included evaluating the incidence of POUR in patients receiving intrathecal anesthesia. Results: Two hundred and twenty-eight patients were included. Sixty-six patients (28.9%) developed POUR during their hospitalization. Patients who developed POUR were more likely to be male (61.6% vs. 44.4%, P = 0.029) and tended to be older (mean ± standard deviation age, 61.4 ± 17.7 years vs. 56.8 ± 16.4 years; P = 0.069) compared to the non-POUR group. Regional anesthesia did not affect the incidence of POUR. Conclusions: We identified a rate of POUR in our CERAS patients consistent with previous studies. The risk of POUR increased with increasing age, male sex, and history of benign prostatic hyperplasia and diabetes mellitus. We found no difference in POUR incidence with the type of regional anesthesia utilized. [ABSTRACT FROM AUTHOR]

Short-acting spinal anesthetics enable rapid recovery after hip and knee arthroplasty; however, concerns with transient neurological symptoms (TNS) cause some to avoid using lidocaine. Postoperative urinary retention (POUR) is also a concern with spinal anesthesia. We sought to study the comparative rates of TNS and POUR between lidocaine, mepivacaine, and bupivacaine in a high-volume hip and knee arthroplasty setting. Data for 1,217 primary THA, TKA, and unicompartmental knee arthroplasty cases were reviewed and grouped by spinal anesthetic agent (lidocaine, mepivacaine, or bupivacaine). Of the 1,217 cases, utilization was 523 lidocaine, 573 mepivacaine, and 121 bupivacaine. The incidence of TNS and POUR requiring catheterization was measured both by clinical evaluation as well as a questionnaire sent to patients 14 days postoperatively. The overall rate of TNS was 8%. With the numbers available, there was no difference in rates of TNS between groups (6.9% lidocaine, 9.2% mepivacaine, and 4.1% bupivacaine; P =.297). There was no difference in rates of TNS or POUR between THA and TKA/unicompartmental knee arthroplasty. Bupivacaine had a significantly higher rate of urinary retention (9.1%; P <.001) than mepivacaine (2.8%) or lidocaine (1.5%). This study showed no difference in the rate of TNS between the 3 common agents used in spinal anesthesia. Short-acting spinal anesthetics such as lidocaine and mepivacaine can lower the rate of POUR requiring catheterization, helping to enable rapid recovery after hip and knee arthroplasty.

Postoperative urinary retention is a common concern after total joint arthroplasty (TJA) and can cause discomfort, incontinence and, if left untreated, myogenic changes to the bladder. However, overdiagnosis of postoperative urinary retention by bladder scans may lead to unnecessary interventions and delayed discharges. The purpose of this study was to compare the safety of two bladder management protocols following TJA. From January 3, 2022 to April 29, 2022, 519 consecutive patients operated on by thirteen surgeons underwent routine postoperative bladder scanning (standard protocol). From February 28, 2022 to April 29, 2022, a new protocol was introduced by three surgeons in 209 consecutive patients using a specific algorithm (selective protocol) so that only symptomatic patients had bladder scans. The primary outcome of interest was catheterization rate. Chi-square and Students t -tests were used for analyses. There were 37.7% of patients in the selective group who received scans. Times to catheterization, readmissions, emergency department visits, and straight catheterization rates (15.0 versus 14.8% P =.999) were similar. More scans in the selective group resulted in intervention (39.2 versus 15.0%, P <.001). Prevoid volumes were higher in the selective protocol (608 versus 448 mL, P <.001). Postvoid volumes were similar (233 versus 223 mL, P =.497). There was one readmission for a urinary tract infection in the standard group and no urinary-related readmissions in the selective group. The selective protocol had a higher rate of same day discharge, fewer bladder scans, and did not lead to increased rates of urinary-related complications. These findings suggest that selective bladder scanning for symptomatic patients can be safely instituted for TJA patients. [ABSTRACT FROM AUTHOR]

Spinal anesthesia is a safe alternative to general anesthesia but remains underrepresented in the ambulatory setting. Most concerns relate to low flexibility of spinal anesthesia duration and the management of urinary retention in the outpatient setting. This review focuses on the characterization and safety of the local anesthetics that are available to adapt spinal anesthesia very flexibly to the needs of ambulatory surgery. Furthermore, recent studies on the management of postoperative urinary retention provide evidence for safe, but report wider discharge criteria and much lower hospital admission rates. With the local anesthetics that have current approval for usage in spinal anesthesia, most requirements for ambulatory surgeries can be met. The reported evidence on local anesthetics without approval supports clinically established off-label use and can improve the results even further. [ABSTRACT FROM AUTHOR]

Sugammadex is a direct reversal agent of aminosteroid muscle relaxants, particularly rocuronium, with promptly and completely reverse of deep neuromuscular block (NMB), which allows better surgical conditions. Sugammadex exhibits advantages over indirect reversal agent acetylcholinesterase inhibitor neostigmine with less adverse effects. In this retrospective review, we compared the incidence of postoperative vomiting (POV), postoperative urinary retention (POUR), and hemodynamic changes between sugammadex and neostigmine/glycopyrrolate in reversal of muscular blockade. Sugammadex showed superior in all three aspects. The heart rate was 7.253 lower (P

Background: Pelvic organ prolapse is a common condition of pelvic floor dysfunction in women, especially in adult vaginally parous and elderly women. Because of its anatomy, the anterior compartment has a significant effect on urinary symptoms. Anterior colporrhaphy and colpocleisis are major anterior compartment prolapse-related surgeries. As we know, postoperative urinary retention (POUR) is one of the most common complications following pelvic floor surgery. To prevent this complication, indwelling bladder catheterization is routinely applied. In contrast, to minimize risk of infection and the patient's discomfort, the catheter should be removed as soon as possible. However, there is a lack of clarity regarding the optimal timing for catheter removal. Therefore, the aim of this trial is to compare the rate of POUR after anterior prolapse surgery between early transurethral catheter removal (24 h postoperatively) and our standard practice (on postoperative day 3). Methods: We conducted a randomized controlled trial among patients undergoing anterior compartment prolapse surgery between 2020 and 2021 at a university hospital. Women were randomized into two groups. After removal, if the second void residual urine volume exceeded 150 mL, POUR was diagnosed, and intermittent catheterization was performed. The primary outcome was the POUR rate. The secondary outcomes included urinary tract infection, asymptomatic bacteriuria, time to ambulation, time to spontaneous voiding, length of hospitalization, and patient satisfaction. Analysis was performed according to the intention to treat principle. The calculated sample size was 68 patients (34 patients in each group) for a 95% confidence interval, 80% power, 5% probability of type I error, and 10% data loss. Discussion: This study demonstrated that early catheter removal was comparable in POUR rate to conventional treatment with shorter hospitalization among patients undergoing anterior compartment prolapse surgery. Additionally, we observed no re-hospitalization owing to POUR. Therefore, early transurethral catheter removal is preferable following anterior compartment prolapse-related surgery.

Objective: The meta-analysis aimed to integrate the evidence of randomized control trials to estimate the efficacy of prophylactic tamsulosin on postoperative urinary retention (POUR). Methods: The PubMed, Embase, Web of Science, and Cochrane Library databases were searched through 1 March 2022 using predetermined keywords. Randomized control trials reporting the preventive efficacy of prophylactic tamsulosin against POUR were identified according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline. Pooled risk ratios (RRs) were calculated using a random-effects model or a fixed-effects model based on the results of heterogeneity assessment. A meta-regression analysis was performed to explore the potential sources of heterogeneity. Results: There were 14 studies with 1102 patients in the Tamsulosin group and 1119 patients in the Control group. The risk of POUR was significantly lower in the Tamsulosin group (156/1102 [14.2%] vs. 238/1119 [21.3%]; RR = 0.65; 95% CI: 0.50-0.86; P = 0.002; Heterogeneity: I² = 51%; P = 0.01). Tamsulosin administration was associated with a higher risk of adverse events (65/ 614 [10.6%] vs. 39/626 [6.2%]; RR = 1.72; 95% CI: 1.19-2.48; P = 0.004; Heterogeneity: I² = 0%; P = 0.70). The meta-regression identified the mean age of patients as the only potential source of heterogeneity. Subgroup analysis showed that the younger patients (age <50 years) might benefit more from tamsulosin intake (RR = 0.36; 95% CI: 0.19-0.70; P = 0.003; Heterogeneity: I² = 49%; P = 0.14). Conclusions: The current meta-analysis suggested that prophylactic tamsulosin contributed to the prevention of POUR, and younger patients (< 50 years) might benefit more from this preventive regimen. Tamsulosin was also associated with a higher risk of adverse events. [ABSTRACT FROM AUTHOR]

Objective: The present systematic review and meta-analysis aimed to estimate the prophylactic effect of alpha blockers against postoperative urinary retention (POUR) in orthopaedic patients.Methods: PubMed, Embase, Web of Science and Cochrane Library databases were searched between 1 January 1990 and 1 March 2023. The studies reporting the preventive efficacy of alpha blockers on POUR after orthopaedic procedures were identified. The pooled rates of POUR in the Intervention group (patients receiving alpha blockers) and the Control group (patients not receiving alpha blockers) were estimated and compared. The risk ratios (RRs) were calculated using the random-effects model. Subgroup analysis was performed based on surgical type. Trial sequential analysis (TSA) was conducted to confirm the robustness of pooled results.Results: Seven studies containing 1,607 patients were identified. The rates of POUR were similar between the two groups (Intervention group: 126/748 [16.8%] VS. Control group: 168/859 [19.6%]; RR = 0.75; 95% confidence interval [CI] 0.51 to 1.09; p = 0.130; Heterogeneity: I2 = 67.1%; p = 0.006). No significant difference in the incidence of POUR was observed in either the Arthroplasty subgroup or Spine surgery subgroup. The result of TSA suggested that the total sample size of the existing evidence might be insufficient to draw conclusive results. Administrating alpha blockers was associated with a higher risk of complications (88/651 [13.5%] VS. 56/766 [7.3%]; RR = 1.73; 95% CI 1.27 to 2.37; p = 0.0005; Heterogeneity: I2 = 0%; p = 0.69).Conclusion: Prophylactic alpha blockers do not reduce the risk of POUR in orthopaedic procedures, and administrating these drugs was associated with a higher risk of complications.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=409388.

Objective: To determine the perioperative characteristics associated with an increased risk of postoperative urinary retention (POUR) following vaginal pelvic floor surgery. Design: A retrospective cohort study using multivariable prediction modelling. Setting: A tertiary referral urogynaecology unit. Population: Patients undergoing vaginal pelvic floor surgery from January 2015 to February 2020. Methods: Eighteen variables (24 parameters) were compared between those with and without POUR and then included as potential predictors in statistical models to predict POUR. The final model was chosen as the model with the largest concordance index (c‐index) from internal cross‐validation. This was then externally validated using a separate data set (n = 94) from another surgical centre. Main outcome measure: Diagnosis of POUR following surgery while the patient was in hospital. Results: Among the 700 women undergoing surgery, 301 (43%) experienced POUR. Preoperative variables with statistically significant univariate relationships with POUR included age, menopausal status, prolapse stage and uroflowmetry parameters. Significant perioperative factors included estimated blood loss, volume of intravenous fluid administered, operative time, length of stay and specific procedures, including vaginal hysterectomy with intraperitoneal vault suspension, anterior colporrhaphy, posterior colporrhaphy and colpocleisis. The lasso logistic regression model had the best combination of internally cross‐validated c‐index (0.73, 95% CI 0.71–0.74) and a calibration curve that showed good alignment between observed and predicted risks. Using this data, a POUR risk calculator was developed (https://pourrisk.shinyapps.io/POUR/). Conclusions: This POUR risk calculator will allow physicians to counsel patients preoperatively on their risk of developing POUR after vaginal pelvic surgery and help focus discussion around potential management options.

Introduction and aims: Postoperative urinary retention (POUR) is a complication that often leads to adverse outcomes and prolonged hospital stay if treatment is delayed. The aim of this project was to improve the competence of nurses in the provision of preoperative POUR education and ensure all patients received preoperative POUR education, and hence reduce the incidence of POUR. Methods: The evidence-based quality improvement project utilized JBI's Practical Application of Clinical Evidence System and Getting Research into Practice module, adopting two POUR best practice recommendations and two audit criteria. The first criterion was for nurses to conduct preoperative education on POUR and the second criterion was to initiate early ambulation of postoperative patients. The project was implemented in three phases from June 2019 to August 2020 in short-stayer and day surgery wards. Results: Criteria 1 and 2 revealed low compliance of 0 and 30%, respectively, during preimplementation audit. There were significant improvements in the first and second cycles of postimplementation audit for both criteria 1 and 2. Our results indicated that most of the patients who were ambulated early were able to void urine. However, there were a few incidents of urinary retention reported despite early ambulation. Following the audit of the third cycle of postimplementation, the compliance for both criteria were found to be satisfactory (criteria 1: 87%, criteria 2: 82%). Conclusion: The implementation of the evidence-based quality improvement project reduced the incidence of POUR. A standardized management would enable nurses to provide consistency in care and effective management and hence prevent the occurrence of POUR. [ABSTRACT FROM AUTHOR]

Sugammadex is a direct reversal agent of aminosteroid muscle relaxants, particularly rocuronium, with promptly and completely reverse of deep neuromuscular block (NMB), which allows better surgical conditions. Sugammadex exhibits advantages over indirect reversal agent acetylcholinesterase inhibitor neostigmine with less adverse effects. In this retrospective review, we compared the incidence of postoperative vomiting (POV), postoperative urinary retention (POUR), and hemodynamic changes between sugammadex and neostigmine/glycopyrrolate in reversal of muscular blockade. Sugammadex showed superior in all three aspects. The heart rate was 7.253 lower (P < 0.0001) and mean arterial pressure was 5.213 lower (P < 0.0001) in sugammadex group. The POV of neostigmine/glycopyrrolate group was 3.16 times more than sugammadex group (OR = 3.16, p < 0.0001), and POUR of neostigmine/glycopyrrolate group was 4.291 times more than sugammadex group (OR = 4.291, p < 0.0001). Sugammadex showed better hemodynamic stability, and lower incidence of POV and POUR than neostigmine/glycopyrrolate. [ABSTRACT FROM AUTHOR]

Background: Postoperative urinary retention (POUR) is a common and disruptive complication following total joint arthroplasty (TJA). The aim of this study is to investigate whether doxazosin can decrease the incidence of POUR and promote recovery under the setting of modern enhanced recovery after TJA.Methods: In this randomized placebo-controlled trial, patients over 35 years of age undergoing primary unilateral TJA were recruited. Patients received doxazosin (4 mg once) or placebo 2 h before surgery. The primary outcome of interest was the development of POUR, which was diagnosed when patients with a urine volume over 400 ml or overflow incontinence. Postoperative recovery was assessed in terms of hospital length of stay after surgery, daily ambulation distance, visual analogue scale (VAS) pain score and opioid consumption.Results: A total of 170 male patients were equally randomized into Doxazosin group (mean age 54.2 ± 13.7 years, range 36–88 years) and Placebo group (mean age 54.6 ± 13.9 years, range 38–81 years). The POUR rate was significant lower in Doxazosin group (17.6%) than in Placebo group (36.5%) (p = .006). The mean LOS in the Doxazosin group was 3.1 ± 1.1 days compared to 3.6 ± 1.7 days in the Placebo group (p = .030). Doxazosin group had a longer daily mobilization distance than Placebo group on postoperative day 1 (26.8 ± 11.1 vs. 22.8 ± 9.7; p = .015). Postoperative pain assessed by VAS score and opioid usage was comparable between two groups.Conclusion: Our results support the routine use of prophylactic doxazosin in male patients to decrease POUR rate and promote postoperative recovery under the setting of modern enhanced recovery after TJA.

Introduction and hypothesis: To identify the optimal cost-effectiveness threshold of post-void residual (PVR) by bladder scan in postoperative urogynecologic patients. Methods: A cost-effectiveness analysis was performed as a secondary analysis of a previously published study of patients undergoing urogynecologic procedures with planned voiding trials, setting thresholds for postoperative PVR bladder scan volumes at 100 ml, 150 ml, and 200 ml. Patient-based scenarios were modeled for ambulatory office or emergency department (ED) resource utilization and to determine the cost-effectiveness of each threshold. Costs were obtained from a southeastern academic medical center, only utilizing direct medical costs and hospital costs, not including societal costs. Quality-adjusted life years (QALY's) were used as health outcomes determining the incremental cost-effectiveness ratio (ICER). Results: A total of 151 patients from the original study were included. A willingness to pay threshold of $100,000 per QALY was assumed. A PVR of 100 ml exceeded this at $373,824. A PVR threshold of 150 ml was dominant (-$1,211,716), while minimizing ED visits for postoperative urinary retention (POUR) and unnecessary clinic appointments. While a PVR of 200 ml appeared a cost-effective strategy (-$488,389), there was increased ED utilization and under-detection of postoperative urinary retention (POUR). Conclusion: A PVR threshold of 100 ml created a healthcare system burden due to increased office voiding trials. Both PVR thresholds of 150 ml and 200 ml were cost-effective strategies; however, ED utilization for POUR increased with 200 ml. Utilizing 150 ml as the PVR cut-off proved the most cost-effective strategy, avoiding POUR under-detection and undue health costs. [ABSTRACT FROM AUTHOR]

Purpose of Review: In this review, current literature on bladder dysfunction following ureteral reimplantation of any kind was reviewed. Topics include the neuroanatomy of the vesicoureteral junction and nerve-sparing ureteral reimplantation, postoperative urinary retention, treatment of urinary retention, risk factors for urinary retention, and other forms of bladder dysfunction following ureteral reimplantation. Recent Findings: Following attempts at nerve-sparing extravesical ureteral reimplantation, the incidence of postoperative urinary retention has ranged from 0 to 15% for combined unilateral and bilateral reimplantation and 0% to 37.5% for bilateral extravesical reimplants. Summary: Postoperative bladder dysfunction has been most commonly observed following bilateral extravesical ureteral reimplantation but can occur following any ureteral reimplantation. Urinary retention is the most well characterized complication but occurs at highly variable rates. History of bowel bladder dysfunction, bilateral ureteral reimplantation, and prolonged operative time are risk factors for postoperative urinary retention. While rare, urinary retention is most commonly transient and resolves by 6 weeks postoperatively but can persist beyond two months postoperatively. There are rare reports in the literature of significantly prolonged urinary retention following ureteral reimplantation requiring lower urinary tract reconstruction to address the urinary retention.

Epidural analgesia is effective and an accepted treatment for postoperative pain. Urinary retention is a known complication, but its description is mostly in the adult literature. Management of urinary catheter (UC) placement and removal is an important consideration in children receiving epidural analgesia. This is a single-center, retrospective observational study which examined UC management in children undergoing lower extremity orthopedic surgery under general anesthesia with or without epidural analgesia from January 2019–June 2021. Of 239 children included, epidural analgesia was used in 57 (23.8%). They were significantly younger and had more co-morbidities. In total, 75 UCs were placed in the OR, 9 in the ward, and 7 re-inserted. UC placement in the epidural group was more common (93% vs. 17%, p < 0.001) and remained longer (3 days vs. 1 day, p = 0.01). Among children without intra-operative UC, ward placement was more common in the epidural cohort (60% vs. 1.6%, p = 0.007). OR UC placement and ward re-insertion were more common in children with neuromuscular disease (61% vs. 22%, p < 0.001), (17% vs. 3%, p = 0.001), respectively. Based on these findings, we hypothesize that it is justifiable to routinely place a UC intra-operatively in children who undergo hip or lower extremity surgery and are treated with epidural analgesia, and caution is advised before early UC removal in orthopedic children with NMD.

ObjectiveThe meta-analysis aimed to estimate the efficacy of prophylactic tamsulosin on postoperative urinary retention (POUR) in male patients.MethodsPapers were searched in the PubMed, Embase, Web of Science, and Cochrane Library databases with predetermined keywords up to March 1, 2022. The studies reporting the preventive efficacy of prophylactic tamsulosin on POUR among men were identified. Pooled risk ratios (RRs) were calculated based on the random-effects model. Meta-regression was performed to explore potential sources of heterogeneity.ResultsThere were 11 studies with 1,046 patients in the tamsulosin group and 1,113 patients in the control group. The risk of POUR was significantly lower in the tamsulosin group (123/1,046 [11.8%] vs. 238/1,119 [19.0%]; RR = 0.61; 95% confidence interval [CI] 0.43 to 0.87; P = 0.006; heterogeneity: I2 = 57%; P = 0.009). Administration of tamsulosin was related to higher risk of adverse events (57/688 [8.3%] vs. 33/624 [5.3%]; RR = 1.68; 95% CI: 1.13 to 2.48; P = 0.010; heterogeneity: I2 = 33%; P = 0.20). The level of evidence and mean age of the included patients were identified as the potential sources of heterogeneity.ConclusionThe present meta-analysis indicated that prophylactic tamsulosin helps in preventing POUR and younger patients might benefit more from this preventive regimen. Administrating tamsulosin was also associated with a possibly higher risk of adverse events.

Objective: This research was conducted to characterize the prevalence and outcomes of postoperative urinary retention (POUR) after laparoscopic hysterectomy (LH) for definitive surgical management of stages III and IV endometriosis without an explicit nerve-sparing (NS) technique. Materials and Methods: This was a retrospective chart review of 106 cases from a single institution of patients who underwent LH for severe endometriosis without an explicit NS technique between March 2014 and August 2020. Six cases were excluded for concurrent low anterior–bowel resection, laparotomy, or incomplete charting. Results: The primary outcome was persistent POUR, defined in this study as continued need for catherization and self-reported sensation of POUR at ∼6 weeks postoperatively. At this time, 5/100 (5.0%) patients met the criteria for persistent POUR, of which 1/100 (1.0%) had objective evidence of retention requiring further management. Immediate POUR was present in 19/100 (19%) of patients. Only 5/100 (5.0%) required continued catheterization past discharge. No patients required catherization at 6 weeks. Conclusions: In nonexplicit NS LH for severe endometriosis, POUR is transient and rarely requires post-discharge catheterization. This study highlights a need for more investigation comparing conventional and NS techniques for reducing POUR after definitive laparoscopic surgery for advanced-stage endometriosis.

Objectives The study was aimed to investigate the safety and feasibility of avoiding urinary catheterization after surgery in patients undergoing lung cancer resection. Methods Between 1 January 2014 and 31 December 2017, the patients with primary lung cancer who received lobectomy or segmental resection via video-assisted thoracic surgery (VATS) in our department were screened. Based on whether a urinary catheter was inserted after surgery, patients were divided into urinary catheter (UC) group or non-UC group, and rates of postoperative urinary retention (POUR), urinary catheter re-insertion and urinary tract infection (UTI) were compared. Results There was no difference in International prostate symptom score (p = .268) between the groups, but a higher Sedation-Agitation Scale (SAS) score was found in UC group [4.0 (3.0 4.0) vs. 4.0 (2.0, 4.0); p 4; 17.3%, 317/1,835 vs. 12.9%, 86/660, p = .008). In contrast, a higher rate of POUR was observed in non-UC group (11.2%, 74/660 vs. 7.4%, 136/1,835, p = .003), whereas the rate of UTI was significantly lower in this group (5.8%, 38/660 vs. 8.3%, 153/1,835, p = .033). Multivariable analysis revealed the non-placement of UC as the independent factor for POUR (OR: 1.542, 95%CI: 1.135-2.095, p = .006) and UTI (OR: 0.664, 95%CI: 0.459–0.962, p = .031). Conclusion This retrospective study with large sample of 2,495 patients provided evidence to the hypothesis that avoiding urinary catheterization contributed to decrease in the incidence of UTI and was safe and feasible in patients undergoing lung cancer surgery.

BackgroundsPostoperative urinary retention (POUR) is one of the most common complications after hemorrhoidectomy. The best treatment for POUR is prevention and should be involved in the whole perioperative period. Moxibustion has been used to treat urinary retention for thousands of years, and clinical studies have also proved its effects. We try to carry out a randomized, controlled, prospective study to observe whether prophylactic moxibustion could effectively reduce the incidence of POUR of hemorrhoidectomy in 24 h.MethodsThis study is a single-center, evaluator-blinded, randomized, and controlled trial. Participants who meet the inclusion and exclusion criteria in this RCT will be randomly assigned to either the treatment group (moxibustion) or the control group (tamsulosin hydrochloride) in a 1:1 ratio according to a computer-generated randomization list. Both moxibustion and tamsulosin will be used 1, 10, and 24 h after operation, respectively. The outcomes of occurrence of POUR, time to first urination, catheterization rate, urinary tract infection, length of hospitalization, and adverse effects will be recorded.DiscussionThe findings of the study will help to explore the preventive efficacy of prophylactic moxibustion against POUR of hemorrhoidectomy in 24 h.Trial RegistrationCHiCTR, CHiCTR2000039350, registered 24 October, 2020, http://www.chictr.org.cn/showproj.aspx?proj = 63204.

Abstract Purpose Transient postoperative urinary retention (POUR) is common after pelvic floor surgery. We aimed to determine the association between peri-operative variables and POUR and to determine the number of voids required for post-void residuals (PVRs) to normalize postoperatively. Methods We conducted a retrospective cohort study of 992 patients undergoing pelvic floor surgery at a tertiary referral centre from January 2015 to October 2017. Variables assessed included: age, BMI, ASA score, anaesthesia type, type of surgery, length of postoperative stay, surgeon, bladder protocol used, and number of PVRs required to “pass” the protocol. Results Significant risk factors for POUR included: placement of MUS during POP surgery, anterior repair and hysterectomy with concomitant sacrospinous vault suspension. A total of 25.1% were discharged requiring catheterization. Patients receiving a concomitant mid-urethral sling (MUS) were 2.2 (95% CI1.6–2.9) and 2.3 (95% CI 1.8–3.1) times more likely to have elevated PVR after their second TOV and third TOV (p 2 and placement of MUS were associated with increasing number of voids needed to pass protocol. Conclusions While many women passed protocol by the second void, using the 3rd void as a cut point to determine success would result in fewer women requiring catheterization after discharge. Prior to pelvic floor surgery, women should be counselled regarding POUR probability to allow for management of postoperative expectations.

Background: Postoperative urinary retention (POUR) is a known complication in the postanesthesia care unit (PACU). The variations in catheterization thresholds contribute to unnecessary invasive procedures. Objective: In the current study, we implemented an algorithm for a sterile intermittent catheterization (SIC) threshold of 800 ml with volume-dependent bladder scan intervals and compared the incidence of SIC with that of a matched patient cohort threshold of 400 ml. Design, setting, and participants: This comparative study of two prospective historical cohorts represented two thresholds for POUR, set at 400 ml without a standardized bladder scan protocol and 800 ml with a volume-dependent bladder scan protocol. Outcome measurements and statistical analysis: The primary outcome was the frequency of catheterization during the PACU stay. Secondary outcomes evaluated patient safety aspects in occurrence of thresholds above 400/800 ml. The study was set at the PACU under the Department of Anesthesia, Center for Cancer and Organ Diseases, Rigshospitalet, Denmark. Results and limitations: In total, 741 patients were consecutively included, with 307 in the POUR-400 and 434 in the POUR-800 group, and with comparable group characteristics. Significantly fewer patients fulfilled the SIC/catheter a’ demeure (CAD) criteria in the POUR-800 (5.0%) versus POUR-400 (14.3%) group, equivalent to a 65.0% relative reduction in SIC. Conclusions: Implementation of a standardized ultrasound-guided protocol with volume-dependent scan intervals and an evidence-based catheterization threshold of 800 ml decreases the need for SIC by >65%, without increasing the need for urinary catheterization at the wards. Patient summary: In this study, we implemented an algorithm for a sterile intermittent catheterization threshold of 800 ml with volume-dependent bladder scan intervals. A marked reduction was seen in catheterization in the postanesthesia care unit, without increasing catheterization rates at the ward.

Introduction and hypothesis: Previous studies have found that administration of phenazopyridine decreased short-term urinary retention following surgery but other more recent trials have shown mixed results. This study sought to investigate the potential benefit of preoperative administration of oral phenazopyridine in relation to the prevention of short-term urinary retention following urogynecologic surgery. Methods: This is a retrospective cohort study of a convenience sample of women undergoing urogynecologic surgery from June 2016 to March 2019. Following surgery, subjects underwent a standardized retrograde voiding trial. The data had previously been gathered from a prior prospective trial at our institution (Kesty et al. Int Urogynecol J 31(9):1899–1905, 11). Chart review was performed to determine whether patients that received 200 mg of preoperative oral phenazopyridine to better visualize ureteral efflux during cystourethroscopy were more or less likely to pass their postoperative voiding trial. Bivariate statistical analysis was performed as well as a multivariate logistic regression model. Results: A total of 165 subjects were included in the final analysis; 100 who did not receive preoperative phenazopyridine and 65 who did receive phenazopyridine. There was no statistical difference between voiding trial pass rates following urogynecologic surgery between those who did not receive preoperative phenazopyridine compared to those who did [77% (77/100) and 82% (53/65), respectively, p = 0.37)]. The multivariate logistic regression model demonstrated no difference in postoperative voiding trial pass rates among those who received preoperative phenazopyridine compared to those who did not (OR 1.7, 95% CI: 0.53, 5.8). Conclusions: Preoperative administration of oral phenazopyridine does not decrease short-term urinary retention following urogynecologic surgery. [ABSTRACT FROM AUTHOR]

Background: Postoperative urinary retention (POUR) in total joint arthroplasty (TJA) is common. However, risk factors for POUR and its consequences, specifically on postoperative renal function, have not been well defined. Methods: We performed a review of prospectively collected data on consecutive adult patients undergoing primary total joint arthroplasty from August 2014 to December 2015. Catheters were placed preoperatively and removed on the first or second postoperative day. The exclusion criterion was traumatic catheter insertion or the presence of fracture or neoplasm. Univariate and multiple logistic regression identified associations with POUR and its invasive therapies. Subgroup analysis of renal function by incidence of preoperative bladder outlet obstruction (BOO) and POUR was performed with nonparametric testing. Results: A total of 591 operations met inclusion criteria. The incidence of POUR was 6.4% and was directly related to a positive history of BOO (odds ratio [OR]: 4.15) and increased the duration of urinary catheterization (OR: 1.04). These factors, in addition to preoperative incontinence (OR: 8.36, 28.69) and lengthier hospitalizations (OR: 1.37, 1.30), were significantly associated with intermittent straight catheterization and reinsertion of an indwelling catheter to treat POUR. Serum creatinine increased with combined preoperative BOO and POUR (+0.22 mg/dL) but was preserved in others (+0.02-0.04 mg/dL) (P < 0.01). Conclusions: Preoperative BOO and longer catheterization increased the risk of POUR and were associated with the use of invasive modalities to treat POUR. POUR was associated with a longer hospitalization and impaired renal function in those with preoperative BOO; therefore, renal function should be monitored closely and nephrotoxic medications used cautiously when using urinary catheters in this patient population. Level of Evidence: Retrospective Analysis, Level IV.

To explore the core acupoints and combination rules of acupuncture therapy for postoperative urinary retention after hemorrhoidectomy, and, further to analyze the characteristics of the prescription of acupuncture therapy for postoperative urinary retention after hemorrhoidectomy. Relevant clinical studies in seven databases were searched systematically from database inception to 1st October 2020. Based on data mining techniques, the core acupoints, characteristics and combination rules of acupuncture therapy for postoperative urinary retention after hemorrhoidectomy were analyzed comprehensively. Statistics collected and analysis of acupoint selection included the frequency of usage of acupoints, the meridian of acupoints, the location of acupoints and the combination of acupoints. Cluster and association analysis were performed utilizing Excel 13.0 and SPSS 26.0. In the 36 studies included, the most frequently adopted acupoint was Sānyīnjiāo (三阴交 SP6); the most frequently adopted meridian was the foot-taiyin spleen meridian; the most frequently involved location was the lower limbs; and the most frequently adopted combination of acupoints was SP6 and Zhōngjí (中极CV 3). Cluster analysis showed that the acupoints could be divided into three categories: the first group comprised SP6 alone; the second group included CV3, Guānyuán (关元CV4), Yīnlíngquán (阴陵泉SP9) and Zúsānlǐ (足三里ST36); and the third group included Pángguāngshū (膀胱俞BL28), Chéngshān (承山BL57), Tàichōng (太冲LR3), Zhìbiān (秩边 BL54), Tàixī (太溪KI6), Hégǔ (合谷 LI4), Xuèhǎi (血海SP10), Qìhǎi (气海CV6) and Shǔidào (水道ST28). It was found that acupuncture therapy for postoperative urinary retention after hemorrhoidectomy mainly follows the four characteristic rules: the selection of acupoints following the meridian, selection of acupoints at local points, selection of acupoints at distal points and selection of acupoints according to special symptoms.

Purpose: To determine predictors for postoperative urinary retention in adolescents undergoing posterior spinal fusion for idiopathic scoliosis. Postoperative urinary retention affects almost every third adolescent after spinal fusion for idiopathic scoliosis. There are limited data regarding the risk factors of postoperative urinary retention in this patient group. Methods: A retrospective study with prospectively collected urinary retention data from paediatric spine register with 159 consecutive patients (114 females, mean age 15.6 years, range 10–21 years) undergoing pedicle screw instrumentation for adolescent idiopathic scoliosis at a university hospital between May 2010 and April 2020. Postoperative urinary retention was defined as an inability to void after catheter removal and documented residual over 300 mL as confirmed using an ultrasound or by catheterization. Results: Postoperative urinary retention was diagnosed in 33% (53 of 159) of the patients during hospital stay. Opioid amount on the day of catheter removal (OR 6.74 [95% CI: 2.47, 18.36], p < 0.001), male gender (OR 2.26 [95% CI: 1.01, 5.05], p = 0.048), and increasing weight (OR 1.04 [95% CI: 1.01, 1.07], p = 0.014) were associated with postoperative urinary retention. Mean opioid consumption on the day of catheter removal was 0.81 mg/kg (95% CI: 0.66, 0.96) in the retention group vs 0.57 mg/kg (95% CI: 0.51, 0.64) in the non-retention group, p < 0.001. Conclusions: Higher total opioid consumption, opioid amount on the day of catheter removal, higher weight, and male gender increases the risk of postoperative urinary retention in adolescents with idiopathic scoliosis undergoing posterior spinal fusion.

Objective:Urinary retention is a common postoperative problem. We aimed to investigate the incidence of postoperative urinary retention (POUR) in surgical population and identify the perioperative risk factors for POUR.Materials and Methods:A total of 332 patients, who underwent elective surgery between May 2012 and July 2012, were included in this prospective observational study. Patients under 18 years of age and those with a history of renal failure or benign prostate obstruction were excluded from the study. Group 1 was consisted of patients who had not developed POUR, whereas patients who experienced POUR were included in group 2. Demographic variables and risk factors related with POUR were compared between the two groups.Results:Of the 332 patients enrolled in the study, 179 (53.9%) were men and 153 (46.1%) were women. Thirty-three (9.9%) patients developed urinary retention. Comparison of demographic and perioperative variables between the two groups revealed that Diabetes Mellitus (DM) and spinal anesthesia were significantly associated with POUR (p=0.039 and p=0.043, respectively). Multivariate logistic regression analysis found that DM [p=0.017, odds ratio (OR): 3.009; 95% confidence interval (CI), 1.221– 7.414] and spinal anesthesia (p=0.031, OR: 2.266; 95% CI, 1.079-4.760) were significant independent risk factors for developing POUR.Conclusion:DM and spinal anesthesia were found to be risk factors for POUR. Awareness of risk factor for POUR during preoperative anesthesiology evaluation may help identify patients at risk for POUR, who could benefit from interventions, and prevent POUR and its potential complications.

Background and Aims: Following spinal anesthesia (SA), patient discharge is often delayed due to postoperative urinary retention (POUR), the incidence of which varies widely. The present study of bupivacaine versus ropivacaine in equianalgesic doses was taken to explore the correlation between time to void urine and time for complete functional recovery. Material and Methods: In this double-blinded study fifty adult patients were assigned to two groups (bupivacaine/ropivacaine) according to alternate case allocation for receiving SA for lower abdominal, perineal, and lower limb surgeries, lasting less than 2 h. Statistical analysis was conducted using an intention-to-treat approach, using Mann–Whitney test for nonparametric data. Primary outcome data could not be obtained for 14 out of the 50 patients due to perioperative bladder catheterization. No patients were lost to follow-up. Results: Both the bupivacaine and ropivacaine groups were comparable in terms of ability to void (8.0 ± 2.3 vs. 7.0 ± 1.2 h;P > 0.05), modified Bromage scale after 4 h of SA (1.8 ± 1.3 vs. 2.6 ± 0.9 grade;P > 0.05), time to complete ambulation (6.7 ± 1.4 vs. 6.1 ± 1.0 h;P > 0.05), and time to negative Romberg test (6.1 ± 1.4 vs. 5.6 ± 0.9 h;P > 0.05), respectively. Strong positive correlations (r = 0.7–0.9) were found between time to void urine and time for complete ambulation. Conclusions: Time to void urine and recovery of motor functions were found comparable statistically when bupivacaine and ropivacaine were used in the doses of 12.5 and 18.75 mg, respectively, for SA. However, group ropivacaine required lesser time to void and no patient developed POUR. Time to void urine was more than the time for ambulation. This may indicate a need for “selective spinal anesthesia” or adjuvant combination technique to accelerate the resolution of a block for ambulatory surgery.

Background: Postoperative urinary retention (POUR) is a common and distressing surgical complication that may be associated with the pharmacological reversal technique of neuromuscular blockade (NMB). Objective: This study aimed to investigate the impact that POUR has on medical charges. Methods: This was a retrospective observational study of adult patients undergoing select surgeries who were administered neuromuscular blockade agent (NMBA), which was pharmacologically reversed between February 2017 and November 2021 using data from the PINC-AI™ Healthcare Database. Patients were divided into 2 groups: those experiencing POUR (composite of retention of urine, insertion of temporary indwelling bladder catheter, insertion of non-indwelling bladder catheter) during index hospitalization following surgery and those without POUR. Surgeries in inpatient and outpatient settings were analyzed separately. A cross-sectional comparison was performed to report total hospital charges for the 2 groups. Furthermore, patients experiencing subsequent POUR events within three days after discharge from index hospitalization were studied. Results: A total of 330 838 inpatients and 437 063 outpatients were included. POUR developed in 13 020 inpatients and 2756 outpatients. Unadjusted results showed that POUR was associated with greater charges in both inpatient ( 92   529 w i t h P O U R v s 78 556 without POUR, p  < .001) and outpatient ( 48   996 w i t h P O U R v s 35 433 without POUR, p  < .001) settings. After adjusting for confounders, POUR was found to be associated with greater charges with an overall mean adjusted difference of 10   668 ( 95 95 760- 11   760 , p   <   .001 ) i n i n p a t i e n t a n d 13 160 (95% CI 11   750 - 14  571, p  < .001) in outpatient settings. Charges associated with subsequent POUR events following discharge ranged from 9418 i n p a t i e n t c h a r g e s t o 1694 outpatient charges. Conclusions: Surgical patients who were pharmacologically reversed for NMB and developed a POUR event incurred greater charges than patients without POUR. These findings support the use of NMB reversal agents associated with a lower incidence of POUR., Competing Interests: W.W., A.M.A., V.T., R.M., J.A., A.O.R., N.W.B., and Y.J. are employees of Merck Sharpe & Dohme LLC, a subsidiary of Merck & Co., Inc. Rahway, New Jersey, USA (MSD), and may own stock and/or stock options in MSD.

Background: Transanal total mesorectal excision has emerged as a potential solution to certain limitations associated with laparoscopic total mesorectal excision in rectal cancer patients. Differences in surgical approaches have raised questions regarding their impact on the risk of postoperative urinary retention, with limited data available from large scale randomized clinical study., Objective: To report incidence of postoperative urinary retention and evaluate the associated risk factors for transanal total mesorectal excision., Design: In this randomized controlled trial (ClinicalTrials. gov NCT06147492), we retrieved 524 patients who received total mesorectal excision (TME) for stage I-III rectal cancer between June 2019 and April 2022, and the patients were randomly assigned in a 1:1 ratio to undergo either taTME or laTME., Patients: We enrolled 524 patients who underwent total mesorectal excision for stage I-III rectal cancer between June 2019 and April 2022., Main Outcome Measures: The incidence of postoperative urinary retention., Results: Among the 524 enrolled patients, 261 were randomized to the laTME group, while 263 were were randomized the taTME group. The median age was 58 years, and 340 participants (64.8 %) were male. Notably, 37 individuals (7.0 %) experienced postoperative urinary retention during the follow-up period, with no significant disparity was observed between the taTME and laTME groups (6.8 % and 7.2 %, respectively, P  = 0.98). Risk factors associated with PUR in patients following taTME encompassed early removal of the urinary catheter ( P  = 0.006), net infusion rate >4.09 ml kg -1 .h -1 ( P  = 0.006), and an age surpassing 65 years ( P  = 0.0321)., Limitations: The generalizability of the findings outside specialist rectal cancer centers may be limited ., Conclusions: Transanal total mesorectal excision was not found to heighten the risk of postoperative urinary retention. Nonetheless, it is advisable removing postoperative catheter beyond the initial day and exercising caution in the administration of intravenous fluids in clinical practice for taTME procedures., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Background Context: Limited studies have investigated risk factors for postoperative urinary retention (POUR) following elective spine surgery. Furthermore, some discrepancies have been found in the results of existing observational studies.Purpose: This study aimed to review the available literature on risk factors associated with POUR following elective spine surgery.Study Design: A systematic review with meta-analysis was performed.Patient Sample: A total of 31,251 patients (POUR=2,858, no POUR=28,393) were included in the meta-analysis.Outcome Measures: Demographics, type of elective spine surgery, country, definition of POUR, and potential risk factors for POUR were evaluated.Methods: The Cochrane Library, Embase, and Medline electronic databases were searched to identify relevant studies. Binary outcomes were reported as odds ratio (OR). Weighted mean differences (WMD) or standardized mean differences (SMD), with 95% confidence intervals (CI), were used for meta-analysis of continuous outcomes.Results: Eleven studies (2 prospective and 9 retrospective) were included in the analysis. Patients with POUR were older than those without POUR (WMD, 7.13; 95% CI, 4.50-9.76). Male patients were found to have an increased risk of POUR (OR, 1.31; 95% CI, 1.04-1.64). The following variables were also identified as significant risk factors for POUR: benign prostatic hyperplasia (BPH; OR, 3.79; 95% CI, 1.89-7.62), diabetes mellitus (DM; OR, 1.50; 95% CI, 1.17-1.93), and previous urinary tract infection (UTI; OR, 1.70; 95% CI, 1.28-2.24). Moreover, longer operative time (WMD, 19.88; 95% CI, 5.01-34.75) and increased intraoperative fluid support (SMD, 0.37; 95% CI, 0.23-0.52) were observed in patients with POUR. In contrast, spine surgical procedures involving fewer levels (OR, 0.75; 95% CI, 0.65-0.86), and ambulation on the same day as surgery (OR, 0.65; 95% CI, 0.52-0.81) were associated with a decreased risk of POUR.Conclusions: Based on our meta-analysis, older age, male gender, BPH, DM, and a history of UTI are risk factors for POUR following elective spine surgery. We also found that longer operative time and increased intravenous fluid support would increase the risk of POUR. Additionally, multi-level spine surgery may have a negative effect on postoperative voiding. [ABSTRACT FROM AUTHOR]

Background: Postoperative urinary retention (POUR) is among the reasons for delay in discharge after outpatient total hip arthroplasty (THA), occurring in 2%-46% of patients. We hypothesized that the frequency of POUR following outpatient THA in the ambulatory surgery center (ASC) is low compared to previously reported rates and that management can be effective in the perioperative period when it is encountered.Methods: Three hundred seventy-seven THA patients (409 hips) who had arthroplasties in the ASC over a 5-year period were identified. Preoperatively, appropriate demographic information and medical comorbidities were collected from patient health history questionnaires completed during clinic visits. Intraoperatively, albumin volume administered and estimated blood loss were recorded. Postoperatively, post-anesthesia care unit medications, patients who reported an inability to urinate, and those who required urinary catheterization were recorded.Results: POUR occurred in only 2 patients but complaints of the inability to void occurred in 38 others for an incidence of 9.8%. Factors associated with POUR and the inability to urinate included older age, time spent in the ASC, and intraoperatively albumin volume administered. No significant differences were found in body mass index, preoperative hematocrit, estimated blood loss, surgical time, or operating time.Conclusion: POUR was infrequent but the reported inability to urinate was not (9.8%) and can be safely managed when it does occur and we found that increased age and albumin volume over 500 mL may increase the risk for a prolonged length of stay due to the inability to urinate.

Purpose: The rate of postoperative urinary retention (POUR) in laparoscopic inguinal hernia repairs is 1–22%. POUR may cause patient anxiety, discomfort, and increased hospital costs. Currently there is no standard prophylaxis for POUR. Preoperative administration of tamsulosin has been shown to decrease POUR rates in urologic studies. This study aims to evaluate the efficacy of tamsulosin on the incidence of POUR in patients undergoing totally extraperitoneal (TEP) LIHR. Methods: A randomized, double-blinded, placebo-controlled trial was initiated and accrued patients from 2017 to 2019. A total of 169 males undergoing elective TEP LIHR were included. Patients were administered tamsulosin 2 h before surgery and followed for up to 24 h postoperatively for episodes of POUR. Analysis was performed to quantify the association between patient, surgical, and perioperative factors with POUR. Results: The overall rate of POUR was 9%. There was no difference in the rate of POUR between the placebo (9.9%) and tamsulosin groups (7.9%) (p = 0.433). Univariate analysis showed a trend toward POUR in patients with history of benign prostatic hypertrophy (BPH) (p = 0.058). Previously reported risk factors of older age, total IVF, length of procedure and opioid use were not associated with increased rates of POUR. Tamsulosin reduced the time to discharge by 4 to 68 min when compared to placebo. Conclusions: This study suggests that preoperative administration of tamsulosin may not reduce the risk of POUR in males undergoing elective TEP LIHR. Further study with a larger sample size may be needed to show a statistically significant difference. [ABSTRACT FROM AUTHOR]

Introduction: Providing an adequate intraoperative anaesthesia with a prolonged pain-free interval is the prime priority of an anaesthesiologist. Since the decline in use of 2-chloroprocaine in 1956, due to side-effects of its preservative sodium bisulfite, the preservative free drug has recently witnessed a comeback in clinical practice. Aim: To compare the efficacy of bupivacaine and 2-chloroprocaine with and without fentanyl in subarachnoid block for inguinal hernia repair surgery. Materials and Methods: This randomised controlled study was carried out on 102 male patients of 18-65 years of age, American Society of Anesthesiologists (ASA) grade I or II, scheduled for inguinal hernia repair. The study was conducted from May 2019 to November 2020. The patients were randomly divided into three groups of 34 each. In group A, the subarachnoid block was administered with injection 0.5% bupivacaine (H) 10.5 mg. In group B, patients were administered, injection 2-chloroprocaine 40 mg diluted with 0.5 mL of saline. In group C, the patients were administered with injection 2-chloroprocaine 40 mg with 25 µg of injection fentanyl (0.5 mL). The adequacy of intraoperative anaesthesia in terms of onset and duration of sensory and motor blockade, haemodynamic parameters, postoperative urinary retention and other side-effects were evaluated. The parameters were compared using Analysis of variance test (>2 groups). If statistically significant difference was found in ANOVA, appropriate post-hoc (LSD/Bonferroni) was used to assess statistical significance of pair-wise comparisons. Results: The mean time of onset of the motor and sensory block was faster in Group B (3.57±0.66, 2.68±0.58 min), by almost 1 minute than in the Bupivacaine and Fentanyl group (4.57±0.79, 3.59±0.61 min) (4.99±1.01, 4.04±0.99 min) respectively. The mean difference was statistically significant (p-value <0.05). The mean duration of the motor and sensory blocks between the groups revealed statistically significant difference between groups A and B as well as Groups A and C. However, between Groups B and C, there was no significant difference as far as motor block duration is concerned. Group B had significantly shorter duration of the motor and sensory block amongst the three groups. Conclusion: Addition of intrathecal fentanyl significantly prolonged the onset and duration of sensory and motor block, with minimally extending the time to complete recovery. [ABSTRACT FROM AUTHOR]

Aims: To evaluate time to return of normal voiding function following native tissue vaginal reconstruction and evaluate risk factors for postoperative urinary retention (POUR). Methods: A retrospective cohort analysis of women undergoing vaginal reconstruction and suprapubic catheter with standardized regimen for voiding trials. Postvoid residual <150 ml at 4 h post catheter clamping was used as surrogate marker for return of bladder function. Univariate and multivariate regression analyses were used to identify risk factors for return of bladder function >4 days after surgery. Results: Between 2013 and 2018, 148 women underwent surgery, 124 were analyzed. Mean age was 67 years (±11.1), 62.9% (n = 78) had greater than or equal to stage 3 prolapse. Mean time to return of bladder function: 4.1 days (±3.1). Significant risk factors for >4 days to return of bladder function on univariate analysis included (mean ± SD): surgery length (150.4 min ±44.6) (odds ratio [OR], 1.24; confidence interval [CI], 1.12, 1.38); anesthesia length (228.1 min ±53.5) (OR, 1.12; CI: 1.04, 1.23); length of stay (2.2 days ±2.7) (OR, 2.43; CI: 1.11, 5.35); hysterectomy (OR, 3.10; CI: 1.39, 6.90); estimated blood loss (124.4 ml ±64.8) (OR, 1.39; CI: 1.04, 1.87). Postmenopausal status was protective (OR, 0.17; CI: 0.03, 0.92.). On multivariate analysis, significant findings were diabetes mellitus (OR, 0.18; CI: 0.04, 0.93) and surgery length (OR, 1.21; CI: 1.06, 1.38). Conclusions: Hysterectomy, surgical length and estimated blood loss were significantly associated with delayed return of bladder function after native tissue vaginal reconstruction. This data can help clinicians tailor postoperative voiding trials after failed initial attempt. [ABSTRACT FROM AUTHOR]
