Backflow of pathogens and endotoxins from the renal pelvis to the bloodstream is one supposed mechanism for infectious complications development after endourological stones surgery. The aim of this study is detecting to prove bacterial spread into irrigation fluid and bloodstream during percutaneous nephrolithotomy (PCNL) and to correlate these findings with clinical and microbiological parameters and infectious complications (IC).Bladder urine culture (BUC) was retrieved before PCNL; during the procedure, 2 blood samples (BC) and an irrigation fluid sample during fragmentation (SFUC) were collected for culture. Stone culture (SC) was also obtained. Patients were evaluated post-operatively for IC.Sixty-one patients were prospectively included. IC occurred in 15 patients (24.6%). SFUC was positive in 7/61 (11.5%); BC in 10/61 (16.4%). Among patients with positive BC; BUC, SFUC and SC were positive in 9 (90%), 6 (60%), and 8 (80%) cases, respectively. Out of 10 patients with positive BC, 4 developed post-operative IC. Pre-operative renal impairment (p = 0.04), intraoperative-evaluated stone residual (p = 0.02), BUC (p = 0.004), and SC (p = 0.008) were associated with IC. No correlation was found between bacterial spread in the irrigation fluid and blood and IC.We proved that bacteria can be detected into the irrigation fluid and blood during PCNL. This transient bacteremia appears to be unrelated to IC development.

BACKGROUND A correlation between atypical recurrences and minimally-invasive surgery has been suggested in case of urothelial cancer; however, very few data are available on the role of pneumo peritoneum in terms of gas flow and intra-abdominal pressure. The objective of the study is to analyze the impact of CO2 pneumoperitoneum variation on an inert material as surrogate of neoplastic cells. MATERIAL AND METHODS We designed an experimental model mimicking pneumoperitoneum in three settings: sealed flow (no leakage), pulsatile flow (alternating efflux and influx) and continuous flow (AirSeal® insufflator). Each experiment was characterized by a pre-determined gas flow and pressure, trocar distance and position from the particles. Hounsfield density (HD) variation in the areas of interest was measured as index of graphite powder dispersion. A Linear regression model was employed to measure the correlation between modifiable variables and HD. RESULTS HD was lower in the pulsatile compared to both the sealed and continuous flows (p 0.05). CONCLUSIONS Flow and pressure setting, in-flow trocar distance and contiguity from the tumor, and pneumoperitoneum stability may be all crucial component in minimally invasive surgery. In vivo, these variables should be considered as potential risk factors for tumor cells spread within the abdominal cavity.

Purpose: The three main treatment options for primary prostate cancer are surgery, radiation, and active surveillance. Surgical and radiation intervention for prostate cancer can be associated with significant morbidity. Therefore, accurate stratification predictive of outcome for prostate cancer patients is essential for appropriate treatment decisions. Nomograms that use clinical and pathologic variables are often used for risk prediction. Favorable outcomes exist even among men classified by nomograms as being at high risk of recurrence.Experimental Design: Previously, we identified a set of DNA-based biomarkers termed Genomic Evaluators of Metastatic Prostate Cancer (GEMCaP) and have shown that they can predict risk of recurrence with 80% accuracy. Here, we examined the risk prediction ability of GEMCaP in a high-risk cohort and compared it to a Kattan nomogram.Results: We determined that the GEMCaP genotype alone is comparable with the nomogram, and that for a subset of cases with negative lymph nodes improves upon it.Conclusion: Thus, GEMCaP shows promise for predicting unfavorable outcomes for negative lymph node high-risk cases, where the nomogram falls short, and suggests that addition of GEMCaP to nomograms may be warranted.

Introduction: Antegrade sclerotherapy (Tauber) effectively treats varicocele. However, fluoroscopy exposes young males to ionizing radiation. We aimed to evaluate radiation exposure and surgical outcomes after the Tauber procedure. Materials and methods: We retrospectively analysed data from 251 patients. Dose area product (DAP) and fluoroscopy time were recorded. The effective dose was calculated with the PCXMC software. Descriptive statistics and linear regression tested the association between clinical predictors and radiation exposure. Results: Median (IQR) age and body mass index (BMI) were 14 (13–16) years and 20.1 (17.9–21.6) kg/m². Five (2.1%) patients developed clinical recurrence and two (0.81%) developed complications. Median fluoroscopy time and DAP were 38.5 (27.7–54.0) s and 89.6 (62.5–143.9) cGy*cm2. The effective dose was 0.19 (0.14–0.31) mSv. Fluoroscopy time was higher in patients with collateral veins (41 (26–49) s vs. 36 (31–61) s, p = 0.02). The median amount of sclerosing agent (SA) used was 3 (3–4) ml. DAP was higher when SA > 3 mL was used (101.4 (65–183) cGy*cm2 vs. 80.5 (59–119) cGy*cm2; p < 0.01). At univariable linear regression, age, BMI, operative time and SA > 3 mL were associated with higher DAP (all p < 0.01). At multivariable linear regression, only BMI (beta 12.9, p < 0.001) and operative time (beta 1.9, p < 0.01) emerged as predictors of higher DAP, after accounting for age and SA > 3 mL. Conclusions: The Tauber procedure is safe and associated with low effective doses. Operative time and the patient’s BMI independently predict a higher radiation dose.

Purpose: To evaluate prevalence and predictors of trifecta in a cohort of patients treated with vacuum-assisted percutaneous nephrolithotomy (vamPCNL) for kidney stones. Methods: Data from 287 patients who underwent vamPCNL were analysed. Patient’s demographics, stones characteristics and operative data were collected. Stone-free was defined as no residual stones. Complications were recorded and graded according to modified Clavien classification. Trifecta was defined as stone-free status without complications, after a single session and no auxiliary procedures. Descriptive statistics and logistic regression models tested the association between predictors and trifecta outcome. Results: After vamPCNL, 219 (76.3%) patients were stone free and 81 (28.2%) had postoperative complications (any Clavien). Of 287, 170 (59.2%) patients achieved trifecta criteria. Patients who achieved trifecta status had smaller stone volume (pConclusion: Trifecta status was achieved in six out of ten patients after vamPCNL. Stones distribution in multiple caliceal groups and stone volume were independent unfavourable risk factors for trifecta.

OBJECTIVE To quantify and characterize the burden of urological patients admitted to emergency department (ED) in Lombardy during Italian COVID-19 outbreak, comparing it to a reference population from 2019. METHODS We retrospectively analysed all consecutive admissions to ED from 1 January to 9 April in both 2019 and 2020. According to the ED discharge ICD-9-CM code, patients were grouped in urological and respiratory patients. We evaluated the type of access (self-presented/ambulance), discharge priority code, ED discharge (hospitalization, home), need for urological consultation or urgent surgery. RESULTS The number of urological diagnoses in ED was inversely associated to COVID-19 diagnoses (95% confidence interval -0.41/-0.19; Beta = -0.8; P < .0001). The average access per day was significantly lower after 10 March 2020 (1.5 +/- 1.1 vs 6.5 +/- 2.6; P < .0001), compared to reference period. From 11 March 2020, the inappropriate admissions to ED were reduced (10/45 vs 96/195; P = .001). Consequently, the patients admitted were generally more demanding, requiring a higher rate of urgent surgeries (4/45 vs 4/195; P = .02). This reflected in an increase of the hospitalization rate from 12.7% to 17.8% (Beta = 0.88; P < .0001) during 2020. CONCLUSION Urological admissions to ED during lockdown differed from the same period of 2019 both qualitatively and quantitatively. The spectrum of patients seems to be relatively more critical, often requiring an urgent management. These patients may represent a challenge due to the difficult circumstances caused by the pandemic. (C) 2020 Elsevier Inc.

Background Bladder cancer (BC) usually metastasizes to the lymph nodes, bone, lung, liver and peritoneum, but rarely in the breast. Case report We present a case of a 66-year-old female diagnosed with a massive bladder tumor, who presented a right mammary nodule after neo-adjuvant chemotherapy. A biopsy of the nodule did not permit a definite diagnosis of metastatic spread, which was confirmed by excision of the nodule. In the literature, we found only 7 other similar cases of BC metastasis to the breast. Currently, a non-invasive method for differentiating a breast metastasis from primary cancer is lacking, although there are some clinical and radiological aspects that may help the diagnosis. Histological examination provides diagnostic certainty. Conclusion Breast metastases from BC are unusual and consequently difficult to identify without non-invasive tools. Clinical history and histological study play a pivotal role in determining the correct diagnosis.

Purpose To assess how accurate are urologists in predicting stone-free status (SFS) after vacuum-assisted mini-PCNL (vamPCNL) compared to computed tomography (CT) and clinical predictors of discordant SFS. Methods Data from 235 patients who underwent vamPCNL were analysed. Patient’s demographics, stones’ characteristics and operative data were recorded. SFS was evaluated intraoperatively by the treating urologist (iSFS) and with non-contrast CT 3 months after vamPCNL (ctSFS). SFS was defined as no residual stones. Stone complexity was scored with the Guy’s score. Descriptive statistics and logistic regression models were used to identify clinical factors associated with discordant SFS (namely iSFS not confirmed at CT). Results iSFS and ctSFS were 88.5% and 65.5%, respectively, with 54 (23%) cases resulting in discordant evaluation of SFS between the surgeon and CT imaging. Patients with discordant SFS had larger stone volume (p p = 0.03) and higher rate of multiple calyceal groups affected by stones (p p = 0.001). Multivariable logistic regression analysis revealed that stones in > 2 calyceal groups (OR 10.2, p p p = 0.02) were independent predictors of discordant SFS. Conclusion One out of five patients is erroneously considered SF after vamPCNL. Urologist should carefully evaluate patients with multiple calyceal stones and consider using flexible ureteroscopes to complete lapaxy of migrated fragments in order to improve their prediction of SFS.

Purpose We evaluated if, during lithotripsy, bacteria may be detected in the irrigation fluid of percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). The concordance between urine culture from stone fragmentation (SFUC), bladder (BUC), renal pelvic (RPUC) and stone (SC) was analyzed. We also assessed the correlation between variables and cultures and their association with systemic inflammatory response syndrome (SIRS) and of a positive SC. Methods We included 107 patients who underwent PCNL (n = 53) and RIRS (n = 54) from January 2017 to May 2018. Samples for RPUC were obtained by renal catheterization. Stone fragments and irrigation fluid sample were sent for culture. Results SFUC was positive in 17 (15.9%), BUC in 22 (20.6%), RPUC in 26 (24.3%) and SC in 30 patients (28%). The concordance between SFUC and SC was the highest among all cultures: 94.1%. SFUC and SC grew identical microorganisms in 15/17 (88.2%) patients. Out of 17 (15.9%) patients with SIRS, 8 (7.5%) had sepsis. SFUC had the highest PPV and specificity to detect positive SC and SIRS. Previous urinary tract infection, a preoperative nephrostomy, stone diameter and composition, staghorn calculi, PCNL, positive BUC, RPUC and SFUC were predictors of infected stone. Variables that indicate complex stones, complex PCNL and an infection of the upper tract were associated with SIRS. Conclusion SFUC is technically feasible, easy to retrieve and to analyze. The spectrum of SFUC potential application in clinical practice is when is not possible to perform a SC, e.g. complete dusting or during micro-PCNL.

Purpose To describe the vacuum-assisted mini-percutaneous nephrolithotomy (vmPCNL) technique performed via the 16Ch ClearPetra sheath, to evaluate its outcomes and to analyze intrarenal pressure (IRP) fluctuations during surgery. Methods Data from all consecutive vmPCNL procedures from September 2017 to October 2019 were prospectively collected. Data included patients’ and stones characteristics, intra and peri-operative items, post-operative complications and stone clearance. Patients undergoing vmPCNL from March to October 2019 were submitted to IRP measurement during surgery. Results A total of 122 vmPCNL procedures were performed. Median stone volume was 1.92 cm3. Median operative time was 90 min and median lithotripsy and lapaxy time was 28 min. Stone clearance rate was 71.3%. Thirty-one (25.2%) patients experienced post-operative complications, seven of which were Clavien 3. Postoperative fever occurred in nine (7.4%) patients and one (0.8%) needed a transfusion. No sepsis were observed. IRPs were measured in 22 procedures. Mean IRP was 15.3 cmH2O and median accumulative time with IRP > 40.78 cmH2O (pyelovenous backflow threshold) was 28.52 sec. Maximum IRP peaks were reached during the surgical steps when aspiration is closed (mainly pyelograms), whereas during lithotripsy and suction-mediated lapaxy, the threshold of 40.78 cmH2O was overcome in three procedures. Conclusions vmPCNL is a safe procedure with satisfactory stone clearance rates. Mean IRP was always lower than the threshold of pyelo-venous backflow and the accumulative time with IRP over this limit was short in most of the procedures. During lithotripsy and vacuum-mediated lapaxy, IRP rarely raised over the threshold.

Background A remote interaction between a console surgeon (CS) and a bedside surgeon (BS) makes the role of the latter critical. No conclusive data are reported about the length of the learning curve of a BS. Objective To highlight the role of a BS during robot-assisted radical prostatectomy (RARP) and to analyze the effect of the learning curve of a BS on intra- and postoperative outcomes. Design, setting, and participants From June 2013 to September 2016, 129 RARPs were performed by one expert CS (>1000 RARPs) and two BSs (residents). According to the learning curve of the BS, the patients were divided into three groups: group 1 (first 20 procedures), group 2 (21–40 procedures), and group 3 (>40 procedures). Outcome measurements and statistical analysis Preoperative variables, pathological data, operating time (OT), blood loss (BL), number of lymph nodes excised (LE), length of hospital stay (LHS), and time to catheter removal (CR) were analyzed. Linear/logistic regression analyses tested the impact of BS experience on surgical outcomes. T test and chi-square test compared the outcomes of the two BSs. Results and limitations Perfect interaction between CSs and BSs are requested to obtain the optimal exposure and avoid any conflict. On the linear regression model, BS learning curve was not related to OT, BL, LHS, and CR, but was related to LE ( r 2 = 0.09; p = 0.03). On multivariate analyses, no correlation between BS experience and OT, BL, LHS, CR, LE, margin status, and complications (all p > 0.05) was found. Comparing the two BSs, no difference was found for the abovementioned outcomes in the first 40 surgeries (all p > 0.05). Study limitations include the limited cohort of patients and its retrospective nature. Conclusions In this study, BS learning curve does not appear to influence the surgical outcomes; good experience of the CS was probably the explanation. Patient summary In our experience, it is the primary surgeon who dictates the perioperative outcomes during robot-assisted radical prostatectomy.

Purpose To validate the comprehensive complication index (CCI) for mini-percutaneous nephrolithotomy (mPCNL). Methods Data from 287 patients who underwent mPCNL were analyzed. Complications after mPCNL were classified using both the CCI and the Clavien–Dindo classification (CDC). Descriptive statistics and linear/logistic regression analyses detailed the association between clinical predictors and mPCNL outcomes. Results After mPCNL, 83 (28.9%) patients had complications, of which 12 (4.2%) patients with multiple complications had a higher CCI score compared to the traditional CDC system accounting only for the highest grade. The CCI enabled a more accurate prediction of length of stay (LOS) than CDC (CCI: r = 0.32; p r = 0.26; p = 0.01). Patients with multiple complications had higher stone volume (p = 0.02), longer operative time and LOS (all p p = 0.02) and lower rate of stone free (33.3% vs. 64.7%, p = 0.04) were found in patients with multiple complications than in those with single complication. Linear regression analysis revealed that multiple complications were associated with longer LOS (p p = 0.02). Conclusion The CCI is a valuable metric for assessing post-operative complications after mPCNL. The cumulative CCI is a better predictor of LOS than the CDC for mPCNL. Minor complications not captured by the highest CDC score are relevant since patients with multiple complications have longer LOS and higher rate of readmission than those with single ones.

Background Well-defined clinical predictors of sepsis after upper tract drainage for obstructive uropathy are lacking. The study aim is to develop a data driven score to predict risk of sepsis after decompression of the upper urinary tract. Materials and methods Complete clinical and radiological data from 271 patients entering the emergency department for obstructive uropathy and submitted to stent/nephrostomy tube decompression were evaluated. The Charlson Comorbidity Index (CCI) was used to score comorbidities. The definition of sepsis was an increase in ≥2 SOFA points (or postoperative persistently elevated score +1 additional increase) and documented blood or urine cultures. Descriptive statistics and stepwise multivariable logistic regression modelling with ROC analysis were performed in order to obtain a composite risk score to predict the risk of sepsis after surgery. Results Fifty-five (20.3%) patients developed sepsis. At multivariable analysis, CCI ≥2 (OR 3.10; 95%CI 1.36-7.04), max body temperature ≥38°C (OR 4.35; 95%CI 1.89-9.44), grade III-IV hydronephrosis (OR 2.37; 95%CI 1.10-4.98), Hounsfield units of the dilated collecting system ≥7.0 (OR 4.47; 95%CI 2.03-9.81), WBC ≥15x103/mmc (OR 2.77; 95%CI 1.24-6.19) and C-reactive protein ≥10 (OR 3.27; 95%CI 1.41-7.56) were independently associated with sepsis. The PPV of a true sepsis increased incrementally as a function of number of positive variables, ranging from 1.6% to 100.0% among patients with 1 and 6 positive variables, respectively. Conclusion Our risk score identifies accurately patients with an increased risk of sepsis after urinary decompression for obstructive uropathy, hence improving clinical management.

Background: Scoring metrics to assess and compare outcomes of percutaneous nephrolithotomy (PCNL) are needed. We aim to evaluate prevalence and predictors of trifecta in a cohort of patients treated with vacuum-assisted mini-percutaneous nephrolithotomy (vmPCNL) for kidney stones. Methods: Data from 287 participants who underwent vmPCNL were analysed. Patients’ and stones’ characteristics as well as operative data were collected. Stone-free was defined as no residual stones. The modified Clavien classification was used to score postoperative complications. Trifecta was defined as stone-free status without complications after a single session and no auxiliary procedures. Descriptive statistics and logistic regression models tested the association between predictors and trifecta outcome. Results: After vmPCNL, 219 (76.3%) patients were stone-free, and 81 (28.2%) had postoperative complications (any Clavien). Of 287, 170 (59.2%) patients achieved trifecta criteria. Patients who achieved trifecta status had smaller stone volume (p < 0.001), a higher rate of single stones (p < 0.001), shorter operative time (p < 0.01), and a higher rate of single percutaneous tract (p < 0.01) than −trifecta patients. Trifecta status decreased with the number of calyces involved, being 77.1%, 18.8%, and 4.1% in patients with 1, 2, or 3 calyces with stones, respectively (p < 0.001). Multivariable logistic regression analysis showed that stone volume (OR 1.1, p = 0.02) and multiple calyces being involved (OR 2.8 and OR 4.3 for two- and three-calyceal groups, respectively, all p < 0.01) were independent unfavourable risk factors for trifecta after accounting for age, BMI, gender, operative time, and number of access tracts. Conclusions: Trifecta status was achieved in 6 out of 10 patients after vmPCNL. Stone distribution in multiple calyceal groups and stone volume were independent unfavourable risk factors for trifecta.

Background: This study seeks to validate a radiological classification system of spontaneous upper urinary tract rupture (sUUTR) and to analyse its relationship with clinical, laboratory and radiological characteristics of sUUTR. Methods: We analysed data from 66 patients with a computerised tomography (CT)-proven sUUTR treated with ureteral or nephrostomy catheter positioning. Comorbidities were scored with the Charlson Comorbidity Index (CCI). All CT scans were reviewed by two experienced radiologists and one urologist, who classified sUUTR in (a) local spread, (b) free fluid and (c) urinoma. Interobserver agreement for radiological score was evaluated with the Intraclass Correlation Coefficient (ICC) and Cohen’s Kappa analyses. Descriptive statistics and logistic regression models verified the association between clinical variables and sUUTR severity. Results: The interobserver agreement for sUUTR classification was high among radiologists and between the radiologists and the urologist (all Kappa > 0.7), with an overall high interrater reliability (ICC 0.82). Local spread, free fluid and urinoma were found in 24 (36.4%), 39 (59.1%) and 3 (4.5%) cases, respectively. Patients with free fluid/urinoma had higher rate of CCI ≥ 1 than those with local spread (40.5% vs. 16.7%, p = 0.04). Intraoperative absence of urine extravasation was more frequently found in patients with local spread than those with free fluid/urinoma (66.7% vs. 28.6%, p < 0.01). Multivariable logistic regression analysis revealed that local spread (OR 4.5, p < 0.01) was associated with absence of contrast medium extravasation during pyelography, after accounting for stone size, fever and CCI. Conclusions: The analysed sUUTR classification score had good inter/intra-reader reliability among radiologists and urologists. Absence of urine extravasation was five times more frequent in patients with local spread, making conservative treatment feasible in these cases.

Purpose To perform a cost analysis between vacuum-assisted percutaneous nephrolithotomy (vmPCNL) and minimally invasive PCNL (MIP) and explore potential predictors of costs associated with the procedures. Methods We analyzed data from 225 patients who underwent vmPCNL or MIP at a single tertiary referral academic center between January 2016 and December 2020. We collected patients’ demographics, peri-and postoperative data and detailed expense records. After propensity score matching, 108 (66.7%) vmPCNL and 54 (33.3%) MIP procedures were analyzed. Descriptive statistics assessed differences in clinical and operative parameters. Univariable and multivariable linear regression models tested the association between clinical variables and costs. Results Operative time (OT) was shorter for vmPCNL, and the use of additional instruments to complete litholapaxy was more frequent in MIP (all p ≤ 0.01). Length of stay (LOS) was longer for MIP patients (p = 0.03) and the stone-free (SF) rate was higher after vmPCNL (p = 0.04). The overall instrumentation cost was higher for vmPCNL (p p = 0.9). However, the overall cost for the hospitalization was higher for MIP than vmPCNL (p = 0.01). Univariable linear regression revealed that patient’s comorbidities, OT, any postoperative complication and LOS were associated with hospitalization costs (all p p Conclusion vmPCNL may represent a valid option due to clinical and economic benefits. Shorter OT, the lower need for disposable equipment and the lower complication rate reduced procedural and hospitalization costs.

Background Percutaneous nephrolithotomy (PCNL) is the gold-standard for complex renal stones treatment in the pediatric population. While the miniaturization of PCNL reduces the risk of bleeding, it can hinder surgical and functional outcomes. The aim of the study is to assess the safety and feasibility of semiclosed-circuit vacuum-assisted Mini-PCNL (vmPCNL) in pediatric patients. Methods From January 2017 to December 2018, we prospectively collected data on consecutive vmPCNLs from two European tertiary referral centers. The procedure was performed with the ClearPetra® access sheath equipped with a lateral arm connected to the aspiration system (pressure setting ~ 120-150 cmH2O) by a 200 ml plastic stone collector. Pre-, intra- and post-operative data and costs were analyzed. The stone-free rate (SFR) was defined as absence of residual fragments > 4 mm with either ultrasound or kidney, ureter, and bladder x-ray. Results Eighteen vmPCNLs were performed in 16 renal units of 13 children. The median age was 119 months (IQR: 97-160) and the weight was 29 Kg (IQR: 25-40). The median cumulative stone size was 32 mm (22-46) with 8 (44.4%) cases of staghorn stones. The OT was 128 min (IQR: 99-167). The basketing was unnecessary in 6/18 (33%) cases. Neither intra-operative complications nor blood transfusions occurred. Post-operative fever was observed in 5/18 (27.8%) cases; in one case a double J ureteral stent was placed for concomitant hydronephrosis. The SFR was 81.3% (13/16), rising to 93.8% (15/16) after ancillary procedures. The materials costs of a vmPCNL (734.8 €) were comparable to mini-PCNL using a reusable set (710.7 €). Conclusions The vmPCNL seems to be sustainable, safe and feasible for kidney stones treatment in the pediatric population.

Currently available surgical treatments for Lower Urinary Tract Symptoms (LUTS) due to Benign Prostatic Obstruction (BPO) are associated with an increased risk of sexual dysfunction. The aim of our study is to compare sexual and ejaculatory function after Holmium Laser Enucleation of the Prostate (HoLEP) and Bipolar Transurethral Enucleation of the Prostate (B-TUEP). We performed a retrospective analysis of data prospectively collected from 62 (44.9%) and 76 (55.1%) patients who underwent HoLEP and B-TUEP, respectively. Erectile function and ejaculation characteristics were assessed with the International Index of Erectile Function-Erectile Function (IIEF-EF) domain and the Male Sexual Health Questionnaire-Ejaculatory function (MSHQ-EJ) questionnaires. Our study recorded no change in erectile function and no significant difference in rates of preserved antegrade ejaculation after both surgeries. One month after surgery, rates of physical pain/discomfort and perceived decreased physical pleasure during ejaculation were higher in HoLEP than B-TUEP patients (all p < 0.03). Moreover, HoLEP patients were more bothered by their ejaculatory difficulties than B-TUEP men (p = 0.03). At 3- and 12-months follow-up, all ejaculation-related differences disappeared. In conclusion, both procedures are valid alternatives for BPO treatment as they offer comparable urinary and sexual outcomes in the long term. However, in the first month after surgery, HoLEP patients present with more ejaculatory difficulties.

Background: The impact of surgical experience on radiation exposure (RE) during endourological procedures has been poorly investigated. Objective: To assess the impact of surgical experience on fluoroscopy time (FT) and RE during retrograde intrarenal surgery (RIRS). Design, setting, and participants: The study included 140 patients who underwent RIRS performed either by a senior surgeon (expertise of >100 RIRSs) (group A) or by two junior residents (expertise of

Objectives: To assess the safety and efficacy of bromelain plus tamsulosin versus tamsulosin alone as medical expulsive therapy (MET) for promoting spontaneous stone passage (SSP) of symptomatic distal ureter stones. Patients and Methods: One-hundred-fourteen patients with a 4–10 mm distal ureteral stone were enrolled (Group A). Patients self-administered daily bromelain with tamsulosin for 30 days or until SSP or intervention was mandatory. Patients were compared to those from a control group taking tamsulosin as MET (Group B) and matched for the following factors: sex, age ±10%, stone diameter. A logistic regression model evaluated bromelain and the ureteral stone diameter as explanatory variables. Results: SSP rates were 87.7 vs. 75.4% for group A vs. group B respectively (p = 0.016); with no difference observed for the time to self-reported stone expulsion (11.68 vs. 11.57 days; p = 0.91). Considering larger stones (> 5 mm), the SSP rate was 83.3% in group A and 61% in group B (p < 0.01). With each millimeter increment of stone diameter, the probability of SSP decreased by 59.1% (p < 0.0001), while it increased of 3.3 when bromelain was present. Only 3 cases of tamsulosin-related adverse events were recorded. Conclusion: The association of bromelain and tamsulosin as MET increases the probability of SSP of symptomatic distal ureteral stones, with no bromelain-related side effects recorded.

Hospital readmission rates have been analyzed due to their contribution to increasing medical costs. Little is known about readmission rates after urological procedures. We aimed to assess the incidence and predictors of 30-day readmission after discharge in patients treated with transurethral resection of the prostate (TURP). Data from 160 consecutive patients who underwent TURP from January 2015 to December 2016 were analysed. Intra hospitalization characteristics included length of stay (LOS), catheterization time (CT) and complications. Comorbidities were scored with the Charlson Comorbidity Index (CCI). Mean (SD) age was 70.1 (8.1) yrs and mean prostate volume was 80 (20.1) ml. Mean LOS and CT were 4.9 (2.5) days and 3.3 (1.6) days, respectively. The overall 30-day readmission rate was 14.4%, but only 7 (4.4%) patients required hospitalization. The most frequent reasons for readmission were haematuria (6.8%), fever/urinary tract infections (4.3%) and acute urinary retention (3.1%). Multivariable logistic regression analysis revealed age, CCI and CT to be independent predictors of readmission. However, when analysed according to age at the time of surgery, a beneficial effect from longer CT was observed only for patients older than 75 years. These parameters should be taken in account at the time of discharge after TURP.

Patient follow-up after transurethral resection of the prostate (TURP) is crucial to evaluate treatment-related outcomes and potential adverse events.
