Spinal cord injury (SCI) often leads to neurogenic lower urinary tract dysfunction, causing dysuria and affecting patients' well-being. This study aimed to evaluate the efficacy of a urethral sphincter botulinum toxin A (BoNT-A) injection in patients with SCI and dysuria. This was a retrospective study including 118 patients with SCI who underwent a urethral BoNT-A injection following a standardized protocol for refractory voiding dysfunction. The protocol involved injecting BoNT-A into the urethral sphincter under cystoscopic guidance. Patient demographics, bladder condition parameters, and treatment outcomes were analyzed. Logistic regression and receiver operating characteristic curve analyses were performed to identify predictors of treatment success. Of the 118 patients, 71 (60.1%) showed satisfactory treatment outcomes after the injection. Post-injection status, bladder management, and injection frequency varied significantly among patients with satisfactory and unsatisfactory treatment outcomes. Age, bladder compliance, intravesical pressure, and bladder contractility were indicators of satisfactory outcomes. The first sensation of bladder filling of ≤263 mL, intravesical pressure of ≤28, and bladder contractility index of ≥14 were highly correlated with satisfactory outcomes. A urethral sphincter BoNT-A injection shows promise in managing dysuria in patients with SCI. Understanding bladder condition parameters and patient demographics helps optimize patient selection for this intervention. Further studies are needed to validate these findings and refine treatment protocols. [ABSTRACT FROM AUTHOR]

Background: Multiple sclerosis (MS) is a chronic neurological disease characterized by inflammation, demyelinating and eventual neurodegeneration in the central nervous system. This can result in a variety of symptoms that markedly affect the patient's quality of life (QoL). One common manifestation of MS is voiding dysfunction. Therefore, this study was carried out to study the impact of voiding dysfunction on the QoL among MS patients. Methods: This cross-sectional study included 60 patients recruited from MS Outpatient Clinic of Neurology department at Zagazig University Hospitals and El Sheikh Zayed Al Nahyan Hospital, they were diagnosed as MS as per the 2017 Revised McDonald Diagnostic Criteria. We studied the relation between QoL and voiding dysfunction in MS patients using International Prostate Symptom Score (IPSS) as well as Multiple Sclerosis International Quality of Life (MusiQoL) scores. Results: Statistically significant differences were revealed between IPSS severity and all of activities of daily living (p=0.035), psychological wellbeing (p=0.007), symptoms (p=0.01), relation with friends (p=0.005), relation with family (p=0.037), coping (p=0.045) and MusiQoL index (p=0.004) (all were significantly lower in patients with moderate/severe IPSS score). Statistically significant negative correlations also were found between IPSS severity and all of psychological wellbeing (p=0.006), symptoms (p=0.011), relation with friends (p=0.025), relation with family (p=0.007), coping (p=0.014) and rejection (p=0.006), also highly significant negative correlations were revealed between IPSS severity with activities of daily living dimension score (p<0.001) and MusiQoL index (p=0.001). Conclusion: Various levels of severity of lower urinary tract symptoms (LUTS) (mild, moderate and severe) were observed among MS patients, with mild LUTS being predominantly observed. Findings indicated that the severity of LUTS is closely linked with reductions in various QoL dimensions. Particularly, patients with moderate to severe LUTS reported significantly lower QoL scores, underscoring the profound impact of urinary dysfunction on their daily lives and overall well-being.

Abstract Introduction and Objectives Voiding dysfunction remains a common side effect postprostate biopsy leading to significant morbidity. Alpha blockers have emerged as a potential therapeutic option to mitigate this risk, with various centres already incorporating its use in practice. Despite this, the literature regarding its efficacy remains inconclusive. Hence, a systematic review was performed to quantify the effect of perioperative alpha blockers on prostate biopsy‐related voiding function. Methods A systematic search in MEDLINE, Embase and PubMed between January 1989 and July 2023 was performed to identify relevant articles. Two independent reviewers independently screened abstracts, full texts and performed data extraction. Data including International Prostate Symptom Scores (IPSS), voiding flow rates (Qmax), postvoid residuals (PVR), rates of acute urinary retention (AUR) and quality of life (QoL) scores were extracted. Results were combined in an inverse variance random effects meta‐analysis. Results A total 808 patients from six randomised controlled trials (RCTs) comparing alpha blockers to controls were included. All articles excluded patients with pre‐existing voiding dysfunction. Pooled outcomes demonstrated statistically significant differences favouring alpha blocker usage in all objective and subjective measures including IPSS (mean difference 4.21, 95% confidence interval [CI] 2.58–5.84, p

Stretch-activated two-pore domain K+ (K2P) channels play important roles in many visceral organs, including the urinary bladder. The TWIK-related K+ channel TREK-1 is the predominantly expressed K2P channel in the urinary bladder of humans and rodents. Downregulation of TREK-1 channels was observed in the urinary bladder of patients with detrusor overactivity, suggesting their involvement in the pathogenesis of voiding dysfunction. This study aimed to characterize the long-term effects of TREK-1 on bladder function with global and smooth muscle-specific TREK-1 knockout (KO) mice. Bladder morphology, bladder smooth muscle (BSM) contractility, and voiding patterns were evaluated up to 12 mo of age. Both sexes were included in this study to probe the potential sex differences. Smooth muscle-specific TREK-1 KO mice were used to distinguish the effects of TREK-1 downregulation in BSM from the neural pathways involved in the control of bladder contraction and relaxation. TREK-1 KO mice developed enlarged urinary bladders (by 60.0% for males and by 45.1% for females at 6 mo; P < 0.001 compared with the age-matched control group) and had a significantly increased bladder capacity (by 137.7% at 12 mo; P < 0.0001) and compliance (by 73.4% at 12 mo; P < 0.0001). Bladder strips isolated from TREK-1 KO mice exhibited decreased contractility (peak force after KCl at 6 mo was 1.6 ± 0.7 N/g compared with 3.4 ± 2.0 N/g in the control group; P = 0.0005). The lack of TREK-1 channels exclusively in BSM did not replicate the bladder phenotype observed in TREK-1 KO mice, suggesting a strong neurogenic origin of TREK-1-related bladder dysfunction. NEW & NOTEWORTHY: This study compared voiding function and bladder phenotypes in global and smooth muscle-specific TREK-1 KO mice. We found significant age-related changes in bladder contractility, suggesting that the lack of TREK-1 channel activity might contribute to age-related changes in bladder smooth muscle physiology.

Objective: Voiding Dysfunction (VD) is one of the most common disorders among women, which is characterized by a disorder in urination. Pelvic organ prolapse is one of the factors that can affect VD. In this study, the relationship between prolapse in the anterior, posterior, and apical areas and VD has been evaluated. Materials and methods: This is a cohort retrospective study. The participants in this study were women with VD, who referred to the pelvic floor disorders clinic of Imam Khomeini Hospital in Tehran in 2018-2020. Clinical information was obtained retrospectively from the hospital's electronic data system, also symptoms (intermittent stream, incomplete voiding, poor flow, post void dribble, straining to void, stage anterior, posterior and apical) and urodynamic parameters (including EMG, PVR100, Qmax12, and pdet20) were evaluated, which included detailed questionnaires (Urinary Distress Inventory 6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7)), pelvic examination, and complete urodynamic evaluation. Results: There was a direct relationship between the age of the patients and the stage of prolapse (p<0.001). So that, the stage increased with age. In addition, it was found that the severity of urinary symptoms is related to the stage of prolapse in the apical area (p=0.001). Also, the results showed that intermittent stream symptoms and the symptoms of staining to void had a significant relationship with the stage of prolapse (III and IV) in the apical and anterior areas. Also, it was shown that only PVR > 100 had a significant relationship with the stage of prolapse in the apical area (p=0.001). Conclusion: Intermittent stream and straining to void were related to the stages of prolapse in the apical and anterior regions. It was also concluded that the greater the prolapse, the higher the value of PVR > 100. [ABSTRACT FROM AUTHOR]

- Abstract
Pediatric patients with lower urinary tract dysfunction (LUTD) experience a variety of medical and psychosocial concerns that can negatively impact their clinical management and quality of life. When initially described by Drs Hinman and Baumann, patients with a form of severe LUTD, later dubbed Hinman syndrome, were characterized as having a "general attitude of being failures." While this mention was noteworthy as it incorporated an understanding of the interplay between psychological factors and urologic conditions, there have been delays in implementing psychological intervention as a standard of care in patients with LUTD broadly, and perhaps too keen of a focus on youth diagnosed with Hinman syndrome specifically. A non-systematic reviewed of LUTD related to psychological management was performed. Clinical recommendations were developed by a multicenter and multidisciplinary team of care providers with topic expertise. The aim of this paper is to propose a systems thinking paradigm for how to involve psychology, or psychological principles, across the spectrum of patients with LUTD with the hope of improving attention to specific aspects of care that may improve clinical management. Children across the spectrum of LUTD are likely to benefit from psychological interventions and would benefit from such involvement early on to mitigate the impact of psychosocial concerns on medical outcomes. Pediatric psychologists are well-suited to identify and provide individualized care to patients in greatest need of intervention, such as through pre-procedural preparedness, addressing non-adherence, and with the use of evidence-based, targeted mental health interventions. Psychologists are also apt at implementing interventions while taking into consideration the severity of LUTD, in the context of the patient's psychological, developmental, cultural, familial, and social determinants of health considerations. Youth with severe forms of LUTD, such as Hinman syndrome, likely exemplify the challenges of LUTD that benefit from multidisciplinary intervention. Medical and psychological collaboration are key to ensuring symptom mitigation and emotional support for patients across the entire spectrum of LUTD. [ABSTRACT FROM AUTHOR]

- Abstract
Objective Methods Results Conclusion Female voiding dysfunction with cystocele have been widely studied, but there are no data regarding women without cystoceles. The present study aimed to evaluate the prevalence of detrusor underactivity (DU) and bladder outlet obstruction (BOO) without cystoceles in a large sample size.This was a retrospective cohort study. Between April 1996 and September 2018, 602 neurologically intact women with voiding dysfunction without cystoceles were enrolled. Detrusor pressure (DU) at the maximum flow rate (PdetQmax) <20 cmH2O, maximum flow rate (Qmax) <15 mL/s, and a bladder voiding efficiency <90% and BOO (PdetQmax ≥40 cmH2O and Qmax <12 mL/s) were diagnosed by urodynamic study. Otherwise, a non‐DU/BOO diagnosis was made. The prevalence of DU and BOO was the primary outcome. The secondary outcomes were the analyses of the differences between these three groups in objective UDS parameters and subjective questionnaires and bladder diary parameters.This study included 100 (17%) women with DU, 60 (10%) with BOO, and 442 (73%) with a non‐DU/BOO diagnosis. DU increased with age, but BOO decreased as age increased. The women in the DU group were older, had higher parity and pad weights, and lower PdetQmax, maximum urethral closure pressure, and functional profile length than the BOO group. The urodynamic findings did not correlate well to subjective questionnaire parameters. None of the symptoms revealed a significant difference between the groups. The retrospective design was the limitation of the study.The prevalence of DU increased with age in women with voiding dysfunction without advanced cystoceles. Conversely, BOO decreased with age. Prevalence intersected in the fourth decade. Diagnosis requires urodynamic evaluation, as subjective symptoms are inconclusive. [ABSTRACT FROM AUTHOR]

Clean intermittent self-catheterisation (CISC) is considered the preferred option to an indwelling catheter for emptying the bladder in people with a range of voiding dysfunctions. CISC has a lower risk of complications and urinary tract infections. This narrative review of previous qualitative research explores the quality-of-life impacts and highlights the challenges that men face. It will provide nurses who teach CISC with some useful insights into the male experience and the issues of concordance and adherence. This will help to better inform and guide clinical practice in this specialist area of nursing practice. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To retrospectively compare the efficacy and technical performance of a novel lead used for percutaneous nerve evaluation (PNE) during the testing phase for sacral nerve neuromodulation with the existing lead currently used. Materials and methods: Sixty-three PNE leads were inserted in 45 consecutive patients who underwent PNE with the novel helical electrodes, and the intra-operative and return clinic sensory threshold currents were recorded. This resulted in current measurements for 63 individual electrodes. Measurements were compared with 46 consecutive patients who previously underwent PNE using the standard lead with measurements for 63 individual electrodes. Current difference distributions for the two leads were compared using a Wilcoxon signed-rank test. Results: There was a statistically significant difference observed between the two types of PNE electrode. The new PNE lead demonstrated less drift in sensory threshold current during a 12-day test period in comparison to the old lead. Conclusion: The novel helical PNE electrodes demonstrate a significant improvement in current drift compared with the old style leads over a 12-day test period. Level of evidence: Level III [ABSTRACT FROM AUTHOR]

Objective: To compare perioperative morbidity, functional and quality‐of‐life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. Patients and Methods: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998–2021) was conducted in a single centre. Study outcomes included postoperative complications, quality‐of‐life, functional and stoma‐related outcomes. The 36‐item Short‐Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy‐Colorectal questionnaires and Distress Thermometer were available pre‐ and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. Results: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound‐related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long‐term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post‐voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. Conclusions: Partial cystectomy patients have fewer postoperative wound‐related complications than radical cystectomy patients, but often experience long‐term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery. [ABSTRACT FROM AUTHOR]

- Abstract
The main problems of neurogenic lower urinary tract dysfunction (NLUTD) in patients with spinal cord injury (SCI) consist of impaired urine storage, impaired bladder emptying, or both. The priorities in the management of SCI–NLUTD should be preservation of renal function, followed by freedom from urinary tract infections and improvement of quality of life. Management of NLUTD in patients with SCI must be based on urodynamic findings rather than clinical evaluations. In the hospital without urodynamic equipment, careful measurement of intravesical pressure and safety functional bladder capacity in conjunction with clinical assessment are also feasible. Identification of high-risk patients is important for preventing urological complications in patients with chronic SCI. The management of NLUTD should start with conservative bladder management and medical treatment. Patients with SCI should be regularly followed up, and any NLUTDs and urological complications should be adequately treated. When surgical intervention is necessary, less invasive and reversible procedures should be considered first, and any unnecessary surgery should be avoided. This article reports the current evidence and expert opinions on the patient-centered bladder management of NLUTD in chronic SCI patients in Taiwan. To avoid renal function deterioration and urological complications, annual active surveillance of bladder and renal function is mandatory, especially for high-risk SCI patients.

Voiding dysfunction and non-obstructive urinary retention are common conditions with debilitating patient symptoms. Treatment of these conditions can be challenging with limited conservative options available. Sacral Neuromodulation is a minimally invasive treatment which has been demonstrated to deliver good success rates in this patient population. It provides patients with a trial period to establish the likelihood of treatment success prior to implantation of a full system and can be reversed should the need arise.This review looks at the potential mechanisms of action of Sacral Neuromodulation in patients with voiding dysfunction or non-obstructive urinary retention, along with the literature evaluating success rates both in the short and long term. It aims to examine any possible predictive factors that may play a role in guiding patient selection and improving patient counselling. It also addresses gaps in the literature and areas where further research is needed.

- Abstract
To determine the outcome of voiding function 1 year after pelvic reconstructive surgery (PRS) in women with bladder outlet obstruction (BOO). Retrospective cohort study. Tertiary referral hospital. A total of 1894 women underwent PRS for advanced pelvic organ prolapse (POP) stages 3 to 4 with urodynamic findings of BOO. PRS. The primary outcome measured was the resumption of normal voiding function, defined clinically with multichannel urodynamic testing at 1 year postoperatively. The secondary outcomes were to identify the different risk factors for persistence voiding dysfunction (VD) 1 year after PRS. A total of 431 women with Pelvic Organ Prolapse Quantification stages 3 and 4, urodynamic study of maximum urinary flow rate ≤15 mL/s, and detrusor pressure at maximum flow ≥20 cm H 2 O were included. Resumption of normal voiding function was found in 91% (n = 392 of 431), whereas 9% (n = 39 of 431) remained to have VD 1 year postoperatively. Those with persistent VD, 20.5% (n = 8 of 39) remained having urodynamic diagnosis of BOO. Univariate and multivariate logistic regression revealed factors associated with postoperative VD were pre-operative maximal cystometric capacity ≥500 mL and postvoid residual volume ≥200 mL. VD may persist in women with BOO after PRS, particularly in those with preoperative maximal cystometric capacity of >500 mL and postvoid residual volume >200 mL. [ABSTRACT FROM AUTHOR]

Aim: To epidemiologically determine post‐void residual urine volume (PVR) and identify the characteristics of "potential" older adult patients with voiding dysfunction in an acute‐care hospital. Methods: A cross‐sectional study was conducted on 614 older adult patients in an acute‐care hospital between November 2018 and May 2019. Using portable ultrasound devices, nurses measured the patients' PVR three times after admission. Lower urinary tract symptoms were evaluated using the Core Lower Urinary Tract Symptom Score prior to admission. Results: A total of 107 older adult patients (17.4%) had episodes of abnormal PVR ≥100 mL. An age of over 75 years (adjusted odds ratio [aOR]: 1.899) and feeling of incomplete emptying (aOR: 4.337) were associated with having at least one episode of abnormal PVR, whereas neurological or circulatory diseases (aOR: 3.699) were associated with having two or three episodes. Conclusions: The results showed a high prevalence of abnormal PVR in older adult patients. Screening for PVR in older adult patients aged over 75 years who experience incomplete emptying or neurological or circulatory diseases may help identify those at risk for voiding dysfunction.

Spinal cord injury (SCI) often leads to neurogenic lower urinary tract dysfunction, causing dysuria and affecting patients’ well-being. This study aimed to evaluate the efficacy of a urethral sphincter botulinum toxin A (BoNT-A) injection in patients with SCI and dysuria. This was a retrospective study including 118 patients with SCI who underwent a urethral BoNT-A injection following a standardized protocol for refractory voiding dysfunction. The protocol involved injecting BoNT-A into the urethral sphincter under cystoscopic guidance. Patient demographics, bladder condition parameters, and treatment outcomes were analyzed. Logistic regression and receiver operating characteristic curve analyses were performed to identify predictors of treatment success. Of the 118 patients, 71 (60.1%) showed satisfactory treatment outcomes after the injection. Post-injection status, bladder management, and injection frequency varied significantly among patients with satisfactory and unsatisfactory treatment outcomes. Age, bladder compliance, intravesical pressure, and bladder contractility were indicators of satisfactory outcomes. The first sensation of bladder filling of ≤263 mL, intravesical pressure of ≤28, and bladder contractility index of ≥14 were highly correlated with satisfactory outcomes. A urethral sphincter BoNT-A injection shows promise in managing dysuria in patients with SCI. Understanding bladder condition parameters and patient demographics helps optimize patient selection for this intervention. Further studies are needed to validate these findings and refine treatment protocols.

- Abstract
Purpose of Review: The current literature available to providers on urgency urinary incontinence in orthotopic neobladder patients will be reviewed. Recent Findings: In this review, we will examine the most recent studies evaluating potential therapies for urgency urinary incontinence in neobladder patients. Summary: Urgency urinary incontinence in patients with neobladders is a challenging symptom to manage for both patients and providers, both due to the pathophysiology as well as a lack of data on effective therapies. Given the similar symptom profile to patients with overactive bladder as well as comparable functional derangement to irritable bowel syndrome, we explore the potential use of traditional overactive bladder and irritable bowel syndrome therapies in this patient population. Further study is needed in the diagnostic workup and management in urgency neobladder urinary incontinence. [ABSTRACT FROM AUTHOR]

Hartman-Kenzler, Jacob, Pizzuti, Joseph, and Kim, Jason
- Abstract
Purpose of Review: Overactive bladder (OAB) is a prevalent condition affecting 23% of the population in the USA. There are several options for third-line therapies (intradetrusoronabotulinumtoxinA injections, sacral (S3) nerve stimulation, and posterior tibial nerve stimulation (PTNS)), each with its own strengths and weaknesses. Recent Findings: Implantable tibial nerve stimulators (ITNS) are a new type of device based on PTNSprinciples; however, ITNS may carry several advantages over previous therapeutic modalities. Typically, ITNS is an office-based procedure obviating the need for general anesthesia or sedation. There is no need for frequent office visits or repeat procedures (as with intradetrusoronabotulinumtoxinA injections) once these devices are implanted. Summary: ITNS stimulators have enabled a much more flexible system of administering and managing tibial nerve stimulation. Not only does ITNS offer convenience, but it offers the ability to manipulate the frequency, length, and strength of stimulation sessions. This review describes the current available devices, published clinical data, and ongoing clinical trials for future devices. [ABSTRACT FROM AUTHOR]

Urine samples of female patients with overactive bladder (OAB) are characterized by low levels of nerve growth factor (NGF) and elevated concentrations of nitric oxide (NO) compared to healthy controls. We therefore examined how NO might regulate NGF synthesis using rat bladder smooth muscle (SMCs) and urothelial (UROs) cells in culture. In UROs, incubation in hyperglycemic conditions to mimic insulin insensitivity present in the OAB cohort increased secretion of NO and concomitantly decreased NGF, except when the NO synthase inhibitor, l -NAME (1 mM) was present. Sodium nitroprusside (SNP) (300 μM, 24 h), a NO generator, decreased NGF levels and decreased cyclic GMP (cGMP) content, a process validated by the cGMP synthase inhibitor ODQ (100 μM). Alternatively, SNP increased mRNA of both NGF and matrix metalloproteinase-9 (MMP-9). MMP-9 knockout of UROs by Crispr-Cas9 potently decreased the effect of SNP on NGF, implying a dependent role of NO on MMP-9. On the other hand, matrix metalloproteinase-7 (MMP-7) activity was increased by SNP, which taken together with increase in NGF mRNA, suggests a compensatory mechanism. In SMCs, hyperglycemic conditions had the same effect on extracellular content of NO and NGF than in UROs. SNP also decreased NGF secretion but increased cGMP content. Stable permeable analogs of cGMP 8-(4-Chlorophenylthio)-cGMP (1 mM) and N2,2′-O-Dibutyryl-cGMP (3 mM) inhibited NGF release. NGF and MMP-9 mRNA expression was unchanged by SNP. Deletion of MMP-9 in SMCs by Crispr-Cas9 did not alter the effect of SNP. Finally, SNP decreased MMP-7 activity, diminishing the conversion of proNGF to NGF. These results demonstrate that enhanced NO secretion triggered by high glucose decreases NGF secretion through pathways unique for each cell type that involve cGMP and proteases MMP-7 and MMP-9. These results might help to explain our observations from the urine from patients with OAB associated with metabolic syndrome. • Hyperglycemic medium increases the release of nitric oxide by bladder cells. • Nitric oxide decreases the release of mature nerve growth factor. • Changes in cyclic GMP is required to mediate nitric oxide action. • Matrix metalloproteinases 7 and 9 are involved in neurotrophin proteolysis.

Aims: The Working Group (WG), initiated by the International Continence Society (ICS) Standardisation Steering Committee and supported by the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction, has revised the ICS Standard for pressure‐flow studies of 1997. Methods: Based on the ICS standard for developing evidence‐based standards, the WG developed this new ICS standard in the period from May 2020 to December 2022. A draft was posted on the ICS website in December 2022 to facilitate public discussion and the comments received have been incorporated into this final release. Results: The WG has recommended analysis principles for the diagnosis of voiding dysfunction for adult men and women without relevant neurological abnormalities. New standard terms and parameters for objective and continuous grading of urethral resistance (UR), bladder outflow obstruction (BOO) and detrusor voiding contraction (DVC) are introduced in this part 2 of the standard. The WG has summarized the theory and recommendations for the practice of pressure‐flow study (PFS) for patients in part 1. A pressure‐flow plot is recommended for the diagnosis of every patient, in addition to time‐based graphs. Voided percentage and post void residual volume should always be included in PFS analysis and diagnosis. Only parameters that represent the ratio or subtraction of pressure and synchronous flow are recommended to quantify UR and only parameters that combine pressure and flow in a product or sum are recommended to quantify DVC. The ICS BOO index and the ICS detrusor contraction index are introduced in this part 2 as the standard. The WG has suggested clinical PFS dysfunction classes for male and female patients. A pressure‐flow scatter graph including every patient's pdet at maximum flow (pdetQmax) with maximum flow rate (Qmax) point should be included in all scientific reports considering voiding dysfunction. Conclusion: PFS is the gold standard used to objectively assess voiding function. Quantifying the dysfunction and grading of abnormalities are standardized for adult males and females.

Aims: The working group (WG) initiated by the International Continence Society Standardization Steering Committee and supported by the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction has revised the (1997) ICS Standard for pressure flow studies. Methods: Based on the ICS standard for developing evidence‐based standards, the WG developed this new ICS standard in the period from May 2020 to December 2022. A draft was posted on the ICS website in January 2023 to facilitate public discussion and the comments received have been incorporated into this final release. Results: The WG summarizes the theory and recommends the practice and the terms used for the diagnosis of voiding dysfunction for adult female and male patients without relevant neurological abnormalities, in part 1 of this standard. The WG has also recommended standard principles and parameters for objective and continuous grading of urethral resistance and detrusor voiding contraction on the basis of pressure flow studies in part 2. The recommendations for practice in this part have also the aim to increase the understanding of the physiology as well as the psychology of voiding. The potential effects of the laboratory situation of the test on the voiding as well as the role of the urodynamicist in this regard are discussed. The WG has recommended to use for diagnosis only the voidings that are considered representative by the patient. Conclusion: A pressure flow study is the gold standard to assess voiding function and to quantify dysfunction. This part of the standard explains the clinical background, gives recommendations for the execution of a pressure flow study and lists relevant terms, parameters, and units of measurements.

- Abstract
Uroflowmetry is a non-invasive study used in the diagnosis and monitoring of treatment response for lower urinary tract disorders. For optimal clinical utility, uroflow studies rely on careful clinical interpretation by a trained provider, but currently there is a lack of accepted standardized normal values for the measured uroflow parameters in children. The International Children's Continence Society proposed standardizing the terminology for uroflow curve shapes. However, the patterning of curves is largely at the physician's subjective discretion. The aims of this study were to understand inter-rater reliability in interpreting uroflow curves and to define characteristics of uroflow curves that could be used to provide definitive criteria for uroflowmetry parameters. All members of the SPU Voiding dysfunction Task Force were invited to contribute deidentified uroflows to a centralized HIPAA complaint receiving database. All studies were then distributed to all raters for review. Each observer's findings were recorded according to ICCS criteria (ICCS), additional readings were done using a previously reported system which defined curves as smooth or fractionated (SF) and whether the shape resembled a bell, tower, or plateau (BTP). Flow indexes (Qact/Qest) (FI) for Qmax and Qavg were generated using formulas previously reported for children 4–12 and for patients≥12 years. A total of 119 uroflow studies were read by 7 raters and curves were contributed from 5 sites. Kappa scores for the 5 readers from different institutions were 0.34 and 0.28 for the ICCS and BTP methods, respectively (both considered fair agreement). Kappa for smooth and fractionated curves was 0.70 (for each; considered substantial agreement), which were the two highest agreement scores obtained throughout the study. Discriminant analysis (DA) revealed that the FI Qmax was the dominant vector, and that the ICCS uroflow parameters have a total of 42.8% prediction rate in the training sample. Using DA of a smooth/fractionated system, the total prediction rates were 72% and 65.5% for smooth and fractionated, respectively. Given the poor inter-rater agreement for analyzing uroflow curve pattern based on ICCS criteria in this study and others, one may find it reasonable to consider alternative approaches to describing and characterizing uroflow curves. Our study is limited by lack of EMG and post-void residual data. For a more objective uroflow interpretation and comparison of studies among different centers, we recommend using our proposed system (based on FI, and smooth vs. fractionated curve pattern), which is more reliable.

Purpose This is the first report to compare 3-dimensional computed tomography (3D-CT) images between pediatric patients with enuresis and children without lower urinary tract symptoms who underwent pelvic CT for other reasons. Methods Forty-seven children (33 boys and 14 girls) with primary enuresis underwent 3D-CT of sacrococcygeal bones. The control group consisted of 138 children (78 boys and 60 girls) who underwent pelvic CT for other reasons. First, we determined the presence or absence of unfused sacral arches at the L4-S3 levels in both cohorts. Subsequently, we compared the fusion of sacral arches in age- and sex-matched children from these 2 groups. Results Dysplastic sacral arches, characterized by lack of fusion at 1 or more levels of the S1–3 arches, were observed in nearly all patients in the enuresis group. In the control group (n=138), 54 of 79 children over 10 years old (68%) exhibited fused sacral arches at 3 S1–3 levels. All 11 control children under 4 years old displayed at least 2 unfused sacral arches at the S1–3 levels. In a comparative study of age- and sex-matched patients with enuresis and control children aged 5 to 13 years (n=32 for each group, with 21 boys and 11 girls; mean age, 8.0±2.2 years [range, 5–13 years]), only 1 patient (3%) in the enuresis group exhibited fusion of all S1–3 arches. In contrast, 20 of 32 control group participants (63%) had 3 fused sacral arches (P

Abstract Introduction Machine learning (ML) is an established technique that uses sets of training data to develop algorithms and perform data classification without using human intervention/supervision. This study aims to determine how functional and anatomical brain connectivity (FC and SC) data can be used to classify voiding dysfunction (VD) in female MS patients using ML. Methods Twenty‐seven ambulatory MS individuals with lower urinary tract dysfunction were recruited and divided into two groups (Group 1: voiders [V, n = 14]; Group 2: VD [n = 13]). All patients underwent concurrent functional MRI/urodynamics testing. Results Best‐performing ML algorithms, with highest area under the curve (AUC), were partial least squares (PLS, AUC = 0.86) using FC alone and random forest (RF) when using SC alone (AUC = 0.93) and combined (AUC = 0.96) as inputs. Our results show 10 predictors with the highest AUC values were associated with FC, indicating that although white matter was affected, new connections may have formed to preserve voiding initiation. Conclusions MS patients with and without VD exhibit distinct brain connectivity patterns when performing a voiding task. Our results demonstrate FC (grey matter) is of higher importance than SC (white matter) for this classification. Knowledge of these centres may help us further phenotype patients to appropriate centrally focused treatments in the future.

Introduction and hypothesis: Of women with symptomatic prolapse, 13–39% experience voiding dysfunction (VD). The aim of our observational cohort study was to determine the effect of prolapse surgery on voiding function. Methods: Retrospective analysis of 392 women who underwent surgery between May 2005 and August 2020. All had a standardized interview, POP-Q, uroflowmetry and 3D/4D transperineal ultrasound (TPUS) pre-and postoperatively. Primary outcome was change in VD symptoms. Secondary outcomes were changes in maximum urinary flow rate (MFR) centile and post-void residual urine (PVR). Explanatory measures were change in pelvic organ descent as seen on POP-Q and TPUS. Results: Of 392 women, 81 were excluded due to missing data, leaving 311. Mean age and BMI were 58 years and 30 kg/m2, respectively. Procedures performed included anterior repair (n = 187, 60.1%), posterior repair (n = 245, 78.8%), vaginal hysterectomy (n = 85, 27.3%), sacrospinous colpopexy (n = 170, 54.7%) and mid-urethral sling (MUS) (n = 192, 61.7%). Mean follow-up was 7 (1–61) months. Pre-operatively, 135 (43.3%) women reported symptoms of VD. Postoperatively, this decreased to 69 (22.2%) (p < 0.001), and of those, 32 (10.3%) reported de novo VD. The difference remained significant after excluding concomitant MUS surgery (n = 119, p < 0.001). Postoperatively, there was a significant decrease in mean PVR (n = 311, p < 0.001). After excluding concomitant MUS surgery, there was a significant increase in mean MFR centile (p = 0.046). Conclusions: Prolapse repair significantly reduces symptoms of VD and improves PVR and flowmetry. [ABSTRACT FROM AUTHOR]

We aimed to identify risk factors for postoperative voiding dysfunction following tension-free vaginal tape (TVT) or trans obturator tape (TOT). A retrospective case-control study was conducted on patients who underwent mid-urethral sling procedures over a four-year-period by the same surgical team. The patients were divided into two groups. Patients who needed to loosen the tape materials surgically before being discharged due to persistent postvoid residual bladder volume =150 ml and/or difficulty in emptying the bladder were described as postoperative voiding dysfunction (case group). The patients who did not need it were the control group. Demographic information, voiding symptoms, urodynamic evaluation, and intraoperative data were collected from the hospital's medical records. Of 167 patients, 29 (17.4%) were in the case group and 138 (82.6%) were in the control group. At univariate analysis, age, menopausal status, preoperative valsalva leak point pressure measurement, presence of preoperative = grade 3 pelvic organ prolapse, TVT procedure, concomitant anterior colporrhaphy, and vaginal hysterectomy were associated with voiding dysfunction. Multivariate logistic regression revealed that menopausal status, TVT procedure, and concomitant anterior colporrhaphy were significant predictors of postoperative voiding dysfunction. The present study indicated that postoperative voiding dysfunction is more often after TVT than after TOT procedures. Menopausal status and concomitant anterior colporrhaphy increased the risk of postoperative voiding dysfunction. Recognition of these risk factors may enable surgeons to minimize this complication.

A rectal prolapse is mainly a disease of the elderly population, occurring more frequently among women. The medical practitioner has an important role in the recognition and initiation of therapy for rectal prolapse. Appropriate therapy can have an important impact on symptom reduction and healthcare resources. Surgical therapy includes perineal or transabdominal surgery, with increasing use of minimally invasive techniques such as mesh rectopexy. This operation is indicated and feasible regardless of age. The management of the rectal prolapse in specialized pelvic floor centres with interdisciplinary expertise for diagnosis and therapy is recommended. [ABSTRACT FROM AUTHOR]

- Abstract
Robot-assisted VVF (RA-VVF) repair has the advantage of small cystotomy, precise dissection and minimal surrounding tissue trauma. Translation of this to better functional outcomes is not studied so far. This study aims to evaluate the quality of life, voiding, and sexual dysfunction following robot-assisted VVF repair. Women with successful RA-VVF repair were screened using UDI-6, IIQ-7, FSFI, and WHOQOL-BREF questionnaires. The preoperative assessment was done in the prospective cohort only. Of the 75 women who underwent RA-VVF repair, 47 were enrolled, 33 in retrospective, and 14 in a prospective cohort. Overall, 28 (60%) women had urinary complaints with a median UDI-6 total score of 4 (0–100) and IIQ-7 score (0–23) in 5 (10%) women. However, UDS (15 women) showed no DO with cystometric capacity (352 ± 98.12) ml and normal compliance in 14 (93%) women. Mean BOOI and DCI were 11.90 ± 7.01 and 44.25 ± 8.60 respectively, with PdetQmax ranging from 17 to 44. None had difficulty in voiding (Qmax 13.85 ± 4.90). Twenty (43%) women were sexually active, and 2 had sexual dysfunction (FSFI score < 26.55). Quality of life was "good" to "very good" in all domains (score > 90) except for the social domain. The prospective cohort showed significant improvement in UDI-6 score (p < 0.05), IIQ-7 score (p < 0.05), and quality of life (p < 0.05) postoperatively. RA-VVF repair results in minimal voiding dysfunction and significant improvement in overall quality of life. For sexual dysfunction assessment, a longer follow-up is required. [ABSTRACT FROM AUTHOR]

Aim: The voiding diary (VD) yields crucial insights into voiding volumes (VV), voiding frequency (VF), and management habits in children with lower urinary tract (LUT) dysfunction. It is recommended to be conducted for a minimum of 2 days. Nevertheless, certain studies have indicated similarities in voided volumes between days in a three-day VD. This study aims to compare VV and VF values across days based on bladder capacity and symptom scores. Materials and Methods: Children who applied to the pediatric urology clinic due to LUT symptoms between 2022 and 2023 were included in the study. Retrospective evaluation was conducted on the records. Children with neurological deficits and incomplete data were excluded from the study. All children were assessed following the guidelines of ICCS and EUA and underwent a 3-day voiding diary. Mean VV and VF values of the whole group for each day were compared and subgroup analyzes were performed in terms of gender, Voiding Dysfunction Symptom Score (VDSS), bladder capacity (BC), and diagnoses. Results: A total of 109 (53 girls (48.6%), 56 boys (51.4%)) children with a median age of 8 (3-17) were included in the study. 77 (70.6%) children were diagnosed with overactive bladder, 8 (7.4%) with dysfunctional voiding, and 24 (22%) with monosymptomatic enuresis nocturne. The mean VVs between days were similar in the whole group (p = 0.759). Moreover, the mean VV of the first day was similar to the average of both the first two days and the three days (p = 0.021, p = 0.490). Also, the maximum and minimum VVs were similar between days (p = 0.942, p = 0.160, respectively). In subgroup analyses based on gender, bladder capacity, and symptom score, mean VV was also found to be similar. VF values were found to be significantly different between days. There was also a difference between VF values in children with VDSS > 8.5 (p = 0.012) and BC/EBC (%) > 65 (p = 0.030). In subgroup analysis for diagnoses, mean and maximum VV and VF were similar between the groups, except for VF (p = 0.026) in OAB. Conclusion: While the voided volumes of children with non-neurogenic LUT dysfunctions appear to be consistent across the days of the VD, variations in VF might arise, especially among children with a VDSS of > 8.5 and normal bladder capacity. As a result, we believe that using a VD spanning at least two days could enhance diagnostic accuracy and help prevent unnecessary treatment.

IntroductionTreating pediatric voiding dysfunction involves behavioral changes that require significant time or medications that are often avoided or discontinued due to side effects. Using parasacral transcutaneous electrical nerve stimulation (PTENS) has shown to have reasonable efficacy, but the safety and feasibility of its off-label use for pediatric voiding dysfunction are not well-established. Concerns have also been raised over treatment adherence. In-home therapy might improve adherence compared with office-based therapy; however, no studies have evaluated in-home feasibility to date. This study aims to assess the safety and feasibility of off-label use of PTENS for pediatric voiding dysfunction.Materials and methodsA single-institution prospective, randomized controlled study was conducted from March 2019 to March 2020. Participants aged 6–18 years diagnosed with voiding dysfunction, overactive bladder, or urinary incontinence were eligible for the study. Those with known neurologic disorders, implanted electrical devices, anatomic lower urinary tract abnormality, and recurrent urinary tract infections and those taking bladder medications were excluded. Children with primary monosymptomatic nocturnal enuresis were also excluded due to previous work suggesting a lack of efficacy. Participants were randomly assigned to receive 12 weeks of urotherapy alone (control) or urotherapy plus at-home PTENS treatment. Families were contacted weekly to assess for adverse events (AEs) and treatment adherence. The primary and secondary outcomes were safety, defined as the absence of AEs and treatment adherence, respectively.ResultsA total of 30 eligible participants were divided into two groups, with 15 participants in each arm. The median age was 9.4 years (interquartile range: 7.7–10.6). In total, 60% were male. Baseline demographics and urotherapy compliance were similar between the two groups. With PTENS use, two AEs were reported, including mild pruritus at the pad site and discomfort when removing pads, while no AEs were noted in the control group. In total, 60% of patients completed three 30-min sessions per week, and all participants were able to complete treatment sessions for at least 10 weeks, involving 30 min of PTENS treatment each time.ConclusionThis randomized controlled study confirms that at-home use of PTENS is feasible with reasonable treatment adherence and minimal AEs. Future collaborative, multi-institutional studies may better determine the efficacy of this treatment modality.

Objective: To create a reference curve for postvoid residual volume (PVRV) in asymptomatic postpartum women who are at low risk of developing postpartum urinary retention (PUR), a well‐known complication in the immediate postpartum period. Methods: This is a prospective observational study measuring PVRV after uncomplicated vaginal delivery. PVRV was assessed by transabdominal ultrasound using a portable ultrasound scanner within the first 26 h after delivery (PVRV 1) and on the day of discharge (day 2 or 3 postpartum) (PVRV 2). A PVRV of 150 mL or more was defined as the cut‐off value for covert PUR. Results: The prevalence of covert PUR was 7.1%. Primiparity, duration of second stage, and obstetric injury were correlated with higher PVRV 1. The median PVRV 1 was 21 mL and PVRV 2 was 11 mL. The subgroup of nulliparous women had a significantly higher PVRV 1 compared with multiparous women. At discharge, the majority (99.1%) of women had a PVRV of less than 150 mL. Conclusion: Asymptomatic women were at low risk of developing PUR. However, women with a prolonged second stage may benefit from a routine postpartum assessment. Our results allow for a better understanding of PVRV in the early postpartum period. Synopsis: Postpartum urinary retention is a rare finding in asymptomatic women following an uncomplicated vaginal delivery. Assessment of postvoid residual volumes facilitates diagnosis and early intervention. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: Female voiding dysfunction is often due to bladder outlet obstruction (BOO). We investigated pelvic floor muscle training (PFMT) effectiveness in women with functional BOO. Methods: This is a prospective study recruiting 63 women functionally obstructed, over 18yo, maximum flow rate (Qmax) less than 12 ml/sec, naïve of voiding treatment. Exclusion criteria were anatomical BOO, neurological condition, pelvic intervention, psychiatric or anticholinergic medication, diabetes mellitus and affected upper urinary tract. At baseline, women underwent uroflow, post void residual (PVR) measurement, cystoscopy, cystogram and urodynamic study (UDS) with pelvic electromyography (EMG). Blaivas-Groutz nomogram has been used to define obstruction. After diagnosis, patients underwent six-month PFMT. Re-evaluation was offered four weeks after end of treatment. Data were analyzed with SPSSv22.0. Results: 63 women were recruited and 48 finally included. At baseline, 20 reported 3 urinary tract infections (UTIs) during last year, and 12 had one episode of urine retention. Median Qmax was 7.5 ml/sec and median PVR 110 ml. 40 women were obstructed. 16 (40%) had mild, 16 (40%) moderate and 8 (20%) severe obstruction. All subjects had an overactive pelvic floor on EMG. Obstructed women were re-evaluated. Median Qmax was 8.5 ml/sec, close to baseline (p = 0.16). Median PVR was 65 ml, reduced to baseline (p = 0.02). 33 (82.5%) remained obstructed, 22 (66.67%) with mild, 8 (24.24%) moderate and 3 (9.09%) severe obstruction. 7 (17.5%) were non-obstructed. 4 patients reported one UTI episode with no cases of retention. Conclusions: A 6 month PFMT reduced UTIs and PVR in women with functional BOO. Additionally, most patients had a de-escalation to milder obstruction. [ABSTRACT FROM AUTHOR]

Purpose: This study established the prognostic significance of the uroflowmetry flow curve shape in the presence of voiding dysfunction following transvaginal mesh surgery. Methods: This is a retrospective study of 439 symptomatic cystocele patients who underwent anterior wall repair with transvaginal mesh surgery. Uroflowmetry and postvoid residual were used to evaluate voiding function both preoperatively and 12 months postoperatively. The patients were divided into two groups: those with and without postoperative voiding dysfunction, and the predictors of postoperative voiding dysfunction were analyzed. The shape of the urine flow curve was analyzed for its influence on the presence of postoperative voiding dysfunction. Results: Thirty‐five participants were in the voiding dysfunction group, while 404 were in the nonvoiding dysfunction group. Multivariate analysis was conducted by adding an interrupted‐shaped curve to age, Qmax, and postvoid residual, which showed significant differences in univariate analysis, found that age 68 years or older (odds ratio [OR]: 7.68, 95%CI 1.02–58, p = 0.048), postvoid residual ≥110 mL (OR: 2.8, 95%CI 1.25–6.29, p = 0.013) and interrupted‐shaped curve (OR: 2.47, 95%CI 1.07–5.69, p = 0.034) were discovered to be independent risk factors for the presence of voiding dysfunction after transvaginal mesh surgery. Conclusions: Following transvaginal mesh surgery for cystocele, three variables were found to be predictive of voiding dysfunction: the old age, excessive postvoid residual, and an interrupted‐shaped flow curve. The uroflowmetry flow curve shape has the potential to be a new predictor of postoperative voiding dysfunction. [ABSTRACT FROM AUTHOR]

Objective: To demonstrate the outcome of transvaginal urethrolysis as a treatment option for women with recurrent cystitis, which could be caused from voiding problems. In the case of a failure of non-invasive treatment, the surgical procedure to decrease outlet resistance may have a role. Materials and Methods: Between January 2016 and December 2020, women with recurrent cystitis who underwent urethrolysis at Siriraj Hospital were retrospectively reviewed. Only women who were followed-up for more than 6 months were analyzed. Cure was defined by no clinical symptoms of cystitis, no pyuria on urine analysis, and/or negative urine culture during the follow-up period. Results: In total, 52 women underwent transvaginal urethrolysis. The overall cure rate was observed 53.9% (28 cases) at a median follow-up time of 11.9 (6--59) months. Eighteen of the 44 cases (40.9%) who underwent a video urodynamics study showed bladder outlet obstruction, defined as a Solomon--Greenwell bladder outlet obstruction index of more than 5. None of the characteristics or urodynamics parameters showed statistically significant differences between the cure and failure groups. Postoperative urinary incontinence was reported in 14 cases (26.9%) but showed no statistical difference between the cure and failure group (p = 0.748). Conclusion: Bladder outlet obstruction is a common cause of recurrent cystitis. Transvaginal urethrolysis may have a role as treatment for women with recurrent cystitis from voiding dysfunction who have failed non- and less-invasive treatments. Here, the overall cure rate was 53.8%. A factor associated with the cure rate could not be demonstrated in this study. [ABSTRACT FROM AUTHOR]

Abstract Background We aimed to determine whether different urination positions had significant impact on the parameters of uroflowmetry performed by healthy individuals and children with voiding dysfunction. Methods The study was conducted with a prospective and comparative design. Children between 5 and 15 years of age who met the inclusion–exclusion criteria of the study were enrolled. Children in the study were divided into two groups. Participants whose voiding dysfunction symptom score was ≥ 9 points were classified in group 1 and the remaining individuals were classified in group 2. Girls urinated in two different positions as sitting and squatting while boys urinated in three different positions as sitting, squatting and standing. Also, habitual urination position was asked and recorded for each individual participated in the study. Uroflowmetry parameters were compared for different urination positions in two groups separately and a p value of ≤ .05 was accepted for statistical significance. Results Voided volume, maximum flow rate (Qmax), time to reach Qmax, urination time and postvoid residual volume measured by abdominal ultrasound were recorded in every participant for each urination position in both groups. In group 1, girls with voiding dysfunction presented a significantly higher postvoid residual volume in squatting position compared to sitting position (the p value = 0.02). In group 2, healthy boys presented a significantly higher Qmax in standing position compared to sitting and squatting positions (the p value = 0.01). All participants provided a better uroflowmetry pattern in their habitual urination positions. Conclusion Urination position may affect uroflowmetry results; however, its impact on lower urinary tract function requires further research.
