Efectividad del entrenamiento muscular pélvico temprano en la fuerza de suelo pélvico, síntomas de incontinencia urinaria, función sexual y calidad de vida en pacientes posprostatectomía radical: revisión sistemática de ensayos clínicos aleatorizados / Effectiveness of early pelvic muscle training on pelvic floor strength, urinary incontinence symptoms, sexual function, and quality of life in post-radical prostatectomy patients: Systematic review of randomized clinical trials

Este estudio tuvo como objetivo evaluar la efectividad del entrenamiento muscular pélvico temprano para reducir los síntomas de incontinencia urinaria, mejorar la calidad de vida, función sexual y aumentar la fuerza de suelo pélvico en pacientes posprostatectomía radical. Se realizó una búsqueda en 8 bases de datos hasta el 26 de octubre de 2022, se evaluó la calidad metodológica y el riesgo de sesgo de 14 estudios incluidos (n=1236), se calculó la evidencia y el metaanálisis. El entrenamiento redujo significativamente los síntomas de incontinencia urinaria en comparación con un grupo control (DME=−2,80; IC 95%=−5,21 a −0,39; p=0,02), con heterogeneidad significativa (I2=83%; p=<0,0001) y evidencia moderada. Además, presentó evidencia moderada para mejorar la calidad de vida, y muy baja para mejorar la función sexual y fuerza de suelo pélvico. Estos resultados deben ser observados con precaución debido a la heterogeneidad significativa de los estudios analizados. (AU)

This study aimed to evaluate the effectiveness of early pelvic muscle training in reducing urinary incontinence symptoms, improving quality of life, sexual function, and increasing pelvic floor strength in post-radical prostatectomy patients. A search was carried out in 8 databases until October 26, 2022, the methodological quality and the risk of bias of 14 included studies (n=1236) were evaluated, moreover, the evidence and the meta-analysis were calculated. The intervention significantly reduced urinary incontinence symptoms compared to a control group (SMD=−2.80, 95% CI=−5.21 to −0.39, P=.02), with significant heterogeneity (I2=83%; P=<.0001) and moderate evidence. In addition, it presented moderate evidence to improve quality of life, and very low evidence to improve sexual function and pelvic floor strength. These results should be viewed with caution due to the significant heterogeneity of the studies analysed. (AU)

Care Needs of Older Adults With Urinary Incontinence: A Cross-Sectional Study.

PURPOSE: To explore care requirements of older adults with urinary incontinence (UI) and contributing factors. METHOD: This cross-sectional study used the Older Adults Urinary Incontinence Care Needs Inventory to survey participants with UI in three large-scale tertiary hospitals located in Guangzhou City, China, from January 2023 to November 2023. Statistical analyses, including analysis of variance, t tests, correlation analyses, and linear regression models, were conducted to assess factors influencing participants' care needs. RESULTS: A total of 530 older adults with UI participated in the survey and mean standardized score for overall care needs was 78.65 (SD = 5.01), with mean scores for each dimension ranging from 70.88 (SD = 10.55) for social participation needs to 82.45 (SD = 7.11) for health education needs. Factors that were found to influence incontinence care needs in older adults included age, literacy level, number of leaks, and type of disease (F = 37.07, adjusted R2 = 0.290, p < 0.001). CONCLUSION: Comprehensive care for older adults with UI, encompassing physiological, psychological, and social aspects, is crucial. It is essential to tailor care to individual needs and characteristics, taking into account factors, such as age and education, to ensure effective care.

Incontinence-associated dermatitis in older adults in residential care settings: a point prevalence study.

Incontinence-associated dermatitis (IAD) is a skin inflammation caused by contact with urine or faeces or both. It has a negative effect on the patient's quality of life and is indicative of the care provided. However, globally there is a lack of empirical data on the prevalence of IAD. AIM: To identify, for the first time, the proportion of older adults in extended care settings in Ireland affected by IAD. DESIGN: Cross-sectional, multisite, point prevalence survey, across three community extended care settings for older people in Ireland. METHODS: Two clinical nurse specialists, using the Scottish Excoriation and Moisture Related Skin Damage Tool, identified the presence of IAD through clinical observation and visual skin inspection. IAD prevalence was calculated for the total population and incontinent population sets using percentages and confidence intervals (CI). RESULTS: The prevalence of incontinence was 86.4% (n=165), a significantly higher proportion were female (P=0.003). The point prevalence of IAD across the total population and incontinent population was 11.5% (22/191; 95% CI, 7.4-19.9%) and 13.3% (22/164; 95% CI, 8.5-19.5%), respectively. Being incontinent was associated with being female, more dependent (Barthel), having possible cognitive impairment, poorer mobility (Braden and Waterlow) and a high risk of pressure ulcers (Waterlow). A logistic regression analysis found no predictor variables for IAD among the variables that met the cut-off point for this analysis. CONCLUSIONS: The study provides the first point prevalence empirical data on the occurrence of IAD in Ireland. It can inform decision-making on future planning and budgeting of new quality improvement projects and act as a benchmark for ongoing auditing of IAD.

Comparison of perioperative and functional outcomes of single-incision versus standard multi-incision robot-assisted laparoscopic radical prostatectomy: a prospective, controlled, nonrandomized trial.

To compare perioperative and functional outcomes between improved (port-free) single-site robot-assisted laparoscopic radical prostatectomy (pf-ssRARP) and standard multi-port robot-assisted radical prostatectomy (MPRARP). A total of 372 consecutive patients underwent RARAP using the da Vinci Si® robotic surgical system. Group I (n = 210) included patients undergoing pf-ssRARP and Group II (n = 162) included patients undergoing MPRARP. Demographics and perioperative data including postoperative recovery outcomes were recorded and compared between the two groups. Overall mean operative time was significantly shorter with the pf-ssRARP compared to the MPRARP (p < 0.05). The length of hospitalization after the pf-ssRARP was shorter (p < 0.05). In Group I, the positive surgical margin rate was 15.2%; while in Group II, the positive margin rate was 33.3% (p < 0.05). The rate of instant urinary continence was significantly higher in Group I than in Group II (p < 0.05). The percentage of urinary continence was higher in the pf-ssRARP than in the MPRARP, at 6 months post-surgery (p < 0.05) and 9 months post-surgery (p < 0.05). There was no significant difference in the proportion of erectile function in the pf-ssRARP and MPRARP groups at the time of reaching the endpoint of this study (p > 0.05). The two groups were comparable in terms of total hospitalization costs (p < 0.05). The improved (port-free) single-site robot-assisted laparoscopic radical prostatectomy is a practical and easy technique to implement in clinical practice. Extraperitoneal implementation of the modified technique requires only a small incision, no special PORT, no additional auxiliary foramen creation, increased postoperative aesthetics and reduced hospitalization costs, and a high percentage of early postoperative urinary control recovery.

Real world propensity score matched analysis evaluating the influence of en-bloc vs. non en-bloc techniques, energy and instrumentation on enucleation outcomes for large and very large prostates.

PURPOSE: The primary aim of the study was to evaluate if en-bloc vs. non en-bloc made a difference to intra-, peri- and post-operative surgical outcomes of anatomical endoscopic enucleation (AEEP) in large (> 80 cc) and very large prostates (> 200 cc). The secondary aim was to determine the influence of energy and instruments used. METHODS: Data of patients with > 80 cc prostate who underwent surgery between 2019 and 2022 were obtained from 16 surgeons across 13 centres in 9 countries. Propensity score matching (PSM) was used to reduce confounding. Logistic regression was performed to evaluate factors associated with postoperative urinary incontinence (UI). RESULTS: 2512 patients were included with 991 patients undergoing en-bloc and 1521 patients undergoing non-en-bloc. PSM resulted in 481 patients in both groups. Total operation time was longer in the en-bloc group (p < 0.001), enucleation time was longer in the non en-bloc group (p < 0.001) but morcellation times were similar (p = 0.054). Overall, 30 day complication rate was higher in the non en-bloc group (16.4% vs. 11.4%; p = 0.032). Rate of late complications (> 30 days) was similar (2.3% vs. 2.5%; p > 0.99). There were no differences in rates of UI between the two groups. Multivariate analysis revealed that age, Qmax, pre-operative, post-void residual urine (PVRU) and total operative time were predictors of UI. CONCLUSIONS: In experienced hands, AEEP in large prostates by the en-bloc technique yields a lower rate of complication and a slightly shorter operative time compared to the non en-bloc approach. However, it does not have an effect on rates of post-operative UI.

Incontinence and homelessness.

The fundamental principles of why specific people become homeless, can be grounded in a simple rationale or founded within sophisticated reasoning. For instance, people who suffer from substance abuse, addiction, alcohol, gambling, have mental health concerns or financial difficulties may be susceptible to homelessness. It is also identified that persons who experienced violence in their childhood or abuse by a partner are at a higher risk of becoming homeless. Homelessness knows no ethnic, cultural, religious or gender boundaries, and can impact all individuals' health and well-being. A health problem and worldwide phenomenon that affects all cohorts of the population, including the homeless, is urinary incontinence. The aim of this article is to increase the awareness of incontinence and highlight the impact it has on the lives of people that experience homelessness.

Incontinence in people living with dementia.

Dementia and incontinence are both prevalent in older age; yet, neither are an inevitable or normal part of ageing. It has been recognised that there is a skills and knowledge gap in professionals assessing and managing incontinence for people living with dementia. All too often, assumptions are made that incontinence is a symptom of dementia and that nothing can be done if a person living with dementia experiences episodes of incontinence. While dementia may impact on a person's ability to remain continent, it may not be the sole cause, and there may be treatments and strategies that can reduce the incidence in those affected. Therefore, a person-centred continence assessment should be undertaken to promote continence and reduce the impact of incontinence for people living with dementia and those who care for them. This paper will highlight some of the issues that are important for health and social care professionals to explore and identify, assess and manage incontinence to improve outcomes for families affected by dementia.

Guidance for the provision of absorbent products for adult incontinence.

The Association for Continence Professionals first published their guidance for the provision of absorbent products for adult incontinence in 2017. This consensus document is targeted towards commissioning leads, NHS Trust Boards, Bladder and Bowel leads, among others, and has been updated over the years to ensure that all adults who suffer with continence issues undergo a comprehensive assessment and have access to an equitable service. This article provides an overview of the latest guidelines which were published in February 2023.

Is the varying management of incontinence-associated dermatitis due to a lack of understanding of etiology?

Incontinence-associated dermatitis, previously and sometimes still referred to as moisture lesions or moisture damage, is a commonly seen contact dermatitis that is a reactive response of the skin to chronic contact to urine and faecal matter. Understanding the etiology is fundamental to creating a skin care plan and successfully prevention. Systemic reviews and studies have shown that the continued variability in management results from a combination of knowledge base, observation, diagnosis, and product selection. This article aims to improve clinicians' understanding of incontinence-associated dermatitis and its management.

Penile urinary sheaths: a continence management system for men.

Urinary leakage is prevalent in men. To contain and manage this leakage, men are often advised about urinary devices. However, sometimes this advice does not include penile sheaths. Penile sheaths are a good way of managing urinary leakage if an individual is suitable for sheaths. This article will explore this suitability, advantages to using a sheath, reasons why sheaths may not be suitable, and will discuss optimum fitting to ensure the sheath is a secure drainage device.

Pudendal nerve neurolysis outcomes for urogenital and rectal disorders in patients suffering from pudendal nerve entrapment: A systematic review.

PURPOSE: Pudendal neuropathy is an uncommon condition that exhibits several symptoms depending on the site of nerve entrapment. This study aims to evaluate the efficacy of pudendal nerve neurolysis (PNN) in improving lower urinary tract symptoms, anal and/or urinary incontinence, and sexual dysfunctions. MATERIALS AND METHODS: A systematic literature search was performed on 20 May 2023 using Scopus, PubMed, and Embase. Only English and adult papers were included. Meeting abstracts and preclinical studies were excluded. RESULTS: Twenty-one papers were accepted, revealing significant findings in the field. The study identified four primary sites of pudendal nerve entrapment (PNE), with the most prevalent location likely being at the level of the Alcock canal. Voiding symptoms are commonly exhibited in patients with PNE. PNN improved both urgency and voiding symptoms, and urinary and anal incontinence but is less effective in cases of long-standing entrapment. Regarding sexual function, the recovery of the somatic afferent pathway results in an improvement in erectile function early after neurolysis. Complete relief of persistent genital arousal disorder occurs in women, although bilateral PNN is necessary to achieve the efficacy. PNN is associated with low-grade complications. CONCLUSIONS: PNN emerges as a viable option for addressing urinary symptoms, fecal incontinence, erectile dysfunction, and female sexual arousal in patients suffering from PNE with minimal postoperative morbidity.

Enhancing continence post holmium laser enucleation of the prostate: assessment of novel technique through randomized clinical trial.

BACKGROUND: Transient urinary incontinence (UI) is distressing event following holmium laser enucleation of the prostate (HoLEP). Novel technique namely, veil sparing HoLEP (VS-HoLEP), was proposed to improve early continence outcome. In this trial (NCT03494049), VS-HoLEP was compared to standard HoLEP (St-HoLEP). METHODS: VS-HoLEP entails early apical separation with sparing of ventral apical mucosal veil proximal to the verumontanum. Eligible symptomatic BPH patients were randomly allocated to St-HoLEP (91) and VS-HoLEP (89). The primary outcome was UI as depicted by one-hour pad test at one month postoperatively. Other outcome measures include all perioperative parameters, complications, and urinary outcome measures at different follow-up points. RESULTS: Median preoperative prostate size was 138 (50:282) and 128 (50:228) mL in St-HoLEP and VS-HoLEP groups respectively. At one month the number of patients with positive one-hour pad test was 21 (23.1%) and 10 (11.4%) in St-HoLEP and VS-HoLEP groups respectively (P 0.047). The difference was significantly in favor of VS-HoLEP considering the number of patients reporting UI, the number of patients with positive one-hour pad test as well as the grade of UI reported at one and 4 months. The difference was not statistically significant at 12 months. The median time to patients' reported continence was 8 (1-52) and 1.5 (1-52) weeks in St-HoLEP and VS-HoLEP groups respectively (P≤0.005). The technique independently predicted positive one-hour pad test at one and four months respectively. At twelve months presence of DM (diabetes mellitus) and more percent PSA reduction independently predicted positive one-hour pad test. CONCLUSIONS: Veil sparing HoLEP enhances significantly early postoperative urine continence both subjectively and objectively. Optimization of the surgical technique could cut short the number of leaking patients and reduce the degree as well as the duration of transient postoperative urine leak.

Examining workplace behaviors in adult women with urinary incontinence: A pilot study.

BACKGROUND: Urinary incontinence is a growing issue among adult women globally. Limited data exist examining the impact of occupational, environmental, and behavioral factors on urinary incontinence. OBJECTIVE: This quantitative, cross-sectional pilot study examined the workplace behaviors of adult women experiencing urinary incontinence. It was hypothesized that specific jobs and work environments would be associated with increased urinary incontinence and urgency based on identified behaviors and work-related conditions. DESIGN: This study is a quantitative, cross-sectional survey. METHODS: Adult women (18 years and older) with a history of urinary incontinence were recruited from August 2022 to February 2023 to complete a one-time survey consisting of multiple-choice and short answer questions identifying specific workplace behaviors and symptoms of urinary incontinence. Descriptive statistics and data categorization were used to observe outcomes and examine relationships between urinary incontinence and particular professions. RESULTS: Urinary incontinence and urgency-related symptoms affected healthcare and business professionals at a higher prevalence. The most commonly reported behaviors across all professions consisted of withholding urine and utilizing absorbance products. CONCLUSION: The results of this study will help guide women's health practitioners in exploring current workplace behaviors that may contribute to urinary incontinence in adult women. With this knowledge, practitioners can provide meaningful education to employers and employees to prioritize toileting behaviors in the workplace.

Symptomatology and knowledge regarding pelvic floor dysfunctions and influence of gender stereotypes in female athletes.

Pelvic floor dysfunctions (PFD) are highly prevalent among females who do athletics, a sport requiring jumping, strength, and running. Although educational approaches are useful options, the educational need for this particular population remains unknown. The objective of the present study was to describe the level of knowledge regarding PFD and its relationship with symptomatology and gender stereotypes in female athletes in Spain. A total of 255 female athletes completed an anonymous online survey to explore their knowledge regarding urinary incontinence (UI), pelvic organ prolapse (POP), anal incontinence (AI), and sexual dysfunction (SexD), as well as their PFD symptoms and gender stereotyped beliefs related to sport. Educational level and sports characteristics (training volume, experience, and athletic modality) were also explored. Participants demonstrated a low level of knowledge in terms of POP (52.5%), AI (64.0%), and SexD (40%), but not for UI (70.8%). The proportion of PFD complaints was 63.5% for dyspareunia, 51.8% for urine leakage, 42.4% for pelvic pain, 17.3% for AI, and 9.0% for POP, with no associations with knowledge (p > 0.05). Lower knowledge about UI and SexD was related to greater gender stereotypes (p < 0.05) and rejection of professional healthcare (p = 0.010). As a conclusion, the level of knowledge about PFD was low in female athletes who train and compete in athletics in Spain, mainly with regard to sexual dysfunction. Although 63.5% of athletes had dyspareunia and 51.8% urinary leakages, symptomatology was not associated with level of knowledge. However, a lower level of knowledge was associated with more stereotyped beliefs and rejection of professional healthcare for PFD. These findings confirm the need to design appropriate educational interventions to disseminate information on all the types of PFD, particularly sexual contents. The potential influence of gender stereotypes makes it appropriate to include the gender perspective in these interventions.

Functional Status in Relation to Common Geriatric Syndromes and Sociodemographic Variables - A Step Forward Towards Healthy Aging.

Purpose: Geriatric syndromes (GS) are prevalent in the older population, with an impact on morbidity and disability. This study aimed to investigate the prevalence of functional dependence and ten GS in community older adults and to examine the different associations between these syndromes and sociodemographic variables and their impact on functional dependence. Patients and Methods: A cross-sectional study of 342 outpatients seen at the geriatric clinic in the period 2015-2023. Results: The mean age was 75±7.4. One-third had functional dependence and 96.2% had at least one GS. The mean number of GS was 3.11±1.74, ranging from 2.56±1.67 in the 60s to 3.55±1.70 in octogenarians. The most common GS found were polypharmacy (79.5%), musculoskeletal pain (49.7%), and Major Neurocognitive Disorder (MND) (32.7%). Polypharmacy was significantly associated with female sex and chronic pain, whereas sensory impairment was associated with male sex. MND, dizziness, and urinary incontinence were the only GS that significantly predicted functional dependence and were typically associated with increasing age. Conclusion: Functional dependence increases as individuals age, paralleled by increases in MND, urinary incontinence, dizziness, sensory impairment, and constipation. Notably, only MND, incontinence, depression, and dizziness were significant predictors of functional dependence. Consequently, it is imperative to screen older adults presenting with these syndromes for early signs of functional decline to optimize their function and avert subsequent dependence, morbidity, and mortality.

The association between non-alcoholic fatty liver disease and urinary incontinence among adult females in the United States.

BACKGROUND AND OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) and urinary incontinence (UI) are both highly prevalent and age-related diseases. Nevertheless, the link between NAFLD and UI is unclear. Hence, the study was designed to evaluate the association between the NAFLD and UI (including UI types) in a nationally representative sample of United States (US) female adults. METHODS: We conducted this study used data from U.S. female adults in the National Health and Nutrition Examination Survey (NHANES) 2017-March 2020 (pre-pandemic) cycles. The diagnosis of NAFLD is based on Vibration controlled transient elastography (VCTE) and absence of know liver diseases and significant alcohol consumption. The diagnosis and types of UI were assessment using a self-report questionnaire. Multivariable logistic regression models were used to analyze the association between NALFD and UI. Stratified analyses based on age, obesity, race, educational level, married status, PIR, and smoking status were conducted. RESULTS: Of the 2149 participants, the mean (95% CI) age was 53.9 (52.7-55.0), 686 (61.1%) were Non-Hispanic White. UI was significantly more common in participants with NAFLD [490 (64.7%)] than those without NAFLD [552 (44.9%)]. Adjusted for age, race/ethnicity, marital status, educational level, family poverty income ratio (PIR) status, alanine aminotransferase (ALT), aspartate aminotransferase (AST), smoking status, obesity, type 2 diabetes mellitus (T2DM), hypertension and insulin resistance (IR) in a multivariable logistic regression model, NALFD were associated with UI [OR: 1.93, 95%CI 1.23-3.02, P = 0.01] and urge UI [OR: 1.55, 95%CI 1.03-2.33, P = 0.03], while patients with NAFLD did not show an increased odds in stress UI and mixed UI when compared with those without NAFLD subject (P > 0.05). In the subgroup analyses, NAFLD remained significantly associated with UI, particularly among those participants without obesity (OR: 2.69, 95% CI 1.84-4.00) and aged ≥ 60 years (OR: 2.20, 95% CI 1.38-3.51). CONCLUSIONS: Among US female adults, NAFLD has a strong positive correlation with UI. Given that NAFLD is a modifiable disease, these results may help clinicians to target female patients with NAFLD for treatments and interventions that may help prevent the occurrence of UI and reduce the symptoms of UI.

The association between urinary incontinence and suicidal ideation: Findings from the National Health and Nutrition Examination Survey.

BACKGROUND: Urinary incontinence (UI) might be linked to suicidal ideation, but we do not yet have all the relevant details. This study aimed to dig deeper into the connection between UI and suicidal ideation using data from the National Health and Nutrition Examination Survey (NHANES). METHODS: We examined 31,891 participants aged ≥ 20 years from NHANES 2005-2018 who provided complete information. We used standardized surveys to check for UI and signs of suicidal ideation. To better understand this relationship, we used statistical tools such as multivariable logistic regression, subgroup analysis, and sensitivity analyses. RESULTS: Among the 31,891 participants, 28.9% reported UI and 10.7% reported suicidal ideation. Those with UI exhibited a significantly greater incidence of suicidal ideation (15.5%) than did those without UI (8.8%, P < 0.001). After adjusting for various factors, including age, sex, marital status, socioeconomic status, educational level, lifestyle factors, and chronic comorbidities, UI remained significantly associated with suicidal ideation (OR:1.54, 95% CI = 1.39-1.7, P < 0.001). Among all types of UI, MUI participants were more likely to experience suicidal ideation. Compared with no UI, higher odds of suicidal ideation suffered from MUI (OR:2.11, 95%CI:1.83-2.44, P < 0.001), SUI (OR:1.4, 95%CI:1.19-1.65, P < 0.001), UUI(OR:1.37,95%CI:1.16-1.62, P < 0.001) after full adjustment. With the exception of individuals living with a partner, the remaining subgroups exhibited a positive correlation between urinary incontinence and suicidal ideation, considering that factors such as age, sex, and prevalent comorbidities such as hypertension, depression, and diabetes did not reveal any statistically significant interactions (all P > 0.05). Sensitivity analyses, incorporating imputed missing covariates, did not substantially alter the results (OR: 1.53, 95% CI: 1.4-1.68, P < 0.001). CONCLUSION: Urinary incontinence may correlate with increased suicidal ideation risk, priority screening for suicidal ideation and timely intervention are essential for individuals with urinary incontinence, but prospective studies are needed to verify the results.

4-Aminopyridine treatment for nerve injury resulting from radical retro-pubic prostatectomy: a single-center double-blind, randomized, placebo-controlled study.

BACKGROUND: Prostate cancer (PCa) is the most common non-cutaneous malignancy in men and leads to the second most common cause of cancer related mortality in men. Early detection of PCa allows for a potentially curative intervention. Most men will live over a decade from the time of their PCa diagnosis. Thus, treatments must balance curative interventions with their impact on quality of life. Radical prostatectomy (RP) is one such potentially curative intervention but often leads to erectile dysfunction (ED) and urinary incontinence (UI). Approximately 90,000 RPs are performed each year in the USA. Post-operative ED and UI is thought to occur in part from traumatic peripheral nerve injury (TPNI) to the neurovascular bundles that surround the prostate. Thus, patients undergoing RP may be a population that would benefit from clinical studies that look at TPNI. METHODS: The study is a single-institution, double-blinded placebo-controlled, randomized clinical trial in which patients immediately post-RP receive either 4-aminopyrdine (4AP) or placebo in a 1:1 fashion. The primary outcome is evaluation of the efficacy of 4AP in accelerating the early return of baseline erectile and urinary function post-radical prostatectomy. DISCUSSION: This study is critical as it could reduce the morbidity associated with RP, a commonly performed operation, and identify a patient population that may greatly benefit into further TPNI research. TRIAL REGISTRATION: ClinicalTrials.gov NCT03701581. Prospectively registered on October 10, 2018.

Membranous urethral length is the single independent predictor of urinary continence recovery at 12 months following Retzius-sparing robot-assisted radical prostatectomy.

The influence of anatomical parameters on urinary continence (UC) after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) remains uncharted. Our objective was to evaluate their association with UC at 3, 6 and 12 months post-operatively. Data from patients who underwent RS-RARP were prospectively collected. Continence was defined as no pad use. Anatomic variables were measured on preoperative magnetic resonance imaging (MRI). Regression analyses were performed to identify predictors of UC at each time point. We included 158 patients with a median age of 60 years, most of whom had a localized tumor (≤ cT2). On multivariate analyses, at 3 months post-surgery, urinary incontinence (UI) rises with age, odds ratio (OR) 1.07 [95% confidence interval (CI) 1.004-1.142] and with prostate volume (PV), OR 1.029 (95% CI 1.006-1.052); it reduces with longer membranous urethral length (MUL), OR 0.875 (95% CI 0.780-0.983) and with higher membranous urethral volume (MUV), OR 0.299 (95% CI 0.121-0.737). At 6 months, UI rises with PV, OR 1.033 (95% CI 1.011-1.056) and decreases with MUV, OR 0.1504 (95% CI 0.050-0.444). Significantly, at 12 months post-surgery, the only predictor of UI is MUL, OR 0.830 (95% CI 0.706-0.975), establishing a threshold associated with a risk of UI of 5% (MUL > 15 mm) in opposition to a risk of 25% (MUL < 10 mm). This single institutional study requires external validation. To our knowledge, this is the first prospective cohort study supporting MUL as the single independent predictor of UC at 12 months post-surgery. By establishing MUL thresholds, we enable precise patient counseling.
