Predictive factors of post-HoLEP incontinence: differences between stress and urgency urinary incontinence.

INTRODUCTION: The analysis of post-HoLEP urinary incontinence (UI) has traditionally focused on stress UI. Our aim is to evaluate the factors associated with stress and urgency UI in the first month after the surgery. METHODS: Data were obtained from patients who underwent HoLEP by the same experienced surgeon. UI was evaluated at one month and at 6 months after the surgery. Three groups were defined: continent patients, patients with pure urgency UI and patients with stress or mixed UI. Preoperative, intraoperative, urodynamic and clinical variables were analyzed and compared between the three groups. RESULTS: In total, 235 subjects were included. One month after the surgery, 156 (66.5%) were continent (group 1), 49 (20.8%) reported pure urgency UI (group 2), and 30 (12.7%) reported some level of stress UI (group 3). In Group 2, the factors associated with urgency UI in the univariate analysis were age, presurgical urgency UI, having diabetes or hypertension. In Group 3, age, prostatic volume, preoperative PSA, time of enucleation, weight of the resection in grams, having an IDC or being diabetic were significant in the univariate analysis. In the multivariate analysis, age predicts both types of UI, while prostatic volume and having an IDC predict stress or mixed UI. CONCLUSION: In the first month post-HoLEP, age is a predictive factor of urgency UI and stress UI. In addition, prostatic volume and the presence of an indwelling urinary catheter are predictive factors of stress UI.

Incidence and risk factors of stress urinary incontinence after laparoscopic hysterectomy.

OBJECTIVE: To observe the long-term effects of total hysterectomy on urinary function, evaluate the effects of preoperative nutritional status, urinary occult infection, and surgical factors on the induction of postoperative stress urinary incontinence (SUI), and explore the incidence and risk factors of SUI. STUDY DESIGN: From January 2017 to December 2017, 164 patients with benign non-prolapsing diseases who underwent a laparoscopic total hysterectomy in the First People's Hospital of Taicang were selected as the analysis objects. The International Incontinence Standard Questionnaire for Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) and Pelvic Floor Impact Questionnaire-short version 20 (PFDI-20) were used for telephone follow-up to subjectively assess the urinary function of patients, collect their medical records, and statistically analyze the number of postoperative SUI cases. Logistic multivariate analysis was used to analyze the influencing factors of postoperative female SUI, presented as adjusted odds ratios with 95% confidence intervals. RESULTS: Only 97 out of 164 patients completed the ICIQ-FLUTS and PFDI-20 questionnaires. Among these participants, 28 patients (28.86%) were diagnosed with SUI (study group), while 69 patients (71.13%) were classified as women without SUI (control group). The age, menopause, parity ≥ 2 times, Body mass index (BMI) ≥ 28 kg/m2, neonatal weight ≥ 4000 g, history of chronic cough, preoperative hemoglobin ≤ 100 g/L, preoperative urine bacteria ≥ 100u/L, preoperative uterine volume ≥ 90 cm3, intraoperative blood loss, and operation time of the study group were compared with those of the control group. The differences were statistically significant (P < 0.05). Further Logistic multivariate analysis showed that menopause, preoperative hemoglobin ≤ 100 g/L, preoperative urine bacteria ≥ 100u/L, uterine volume ≥ 90 cm3, history of chronic cough, BMI ≥ 28 kg/m2 were risk factors for postoperative SUI in patients undergoing hysterectomy (P < 0.05). CONCLUSIONS: Hysterectomy for benign non-prolapse diseases has a long-term potential impact on the urinary system of patients, and the risk of postoperative SUI increases. The main risk factors of SUI are parity, menopausal status, obesity, preoperative nutritional status, and occult infection of the urinary system.

Unilateral levator avulsion increases the risk of de novo stress urinary incontinence after cystocele repair.

INTRODUCTION: Patients without concurrent baseline stress urinary incontinence (SUI) can develop de novo SUI after transvaginal mesh surgery (TVM) for cystocele repair. Surgeons should be aware of de novo SUI risk factors after TVM. METHODS: A total of 1124 women who were underwent TVM surgeries were recruited and assessed for eligibility from January 1, 2012 to April 30, 2021. All data related to patients and surgeries was collected, which included general conditions, clinical examination, surgery records, and follow-up results. Patients were divided into three groups according to follow-up results and data were compared with each group. The relative risk (RR) of de novo SUI with levator avulsion was also calculated. RESULTS: Three hundred thirty-six patients were included in this study. They were divided into no complication group (n = 249), de novo SUI group (n = 68), and other complications group (n = 19). It seemed elder or obese women had a higher risk of de novo SUI after TVM (p < 0.05). In de novo SUI group, incidence of levator avulsion before surgery were higher than the other two groups (p = 0.001). TVM can significantly change a prolapse to point Aa and Ba on POP-Q quantification system (p < 0.05). RR ratios of de novo SUI with unilateral avulsion group is 2.60 (95% confidence interval [CI] 1.39-4.87), and 2.58 (95%CI 0.82-8.15) for bilateral group. CONCLUSION: Unilateral levator avulsion, instead of bilateral levator avulsion, is a risk factor of de novo SUI after cystocele repair surgery.

Impact of childbirth on pelvic floor dysfunction in women who have undergone previous pelvic floor reconstructive surgery: systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: The aim of the study was to perform a systematic review and meta-analysis of the impact of pregnancy and childbirth (vaginal delivery [VD]) or cesarean section (CS) on the recurrence of pelvic floor disorders in women who had previously undergone pelvic floor reconstructive surgery for pelvic organ prolapse (POP) or stress urinary incontinence (SUI), to facilitate future evidence-based counseling. METHODS: PubMed, Cochrane, Embase, BJOG, Scopus, etc. were screened, from 1990 to date. Inclusion criteria included cohort studies, case-control studies, case series, and case reports that reported on the primary outcome measure of the review. Exclusion criteria included studies on surgical procedures whose outcomes are unlikely to be impacted by pregnancy and childbirth or are obsolete. Meta-analysis was performed using Review Manager 5.3. RESULTS: Seven papers on midurethral slings (MUS; 181 women in both VD and CS groups respectively) and three papers on different hysteropexy techniques (47 and 29 women in the VD and CS groups respectively), were included in the meta-analysis. No difference was seen between the two groups regarding the recurrence of SUI in women who had previously undergone MUS surgery (OR: 1.18 [0.66, 2.09]; Z = 0.56; p = 0.58) or the recurrence of POP following hysteropexy using various apical suspension procedures (OR: 1.81 [0.04, 80.65]; Z = 0.31; p = 0.76). There are insufficient data to support meta-analyses for individual MUS sub-types or hysteropexy procedures. CONCLUSION: Current literature does not demonstrate a protective effect of CS in preventing recurrent SUI in women who had undergone MUS surgery for SUI. When hysteropexy is considered irrespective of the apical suspension procedure employed, the incidence of recurrent POP appears similar after CS and VD.

Bladder neck incompetence could be an etiology of overactive bladder syndrome in women with stress urinary incontinence after anti-incontinence surgery: insights from transrectal sonography.

PURPOSE: To investigate the prevalence of bladder neck incompetence (BNI) and the anatomic differences between different types of urinary incontinence (UI) and overactive bladder (OAB) by transrectal sonography, and to investigate these differences among those with stress UI (SUI) or mixed UI (MUI) who exhibited de novo or persistent OAB symptoms following anti-incontinence surgery. METHODS: A retrospective analysis was conducted on a total of 184 patients with SUI, MUI, urge UI (UUI), or OAB dry who underwent transrectal ultrasound between 2017 and 2022. The presence of BNI and urethral incompetence assessed by transrectal ultrasound were recorded in all included patients, and recorded preoperatively and postoperatively among patients with SUI and MUI who underwent anti-incontinence surgery. RESULTS: Among the patients, 91%, 84%, 76%, and 71% exhibited BNI in MUI, SUI, UUI, OAB dry group, respectively. Significantly higher rate of patients with BNI were found in MUI than in OAB dry group. Patients with OAB symptoms after anti-incontinence surgery exhibited significantly higher rates of BNI and urethral incompetence than those who did not have postoperative OAB symptoms. Among MUI patients with preoperative BNI, significantly lower rate of postoperative BNI and urethral incompetence was observed in individuals who had improved OAB symptoms after surgery, compared to those without improvement. CONCLUSION: A higher BNI rate was observed in the MUI group. A significantly higher BNI rate was observed in women with OAB symptoms after anti-incontinence surgery. Patients with MUI had improved OAB symptoms if BNI was successfully corrected after anti-incontinence surgery.

Prevalence of urinary incontinence among women in Saudi Arabia: a cross-sectional study.

OBJECTIVE: Urinary incontinence is defined as involuntary loss of urine, a common health condition that is more frequent in women. It disturbs the affected individuals and interferes with their daily activities. This study aimed to estimate the prevalence of urinary incontinence among Saudi women in the western area of the Kingdom of Saudi Arabia. SUBJECTS AND METHODS: A descriptive cross-sectional design was used for this study. A survey was administered to Saudi women in the western area of the Kingdom of Saudi Arabia ranging in age from 18 to 70 years. The data were collected using the Arabic version of the Questionnaire for Urinary Incontinence Diagnosis. Descriptive statistics were generated by calculating numbers and percentages of information on the prevalence of incontinence in women. p-values < 0.05 were considered statistically significant. RESULTS: The prevalence of urinary incontinence was 44.2%, with the urge type being the most reported. Stress urinary incontinence was reported by 155 women (15.4%), urgency urinary incontinence by 257 women (25.6%), and mixed urinary incontinence by 102 women (10.15%). CONCLUSIONS: Urinary incontinence is prevalent in women in Western Saudi Arabia. Age, multiparty obesity, and vaginal surgery are significant risk factors influencing its occurrence.

Increased risk of stress urinary incontinence surgery after hysterectomy for benign indication-a population-based cohort study.

BACKGROUND: Hysterectomy is a common procedure used to treat different gynecologic conditions. The association between hysterectomy for benign indication and stress urinary incontinence has previously been established. Stress urinary incontinence can be treated surgically, and options have improved after introduction of the midurethral sling procedure in 1998. OBJECTIVE: This study aimed to estimate the risk of stress urinary incontinence surgery after hysterectomy for benign indication. STUDY DESIGN: The study was carried out as a matched register-based cohort study including Danish women born from 1947 to 2000. Women who underwent hysterectomy for benign indication were matched to nonhysterectomized women in a 1:5 ratio on the basis of age and calendar year of hysterectomy. The risk of stress urinary incontinence surgery after hysterectomy was estimated. We adjusted for income, educational level, and parity. The risk of stress urinary incontinence surgery was further estimated in a subcohort excluding all vaginal hysterectomies. The joint effect of hysterectomy and parity was estimated in the main cohort, and the joint effect of hysterectomy and vaginal birth or cesarean delivery on stress urinary incontinence surgery was explored in a subgroup of women who only had 1 mode of delivery. All analyses were made using the Cox proportional hazards model. RESULTS: We included 83,370 women who underwent hysterectomy and 413,969 reference women. The overall risk of stress urinary incontinence surgery was more than doubled for women who underwent hysterectomy (adjusted hazard ratio, 2.6; 95% confidence interval, 2.4-2.8). The adjusted hazard ratio decreased slightly to 2.4 (95% confidence interval, 2.3-2.6) when excluding all vaginal hysterectomies. We found a trend of increasing risk of stress urinary incontinence surgery with increased parity among both women who underwent hysterectomy and the reference group. In the subgroup of women who only had 1 mode of delivery, we found the risk of stress urinary incontinence surgery to be particularly increased for women with a history of ≥1 vaginal births. The hazard ratio was 15.1 (95% confidence interval, 10.3-22.1) for women with a history of 1 vaginal birth who underwent hysterectomy, whereas the hazard ratio for women in the reference group with 1 vaginal birth was 5.1 (95% confidence interval, 3.8-8.1). Overall, women who underwent hysterectomy had a 3 times higher risk of stress urinary incontinence surgery than the reference group, irrespective of the number of vaginal births. CONCLUSION: This study indicates, in accordance with previous studies, that hysterectomy increases the risk of subsequent stress urinary incontinence surgery. Women should be informed and gynecologists include this knowledge in decision-making. Further precautions should be taken when treating parous women, particularly those with a history of ≥1 vaginal births.

The prevalence and risk factors of different degrees of stress urinary incontinence in Chinese women: A community-based cross-sectional study.

AIM: To investigate the prevalence of SUI and explore the factors that could influence the severity of SUI in adult females. DESIGN: A cross-sectional study. METHODS: A total of 1178 subjects were assessed using a risk-factor questionnaires and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and then divided into no SUI group, mild SUI group and moderate-to-severe SUI group according to the ICIQ-SF score. Univariate analysis between adjacent groups and ordered logistic regression models in three groups were then performed to analysis the possible associated factor with the progressive of SUI. RESULTS: The prevalence of SUI among adult women was 22.2% of them; 16.2% and 6% had mild SUI and moderate-to-severe SUI, respectively. Moreover, logistic analysis revealed that age, BMI, smoking, position preference for urination, urinary tract infections, urinary leaks during pregnancy, gynaecological inflammation and poor sleep quality were independent risk for the severity of SUI. CONCLUSION: SUI symptoms were mostly mild among Chinese females, specific risk factors such as unhealthy living habits and urination behaviours increased the risk of SUI and the aggravation of symptoms. Therefore, targeted interventions should be formulated for women to delay disease progression.

The Efficacy and Safety of Single-Incision Mini-Slings for Stress Urinary Incontinence: A Network Meta-Analysis.

PURPOSE: To evaluate the efficacy and safety of single-incision mini-sling for stress urinary incontinence based on network Meta-analysis. MATERIALS AND METHODS: We searched PubMed, Embase, and Cochrane libraries from August 2008 to August 2019. Randomized controlled trials comparing two or more indicators of Miniarc (Single Incision Mini-slings), Ajust (Adjustable Single-Incision Sling), C-NDL (Contasure-Needleless), TFS (Tissue Fixation System), Ophria (Transobturator Vaginal Tap), TVT-O (Transobturator Vaginal Tape), and TOT (Trans-obturatortape) in treating female stress urinary incontinence were collected. RESULTS: Totally, 3,428 patients from 21 studies were included. Ajust had the highest subjective cure rate (Rank=0.52), while Ophira had the worst (Rank=0.67). TFS had the highest objective cure rate, and the worst was found in Ophira. TFS required the shortest operating time (Rank=0.40), while TVT-O required the longest operating time (Rank=0.47). Miniarc had the least bleeding (Rank=0.47), while TVT-O had the most bleeding (Rank=0.37). C-NDL had the shortest postoperative hospital stay (Rank=0.77), while Ajust had the longest postoperative hospital stay (Rank=0.36). For postoperative complications, TFS performed best in groin pain (Rank=0.84), urinary retention (Rank=0.78), and repeat surgery (Rank=0.45). TVT-O performed worst in groin pain (Rank=0.36), and urinary retention (Rank=0.58). Miniarc had the highest repeat surgery rate (Rank=0.35). Ajust had the lowest probability of tap erosion (Rank=0.30), while Ophira had the highest tap erosion level (Rank=0.45). Miniarc showed the greatest advantage in urinary tract infections (Rank=0.84) and de novo urgency (Rank=0.60), while C-NDL had the highest incidence of urethral infections (Rank=0.51). Ophira performed worst in de novo urgency (Rank=0.60). C-NDL performed the best in sexual intercourse pain (Rank=0.79) while Ajust was the worst (Rank=0.49). CONCLUSIONS: In view of comprehensive efficacy and safety, we recommend that TFS or Ajust should be selected first for single-incision sling and the application of Ophria should be minimized.

Prevalence and Risk Factors for Urinary Incontinence in Nulliparous Women: A Contemporary, Population-Based Cohort Study.

IMPORTANCE AND OBJECTIVES: Epidemiologic studies of incontinence largely focus on parous women, and there are limited data regarding nulliparous women. Our objectives were to evaluate risk factors for urinary incontinence among a nationally representative, contemporary sample of nulliparous women of all ages in the United States and to describe the prevalence and subtypes of urinary incontinence and nocturia in this population. STUDY DESIGN: This cross-sectional, population-based study used the National Health and Nutrition Examination Survey cycles 2011-2018 to assemble a sample of nulliparous women 20-80 years old. Crude and adjusted odds ratios were estimated using multivariable logistic regression for the exposures of interest: body mass index (BMI), age, physical activity, prior hysterectomy, and current smoking. Prevalence of urinary incontinence and nocturia were estimated. RESULTS: Among 1,603 nulliparous women, prevalence of any urinary incontinence was 29.38%. Prevalence of stress, urgency, and mixed urinary incontinence and nocturia, respectively, were 27.68%, 19.64%, 10.57%, and 58.95%. Women with a BMI ≥25 (calculated as weight in kilograms divided by height in meters squared; adjusted odds ratio [aOR], 1.57; 95% confidence interval [CI], 1.11-2.23), at least 45 years (aOR, 3.75; 95% CI, 2.31-5.83), and current smoking (aOR, 1.63; 95% CI, 1.07-2.49) had increased the odds of incontinence compared with women without these risk factors. When stress urinary incontinence (SUI) was considered alone, only women with a BMI ≥25 (aOR, 1.66; 95% CI, 1.20-2.31) and age at least 45 years (aOR, 3.17; 95% CI, 2.01-5.00) had increased odds of SUI compared with women without these risk factors. CONCLUSIONS: Urinary incontinence and nocturia are prevalent in nulliparous women, and age, elevated BMI, and current smoking may represent risk factors for incontinence in this population.

Stress Urinary Incontinence After Operations for Uterine Prolapse: A Nationwide Cohort Study.

IMPORTANCE: Concomitant surgery for stress urinary incontinence (SUI) during pelvic organ prolapse (POP) operations are debated. OBJECTIVES: We aimed to assess the risk of an SUI operation after a uterine prolapse operation and compare the risk after the Manchester procedure versus vaginal hysterectomy. STUDY DESIGN: We performed a nationwide historical cohort study including women with no history of hysterectomy undergoing the Manchester procedure (n = 6065) or vaginal hysterectomy (n = 9,767) for POP during 1998 to 2018. We excluded women with previous surgery for SUI and POP, concomitant surgery for SUI (n = 34, 0.2%), and diagnosed with gynecological cancer before or within 90 days from surgery. Women were followed up until SUI operation/death/emigration/diagnosis of gynecological cancer/December 31, 2018, whichever came first. Women undergoing the Manchester procedure were censored if they had undergone hysterectomy.We assessed the rate of SUI surgery with cumulative incidence plots. We performed Cox Regression to analyze the risk of SUI surgery, adjusting for age, calendar year, income level, concomitant surgery in anterior and posterior compartments, and diagnosis of SUI before POP operation. RESULTS: We found that 12.4% women with and 1.6% without SUI diagnosed before the POP surgery who underwent SUI surgery within 10 years.During follow-up (median, 8.5 years), 129 (2.1%) underwent SUI surgery after the Manchester procedure and 175 (1.8%) after vaginal hysterectomy (adjusted hazard ratio, 1.06 [0.84-1.35]). CONCLUSIONS: Of women diagnosed with SUI before POP operation 1 in 8 subsequently underwent SUI surgery. Few women not diagnosed with SUI subsequently underwent SUI surgery. There was no difference in risk of SUI after the Manchester procedure and vaginal hysterectomy.

Impact of COVID-19 on surgical procedures for stress urinary incontinence in the Brazilian public health system.

INTRODUCTION AND HYPOTHESIS: The objective was to characterize the impact of the COVID-19 pandemic on the surgical treatment of female stress urinary incontinence (FSUI) in Brazil. METHODS: This study was conducted with population-based data from the Brazilian public health system database. We obtained data on the number of surgical procedures for FSUI in 2019 (before the coronavirus disease [COVID-19] pandemic), 2020, and 2021 (during the pandemic) in each of the 27 Brazilian states. We included official Brazilian Institute of Geography and Statistics (IBGE) data on the population, Human Development Index (HDI), and annual per capita income of each state. RESULTS: A total of 6,718 surgical procedures for FSUI were performed in the Brazilian public health system in 2019. The number of procedures was reduced by 56.2% in 2020, and an additional reduction of 7.2% was seen in 2021. The distribution of procedures by state showed important differences, ranging from 4.4 procedures/1,000,000 inhabitants in Paraíba and Sergipe to 67.6 procedures/1,000,000 inhabitants in Paraná (p<0.01) in 2019. The number of surgical procedures was higher in states with a higher HDI (p=0.0001) and per capita income (p=0.042). The decrease in the number of surgical procedures affected the whole country and its rate did not correlate with HDI (p=0.289) or per capita income (p=0.598). CONCLUSION: The impact of the COVID-19 pandemic on the surgical treatment of FSUI in Brazil was significant in 2020 and persisted in 2021. Access to surgical treatment of FSUI varied according to geographic region, HDI, and per capita income, even before COVID-19.

Incidence of de novo stress urinary incontinence following minimally invasive sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: The objective was to investigate the incidence and risk factors of postoperative de novo stress urinary incontinence (SUI) in stress-continent women following minimally invasive sacrocolpopexy without an anti-incontinence procedure. METHODS: We completed a multicenter, retrospective cohort study of women undergoing laparoscopic sacrocolpopexy without concurrent anti-incontinence procedures from October 2006 through January 2021. RESULTS: Of the 169 women who underwent minimally invasive sacrocolpopexy, 17.1% (n=30) developed de novo SUI, and 7.1% eventually underwent a midurethral sling placement. On logistic regression, BMI, preoperative urinary urgency, and history of transvaginal mesh repair were found to be significantly associated with and predictive of de novo SUI. When the concordance index (C-index) was calculated with the model published by Jelovsek et al. for women who developed de novo SUI within 12 months of the prolapse surgery, the current de novo SUI calculator was able to discriminate de novo SUI outcome (C-index = 0.71). CONCLUSIONS: The incidence of de novo SUI after minimally invasive sacrocolpopexy without anti-incontinence procedure correlates directly with higher BMI, preoperative urinary urgency, and transvaginal mesh history for POP. Preoperative counseling for minimally invasive sacrocolpopexy should include discussing the risk of de novo SUI and preoperative factors that may increase this risk.

The influence of pregnancy, parity, and mode of delivery on urinary incontinence and prolapse surgery-a national register study.

BACKGROUND: The long-term effects of vaginal delivery, parity, and pregnancy on the pelvic floor remain uncertain and controversial issues. In comparison with studies using self-reported symptoms, surgical register data may offer a more valid means for evaluating the relative influence of these risk factors. OBJECTIVE: This study used data from 3 high-quality nationwide registers, namely the Swedish National Quality Register of Gynecological Surgery, the Swedish Medical Birth Register, and the Total Population Register, to evaluate the contribution of vaginal and cesarean delivery, parity, and factors not related to childbirth to the long-term risk for reconstructive urogenital surgery. STUDY DESIGN: This was a register-based linkage study among women aged ≥45 years who underwent urinary incontinence or prolapse surgery from 2010 to 2017. This surgical cohort was divided into nulliparous women, women with ≥1 cesarean deliveries only, those with ≥1 vaginal deliveries, and according to the number of births. A corresponding reference group was constructed based on women born in 1960 from the Total Population Register (n=2,309,765). The Swedish Medical Birth Register was used to determine the rate of women with cesarean and vaginal delivery and their respective parity. Absolute and relative risk were presented per 1000 women with 95% confidence intervals. Pairwise differences were analyzed with Fisher exact tests and the Mann-Whitney U test for dichotomous and continuous variables. The trend between ≥3 ordered categories of dichotomous variables was analyzed with Mantel-Haenszel statistics. RESULTS: A total of 39,617 women underwent prolapse surgery and 20,488 underwent incontinence surgery. Among women with prolapse surgery, 97.8% had ≥1 vaginal delivery, 0.4% had ≥1 cesarean delivery only, and 1.9% were nullipara. Corresponding figures for those with incontinence surgery were 93.1%, 2.6%, and 4.3%, respectively. Women with vaginal deliveries were overrepresented in the prolapse surgery (relative risk, 1.23; 95% confidence interval, 1.22-1.24; P<.001) and incontinence surgery groups (relative risk, 1.17; 95% confidence interval, 1.15-1.19; P<.001). Nulliparous and cesarean delivered women were underrepresented in the prolapse surgery (relative risk, 0.14; 95% confidence interval, 0.13-0.15 and relative risk 0.055; 95% confidence interval, 0.046-0.065; all P<.001) and incontinence surgery groups (relative risk, 0.31; 95% confidence interval, 0.29-0.33 and relative risk, 0.40; 95% confidence interval, 0.36-0.43). The absolute risk for prolapse surgery was lowest after cesarean delivery (0.09 per 1000 women; 95% confidence interval, 0.08-0.11) and differed by a factor of 23 (absolute risk, 2.11 per 1000 women; 95% confidence interval, 2.09-2.13) from that after vaginal birth. The absolute risk for prolapse and incontinence surgery increased consistently with parity after vaginal births. This trend was not observed after cesarean delivery, which is on par with that of nulliparous women. The first vaginal birth contributed the highest increase in the absolute risk for pelvic organ prolapse surgery (6-fold) and stress urinary incontinence surgery (3-fold). The second vaginal birth contributed the lowest increase in the absolute risk for pelvic organ prolapse surgery (∼1/3 of the first vaginal birth) and for stress urinary incontinence surgery (∼1/10 of the first vaginal birth). CONCLUSION: Surgery for urinary incontinence and prolapse was almost exclusively related to vaginal parity. The risk for prolapse surgery increased consistently with parity after vaginal births but not after cesarean delivery, whereas the risk associated with cesarean delivery was on par with that of nulliparous women. Thus, cesarean delivery seems to offer protection from the need for pelvic organ prolapse and stress urinary incontinence surgery later in life.

Reoperation rates for stress urinary incontinence and pelvic organ prolapse in women after undergoing Mid-Urethral sling with or without concomitant colporrhaphy in academic centers within the United States.

In this study, the rates of reoperation for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) in women who underwent a mid-urethral sling (MUS) with or without concurrent colporrhaphy were evaluated. An academic faculty practice consortium database was used to identify a cohort of patients treated surgically for SUI with or without concurrent POP repair (apical, anterior, posterior, or a combination of the three) with or without hysterectomy between 2009 and 2011. A total of 20,484 patients matched the criteria. Of patients who underwent a MUS, 7.2% underwent secondary surgery, with a higher rate of 8.6% associated with those who underwent concurrent prolapse repair (Apical repair HR 1.84, p < .01; Anterior compartment repair HR 1.47, p < .01). Concurrent hysterectomy was associated with a lower hazard of secondary prolapse surgery (HR 0.48; p < .01) if the initial surgery involved a complete POP repair. Prolapse mesh repair resulted in a higher hazard of additional surgery (HR 1.43, p < .01). Medicaid insurance was also associated with an increased hazard ratio compared to commercial insurance for secondary surgery (HR 1.32, p < .01). For women undergoing MUS with complete prolapse repair, concurrent hysterectomy is associated with lower secondary surgery rates. Concurrent prolapse repair with mesh is associated with higher secondary surgery rates.Synopsis: For women undergoing MUS (mid-urethral sling) with complete prolapse repair, concurrent hysterectomy is associated with lower secondary surgery rates. Concurrent prolapse repair with mesh is associated with higher secondary surgery rates.Impact StatementWhat is already known on this subject? Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) can present at the same time and negatively impact patients' quality of life. There is little data regarding reoperation rates for patients who undergo both MUS and colporrhaphy in one setting.What do the results of this study add? This study found that patients who undergo concurrent MUS (mid-urethral sling) and complete POP repair with the addition of hysterectomy had a lower risk of secondary surgery.What are the implications of these findings for clinical practice and/or further research? Our data can be used by surgeons to counsel patients on the risks of re-operation for SUI for those who would like to undergo concurrent POP repair with or without hysterectomy.

Risk Factors for Bladder Perforation at the Time of Retropubic Midurethral Sling Placement.

IMPORTANCE: There is conflicting evidence regarding predictive factors for bladder perforation during retropubic midurethral sling (R-MUS) placement and lack of evidence to support adoption of techniques to minimize such injury. OBJECTIVES: The aims of the study were to describe the incidence of and factors associated with bladder perforation during R-MUS placement and to explore whether retropubic hydrodissection decreases the likelihood of perforation. STUDY DESIGN: This is a case-control study of women undergoing R-MUS placement from 2007 to 2017. Cases were identified by review of the operative reports for evidence of bladder perforation. Patients without bladder perforation were defined as controls and were matched to cases in a 3:1 ratio by surgeon, sling type, and surgery date. RESULTS: A total of 1,187 patients underwent R-MUS placement. The incidence of bladder perforation was 8% (n = 92 patients); 276 controls were matched accordingly (N = 368). Patients with bladder perforations were more likely to have a body mass index (BMI) less than 30 (P = 0.004) and to have a diagnosis of endometriosis (P = 0.02). They were also more likely to have had previous hysterectomy (P = 0.03) and urethral bulking (P = 0.01). On logistic regression, bladder perforation remained associated with a BMI less than 30 (adjusted odds ratio, 2.22 [95% confidence interval, 1.30-3.80]) and endometriosis (adjusted odds ratio 2.90 [95% confidence interval, 1.15-7.01]). Retropubic hydrodissection was performed in 62% of the patients and was not associated with a lower risk of perforation (P = 0.86). CONCLUSIONS: The incidence of bladder perforation was 8%. The risk of this complication is higher in patients with a BMI less than 30 and/or endometriosis. Retropubic hydrodissection may not decrease the likelihood of this event.

Relationship between exposure to cadmium, lead, and mercury and the occurrence of urinary incontinence in women.

Cadmium, lead, and mercury are nephrotoxic metals that are commonly found as hazardous pollutants in many areas of the USA. We examined the relationship between exposure to cadmium, lead, and mercury with the occurrence of urgency urinary incontinence (UUI) and stress urinary incontinence (SUI) in women. This study was conducted using data on women > 20 years of age, collected between 2005 and 2016, who reported experiencing urinary incontinence in the National Health and Nutrition Examination Survey (NHANES). Restricted cubic spline analysis was used to characterize a dose-response relationship between continuous exposure to different nephrotoxic metals and the occurrence of UUI and SUI. A total of 4406 women were included in this study, with 2624 (59.6%) suffering from SUI and 3177 (72.1%) suffering from UUI in the weighted population. The results of our multivariate analysis indicated that age, race, marital status, body mass index (BMI), and exposure to nephrotoxic metals were risk factors for developing UI. The odds ratio (OR; 95% confidence interval) for developing UI was positively correlated with the exposure to cadmium and lead in women. The OR of SUI occurrence increased with increasing levels of cadmium in blood, with a peak at 4 µg/L. The OR of UUI occurrence increased with increasing levels of blood and urinary lead, with peaks at 7 µg/dL and 5 µg/L, respectively. The presence of mercury was not significantly correlated with the occurrence of SUI or UUI. Exposure to high levels of cadmium and lead, which are nephrotoxic metals, is associated with the occurrence of UI in women.

Hormonal Influence in Stress Urinary Incontinence During Pregnancy and Postpartum.

Hormonal changes have been proposed as an etiological factor of stress urinary incontinence (SUI) during pregnancy. Our main objective was to demonstrate the role of hormones in SUI development during pregnancy and postpartum. A prospective longitudinal study was designed. Primiparous women without previous urinary incontinence symptoms were included. Symptoms and Quality of Life (QoL) Questionnaires, physical examinations, and hormone concentration (progesterone, estradiol, and relaxin) were collected twice during pregnancy and three times during postpartum. Logistic regression models, with Wald's forward variable selection method, were used. Prevalence of SUI was 11% in the first trimester, 50% in the third trimester, and 16.4% at 6 months postpartum. The risk of developing SUI throughout pregnancy is higher in women with higher progesterone concentration in the first trimester (OR 1.38, 95% CI 1.06-1.81, p < 0.05) and it is lower in women with stronger pelvic floor muscles in the first trimester (OR 0.35, 95% CI 0.17-0.72, p < 0.05). When occurred during pregnancy, SUI has a 14-fold higher risk of persistence 6 months after birth. In addition, the severity of these symptoms is also an independent risk factor for SUI persistence at 6 months postpartum (OR 1.41, 95% CI 1.15-1.73, p < 0.05). Quality of Life was affected for pregnant women with SUI symptoms. SUI is a highly prevalent condition during pregnancy, affecting the QoL of women in many areas. Higher concentration of progesterone can play a role in SUI development during pregnancy. The presence and severity of SUI during pregnancy are risk factors for the persistence of symptoms 6 months postpartum. Sustaining an optimal pelvic floor muscle strength could prevent SUI during pregnancy.

Characterizing persistent urinary incontinence after successful fistula closure: the Uganda experience.

BACKGROUND: Obstetric fistula is a devastating childbirth injury. Despite successful closure of the fistula, 16% to 55% of women suffer from persistent urinary incontinence after surgery. OBJECTIVE: This study assessed the type and severity of persistent incontinence after successful fistula closure and its impact on the quality of life of Ugandan women post-fistula treatment. STUDY DESIGN: This cross-sectional study enrolled women with a history of obstetric fistula repair who continued to have persistent urinary incontinence (cases, N=36) and women without incontinence (controls, N=52) after successful fistula closure. Data were collected in central and eastern Uganda between 2017 and 2019. All the participants completed a semistructured questionnaire. Cases underwent a clinical evaluation and a 2-hour pad test and completed a series of incontinence questionnaires, including two novel tools designed to assess the severity of incontinence in low-literacy populations. RESULTS: Cases were more likely to have acquired a fistula during their first delivery (63% vs 37%, P=.02), were younger when they developed a fistula (20.3±5.8 vs 24.8±7.5 years old, P=.003), and were more likely to have had >2 fistula surgeries (67% vs 2%, P≤.001). Cases reported a much higher rate of planned home birth for their index pregnancy compared to controls (44% vs 11%), though only 14% of cases and 12% of controls actually delivered at home. Cases reported higher rates of pain with intercourse (36% vs 18%, P=.05), but recent sexual activity status (intercourse within the previous six months) was not significantly different between the groups (47% vs 62%, P=.18). Among cases, 67% reported stress incontinence, 47% reported urgency incontinence, and 47% reported mixed incontinence. The cough stress test was successfully done with 92% of the cases, and of these, almost all (97%) had a positive cough stress test. More than half (53%) rated their incontinence as "very severe," which was consistent with objective findings. The 24-hour voiding diary indicated both high urinary frequency (average 14) and very frequent leakage episodes (average 20). Two-hour pad-tests indicated that 86% of cases had >4 g change in pad weight within 2 hours. Women with more severe incontinence reported a more negative impact on their quality of life. The mean score of the International Consultation on Incontinence Questionnaire-Quality of Life was 62.77±12.76 (range, 28-76, median=67), with a higher score indicating a greater impact on the quality of life. There was also a high mental health burden, with both cases and controls reporting high rates of suicidal ideation at any point since developing fistula (36% vs 31%, P=.67). CONCLUSION: Women with obstetric fistulas continue to suffer from severe persistent urinary incontinence even after successful fistula closure. Both stress and urgency incontinence are highly prevalent in this population. Worsening severity of incontinence is associated with a greater negative impact on the quality of life.

Profile of women with pelvic organ prolapse at the University Hospital of the West Indies risk factors and presentation.

POP affected 40% of participants in the WHI trial. Risk factors include parity, vaginal delivery, large babies, advancing age, obesity, hysterectomy and lifting. Data suggest African-American women have a lower prevalence of symptomatic POP than other racial groups. Literature review did not show a study of risk factors and symptoms in a black population. Cross-sectional study of women with POP attending urogynaecology clinic at the UHWI from May to October 2013, using an interviewer administered questionnaire was performed and analysed using SPSS version 19 program (SPSS Inc., Chicago, IL). One hundred and eight participants were included: 94.7% postmenopausal (mean 65.08 years) and 94.5% parous (mean 4). Risk factors included obesity (mean BMI 28.82 kg/m2), hysterectomy (28.7%), heavy lifting (51.9%) and chronic cough (13.9%). Symptoms included stress incontinence (40.7%), stranguria (16.7%), faecal incontinence (13.9%), constipation (31.5%), coital urinary and faecal incontinence (6.3%, 12.6%). We concluded risk factors for POP in this population correlates with other studies. Stress urinary incontinence and constipation most frequently reported symptoms in this population.Impact StatementWhat is already known on this subject? Pelvic organ prolapse (POP) is a common condition with multifactorial aetiology. As seen in systematic reviews (Vergeldt TFM, Weemhoff M, IntHout J, Kluivers KB. 2015. Risk factors for pelvic organ prolapse and its recurrence: a systematic review. International Urogynecology Journal 26(11):1559-1573). Study shows white women appeared to have more overall symptoms both from prolapse, as well as urinary symptoms, as compared with black women (Ford AT, Eto CU, Smith M, Northington GM. 2019. Racial differences in pelvic organ prolapse symptoms among women undergoing pelvic reconstructive surgery for prolapse. Female Pelvic Medicine & Reconstructive Surgery 25:130-133).What do the results of this study add? The result highlights the fact that Black women are exposed to similar risk factors and have similar symptoms to other racial groups for POP.What are the implications of these findings for clinical practice and/or further research? These findings can be used to educate women with risk factors about the possibility of developing symptomatic POP. Further research is needed to ascertain the prevalence of POP and to assess knowledge and attitude in this population as we hypothesise that there is generalised assumption in that being black is protective from POP.
