Examining the Role of Frailty on Treatment Patterns and Complications Among Older Women Undergoing Procedure-Based Treatment for Urinary Incontinence.

BACKGROUND: Aging beyond 65 years is associated with increased prevalence of urinary incontinence (UI), frailty, and increased complication rate with UI treatments. To investigate this relationship, we examined frailty as a predictor of procedure-based UI treatment patterns and urologic complications in Medicare-eligible women. METHODS: We identified women undergoing procedures for UI between 2011 and 2018 in the 5% limited Medicare data set. A claims-based frailty index (CFI) using data from the 12 months prior to the index procedure defined frailty (CFI ≥0.25). Urologic complications were assessed during the 12 months following the index procedure. We used unadjusted logistic regression models to calculate odds of having a specific type of UI procedure based on frailty status. Odds of postprocedure urologic complications were examined with logistic regression adjusted for age and race. RESULTS: We identified 21 783 women who underwent a procedure-based intervention for UI, of whom 3 826 (17.5%) were frail. Frail women with stress UI were 2.6 times more likely to receive periurethral bulking (95% confidence interval [CI] 2.26-2.95), compared to nonfrail. Conversely, frailty was associated with lower odds of receiving a Sling or Burch colposuspension. Among women with urgency UI or overactive bladder, compared to nonfrail, frailty was associated with higher odds of both sacral neuromodulation (odds ratio [OR] = 1.21, 95% CI: 1.11-1.33) and intravesical Botox (OR = 1.16, 95% CI: 1.06-1.28), but lower odds of receiving posterior tibial nerve stimulation. Frailty was associated with higher odds of postprocedure urologic complications (OR = 1.64, 95% CI: 1.47-1.81). CONCLUSIONS: Frailty status may influence treatment choice for treatment of stress or urgency UI symptoms and increase the odds of postprocedural complications in older women.

Injection site number and outcomes of intradetrusor onabotulinumtoxinA for refractory overactive bladder syndrome: a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: The optimal number of onabotulinumtoxinA injections for the treatment of refractory overactive bladder syndrome is unknown. Our primary objective was to determine whether 10-injections sites with 100 units of onabotulinumtoxinA each were associated with less pain than 20-injections sites. METHODS: In a single-blinded randomized trial, 100 units of onabotulinumtoxinA was administered, either as 10 × 1 ml or as 20 × 0.5 ml injections following the instillation of 30 ml of bupivacaine and 5 ml of NaHCO3 solution for 15 min. The primary outcome was procedural pain, as measured on an 11-point Numerical Pain Rating Scale (NPRS) immediately following the procedure. A power calculation estimated that 16 subjects in each arm were needed to detect a mean difference of 1 with a standard deviation of 1, on the NPRS score between the two treatment groups, with α 0.05 and power 80%. To adjust for an estimated 20% dropout rate, the final sample size was planned for 20 patients per group. RESULTS: From October 2020 to November 2022, a total of 56 patients were approached and 40 were enrolled and randomized to two groups (21 in the 10-injections group and 19 in 20-injections group). The difference in the median pain score between the group was not statistically significant (4 [1.5-5] for 10 injections vs 3 [1-4] for 20 injections, p=0.823). CONCLUSION: Patients' perception of pain, efficacy, and adverse events did not significantly differ between patients receiving 10 and those receiving 20 injections of 100 units of onabotulinumtoxinA.

Skeletal Muscle Health, Physical Performance, and Lower Urinary Tract Symptoms in Older Adults: the Study of Muscle, Mobility and Aging (SOMMA).

BACKGROUND: Lower urinary tract symptoms (LUTS) and mobility limitations are bidirectionally associated among older adults, but the role of skeletal muscle remains unknown. We evaluated cross-sectional associations of muscle health and physical performance with LUTS. METHODS: We used data from 377 women and 264 men age>70 years in the Study of Muscle, Mobility and Aging (SOMMA). LUTS and urinary bother were assessed using the LURN Symptom Index-10 (SI-10;higher=worse symptoms). Muscle mass and volume were assessed using D3-creatine dilution (D3Cr) and magnetic resonance imaging. Grip strength and peak leg power assessed upper/lower extremity physical performance. 400m walk, Short Physical Performance Battery (SPPB), and Four Square Step Test (FSST) assessed global physical performance. Mobility Assessment Tool-short form (MAT-sf) assessed self-reported mobility. We calculated Spearman correlation coefficients adjusted for age, BMI, multimorbidity, and polypharmacy, chi-square tests, and Fisher's Z-test to compare correlations. RESULTS: Among women, LURN SI-10 total scores were inversely correlated with FSST (rs=0.11,P=0.045), grip strength (rs=-0.15,P=0.006), and MAT-sf (rs=-0.18,P=0.001), but not other muscle and physical performance measures in multivariable models. LURN SI-10 was not associated with any of these measures among men. 44% of women in the lowest tertile of 400m walk speed versus 24% in the highest tertile reported they were at least "somewhat bothered" by urinary symptoms (P<0.001) whereas differences among men were not significant. CONCLUSIONS: Balance and grip strength were associated with LUTS severity in older women but not men. Associations with other muscle and physical performance measures varied by LUTS subtype but remained strongest among women.

Financial analysis of minimally invasive sacrocolpopexy compared with native tissue vaginal repair with concomitant hysterectomy.

INTRODUCTION: Minimally invasive sacrocolpopexy (MISCP) is increasingly used for uterovaginal prolapse, but comparative cost data of MISCP versus native tissue vaginal repair (NTR) are lacking. The objective was to determine the cost difference, from a hospital perspective, between MISCP and NTR performed with hysterectomy for uterovaginal prolapse. METHODS: This was a retrospective cohort study at a tertiary care center of women who underwent NTR or MISCP with concomitant hysterectomy in 2021. Hospital charges, direct and indirect costs, and operating margin (revenue minus costs) were obtained from Strata Jazz and compared using SPSS. RESULTS: A total of 82 women were included, 33 MISCP (25 robotic, 8 laparoscopic) versus 49 NTR. Demographic and surgical data were similar, except that MISCP had younger age (50.5 vs 61.1 years, p<0.01). Same-day discharge and estimated blood loss were similar, but operative time was longer for MISCP (204 vs 161 min, p<0.01). MISCP total costs were higher (US$17,422 vs US$13,001, p<0.01). MISCP had higher direct costs (US$12,354 vs US$9,305, p<0.01) and indirect costs (US$5,068 vs US$3,696, p<0.01). Consumable supply costs were higher with MISCP (US$4,429 vs US$2,089, p<0.01), but the cost of operating room time and staff was similar (US$7,926 vs US$7,216, p=0.07). Controlling for same-day discharge, anti-incontinence procedures and smoking, total costs were higher for MISCP (adjusted beta = US$4,262, p<0.01). Mean charges (US$102,060 vs US$97,185, p=0.379), revenue (US$22,214 vs US$22,491, p=0.929), and operating margin (US$8,719 vs US$3,966, p=0.134) were not statistically different. CONCLUSION: Minimally invasive sacrocolpopexy had higher costs than NTR; however, charges, reimbursement, and operating margins were not statistically significantly different between the groups.

An assessment of urethral radiation exposure in the treatment of endometrial and rectal cancers.

INTRODUCTION AND HYPOTHESIS: Female survivors of endometrial and rectal cancers have increased risk of urinary incontinence. Survivors with prior radiation therapy are counseled against mesh incontinence surgery. We hypothesize that urethral radiation dose varies based on modality which may influence surgical risks. We aimed to demonstrate urethral radiation dose differences between vaginal brachytherapy (VBT) and external beam radiation therapy (EBRT). METHODS: This is a retrospective cohort study of women exposed to VBT for endometrial cancer and EBRT for rectal cancer. The urethra was contoured on CT imaging to calculate radiation doses in centigray (cGy). The primary outcome was the percent of treatment radiation dose estimated to be received by the urethra based on the volume dose to 0.2 cc of urethra. Secondary outcomes were point doses to the bladder neck, mid-urethra, and total mean urethral dose. Descriptive statistics described demographic characteristics. Bivariate analyses compared urethral radiation dose based on radiation modality. RESULTS: Between 2014-2017, 32 women treated were included: 18 with VBT and 14 with EBRT. Mean ± SD urethral volume doses were lower in VBT (1266 cGy ± 533, 42.2% of prescribed treatment dose) compared to EBRT (5051 cGy ± 192, 100.2% of prescribed treatment dose), p < 0.0001. VBT also had significantly lower mean total urethral dose and point doses to bladder neck and mid- urethra compared to EBRT (p < 0.0001). CONCLUSIONS: The female urethra is exposed to significantly less radiation in VBT compared to EBRT. These data highlight that modality of pelvic radiation should be considered in treatment counseling on urinary incontinence in women.

Examining the Role of Nonsurgical Therapy in the Treatment of Geriatric Urinary Incontinence.

OBJECTIVE: To examine the role of physical function impairments on the change in urinary incontinence (UI) symptoms after pelvic floor muscle training in older women. METHODS: This is a prospective cohort study of 70 community-dwelling participants, older than age 70 years, with at least moderate incontinence symptoms. A comprehensive pelvic floor and physical function assessment was done at baseline. Individualized pelvic floor muscle training prescriptions with behavioral management strategies to reduce incontinence episodes were provided for 12 weeks. Baseline physical function was determined using the SPPB (Short Physical Performance Battery). A total score of 9 or lower out of 12 indicated impaired physical function, and scores higher than 9 indicated normal physical function. A 3-day bladder diary established daily incontinence episodes. The between-group difference in the change in number of UI episodes, from baseline to 6 weeks, was our primary outcome. Descriptive analyses compared important demographic and clinical characteristics. Longitudinal mixed model linear regression analyses determined the change in incontinence episodes and estimates of improvement based on the presence of impaired physical function and adjusted for age, race, and body mass index (BMI). RESULTS: Participants' mean±SD age was 76.9±5.4 years, and 15.7% identified as African American, with no significant differences in age or race between groups. Participants with impaired physical function had higher mean±SD BMI (33.6±14.5 vs 27.4±5.8; P=.03) and more baseline incontinence episodes (4.5±2.9 vs 2.7±2.1 episodes per day; P=.005) than in women without functional impairment. After 6 weeks of pelvic floor exercises, the change in number of incontinence episodes per day was not different between participants with physical functional impairment compared with women with normal physical function (mean [95% CI] -1.2 [-2.0 to -0.5] vs -0.4 [-1.1 to 0.3], P=.31). Overall, after 12 weeks of pelvic floor muscle training, complete satisfaction with incontinence symptom improvement was low for both groups (41.8% with physical function impairments vs 44.8% with normal physical function; P=.90). CONCLUSION: Behavioral therapy including pelvic floor muscle training may not significantly decrease UI symptoms to a degree that is satisfactory in women who are older than 70 years and are seeking treatment for UI, regardless of the presence of physical function impairments.

Gluteal and Posterior Thigh Pain From a Suture Compared With an Anchor-Based Device in Patients Undergoing Sacrospinous Ligament Fixation: A Randomized Controlled Trial.

OBJECTIVE: To compare postoperative gluteal and posterior thigh pain, device performance, and perioperative complications in women undergoing sacrospinous ligament fixation with an anchor-based compared with a suture-capturing device. METHODS: This was a single-center, patient-blinded, parallel, superiority trial of patients undergoing native-tissue pelvic organ prolapse repair through sacrospinous ligament fixation with an anchor-based compared with suture-capturing device using randomized-block randomization. The primary outcome was the increase in gluteal and posterior thigh pain from baseline to 1-week postoperation using the numerical rating scale. Pain was also assessed at postoperative day 1, week 6, and a summarized assessment for the first postoperative week. Intraoperative device performance, home opioid pain medication use, and changes in prolapse symptom scores were also analyzed. To provide 80% power to detect a pain difference of 2.5 points between the groups with an SD of 2.8 and a 15% dropout estimate using a two-sided 5% significance level, 24 patients were required per group. Analysis with Student's t test, Wilcoxon rank-sum tests, and Fisher exact tests were performed as well as an analysis of covariance for the primary outcome. RESULTS: Between September 2018 and June 2020, 47 patients (24 anchor-based and 23 suture-capturing) were included in the study. There was no significant difference between the anchor-based and suture-capture groups in mean change in gluteal and posterior thigh pain from baseline to 1-week postoperation (-0.4, 95% CI -1.6 to 2.3). The highest pain increase from baseline during the first postoperative week was also similar between the two groups (up 4.00 and up 4.74, respectively) with no significant difference between the anchor-based and suture-capture groups (-0.7, 95% CI -1.4 to 2.8). There were no differences in changes in pain at any of the other timepoints, in opioid pain medication utilization, device performance, or in prolapse symptom scores. CONCLUSION: An anchor-based device did not reduce postoperative gluteal and posterior thigh pain compared with a suture-based device after sacrospinous ligament fixation.

Voiding function after sacrocolpopexy versus native tissue transvaginal repair for apical pelvic organ prolapse in an ERAS era: A retrospective cohort study.

OBJECTIVE: The objectives of this study were to compare time to return of voiding function and associated complications in women undergoing minimally invasive sacrocolpopexy (SCP) versus transvaginal native tissue repair in patients with same-day or early discharge. METHODS: This was a retrospective cohort study conducted at a tertiary care center. The electronic medical record system was queried for women who underwent native tissue vaginal repair or SCP for apical prolapse between March and December 2020 using CPT codes for sacrocolpopexy (57425), extraperitoneal (57282), and intraperitoneal colpopexy (57283). Voiding success was our primary outcome and was defined by a postvoid residual < 150 ml. Secondary outcomes included catheter days and urinary tract infections. The total number of participants was based on a power calculation using internal institutional rates. Participants were compared based on the surgical approach. A multivariate regression analysis was performed to assess for confounding factors. RESULTS: We included 134 women: 63 SCP and 71 native tissue. The failure rate of the first postoperative voiding trial was 34 vs. 11% (odds ratio: 4.91; 95% CI 1.96-12.3, p < 0.01) in the vaginal and SCP groups, respectively. Both groups had a similar success rate of a second voiding trial (100% in SCP group vs. 95.7% in the vaginal repair group, p = 1). The total number of days (3.108 vs. 1.603 days, p < 0.01) to return of bladder function, postoperative urinary tract infections (23.9 vs. 6.35%, p < 0.01) and emergency department visits (15.5 vs. 1.59%, p < 0.01) were all higher in the vaginal repair group. CONCLUSIONS: Vaginal apical native tissue repair had a fivefold greater risk of acute postoperative urinary retention compared to sacrocolpopexy in addition to increased rates of post-operative urinary tract infection and emergency department visits for urinary tract concerns.

Characterizing the physical function decline and disabilities present among older adults with fecal incontinence: a secondary analysis of the health, aging, and body composition study.

OBJECTIVE: Unhealthy aging is associated with fecal incontinence (FI) and poor physical performance. The link between FI and physical performance in older adults is unknown. We aim to examine the longitudinal relationship between FI symptoms and physical performance among older US adults. METHODS: We analyzed a cohort of well-functioning, adults aged 70-79 years enrolled in the prospective cohort of the Health, Aging, and Body Composition study. Fecal incontinence symptoms were assessed at baseline using a validated question. Physical performance was determined by the expanded version of the Short Physical Performance Battery (HABC PBB), which includes an assessment of usual and fast walking speed and balance measures. Objective measures of physical performance were determined at baseline and year 4. Univariate and multivariate analyses compared physical performance based on presence of FI symptoms adjusting for important demographic and clinical covariates. RESULTS: Of the 2914 participants in the Health ABC cohort, 222 (8%) had FI symptoms and 2692 (92%) did not. Mean age and BMI were 73 years and 27 kg/m2, respectively. Older adults with FI symptoms demonstrated a clinically significant decline in total HABC PBB scores from baseline to year 4 of -0.33 (95% CI: -0.41, -0.25), a statistically significant difference compared to adults without FI symptoms (-0.26 [95% CI: -0.32, -0.20]), p = 0.04. Sub-scale components demonstrated greater deficits in narrow walk speed, p = 0.03, and non-significant trend in greater deficits in repeated chair rise pace and gait speed, p ≥ 0.05. CONCLUSIONS: Fecal incontinence symptoms are associated with clinically important declines in physical performance in older adults.

The geriatric incontinence syndrome: Characterizing geriatric incontinence in older women.

OBJECTIVES: Among older women, the clinical presentation of urinary incontinence (UI) is heterogeneous; presenting as a pelvic floor condition or geriatric syndrome. We aimed to characterize the geriatric incontinence syndrome (GIS) to establish its foundation in clinical practice. DESIGN: Prospective study. SETTING: Geriatric Clinical Research Unit. PARTICIPANTS: Sixty-one community-dwelling women aged 70 and older with bothersome UI symptoms. MEASUREMENTS: UI symptom type and severity were determined by 3-day bladder diary. UI severity was defined; moderate UI defined as <2 UI episodes/day and severe UI defined as ≥2 UI episodes/day. Subjective assessment of physical performance was determined using the Short Physical Performance Battery (SPPB) score. Total SPPB scores >9 define normal physical performance and scores ≤9 defined impaired physical performance. RESULTS: The average age was 77.1 ± 5.8 (mean ± SD) years; 69% of women had severe UI and 31% had moderate UI. Demographic characteristics were similar between groups. Daytime voiding frequency was 7.1 ± 2.9 and nocturia was present equally between groups. The majority of women (59%) with severe UI had SPPB ≤9 compared with 26% among women with moderate UI (p = 0.02); featuring significantly slower chair stand scores (2.3 ± 1.4 vs 3.3 ± 0.9, p = 0.007) and gait speed (0.08 ± 0.2 m/s compared with 1.0 ± 0.2 in women with moderate UI). CONCLUSIONS: A multifactorial GIS may be present in older women evidenced by the co-existence of severe UI, physical disability, slower chair stand pace, and gait speed. Prospective studies are needed to understand how these clinical features may impact the clinical care of older incontinent women.

Urinary Incontinence in Older Women: A Syndrome-Based Approach to Addressing Late Life Heterogeneity.

Urinary incontinence is a prevalent pelvic floor disorder among women of all ages. However, in many older women, especially those who have multiple chronic conditions it may be a geriatric syndrome because of its shared characteristics of physical function impairments, cognitive decline, and mobility disability. The geriatric incontinence syndrome may represent a poorly characterized phenotype of UI among older women which in many ways reflects unhealthy aging. In this article, we explore the evidence behind these concepts together with potentiel impact on the diagnosis and management of UI in this group.

Regenerative medicine for anal incontinence: a review of regenerative therapies beyond cells.

INTRODUCTION AND HYPOTHESIS: Current treatment modalities for anal sphincter injuries are ineffective for many patients, prompting research into restorative and regenerative therapies. Although cellular therapy with stem cells and progenitor cells show promise in animal models with short-term improvement, there are additional regenerative approaches that can augment or replace cellular therapies for anal sphincter injuries. The purpose of this article is to review the current knowledge of cellular therapies for anal sphincter injuries and discusses the use of other regenerative therapies including cytokine therapy with CXCL12. METHODS: A literature search was performed to search for articles on cellular therapy and cytokine therapy for anal sphincter injuries and anal incontinence. RESULTS: The article search identified 337 articles from which 33 articles were included. An additional 12 referenced articles were included as well as 23 articles providing background information. Cellular therapy has shown positive results for treating anal sphincter injuries and anal incontinence in vitro and in one clinical trial. However, cellular therapy has disadvantages such as the source and processing of stem cells and progenitor cells. CXCL12 does not have such issues while showing promising in vitro results for treating anal sphincter injuries. Additionally, electrical stimulation and extracorporeal shock wave therapy are potential regenerative medicine adjuncts for anal sphincter injuries. A vision for future research and clinical applications of regenerative medicine for anal sphincter deficiencies is provided. CONCLUSION: There are viable regenerative medicine therapies for anal sphincter injuries beyond cellular therapy. CXCL12 shows promise as a focus of therapeutic research in this field.

Optimal timing of a second postoperative voiding trial in women with incomplete bladder emptying after vaginal reconstructive surgery: a randomized trial.

BACKGROUND: Rates of postoperative incomplete bladder emptying vary significantly after pelvic reconstructive surgery. With enhanced recovery protocols the paradigm is shifting towards same-day discharge and the rates of incomplete bladder emptying are expected to increase. The optimal length of time for postoperative catheter drainage has not been clearly established. There are no current studies that assess the optimal timing of a repeat voiding trial in women who have unsuccessful same day voiding trials. OBJECTIVE: This study aimed to compare the outcomes of a second voiding trial performed 2-4 days (earlier group) vs 7 days (later group) postoperatively in women with incomplete bladder emptying after vaginal prolapse surgery. Secondary aims included postoperative urinary tract infection rates, total days with a catheter, and patient-reported catheter bother between groups. STUDY DESIGN: Across 2 sites, women undergoing multicompartment vaginal repair were enrolled. Within 6 hours postoperatively, subjects had an active retrograde voiding trial. Those who passed this voiding trial exited the study; those who had persistent incomplete bladder emptying (postvoid residual >100 mL) had a transurethral indwelling catheter placed and were randomized to return for an earlier (postoperative day 2-4) vs later (postoperative day 7) follow-up office voiding trial. Subjects were followed for 6 weeks after surgery. The primary outcome was the rate of unsuccessful repeat office voiding trial. Secondary outcomes included rates of urinary tract infection, total days with a catheter, and subjective catheter bother. A power calculation based on a projected 31% difference, a power of 0.8, and an alpha of 0.05 revealed that 30 subjects were needed in each group. RESULTS: A total of 102 subjects were enrolled; 38 exited on postoperative day 0, leaving 64 subjects for randomization (4 of whom withdrew after randomization). A comparison of data revealed that randomization was effective, with no differences between the earlier and later groups in terms of demographic data or surgical procedures. Using an intention-to-treat analysis, women in the earlier group were more likely to be unsuccessful in their follow-up office voiding trial (23.3%) than the later group (3.3%), with a risk difference of 20% (95% confidence interval, 3.56-36.44) and a relative risk of 7.00 (95% confidence interval, 0.92-53.47; P=.02). A number-needed-to-treat calculation found that for every 5 patients using a catheter for 7 days postoperatively, 1 case of persistent postoperative incomplete bladder emptying was prevented. Rates of catheter bother did not differ between groups at the time of the follow-up office voiding trial or at 6 weeks (P=.09 and P=.20, respectively). Urinary tract infection rates were higher in the earlier group but did not reach statistical significance (23% vs 7%, P=.07). Regression analysis revealed that subjects who required additional pain medication refills were 9.6 times (95% confidence interval, 1.24-73.77) more likely to have persistent incomplete bladder emptying after the follow-up office voiding trial. CONCLUSION: Women with incomplete bladder emptying after multicompartment prolapse repair had a 7-fold higher risk of an unsuccessful repeat office voiding trial if performed within 4 days of surgery than when performed within 7 days of surgery. In addition, requiring additional prescriptions for analgesia increased the risk of an unsuccessful follow-up office voiding trial.

Validation and Testing of an E-Learning Module Teaching Core Urinary Incontinence Objectives in a Randomized Controlled Trial.

OBJECTIVES: To evaluate the efficacy of a urinary incontinence (UI) e-learning module (ELM) in undergraduate medical education. METHODS: An ELM was developed and validated to teach on UI learning objectives. A 21-item assessment was developed to test knowledge gained. A randomized-controlled trial and parallel nested-cohort study were performed to test the effectiveness of the validated UI-ELM compared with standard methods of UI learning. Students were recruited and enrolled at the onset of their obstetrics and gynecology clerkship. Assignments to either a week-long rotation of gynecologic (GYN) or urogynecologic (UroGyn) surgery were made independent of the study protocol. On the GYN rotation, students were randomly assigned to the UI-ELM intervention or no intervention (control group). The nested-cohort comprised students assigned to the UroGyn rotation. Parametric statistics were applied assessing score changes between the UI-ELM versus control/UroGyn groups. RESULTS: Eighty-three students rotated between June 2015 and February 2016. Fifty-five were assigned to GYN and randomized: 35 UI-ELM versus 20 no intervention; 28 were assigned to UroGyn. Students randomized to the UI-ELM had greater score improvement compared with controls (between group difference of +2.73; 95% confidence interval, 0.53-4.93; P = 0.02). Knowledge improvement was similar between students exposed to the UI-ELM compared with those with UroGyn exposure (between group difference, +0.91; 95% confidence interval, -1.05 to 2.88; P = 0.35). CONCLUSIONS: The UI-ELM resulted in greater improvement in UI knowledge among third year medical students compared with traditional methods of learning and similar to those exposed to a UroGyn rotation.

Sex differences in lower urinary tract biology and physiology.

Females and males differ significantly in gross anatomy and physiology of the lower urinary tract, and these differences are commonly discussed in the medical and scientific literature. However, less attention is dedicated to investigating the varied development, function, and biology between females and males on a cellular level. Recognizing that cell biology is not uniform, especially in the lower urinary tract of females and males, is crucial for providing context and relevance for diverse fields of biomedical investigation. This review serves to characterize the current understanding of biological sex differences between female and male lower urinary tracts, while identifying areas for future research. First, the differences in overall cell populations are discussed in the detrusor smooth muscle, urothelium, and trigone. Second, the urethra is discussed, including anatomic discussions of the female and male urethra followed by discussions of cellular differences in the urothelial and muscular layers. The pelvic floor is then reviewed, followed by an examination of the sex differences in hormonal regulation, the urinary tract microbiome, and the reticuloendothelial system. Understanding the complex and dynamic development, anatomy, and physiology of the lower urinary tract should be contextualized by the sex differences described in this review.

Characterizing the Functional Decline of Older Women With Incident Urinary Incontinence.

OBJECTIVE: To characterize change in physical performance and differential prevalence of low skeletal muscle mass and strength (sarcopenia) and lower 25-hydroxyvitamin D concentrations among older women who developed urinary incontinence (UI) symptoms. METHODS: This is a secondary analysis of the Health, Aging, and Body Composition Study. Urinary incontinence symptoms were assessed using validated questions. The Short Physical Performance Battery measured physical performance. Sarcopenia, defined by low muscle mass and strength, was determined using validated cutoffs for gait speed, grip strength, and appendicular skeletal muscle mass. All parameters were evaluated at baseline and year 4. Serum 25-hydroxyvitamin D concentrations were assessed at year 2. The primary outcome was change in Short Physical Performance Battery total scores. Sarcopenia and lower serum 25-hydroxyvitamin D concentrations have been independently associated with poor physical performance and UI and were therefore included as secondary outcomes. Univariate and multivariate analyses were used to characterize the associations of change in physical performance from baseline to year 4, incidence of sarcopenia, and lower serum 25-hydroxyvitamin D on the development of UI symptoms. RESULTS: Of the 1,583 women enrolled, 910 were excluded (730 had baseline UI; 180 with missing data). Six hundred seventy-three women were continent at baseline; 223 (33%) developed UI symptoms at year 4. SPPB total scores significantly declined in women with UI versus continent women (mean difference continent-incident UI 0.32, 95% CI 0.04-0.60, P=.02). Of subscale measures, standing balance showed the greatest decline at 0.20 (0.05-0.36; continent-incident UI, respectively; P=.009). Sarcopenia developed at a higher rate with incident UI (adjusted odds ratio [OR] 1.7, 95% CI 1.0-2.9). Low 25-hydroxyvitamin D was not associated with incident UI (adjusted OR 1.1, 95% CI 0.7-1.6 and 1.1, 95% CI 0.7-1.6 for deficient or insufficient versus sufficient status, respectively). CONCLUSION: We observed a significant decline in standing balance among older women who developed UI symptoms. This decline may be associated with coinciding development of sarcopenia.

Expert Panel Recommendations on Lower Urinary Tract Health of Women Across Their Life Span.

Urologic and kidney problems are common in women across their life span and affect their daily life, including physical activity, sexual relations, social life, and future health. Urological health in women is still understudied and the underlying mechanisms of female urological dysfunctions are not fully understood. The Society for Women's Health Research (SWHR®) recognized the need to have a roundtable discussion where researchers and clinicians would define the current state of knowledge, gaps, and recommendations for future research directions to transform women's urological health. This report summarizes the discussions, which focused on epidemiology, clinical presentation, basic science, prevention strategies, and efficacy of current therapies. Experts around the table agreed on a set of research, education, and policy recommendations that have the potential to dramatically increase awareness and improve women's urological health at all stages of life.

Postoperative bowel function, symptoms, and habits in women after vaginal reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: The objective was to characterize postoperative bowel symptoms in women undergoing vaginal prolapse reconstructive surgery randomized to preoperative bowel preparation vs a regular diet. METHODS: Subjects (N = 121) completed two bowel diaries: a 7-day bowel diary immediately before surgery and a 14-day diary postoperatively. Self-reported bowel diary data and symptoms included the time to first bowel movement (BM), daily number of BMs, Bristol Stool Form Scale score, pain, and urgency associated with BM, episodes of fecal incontinence, and use of laxatives. Antiemetic use was abstracted from medical records. Outcomes of groups were compared using Chi-squared/Fisher's exact test or Student's t test as appropriate. RESULTS: Mean time to first postoperative BM was similar in the bowel preparation (n = 60) and control groups (n = 61), 81.2 ± 28.9 vs 78.6 ± 28.2 h, p = 0.85. With the first BM, there were no significant differences between bowel preparation and control groups regarding pain (17.2 vs 27.9 %, p = 0.17), fecal urgency with defecation (56.9 vs 52.5 %, p = 0.63), fecal incontinence (14.0 vs 15.0 %, p = 0.88) and >1 use of laxatives (93.3 vs 96.7 % p = 0.44) respectively. Antiemetic use was similar in both groups (48.3 vs 55.7 % respectively, p = 0.42). CONCLUSIONS: There were no differences in the return of bowel function and other bowel symptoms postoperatively between the randomized groups. Lack of bowel preparation does not have an impact on the risk of painful defecation postoperatively. This information may be used to inform patients regarding expectations for bowel function after vaginal reconstructive surgery.
