Urodynamic insights: exploring the relationship between detrusor overactivity and pelvic organ prolapse in women with urge incontinence.

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

Radiofrequency as the New Opportunity in Treating Overactive Bladder and Urge Urinary Incontinence-A Single-Arm Pilot Study.

Background and Objectives: Until now, overactive bladder (OAB) with or without urge urinary incontinence (UUI) has been treated mainly in two ways: with behavioral methods and patient education, or using antimuscarinic drugs and/or beta-3 adrenergic receptor agonists. Unfortunately, these drugs may cause side effects in some women or are insufficiently effective, so patients abandon them. Therefore, in this pilot study, radiofrequency was evaluated as a new option in the treatment of OAB and UUI. Materials and Methods: Nineteen patients were enrolled in this pilot study using radiofrequency (RF), where the level of OAB and UUI was assessed using the validated ICIQ-OAB questionnaire. RF was applied four times for 20 min, once a week. Two weeks after treatment, the level of OAB and UUI was reassessed and processed statistically and the treatment effect evaluated. Results: Using the ICIQ-OAB, the severity of OAB and UUI was assessed: 0-3 mild symptoms; 4-7 moderate symptoms; 8-11 severe symptoms; 12-16 very severe symptoms. Before treatment, 10.5% of patients had mild symptoms, 21.1% moderate symptoms, 63.2% severe symptoms and 5.3% very severe symptoms. After treatment, 42.9% had mild symptoms, 50% moderate symptoms and 7% severe OAB and UUI symptoms. All four main symptoms-frequency, nocturia, urgency and incontinence-decreased statistically significantly, with the best results being found in urgency (p = 0.002). Conclusions: Based on this pilot study, RF seems a very promising method in the treatment of OAB and UUI. To extend our initial findings, it is necessary to perform a prospective, randomized and placebo-controlled study in order to obtain reliable results and to determine for how long one set of treatment maintains the results obtained immediately after the end of that treatment. In this way, we may determine how often the treatment needs to be repeated, if necessary, and when.

Proximity of percutaneous tibial nerve stimulation needle insertion to surrounding anatomic structures: a cadaveric study.

BACKGROUND: Percutaneous tibial nerve stimulation is a third-line treatment for overactive bladder and urgency urinary incontinence. During the procedure, a needle is inserted cephalad to the medial malleolus and posterior to the tibia. In recent years, permanent implants and leads have been developed for insertion into the medial ankle via a small incision. There are many important structures present in the medial compartment of the ankle, including the great saphenous vein, saphenous nerve, tibial nerve, posterior tibial vessels, and tendons of the posterior compartment leg muscles. OBJECTIVE: The primary objective of this study was to identify the proximity of the percutaneous tibial nerve stimulation needle placed per Food and Drug Administration-approved device instructions to nearby important anatomic structures. The secondary objectives were to identify the proximity of the tibial nerve to the needle site, identify clinically relevant ankle anatomic structures, and confirm the tibial nerve and posterior tibial vasculature by histologic analysis. STUDY DESIGN: Detailed medial ankle dissections were performed bilaterally on 10 female lightly embalmed anatomic donors (cadavers) obtained from the Willed Body Program at the University of Louisville. A pin was inserted at the percutaneous tibial nerve stimulation needle site, and the medial ankle was minimally dissected so the surrounding anatomic structures were visible but not disrupted. The shortest distance from the pin to the selected structures of the medial ankle region was measured. On completion of each dissection and set of measurements, tissue was harvested for histologic examination. The distances between the pin and each structure were assessed using means and standard deviations. A paired t test was used to assess the difference in the locations between the left and right ankles. Statistical analysis was performed on left-sided, right-sided, and combined measurements. An 80% prediction interval was found to represent the expected range of values for the measurement of a new cadaver or patient, and the 95% confidence interval of the mean was computed to characterize the average distance across all cadavers or patients. RESULTS: The medial ankle of 10 adult female lightly embalmed cadavers were examined bilaterally. Dissections were completed from October 2021 to July 2022. Of note, 80% prediction intervals for the tibial nerve, the posterior tibial artery or vein, and the flexor digitorum longus tendon had a lower range of 0.0 mm from the pin and extending to 12.1, 9.5, and 13.9 mm, respectively. Moreover, 2 of the structures were found to be asymmetrical between the right and left ankles. The great saphenous vein was further from the pin on the left (20.5 mm [standard deviation of 6.4 mm] on the left vs 18.1 mm [standard deviation of 5.3 mm] on the right; P=.04). The calcaneal (Achilles) tendon was further from the pin on the right side (13.2 mm [standard deviation of 6.8 mm] vs 7.9 mm [standard deviation of 6.7 mm]; P=.04). Tibial neurovascular structures were confirmed with microscopic analysis. CONCLUSION: The anatomic structures within the medial ankle lie unexpectedly close to the percutaneous tibial nerve stimulation needle site as noted per Food and Drug Administration-approved device instructions. There is a possibility that some medial ankle structures are not symmetrical. It is crucial that practitioners understand medial ankle anatomy when performing percutaneous tibial nerve stimulation or permanent device insertion.

Treatment patterns in women with urinary urgency and/or urgency urinary incontinence in the symptoms of Lower Urinary Tract Dysfunction Research Network Observational Cohort Study.

BACKGROUND: Limited epidemiological data exist describing how patients engage with various treatments for overactive bladder (OAB). To improve care for patients with OAB, it is essential to gain a better understanding of how patients interface with OAB treatments longitudinally, that is, how often patients change treatments and the pattern of this treatment change in terms of escalation and de-escalation. OBJECTIVES: To describe treatment patterns for women with bothersome urinary urgency (UU) and/or urgency urinary incontinence (UUI) presenting to specialty care over 1 year. STUDY DESIGN: The Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) study enrolled adult women with bothersome UU and/or UUI seeking care for lower urinary tract symptoms (LUTS) between January 2015 and September 2016. An ordinal logistic regression model was fitted to describe the probabilities of escalating or de-escalating level of treatment during 1-year follow-up. RESULTS: Among 349 women, 281 reported UUI and 68 reported UU at baseline. At the end of 1 year of treatment by a urologist or urogynecologist, the highest level of treatment received by participants was 5% expectant management, 36% behavioral treatments (BT), 26% physical therapy (PT), 26% OAB medications, 1% percutaneous tibial nerve stimulation, 3% intradetrusor onabotulinum toxin A injection, and 3% sacral neuromodulation. Participants using BT or PT at baseline were more likely to be de-escalated to no treatment than participants on OAB medications at baseline, who tended to stay on medications. Predictors of the highest level of treatment included starting level of treatment, hypertension, UUI severity, stress urinary incontinence, and anticholinergic burden score. CONCLUSIONS: Treatment patterns for UU and UUI are diverse. Even for patients with significant bother from OAB presenting to specialty clinics, further treatment often only involves conservative or medical therapies. This study highlights the need for improved treatment algorithms to escalate patients with persistent symptoms, or to adjust care in those who have been unsuccessfully treated.

The biopsychosocial impacts of anxiety on overactive bladder in women.

AIMS: Links between emotional state and the bladder have long been recognized, as psychological comorbidity is a common feature of overactive bladder (OAB). However, how psychological factors might contribute to the development and severity of OAB remains unclear. Therefore, we sought to examine the effect of anxiety on OAB with a specific focus on bladder hypersensitivity. METHODS: In a sample of 120 adult women with OAB, we compared those with at least mild anxiety (PROMIS Anxiety score ≥55) to those with lower anxiety. Analyses focused on patient-reported questionnaires assessing urinary symptom severity and quality of life, psychological stress symptoms, general somatic symptoms, and results of quantitative sensory testing (QST), including temporal summation to heat pain (TSP). TSP was used to index elevated C-fiber responsiveness (i.e., central sensitization). RESULTS: Thirty-six (30%) women had at least mild anxiety. While there were no group differences for urinary symptom severity, more anxious women reported worse OAB-specific quality of life, greater psychological stress burden, higher stress reactivity, and greater somatic symptoms. On QST, there were no differences between anxiety groups for pain threshold (43.6 ± 3.1°C vs. 44.0 ± 3.1°C, p = 0.6) and tolerance (47.3 ± 1.5°C vs. 47.4 ± 1.6°C, p = 0.7). However, those with anxiety had significantly higher TSP than those without anxiety (6.0 ± 4.8 vs. 3.7 ± 3.9, p = 0.006), indicating greater central sensitization. CONCLUSIONS: Women with OAB and at least mild anxiety symptoms reported greater psychosocial burdens (i.e., psychological stress, stress reactivity, OAB-specific QOL) and somatic symptom severity and demonstrated greater central sensitization on QST than those without anxiety. These findings support the hypothesis that anxiety and psychological stress impact hypersensitivity mechanisms that may underlie and contribute to OAB, although further research is needed to better understand how and to what extent.

[Language, cultural adaptation and validation of the OABSS (Overactive Bladder Symptom Score) questionnaire in patients with overactive bladder].

AIM: To perform language and cultural adaptation and validation of the OABSS (Overactive Bladder Symptom Score) questionnaire among patients with overactive bladder (OAB), proposed as an effective tool for assessing the severity of symptoms and the efficiency of treatment in clinics of the Russian Federation. MATERIALS AND METHODS: In accordance with the protocols for carrying out such studies, the procedure of standardized forward-backward translation of the OABSS questionnaire was performed. Further, the intermediate Russian-language version was applied to 15 patients with subsequent correction of deficiencies and approval of the final Russian-language version of the questionnaire. In total, the study group included 176 patients of both sexes with OAB symptoms who filled out the questionnaire twice (test-retest) with an interval of 10-14 days. RESULTS: Based on the statistical analysis (Cronbach's alpha = 0.961), there was a significant degree of internal consistency of the sample. This fact is also supported by the very high retest reliability of the questionnaire (ICC >0.9). CONCLUSION: Our data showed that the Russian version of the OABSS questionnaire is a reliable and valid tool for subjective assessment of the severity of OAB symptoms.

Effects of Pelvic Floor Muscle Training on Sexual Dysfunction, Sexual Satisfaction of Partners, Urinary Symptoms, and Pelvic Floor Muscle Strength in Women With Overactive Bladder: A Randomized Controlled Study.

BACKGROUND: In women with overactive bladder (OAB), sexual dysfunctions and sexual satisfaction of their partners have been problems that are as important as urinary symptoms. AIM: To investigate the effects of pelvic floor muscle training (PFMT) on sexual dysfunction, sexual satisfaction of partners, urinary symptoms, and pelvic floor muscle strength (PFMS) in women with OAB. METHODS: Women with OAB were randomized into 2 groups: 6-week PFMT (n = 21) (home exercise program) and a control group (n = 22) (did not receive any treatment for OAB). OUTCOMES: Sexual dysfunction, sexual satisfaction of partner, urinary symptoms, and PFMS were assessed at baseline and after 6 weeks with the Female Sexual Function Index (FSFI), a Visual Analogue Scale (VAS), the OAB-Version8 (OAB-V8), and the Modified Oxford Scale (MOS), respectively. RESULTS: After 6 weeks, there was an increase in FSFI domains [desire (95% CI: 0.18 to 0.64; P:.001, d: 0.88); arousal (95% CI: 0.42 to 1.24, P:<.001, d: 1.17); orgasm (95% CI:0.85 to 1.47; P:<.001, d:1.89); satisfaction (95% CI: 0.85 to 1.44; P:<.001, d: 2.29); sexual pain (95% CI:0.80 to 1.52; P:<.001, d:1.47); total score (95% CI: 3.70 to 5.94; P:<.001, d: 2.55)], sexual satisfaction of partners (95% CI: 1.80 to 2.85; P:<.001, d:2.83) and PFMS scores (95% CI: 1.10 to 1.55; P:<.001, d:3.18), and a decrease in the OAB-V8 score (95% CI: -13.01 to -7.10; P:<.001, d:2.19) in the PFMT group compared to the control group. There was a significant decrease in sexual dysfunction in the PFMT group compared to the control group (P:.046). CLINICAL IMPLICATIONS: In order to improve sexual function, sexual satisfaction of the partners, urinary symptoms, and PFMS in women with OAB, PFMT should be added to the rehabilitation program in clinics. STRENGTHS & LIMITATIONS: The strength of this study was that it is a randomized controlled trial investigating the effect of PFMT in improving sexual function in OAB. The limitations of our study were the lack of a long-term (6 months-1 year) follow-up and the inability to blind. CONCLUSION: PFMT was effective in improving sexual dysfunction, sexual satisfaction of partners, urinary symptoms, and PFMS in women with OAB. Celenay ST, Karaaslan Y, Ozdemir E.

Overactive bladder (OAB): a failed concept needing revision to accommodate an external anatomical control system.

THESIS AND AIMS: In 45 years, the definitions and practice of the urodynamically based overactive bladder (OAB)/detrusor overactivity (DO) system have failed to adequately address pathogenesis and cure of urinary urge incontinence, frequency and nocturia. METHODS: We analysed the OAB syndrome with reference to the Integral Theory paradigm's (ITS) binary feedback system, where OAB in the female is viewed as a prematurely activated, but otherwise normal micturition caused mainly, but not entirely, by ligament damage/laxity. The ITS Clinical Assessment Pathway which details the relationships between structural damage (prolapse), ligaments and dysfunction (symptoms) is introduced. RESULTS: The ITS was able to "better explain" OAB pathophysiology in anatomical terms with reference to the binary model. The phasic patterns diagnostic of "detrusor overactivity" are explained as a struggle for control by the closure and micturition reflexes. The exponentially determined relationship between urethral diameter and flow explains why obstructive patterns occur, why they do not and why urine may leak with no recorded pressure. Mechanically supporting ligaments ("simulated operations") during urodynamic testing can improve low urethral pressure, negative pressure during coughing with SUI and diminish urge sensation or even DO patterns, transforming urodynamics from non-predictive test to accurate predictor of continence surgery results. High cure rates for OAB by daycare repair of damaged ligaments is a definitive test of the binary system's validity. CONCLUSION: Conceptual progression of OAB to the Integral Theory paradigms's prematurely activated micturition validates OAB component symptoms as a syndrome, explains pathogenesis, and unlocks a new way of understanding, diagnosing, treating and researching OAB.

Incidence and risk factors for postoperative urinary incontinence after various prostate enucleation procedures: systemic review and meta-analysis of PubMed literature from 2000 to 2021.

PURPOSE: To evaluate the risk of urinary incontinence (UI) after various prostate enucleation procedures (PEP). METHODS: PubMed was searched from January 2000 to July 2021 for studies investigating UI after PEP. The articles were divided into 5 subgroups: holmium, thulium, greenlight laser, electrocautery, and simple prostatectomy. Meta-analysis was performed to examine rate of stress (SUI), urge (UUI) or unspecified UI at short (< 3 months), intermediate (3-6 months), and long-term (> 6 months). The impact of age, prostate size, surgery time, laser time, postoperative nadir PSA level and technical modifications on UI was analyzed. RESULTS: Most (69.4%) of 49 articles included employed holmium laser. There was no significant difference in incidence of short-, intermediate-, and long-term UI, SUI and UUI between five sub-groups and within different technical modifications. Although not statistically significant, the incidence of UI was higher (15%) at short-term with green-light and simple prostatectomy (95% CI 9-23 and 1-84), and higher (4%) at intermediate-term with holmium laser (95% CI 2-8). SUI was more prevalent at short-term with holmium laser (4%; 95% CI 2-5%), and at intermediate term with simple prostatectomy (3%; 95% CI 1-14). UUI was higher in the thulium group (10%, 95% CI 7-16). Increased age, surgery time, laser time and prostate size up to 80 cc were associated with higher UI. There was no correlation between postoperative PSA and UI. CONCLUSIONS: There is no significant difference in incidence of UI, SUI and UUI after various PEP. Patients age, prostate size, surgery and laser time are linearly associated with UI.

Initial experience using the Axonics sacral neuromodulation system in patients with multiple sclerosis.

INTRODUCTION: Sacral neuromodulation (SNM) is third-line therapy approved for urge urinary incontinence (UUI) and urgency, and nonobstructive urinary retention. Multiple sclerosis (MS) patients often suffer from neurogenic lower urinary tract dysfunction (NLUTD). The utility of SNM in the MS population is limited by magnetic resonance imaging (MRI) incompatibility as routine MRIs to evaluate for disease progression are required. The Axonics System is the first Food and Drug Administration-approved SNM device that is 1.5/3 T full-body MRI-conditionally safe. This study seeks to investigate the symptomatic improvement in MS patients after implantation of the Axonics System. METHODS: All MS patients who elected for Axonics SNM from December 2019 to January 2021 were included. Demographics and scores were queried for urogenital distress inventory (UDI-6), incontinence impact questionnaire (IIQ-7), and global response assessment (GRA). RESULTS: Fifteen MS patients with UUI were included. The time to follow-up averaged 121 days. On UDI-6, 12 patients reported improvement, 1 worsening, and 2 no change. Average UDI-6 scores before and after implantation were 56.6 and 25.2 (p < 0.0001). Improvements were significant for all questions under stress urinary incontinence, UUI, and voiding difficulty subcategories. On IIQ-7, 14 patients reported improvement and 1 reported worsening. Average IIQ-7 scores before and after implantation were 59.0 and 22.2 (p < 0.001). Improvements were significant for travel, social, and emotional subcategories, but not for physical activity. The average GRA score was 6 ("moderately improved"). CONCLUSION: The majority of MS patients reported significant initial improvement in UUI and associated quality of life measures on validated questionnaires after implantation of the Axonics System. Future studies are needed to determine the long-term outcomes and durability of this MRI full-body conditionally-safe system.

Patient-tailored healthcare and tibial nerve neuromodulation in the treatment of patients with overactive bladder symptoms.

PURPOSE: The aim of this study was to demonstrate features predictive of treatment response for patient-tailored overactive bladder (OAB) intervention with an implantable tibial neurostimulator using patient and technical prediction factors. MATERIALS AND METHODS: This study was designed as a follow-up study based on parameter settings and patients' preferences during the pilot and extended study of the implantable tibial nerve stimulator (RENOVA™ iStim system). For this study, we compared all treatment parameters (stimulation amplitude, frequency, and pulse width) and usage data (duration of treatment) during the different follow-up visits. RESULTS: We obtained usage data from a total of 32 patients who were implanted with the system between February and September 2015. Age, sex, body mass index (BMI) and previous experience with percutaneous tibial nerve stimulation (PTNS) treatment were considered as possible prediction factors for treatment success. However, only BMI was considered a statistically significant prediction factor (p = 0.042). A statistically significant increase in mean treatment level was seen in the responder group during the 3 month follow-up visit (mean: 6.7 mA, SD 0.416) as compared with the initial system activation visit (mean: 5.8 mA, SD 0.400) (p = 0.049). No other visits demonstrated statistically significant changes in both groups (responders and nonresponders) during the defined timepoints. CONCLUSION: This data underscores the need to use patient-tailored OAB treatment. BMI was found to be a negative predictive factor for treatment success. However, it was not possible to develop a specific responder model. A model predicting response to treatment could be useful for implementing shared decision making.

Compensatory bladder behaviors ("coping") in women with overactive bladder.

AIMS: There is little information on how often or within what contexts individuals with OAB use compensatory behaviors ("coping") to manage symptoms. We sought to examine how frequently women with OAB report using coping behaviors and whether these are associated with psychosocial factors. METHODS: One hundred twenty adult women with OAB completed the OAB questionnaire (OAB-q), ICIQ-FLUTS questionnaire, PROMIS Anxiety and Depression, Perceived Stress Scale, patient perception of bladder condition, and demographic and clinical data. Responses from five items from the OAB-q Quality-of-Life scale asking about coping with OAB symptoms (i.e., "compensatory coping behaviors") were summed to generate a total Coping Score. Linear regression was used to identify associations between individual coping behaviors, total Coping Scores, and exposure variables. RESULTS: Most (88%) subjects reported using at least one compensatory coping behavior at least "a little of the time," with "locating the nearest restroom in a new place" the most frequent. Higher BMI, lower education, using OAB medication, and urgency incontinence as well as urinary symptom severity were all associated with higher coping scores. Beyond the influence of OAB severity, higher anxiety (ß = 0.15, 95% CI [0.05-0.26], p = 0.004) and stress (ß = 0.16 [0.03-0.25], p = 0.02) were significantly associated with higher total coping scores, although depression was not. CONCLUSIONS: Compensatory bladder behaviors (coping) were common in women with OAB and were associated with greater urinary symptom severity and higher anxiety and stress. Further study is needed to understand how coping behaviors and psychosocial factors relate, as these may represent important opportunities for interventions.

The effect of vitamin D deficiency and supplementation on urinary incontinence: scoping review.

INTRODUCTION AND HYPOTHESIS: Vitamin D receptors are found in skeletal and smooth muscle cells throughout the body, specifically in the bladder detrusor muscle. We reviewed the current literature on the association between vitamin D deficiency and urinary incontinence (UI), and whether vitamin D supplementation plays a role in the treatment of UI symptoms. METHODS: We performed a scoping review of all available studies. PubMed, Google Scholar, and PEDro databases were searched from inception until August 2020 with the keywords "urinary incontinence," "pelvic floor disorders," "lower urinary tract symptoms," "overactive bladder," and various terms for vitamin D. No language restrictions were imposed. The reference lists of all retrieved articles were also searched. RESULTS: The search revealed 12 studies of different research methodologies after elimination. In 6 out of the 7 cross-sectional studies reviewed, a significant association between vitamin D deficiency or insufficiency and the onset and severity of UI was found. In 2 out of the 3 prospective studies included, no association between vitamin D intake and UI was found; however, both randomized controlled trials that were reviewed found that vitamin D supplementation is effective for the treatment of UI. CONCLUSIONS: The existing literature supports an association between low levels of serum vitamin D and UI. Initial evidence regarding the effect of vitamin D supplementation on UI is accumulating, yet additional, comprehensive research is warranted to establish these findings.

Impact of intravesical onabotulinumtoxinA (Botox) on sexual function in patients with overactive bladder syndrome: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: The association between overactive bladder (OAB) syndrome and sexual dysfunction is well documented. Intra-detrusor onabotulinumtoxinA (Botox) has proven to be effective treatment for OAB syndrome. Our aim was to examine the impact of intravesical Botox injection on sexual function in patients with OAB, by systematically reviewing the literature. METHODS: We reviewed the literature for studies that reported a change in sexual function after Botox treatment in patients suffering from OAB. This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using pre-agreed keywords, from database inception to December 2020. Statistical analyses were performed using Review Manager (RevMan; v.5.4). RESULTS: Initial results yielded 455 citations. Seven articles met our inclusion criteria. One article was double-reported, leaving 6 studies in the systematic review. Three observational before-and-after studies used the Female Sexual Function Index (FSFI) with sufficient information, and therefore were included in our meta-analysis. The pooled number of participants in all studies was 119 patients. In the meta-analysis, there was significant improvement in the following domains of the FSFI after Botox injection; desire (mean difference (MD) -0.51, p = 0.02), arousal (MD -0.86, p = 0.02), lubrication (MD -0.57, p = 0.03), orgasm (MD -0.65, p = 0.0003) and satisfaction (MD -0.46, p = 0.05). Pain was the only domain that did not show improvement (MD -0.07, p = 0.79). The total FSFI score was reported in 88 patients (two studies) showing significant improvement (MD -0.77, p = 0.006). CONCLUSIONS: We report a systematic review of the effect of Botox treatment on sexual function in patients with OAB. Although studies are small, the results indicate a positive effect in patients with OAB.

Fluids affecting bladder urgency and lower urinary symptoms: results from a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: Caffeinated, alcoholic, artificially sweetened, carbonated, and acidic beverages are pervasive and consumed in large quantities. Reputedly, these beverages are "irritating to the bladder" and result in heightened void frequency, but prior studies lack control for intake volume. We tested the null hypothesis that women recruited from the community who demonstrate overactive bladder symptoms will show no difference by groups in void frequency when one group is instructed to replace listed beverages by substituting non-irritants (emphasis on water or milk) and the other group is instructed in healthy eating. METHODS: This was a parallel-group randomized controlled trial design with a three-period fixed sequence (baseline and 2 and 6 weeks post-baseline). We recruited 105 community women with overactive bladder symptoms. INCLUSION CRITERIA: >7 voids per day or 2 voids per night, daily intake of ≥16 oz. (473 ml) of beverages containing the ingredients listed above, and ≥ 32 oz. (946 ml) of total fluid intake. Stratified randomization was conducted. The primary outcome was average daily void frequency on a 3-day diary. RESULTS: Participants were 86% white, mean (SD) age was 46.6 (17.6) years, and baseline void frequency was 9.2 (2.9) voids per day. At 2 and 6 weeks, estimated average (SD) difference in void frequency between group 1 and group 2 was -0.46 (0.57) and -0.31 (0.57) voids per day (p > 0.05); the null hypothesis was not rejected. CONCLUSIONS: Women who reduce potentially irritating beverages while maintaining total fluid volume intake is not predictive of void frequency. Further research on type and volume of beverage intake is recommended.

Prevalence of urinary incontinence among young female adults.

A cross sectional survey was conducted in 2018-2019 to determine the prevalence of urinary incontinence among university going nulligravid young female adults in Rawalpindi/Islamabad, Pakistan. A total of 608 participants were included in the study via convenience sampling. Data was collected regarding demographic and personal information, in addition to Medical, Epidemiologic, and Social Aspects of Aging (MESA) Urinary Incontinence Questionnaire (UIQ). Independent t-test and One-way ANOVA were used for inter-group comparisons. Pearson and Spearman correlation was used to determine the relationship between variables. The overall prevalence of urinary incontinence was observed to be 193(31.7%) and of stress, urge and mixed incontinence was found to be 64(10.5%), 56(9.2%) and 73(12%) respectively. A significant difference (p<0.05) was observed in terms of MESA-UIQ stress incontinence and urge incontinence scores based on tobacco use, menstrual disorders, eating disorders and marital status.

Urethral function and failure: A review of current knowledge of urethral closure mechanisms, how they vary, and how they are affected by life events.

INTRODUCTION: A critical appraisal of the literature regarding female urethral function and dysfunction is needed in light of recent evidence showing the urethra's role in causing stress and urge urinary incontinence. METHODS: An evidence assessment was conducted using selected articles from the literature that contained mechanistic data on factors affecting urethral function and failure. RESULTS: Maximal urethral closure pressure (MUCP) is 40% lower in stress urinary incontinence (SUI) than normal controls. Evidence from five women shows relatively equal contributions to MUCP from striated/smooth muscle, vascular-plexus, connective tissue. MUCP varies twofold in individuals of similar age and declines 15% per decade even in nulliparous women. Age explains 57% of the variance in MUCP. This parallels with striated/smooth muscle loss and reduced nerve density. Factors influencing pressure variation minute-to-minute and decade-to-decade are poorly understood. Connective tissue changes have not been investigated. MUCP in de novo SUI persisting 9-months postpartum is 25% less than in age and parity-matched controls. Longitudinal studies do not show significant changes in urethral function after vaginal birth suggesting that changes in urethral support from birth may unmask pre-existing sphincter weakness and precipitate SUI. Mechanisms of interaction between support injury, pre-existing urethral weakness, and neuropathy are unclear. CONCLUSION: Urethral failure is the predominant cause of SUI and a contributing factor for UUI; potentially explaining why mixed symptoms predominate in epidemiological studies. Age-related striated muscle loss and differences between women of similar age are prominent features of poor urethral closure. Yet, connective tissue changes, vasculature function, and complex interactions among factors are poorly understood.

Effect of antibiotics on urine leakage in women with refractory detrusor overactivity: A phase IIb randomized trial.

AIM: Because bacterial cystitis is common in women with refractory detrusor overactivity, the aim was to compare the efficacy of 6 weeks of rotating antibiotics versus placebo, in conjunction with an anticholinergic, in controlling the symptoms of urge incontinence. METHODS: In a multicenter phase IIb double-blinded randomized placebo-controlled trial, women with urodynamically proven refractory detrusor overactivity were randomized in a 2:1 ratio of antibiotics versus placebo for 6 weeks, in addition to darifenacin for 6 months. Any woman with disabling cystitis symptoms was given appropriate antibiotics ("clinical override"). The primary outcome was the degree of urge incontinence change at 6 weeks and 6 months on 24-h pad test. Secondary outcomes were changes in leaks and voids per day measured on 3-day bladder diary and quality of life measures. Microbiological data were collected at all visits. RESULTS: Although 278 women were screened, only 36 were randomized and 33 (91.7%) completed the trial. Leakage on 24-h pad test decreased at 6 months by 75 g in patients receiving antibiotics versus 35 g in placebo. Cure of urge incontinence occurred at 6 months in 10/21 (48%) of antibiotics versus 2/12 (17%) of placebo. Clinical override, necessitating treatment of cystitis, occurred in 41.6% of placebo versus 16.7% of the antibiotic group by 6 months. CONCLUSION: Despite the small sample size, the study showed a significant reduction in pad leakage and leaks per day over 24 h in the active treatment group over a 6-month period. Nearly half of patients on placebo had disabling urinary tract infection symptoms that required clinical override treatment.

Randomized clinical trials assessing third-line therapies to treat non-neurogenic overactive bladder syndrome: a review about methodology.

INTRODUCTION AND HYPOTHESIS: Using similar methodologies and outcome measures is crucial to allow pertinent literature reviews and meta-analyses. Therefore, this scoping review aims to compare methodologies of randomized clinical trials (RCTs) assessing the efficacy of third-line therapies to treat non-neurogenic OAB: intradetrusor onabotulinumtoxinA (BoNTA) injections, sacral neuromodulation (SNM) and posterior tibial nerve stimulation (PTNS). METHODS: A literature search was conducted using the PubMed search database. Using filters, the search was limited to RCTs conducted on humans and written in English or French since 2000 which evaluated BoNTA injections, SNM and/or PTNS. RCTs focusing on pediatric or neurogenic OAB were excluded. For each included RCT, methodology was assessed using a standardized form investigating the study design, clinical outcomes and urodynamic outcomes. Inclusion criteria, sex ratio, blinding strategies, treatment arms, primary outcomes and delays for reevaluation were assessed. Availability of clinical and urodynamic outcomes was reported at baseline, 3 months and 6 months. RESULTS: Thirty-one RCTs were included in the final synthesis. The most frequent main outcome measure was change in the number of urinary incontinence episodes in 35.5% and in the number of voids per day in 25.8%. Bladder diaries were lacking in 12.9%, 32.3% and 80.1% at baseline, 3 and 6 months, respectively, while 26% of studies reported the results of urodynamic studies at any point. CONCLUSION: Heterogeneity in study designs and data collection was pointed out between RCTs assessing the efficacy of third-line therapies to treat non-neurogenic OAB. We therefore advocate for the development of specific research guidelines focusing on OAB-related therapies.

The Correlation between Severity of Overactive Bladder Symptoms with Female Sexual Dysfunction and Sexual Satisfaction of Partners.

PURPOSE: Sexual dysfunction in women with overactive bladder (OAB) syndrome has been an important topic, while the sexual satisfaction of partners has not been fully investigated. Our aim was to explore the association between the severity of OAB with female sexual dysfunction and sexual satisfaction of partners. METHODS: A total of 323 patients with OAB recruited in our hospital were included in our study from September 2017 to March 2019. Data were collected by Overactive Bladder Symptom Score (OABSS) questionnaire, self-designed questionnaire for basic characteristics; Female Sexual Function Index (FSFI); and sexual satisfaction survey for sex partners of patients. χ2 test or 1-way ANOVA was used to compare the variables among groups. Logistic regression analysis was performed to analyze the severity of OAB with female sexual dysfunction and sexual satisfaction of partners. The correlations between different OABSS domains with female sexual dysfunction and sexual satisfaction of partners were assessed. RESULTS: All the patients were classified into mild (n = 107), moderate (n = 98), severe (n = 118) OAB group based on OABSS. Most of the basic information were similar among groups, except for BMI, highest education, occupation, fertility, and history of pelvic floor surgery. After multiple factors correction, the severity of OAB, exercise frequency, and the history of pelvic floor surgery were statistically associated with the female sexual dysfunction and sexual satisfaction of partners. Urgency score was significantly correlated with female sexual dysfunction, and the urge incontinence was most significantly associated with the sexual satisfaction of partners. CONCLUSION: Severe OAB was closely associated with female sexual dysfunction and sexual satisfaction of partners. The urgency and urge incontinence should be focused for OAB management.
