Aims: Beyond causing physical discomfort, overactive bladder (OAB) is distressing to patients across a variety of psychosocial domains. In this qualitative component of a larger mixed methods study, we explore patients' lived experience with OAB to understand how this condition impacts individuals on a personal and social level, as well as their experiences interacting with the health care system.

Methods: A total of 20 patients and 12 physicians completed a questionnaire and semi-structured interview. The interview guide, developed in an iterative fashion by the authors, included questions about treatment decision making as well as experiences living with or treating OAB; this manuscript focuses on the questions probing lived experiences and interactions between patients and physicians. The interviews were recorded, transcribed and inductively coded and analyzed according to the principles of interpretive description to develop themes.

Results: Analysis of patient and physician interviews yielded five key themes: isolation due to OAB diagnosis, social stigma associated with noticeable OAB symptoms, embarrassment from interactions with the health care system, feeling invalidated and dismissed by physicians, and OAB patients as a "vulnerable" population with "desperation" for cure.

Conclusions: OAB causes patients marked distress beyond their physical symptoms; it causes feelings of isolation from friends and family and makes them feel embarrassed to discuss their condition with loved ones and physicians alike. Efforts to destigmatize OAB, validate patient experiences, and improve access to OAB care may help diminish the psychosocial burden of OAB.

Aims: Existing questionnaires provide limited information on the nature, severity and context surrounding lower urinary tract symptoms (LUTS) experienced during running, jogging and brisk walking. The aims of this study were to develop a theoretical model of the experience of LUTS by females participating in gait-based exercise activities and to use this model to generate a questionnaire to evaluate the presence, symptoms and bother associated with LUTS experienced by females during gait-based activities.

Methods: A theoretical model was developed through a review of the literature and refined through a focus group consultation including pelvic health physiotherapists, females who experienced leakage during exercise and academic researchers who studied female LUTS. A draft questionnaire was developed using key constructs identified in the model by the focus group. A new expert panel was recruited, which included physiotherapists, women with self-reported gait-induced LUTS and urogynecologists. This panel followed a DELPHI process to evaluate the relevance and completeness of the constructs within the questionnaire.

Results: Two rounds of consultation were required to reach consensus on the completeness of included constructs as well as the inclusion and wording of questions. The resulting questionnaire contains questions related to five key constructs: physical activity characteristics, symptoms of urgency, urgency urinary incontinence, stress urinary incontinence experienced during exercise and management/mitigation strategies adopted by respondents.

Conclusions: The content validity of the brisk walking- and running-induced lower urinary tracts symptoms questionnaire has been established. The next steps are to ensure that the questionnaire has adequate comprehensibility, followed by adequate measurement properties.

Aims: (1) To use intraoperative photographs to visualize and explain pudendal nerve compressions and anatomical variations of compression sites in patients with chronic pelvic pain. (2) To emphasize the diagnostic importance of sensory examination with a safety pin at the six pudendal nerve branches in all patients with chronic pelvic pain; the dorsal nerves (penis or clitoris; the perineal nerves; and the inferior rectal nerves).

Methods: Between 2003 and 2014, "definite" pudendal neuropathy was diagnosed by examination and with two neurophysiologic tests. Neurolysis, via a transgluteal approach, was recommended only after 14 weeks of conservative care failed to adequately improve symptoms and validated symptom scores. Photographs of surgical findings were culled for their educational impact. An illustration of each photo clarifies the surgical anatomy.

Results: The transgluteal incision permits access to pudendal anatomy and compression sites from the subpiriformis area through the interligamentary space and the pudendal canal (Alcock canal). Compressions were acquired or congenital and severity varied significantly. Pinprick sensory testing diagnoses pudendal neuropathy in 92% of both genders. Mid-nerve compression occurred commonly between the sacrotuberous and sacrospinous ligaments less frequently in the Alcock canal, but also at aberrant pathways, for example, between layers of the sacrotuberous ligament; a separate inferior rectal nerve passing through the sacrospinous ligament; at an anomalous lateral pathway posterior to the ischial spine. The results of international surgeons are discussed.

Conclusions: Decompression surgery was recommended in approximately 35% of patients in this practice, when pudendal neuropathy (pudendal syndrome), did not respond to two conservative levels of treatment: (1) nerve protection and medications and, (2) a series of three pudendal nerve perineural injections given at 4-week intervals. Significant nerve compression is consistently observed. Pathophysiology includes axonopathy from ischemia and demyelination. Neuropathy is readily diagnosed using a pinprick sensory examination of six pudendal nerve branches. Monitoring with the National Institutes of Health Chronic Prostatitis Symptom Index records cures >13 years.

Purpose: This investigation seeks to determine the triglyceride glucose (TyG) index's link to stress urinary incontinence (SUI) in American females of adult age.

Methods: The investigation relied on data acquired via the National Health and Nutrition Examination Survey (NHANES) conducted over the period from 2011 to 2018. The independent relationship between TyG index and SUI was tested using multivariate logistic regression analysis. We applied a smooth curve fitting approach to analyze the interrelation of them. In addition, subgroup analysis was conducted and interaction experiments were conducted.

Results: Among 4459 female participants aged 20 and above, TyG index and SUI demonstrated a favorable correlation. Model 3 indicated that with every single-unit rise in the TyG index, the incidence of SUI increases by 18% [1.18 (1.01, 1.38)]. In contrast to individuals in the lowest tertile, subjects within the highest tertile of the TyG index exhibited a 68% increase in SUI incidence [1.68 (95% CI: 1.26, 2.23), 0.0004]. By using smooth curve fitting, a nonlinear positive evidence of an interconnection of the TyG index to SUI was identified.

Conclusions: Women exhibiting increased TyG index levels are at a heightened risk of SUI. TyG index displays a stronger correlation than that observed with BMI. According to our findings, the TyG index is viewed as a potential tool for identifying SUI in women, and monitoring the value of TyG index may be helpful for predicting the occurrence of SUI.

Purpose: It has been proposed that reusable catheters are more cost effective and environmentally sustainable than single-use catheters intended for intermittent catheterization (IC). However, the aspect of individuals' well-being and preference for catheter type is not considered. In this study, we investigated the impact on individuals' health-related quality of life (HR-QoL) when testing a reusable catheter.

Materials and methods: The study was an open-labeled, single-arm, multicenter investigation with a treatment period of 28 days. Forty subjects using single-use hydrophilic catheters were accustomed to a reusable catheter for managing IC. HR-QoL was evaluated by the Intermittent-Self Catheterization Questionnaire (ISC-Q). Additionally, satisfaction was evaluated by the Intermittent Catheterization Satisfaction Questionnaire (InCaSa-Q). The difference in total score was analyzed using a mixed linear model. Furthermore, preference for IC (single-use vs. reusable) was assessed and microbial evaluation of the catheters was performed.

Results: The total ISC-Q score measuring HR-QoL decreased significantly by 28% (p < 0.001). Two of the four subdomains (ease-of-use and discreetness) also decreased significantly (p < 0.001). The total InCaSa-score and all four subdomains evaluating satisfaction decreased significantly (p < 0.005). The primary study results were supported by the fact that 90.9% of subjects preferred to use a single-use catheter for IC. Furthermore, 50% of reusable catheters were contaminated with bacteria.

Conclusion: Switching from single-use to reusable IC resulted in a significant decrease in HR-QoL and satisfaction. Moreover, the vast majority preferred the single-use catheter due to handling and convenience. The users' rights to their preferred bladder management method should be acknowledged.

Background: There is growing evidence of a possible correlation between depression and overactive bladder (OAB). However, few studies have classified depression according to its severity. Whether there is an association between different levels of depression and OAB symptoms remains unclear.

Methods: Participants with complete information about depression, OAB, and covariates in the National Health and Nutrition Examination Survey (NHANES) 2005-2018 were included in this study. Depression symptoms were assessed by the Patient Health Questionnaire-9. OAB symptoms were evaluated by the Overactive Bladder Symptom Score. Weighted multivariate logistic regression models were applied to analyze the relationship between depression and OAB.

Results: A total of 30 359 participants were included in this study, consisting of 6245 OAB patients and 24 114 non-OAB participants. The multivariate logistic regression suggested depression independently correlated with OAB (odds ratio [OR] = 2.764, 95% confidence interval [CI] = 2.429-3.146, p < 0.001). Further, mild (OR = 2.355, 95% CI = 2.111-2.627, p < 0.001), moderate (OR = 3.262, 95% CI = 2.770-3.841, p < 0.001), and moderately severe to severe depression (OR = 3.927, 95% CI = 3.246-4.752, p < 0.001) were all associated with OAB. Additionally, depression was also correlated with urgency urinary incontinence (OR = 2.249, 95% CI = 1.986-2.548, p < 0.001) and nocturia (OR = 2.166, 95% CI = 1.919-2.446, p < 0.001).

Conclusion: This study indicated different levels of depression, even mild depression, were independent risk factors for OAB. Given the frequent coexistence and potential interactions between depression and OAB, clinicians should be aware of the importance of assessing both physical and psychological symptoms in these patients. Early diagnosis and holistic treatment may improve the treatment outcomes, particularly for those suffering from both conditions.

Purpose: Diabetic bladder dysfunction (DBD) is the most common diabetic complication. Logically, regulation of blood glucose should reverse dysfunction, but the Epidemiology of Diabetes Interventions and Complications study found strict control ineffective. However, it is possible that strict control may prevent DBD if initiated before symptoms appear. We examine the effect of early glucose control on development of DBD in the female diabetic Akita mouse (Type 1) and test the potential of inhibiting/deleting NLRP3 as adjunct therapy to glucose control.

Materials and methods: Female Akita mice were bred NLRP3^+/+ or NLRP3^-/-. At 6 weeks of age, diabetics received either no glucose control or insulin pellets (s.c., Linshin) designed to poorly or strictly control blood glucose. At Week 15, blood glucose (glucometer), the extravasation potential of bladder (an indirect measurement of inflammation) and bladder function (urodynamics) were assessed.

Results: Blood glucose of diabetics was reduced in poorly controlled and strongly reduced in strictly controlled groups. Levels were not affected by deletion of NLRP3. Evans blue dye extravasation correlated with glucose control and was eliminated in the NLRP3^-/- groups. Urodynamics found markers of overactivity in diabetics which was improved in the poorly controlled group and eliminated in the strictly controlled group. In the NLRP3^-/- mice, no bladder dysfunction developed, regardless of glucose control.

Conclusions: Early-initiated strict glycemic control and NLRP3 elimination can effectively prevent DBD, suggesting hyperglycemia acts through NLRP3-induced inflammation to trigger DBD.

Purpose: The purpose of this guideline is to provide evidence-based guidance to clinicians of all specialties on the evaluation, management, and treatment of idiopathic overactive bladder (OAB). The guideline informs the reader on valid diagnostic processes and provides an approach to selecting treatment options for patients with OAB through the shared decision-making process, which will maximize symptom control and quality of life, while minimizing adverse events and burden of disease.

Methods: An electronic search employing OVID was used to systematically search the MEDLINE and EMBASE databases, as well as the Cochrane Library, for systematic reviews and primary studies evaluating diagnosis and treatment of OAB from January 2013 to November 2023. Criteria for inclusion and exclusion of studies were based on the Key Questions and the populations, interventions, comparators, outcomes, timing, types of studies and settings (PICOTS) of interest. Following the study selection process, 159 studies were included and were used to inform evidence-based recommendation statements.

Results: This guideline produced 33 statements that cover the evaluation and diagnosis of the patient with symptoms suggestive of OAB; the treatment options for patients with OAB, including Noninvasive therapies, pharmacotherapy, minimally invasive therapies, invasive therapies, and indwelling catheters; and the management of patients with BPH and OAB.

Conclusion: Once the diagnosis of OAB is made, the clinician and the patient with OAB have a variety of treatment options to choose from and should, through shared decision-making, formulate a personalized treatment approach taking into account evidence-based recommendations as well as patient values and preferences.

Background: Many genitourinary tract disorders could be attributed partly to the microbiota. This study sought to conduct a systematic review of the role of the microbiota in urinary chronic pelvic pain syndrome (UCPPS).

Methods: We searched Embase, Scopus, Web of Science, and PubMed with no time, language, or study type restrictions until December 1, 2023. The JBI Appraisal Tool was used to assess the quality of the studies. Study selection followed the PRISMA statement. Studies addressing microbiome variations among patients suffering from interstitial cystitis/bladder pain syndrome (IC/BPS) or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and a control group were considered eligible.

Results: A total of 21 studies (1 UCPPS, 12 IC/BPS, and 8 CP/CPPS) comprising 1125 patients were enrolled in our final data synthesis. It has been shown that the reduced diversity and discrepant composition of the gut microbiota may partly be attributed to the UCPPS pathogenesis. In terms of urine microbiota, some operational taxonomic units were shown to be elevated, while others became less abundant. Furthermore, various bacteria and fungi are linked to specific clinical features. Few investigations denied UCPPS as a dysbiotic condition.

Conclusions: Urinary and intestinal microbiota appear to be linked with UCPPS, comprising IC/BPS and CP/CPPS. However, given the substantial disparity of published studies, a battery of prospective trials is required to corroborate these findings.
