Association between overactive bladder and depression in American adults: A cross-sectional study from NHANES 2005–2018

Background and aimOveractive bladder (OAB) and depression are both common disorders and there is research suggesting an association between the two, but there is a lack of studies with large samples. The aim of this study is to investigate the association between OAB and depressive symptoms. MethodsWe used data from the National Health and Nutrition Examination Survey (NHANES) database for the period 2005 to 2018. OAB was characterized by the Overactive Bladder Symptom Score (OABSS, score > 3) and depression was diagnosed by the Patient Health Questionnaire (PHQ-9, score ≥ 10). There were three models employed in our analysis: (1) Crude model was unadjusted; (2) Model 1 was adjusted for age, sex, race/ethnicity, educational level, and marital status; (3) Model 2 was adjusted for factors in Model 1 plus the remained potential covariates. We used survey-weighted logistic regression models to assess the association between OAB and depression. Subsequently, subgroup analyses and smoothed curve analyses were used to evaluate the reliability of the findings. ResultsFinally, a total of 6612 participants were included in our study, consisting of 1005 participants with diagnosis of OAB and 5607 participants without diagnosis of OAB. After adjusting for all covariates, there was a significant positive association between OAB and depression (OR: 2.89, 95 % CI: 1.91, 4.37). The severity of OAB was also positively associated with depression. Compared to participants without OAB, the fully adjusted ORs for depression were 2.76 (95 % CI: 1.64, 4.65) for those with mild OAB, 3.79 (95 % CI: 1.68, 8.55) for those with moderate OAB, and 5.21 (95 % CI: 1.39, 19.53) for those with severe OAB. ConclusionsThis study revealed a strong association between OAB and depression and a progressive increase in the risk of depression as the severity of OAB (mild, moderate, and severe) increased. Therefore, it is important for clinicians to recognize the assessment of OAB symptoms in patients who are at risk for or have developed depressive symptoms, as well as the mental health of patients with OAB.

The association between wet overactive bladder and consumption of tea, coffee, and caffeine: Results from 2005–2018 National Health and Nutrition Examination Survey

Background & aimsPrevious studies have reported an inconsistent relationship between overactive bladder (OAB) and the consumption of tea, coffee, and caffeine. Our study aims to determine these associations in a large and nationally representative adult sample. MethodsThis cross-sectional study included 15,379 participants from the 2005-2018 US National Health and Nutrition Examination Survey (NHANES) database. The outcome was the risk of wet OAB that was diagnosed when the OAB symptom score was ≥3 with urgent urinary incontinence and excluded other diseases affecting diagnosis. The exposures were the consumption of tea, coffee, and caffeine. Weighted logistic regression models were established to explore these associations by calculating odds ratios (OR) and 95% confidence intervals (CI), as did restricted cubic splines (RCS) used to analyze the nonlinear associations. ResultOf all the participants (n = 15,379), 2207 had wet OAB. Mean [SE] consumption of tea, total coffee, caffeinated coffee, decaffeinated coffee, and caffeine was 233.6 [15.7] g/day, 364.3 [15.5] g/day, 301.6 [14.9] g/day, 62.7 [7.9] g/day, 175.5 [6.6] mg/day in participants with wet OAB, respectively. In the fully adjusted model, compared to those without tea consumption, the high consumption of tea (>481 g/day) was associated with an increased risk of wet OAB (OR: 1.29; 95%CI: 1.01-1.64). Low decaffeinated coffee (0.001-177.6 g/day) had a negative association with the risk (OR: 0.66; 95%CI: 0.49-0.90). In the RCS analysis, tea consumption showed a positive linear association with the risk of wet OAB, and decaffeinated coffee showed a nonlinear relationship with the risk and had a turning point of 78 g/day in the U-shaped curve between 0-285 g/day. Besides, total coffee, caffeinated coffee, and caffeine consumption had no significant association with the risk. Interestingly, in the high tea consumption, participants with high total coffee consumption [>527.35 g/day, OR and 95%CI: 2.14(1.16-3.94)] and low caffeine consumption [0.1-74.0 mg/day, OR and 95%CI: 1.50(1.03-2.17)] were positively associated with the risk of wet OAB. ConclusionHigh tea consumption was associated with the increased risk of wet OAB, especially intake together with high total coffee and low caffeine consumption, but no significant association with the single consumption of total coffee and caffeine. Low decaffeinated coffee was associated with a decreased risk of wet OAB. It is necessary to control tea intake when managing the liquid intake of wet OAB patients.

Long-term survival and functional outcomes of laparoscopic surgery for clinical stage I ultra-low rectal cancers located within 5 cm of the anal verge: A prospective phase II trial (Ultimate trial).

To clarify the long-term oncological outcomes and postoperative anal, urinary, and sexual functions after laparoscopic surgery for clinical stage I very low rectal carcinoma located near the anal canal. Laparoscopic surgery is widely applied for rectal cancer; however, concerns remain, with some studies showing poorer outcomes compared to open surgery. This single-arm, phase II trial included patients registered preoperatively from 47 institutions in Japan. The planned sample size was 300. The primary endpoint was the 3-year local recurrence rate. Anal, urinary, and sexual functions were evaluated using a prospective questionnaire. Three-hundred patients were registered between January 2014 and March 2017. Anus-preserving surgery was performed in 278 (93%), including 172 who underwent intersphincteric resection (58%) and 106 (36%) who underwent low anterior resection. The 3-year cumulative local recurrence rate was 6.3%. At 3 years postoperatively, 87% of patients used their own anus, and the median incontinence score improved from 12 at 3 months to 8 at 3 years. Only 5% of patients had severe incontinence (incontinence score of 16 points). Postoperative urinary function evaluation showed that International Prostate Symptom Score and Overactive Bladder Symptom Score decreased 1 week after surgery, but recovered to preoperative level 1 month after surgery. International Consultation on Incontinence Questionnaire-Sort Form remained almost stable after surgery. Sexual function evaluation using the International Index of Erectile Function-5 and International Index of Erectile Function-15 revealed that the patients had deteriorated 3 months after surgery but had recovered only slightly by 6 months. Laparoscopic surgery achieves feasible long-term oncological outcomes and a high rate of anus preservation with moderate anal function, and an acceptable incontinence score. While urinary function recovered rapidly, sexual function showed poor recovery.

Efficacy and Safety of Low-Dose Intravesical OnabotulinumtoxinA Injections in Female Patients With Detrusor Overactivity With Detrusor Underactivity.

We assessed the effectiveness and safety of using intravesical onabotulinumtoxinA (onabotA; BOTOX) injection with a low dose (75 units) for treating urinary storage symptoms in patients with detrusor overactivity with detrusor underactivity (DODU) compared to using the standard 100 units of onabotA in patients with overactive bladder (OAB). This ambidirectional study included 121 female patients who received intravesical onabotA injections at our hospitals. A total of 87 patients with OAB and 34 patients with DODU were reviewed using a 3-day voiding diary, uroflowmetry, and questionnaires including the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score, and Patient Perception of Bladder Condition. Patients were evaluated at baseline, within 2 weeks of treatment, and beyond 3 months after treatment. Questionnaire scores of the DODU group demonstrated significant improvement in the short term, with a subsequent decline, but an overall improvement compared to baseline in the long term. Notably, the DODU group exhibited enhanced IPSS voiding scores after the treatment. In the OAB group, most questionnaire scores, excluding the IPSS voiding score, showed significant posttreatment improvement, which was sustained to some extent in the long term. Voiding diary parameters related to storage symptoms were enhanced in both groups. The maximum and mean flow rates decreased in the OAB group but increased in the DODU group, particularly in the short term (P=0.000). The postvoid residual volume increased in both groups after posttreatment, with a mitigated change in the long term. Safety assessments revealed manageable adverse events in both groups with comparable frequencies. Low-dose intravesical onabotA for DODU demonstrated a relatively shorter duration of efficacy than OAB. Nonetheless, the treatment improved both storage and voiding symptoms in patients with DODU without significant adverse effects.

A randomized controlled trial evaluating low-intensity shockwave therapy for treatment of persistent storage symptoms following transurethral surgery for benign prostatic obstruction.

Low-intensity shockwave therapy (Li-SWT) can improve bladder function through enhancement of angiogenesis and nerve regeneration and suppression of inflammation and overactivity. In this trial, we aimed to evaluate the efficacy of Li-SWT on persistent storage symptoms after transurethral surgery (TUS) for benign prostatic obstruction (BPO). Between July 2020 and July 2022, 137 patients with persistent storage symptoms; urgency episodes/24 h ≥ 1 and daytime frequency ≥8, for at least three months after TUS for BPO were randomly allocated to Li-SWT versus sham versus solifenacin 10 mg/day in 3:1:1 ratio. The primary end point was the percent reduction from baseline in overactive bladder symptom score (OABSS) at 3-month follow-up. The changes in 3-day voiding diary parameters, quality of life (QoL) score, peak flow rate and residual urine at 3 and 6-month follow-up were compared. Treatment-related adverse effects were also evaluated. Baseline data were comparable between groups. The percent reduction from baseline in OABSS at 3-month follow-up was significantly higher in Li-SWT compared to sham (-55% versus -11%), and it was comparable between Li-SWT and solifenacin-10 (-55% versus -60%). Li-SWT achieved significant improvement like solifenacin-10 in 3-day voiding diary parameters and QoL score at 3-month follow-up. This improvement remained comparable between Li-SWT and solifenacin-10 at 6-month follow-up. No adverse effects related to Li-SWT were noted apart from tolerable pain during the procedure. Solifenacin-10 was associated with bothersome adverse effects in 73% of the patients with 11.5% discontinuation rate. Li-SWT ameliorates persistent storage symptoms and promotes QoL after TUS for BPO, with comparable efficacy and better tolerance compared to solifenacin.

Efficacy of Transvaginal Surgery Using an ORIHIME Mesh With Wider Arms and Adjusted Length.

Transvaginal mesh surgery (TVM) is an effective treatment measure for pelvic organ prolapse (POP). However, the ORIHIME mesh (Kono Seisakusho, Japan, Tokyo), which has the disadvantage of poor adherence to tissues, is currently the only productavailable for this procedure. Our research team has previously developed a modified ORIHIME meshwith wider arms with the aim of minimizing the risk of POP recurrence. Additionally, the length of the mesh behind the anterior vaginal wall has been adjusted to prevent urinary incontinence. The current study aims to examine the efficacy of this modified mesh in minimizing postoperative complications in patients undergoing uphold-type TVM. The data of 84 patients who underwent TVM using ORIHIME at our hospital since July 2019 were retrospectively analyzed. The patients were divided into three groups as follows: (a) normal arms (NA; arm width < 6 cm; n = 29 cases); (b) wide arms without length adjustment (WA and LA (-); arm width > 6 cm; n = 27 cases); and (c) wide arms with length adjustment (WA and LA (+); n = 28 cases). Data were collected using various questionnaires, and the residual urine volume was measured before and after surgery. Additionally, the 60-minute pad test was performed where possible, and the recurrence and complication rates were recorded. The incidence of mesh exposure and urinary incontinence in daily life tended to be lower in the WA and LA (+) groups, although this difference was not statistically significant. The one-year postoperative POP recurrence rate, residual urine volume, International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score were significantly lower in the WA and LA (+) groups compared to the other groups. Uphold-type TVM using the modified ORIHIME mesh with wider arms and adjusted length was associated with better postoperative treatment outcomes compared to TVM using the traditional ORIHIME mesh.

Effect of detrusor underactivity on surgical outcomes of holmium laser enucleation of the prostate.

To evaluate the effect of detrusor underactivity (DUA) on the postoperative outcomes of holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia (BPH). Patients with BPH who underwent HoLEP between January 2018 and December 2022 were enrolled in this prospective database study. Patients were divided into DUA (bladder contractility index [BCI] <100) and non-DUA (BCI ≥100) groups. Objective (maximum urinary flow rate [Qmax], post-void residual urine volume [PVR]) and subjective outcomes (International Prostate Symptom Score [IPSS], Overactive Bladder Symptom Score [OABSS], satisfaction with treatment question [STQ], overall response assessment [ORA], and willingness to undergo surgery question [WUSQ]) were compared between the two groups before surgery, and at 3 and 6 months after HoLEP. A total of 689 patients, with a mean (standard deviation [SD]) age of 69.8 (7.1) years, were enrolled. The mean (SD) BCI in the non-DUA (325 [47.2%]) and DUA (364 [52.8%]) groups was 123.4 (21.4) and 78.6 (14.2), respectively. Both objective (Qmax and PVR) and subjective (IPSS, IPSS-quality of life, and OABSS) outcomes after surgery significantly improved in both groups. The Qmax was lower in the DUA than in the non-DUA group postoperatively. At 6 months postoperatively, the total IPSS was higher in the DUA than in the non-DUA group. There were no significant differences in surgical complications between the two groups. Responses to the STQ, ORA, and WUSQ at 6 months postoperatively demonstrated that the patients were satisfied with the surgery (90.5% in the DUA group; 95.2% in the non-DUA group), their symptoms improved with surgery (95.9% in the DUA group; 100.0% in the non-DUA group), and they were willing to undergo surgery again (95.9% in the DUA group; 97.9% in the non-DUA group). There were no significant differences in the responses to the STQ and WUSQ between the two groups. Our midterm results demonstrated that patients with BPH and DUA showed minimal differences in clinical outcomes after HoLEP compared to those without DUA. The overall satisfaction was high in the DUA group.

Multicomponent Intervention for Overactive Bladder in Women

Although the cognitive components of behavioral therapy for overactive bladder (OAB) are widely recognized, there is a lack of studies evaluating the effectiveness of multicomponent interventions that include cognitive components as a treatment for OAB. To examine the efficacy of a multicomponent intervention in improving health-related quality of life (HRQOL) for women with moderate to severe OAB. This multicenter, open-label, randomized clinical trial was conducted in Japan among women aged 20 to 80 years who had moderate to severe OAB. Participants were recruited from 4 institutions between January 16, 2020, and December 31, 2022, through self-referral via advertisement or referral from the participating institutions. Participants were randomized 1:1 by minimization algorithm using an internet-based central cloud system to four 30-minute weekly sessions of a multicomponent intervention or waiting list. Both groups continued to receive baseline treatment throughout the study period. The primary outcome was the least-squares mean changes from baseline through week 13 in HRQOL total scores of the OAB questionnaire between 2 groups. Secondary outcomes included OAB symptom score and frequency volume chart. A total of 79 women were randomized to either the intervention group (39 participants; mean [SD] age, 63.5 [14.6] years) or the waiting list control group (40 participants; mean [SD] age, 63.5 [12.9] years). One participant from each group dropped out from the allocated intervention, while 5 participants in the intervention group and 2 in the control group dropped out from the primary outcome assessment at week 13. Thirty-six participants (92.3%) in the intervention group and 35 (87.5%) in the control group had moderate OAB. The change in HRQOL total score from baseline to week 13 was 23.9 points (95% CI, 18.4-29.5 points) in the intervention group and 11.3 points (95% CI, 6.2-16.4 points) in the waiting list group, a significant difference of 12.6 points (95% CI, 6.6-18.6 points; P < .001). Similar superiority of the intervention was confirmed for frequency of micturition and urgency but not for OAB symptom score. These findings demonstrate that a multicomponent intervention improves HRQOL for women with moderate to severe OAB and suggest that the cognitive component may be an effective treatment option for women with OAB.

Unraveling the interplay between dyskinesia and overactive bladder symptoms in Parkinson’s disease: a comprehensive cohort study based on the long-term follow-up database of Parkinson’s disease

ObjectivesOveractive bladder (OAB) and dyskinesia are frequent complications in patients with Parkinson’s disease (PD). However, the correlation between OAB and dyskinesia has been insufficiently explored. The purpose of this study was to examine the relationship between dyskinesia, OAB, and clinical characteristics among individuals with PD.Methods1338 PD patients were included in the present study. Demographic features were compared between patients with or without dyskinesia and OAB symptoms. Logistic regression was conducted on dyskinesia to screen clinically relevant factors. Overactive Bladder Symptom Score (OABSS) was further used to stratify the association between the severity of OAB and the occurrence of dyskinesia.ResultsThis study indicates that both dyskinesia and OAB are significantly related to disease severity and cognitive status. PD patients with dyskinesia and OAB having higher UPDRS scores (p < 0.001), H-Y scores (p < 0.001), NMSQ (p < 0.001) and MoCA scores (p < 0.001), and lower MMSE scores (p < 0.001) are identified. The multivariate logistic regression confirms that disease duration (p = 0.041), LEDD (p < 0.001), UPDRSII (p < 0.001), MoCA (p = 0.024), urgency (p < 0.001), frequency (p < 0.001), and nocturia (p = 0.002) are independent risk factors for dyskinesia. Trend analysis indicates that the risk of dyskinesia significantly increases when patients exhibit moderate to severe OAB symptoms (OABSS > 5) (p < 0.001). No significant interactions were found between OABSS and age, gender, disease duration, LEDD, and NMSQ scores in different subgroups, indicating that dyskinesia is more pronounced in patients with OABSS > 5.DiscussionThis study provides compelling evidence supporting the strong correlation between OAB and dyskinesia in PD patients, emphasizing the presence of shared pathogenic mechanisms between these two conditions. Our findings underscore the importance of considering both OAB and dyskinesia in the clinical management of PD, investigating the intricate connections between OAB and dyskinesia could unveil valuable insights into the complex pathophysiology of PD and potentially identify novel therapeutic targets for more effective PD treatment strategies.

Efficacy and safety of tibial nerve stimulation using a wearable device for overactive bladder.

To evaluate the efficacy and safety of a wearable, smartphone-controlled, rechargeable transcutaneous tibial nerve stimulation (TTNS) device in patients with overactive bladder (OAB). This multicentre, prospective, single-blind, randomised clinical trial included eligible patients with OAB symptoms who were randomly assigned to the stimulation group or sham group. The primary efficacy outcome was change from baseline in voiding frequency/24 h after 4 weeks of treatment. The secondary efficacy outcomes included changes in bladder diary outcomes (urgency score/void, nocturia episodes/day, micturition volume/void, and incontinence episodes/day), questionnaires on Overactive Bladder Symptom Score (OABSS), Patient Perception of Bladder Condition (PPBC), and American Urological Association Symptom Index Quality of Life Score (AUA-SI-QoL) at baseline and after 4 weeks of treatment. Device-related adverse events (AEs) were also evaluated. In the full analysis set (FAS), the mean (sd) change of voiding frequency/24 h in the stimulation group and sham group at 4 weeks were -3.5 (2.9) and -0.6 (2.4), respectively (P < 0.01). Similar results were obtained in the per-protocol set (PPS): -3.5 (2.9) vs -0.4 (2.3) (P < 0.01). In the FAS and PPS, micturition volume/void significantly improved at 4 weeks (P = 0.01 and P = 0.02). PPBC improvement almost reached significance in the FAS (P = 0.05), while it was significant in the PPS (P = 0.02). In the FAS and PPS, AUA-SI-QoL significantly improved at 4 weeks in the two groups (P < 0.01 and P < 0.01), whereas there were no significant differences in urgency score/void, nocturia episodes/day or OABSS between the groups. Also, no device-related serious AEs were reported. The non-invasive neuromodulation technique using the novel ambulatory TTNS device is effective and safe for treating OAB. Its convenience and easy maintenance make it a new potential home-based treatment modality. Future studies are warranted to confirm its longer-term efficacy.

Evaluating the Practicality of Causal Inference From Non-randomized Observational Data in Small-Scale Clinical Settings: A Study on the Effects of Ninjin'yoeito.

Objective The primary goal of this study was to demonstrate the practical application of causal inference using non-randomized observational data, adapting this approach to smaller populations, such as those in hospitals or community healthcare. This adaptation seeks a more effective and practical research method than randomized controlled trials (RCTs), with the goal of revealing novel insights unexplored by traditional research and enhancing understanding within the realm of causal inference. Methods This study evaluated the effects of Ninjin'yoeito (NYT), a traditional Japanese Kampo medicine, on Overactive Bladder Symptom Score (OABSS) and the frailty scores. Employing new statistical methods, this study sought to illustrate the efficacy of estimating causal relationships from non-randomized data in a clinical setting. The database included 985 women aged 65-90 years who visited a clinic between November 2016 and November 2022. By utilizing various statistical techniques, including regression analysis, inverse probability of treatment weighting (IPTW), instrumental variable (IV), and difference-in-differences (DiD) analysis, this study aimed to provide insights beyond traditional methods, attempting to bridge the gap between theory and practice in causal inference. Results After applying propensity score matching, the NYT treatment group (220 participants) and non-treatment group (182 participants) were each adjusted to two groups of 159 individuals. NYT significantly improved OABSSand frailty scores. IPTW analysis highlighted that on average, the NYT treatment group showed an improvement of 0.8671 points in OABSS and 0.1339 points in the frailty scores, surpassing the non-treatment group (p<0.05). IV analysis indicated that NYT treatment is predicted to increase ΔOABSS by an average of approximately 4.86 points, highlighting its significant positive impact on OABSS improvement. The DiD analysis showed that the NYT treatment group demonstrated an average improvement of 0.5457 points in OABSS, which was significantly higher than that of the control group.The adjusted R² value for the model is 0.025. Conclusion This study successfully implemented a practical application of causal inference using non-randomized observational data in a relatively small population. NYT showed a significant improvement in OABSS and vulnerability, and this result was confirmed using a new statistical method. The relatively low adjusted R² of the model suggests the existence of other unmeasured variables that influence OABSS and vulnerability improvement. In particular, the use of diverse statistical techniques, including IPTW, IV, and DiD analysis, is an important step toward revealing the effectiveness of inferring causal relationships from non-randomized data and narrowing the gap between theory and practice. This study provides a valid and practical alternative to RCTs and reveals new insights that have not been explored in traditional research.

(051) Urodynamic Profiles of Young Aged Women with Genital Pain Disorder

Abstract Introduction It is not uncommon in young female patients with genital pain disorder, they also complain urethral discomfort or unusual sensitivity, bothering symptoms on their urethra and genital area with LUTS. Although urodynamic studies or pressure flow studies are one of very optional studies of diagnostic steps, pressure flow studies provide detailed information of patient bladder-urethral synergistic function that may contribute proper function of the pelvic floor and related organs. However, studies are limited providing their relationship between urethral functional status and etiology of pain. Objective In this study, we aimed to evaluate female patients pressure flow profiles, urethral pressure profiles (UPP) in particular and to investigate their correlation of clinical symptoms in terms of genital pain disorder in 20’s-30’s aged young female. Methods Data of 30 female patients age between 20–39 years old with genital pain and LUTS for more than 6 months were retrospectively analyzed. Pressure flow study (PFS) with free uroflowmetry, overactive bladder symptom score (OABSS), visual analogue scale (VAS), female sexual function index (FSFI) were retrospectively analyzed according to aged groups of 20’s and 30’s. Data were statistically analyzed using t-test (p&amp;lt;0.05). Results We divided the subject patients into 2 groups; age of 20’s (n=16, 20–28, median 25 years old) and age of 30’s (n=14, 30–39, median 34 years old). Average MUCP of all patients was 104 cmH2O. In the group of aged 20’s, mean MUCP was 98.75 cmH2O, mean VAS was 5.81; in the group of aged 30’s, mean MUCP was 111.07 cmH2O, mean VAS was 5.57, respectively. All of the data showed high pressure of MUCP in PFS, &amp;gt;60 cmH2O. In group of 30’s, all the parameters of PFS showed higher compared with 20’s. Mean OAB symptom scores (OABSS) showed 3.63 (20’s) and 3.07 (30’s) respectively (p&amp;gt;0.05) Conclusions Urethral pressure, PdetQmax and Qmax showed significantly high in young females with genital pain. This study suggests that increased urethral tone or resistance may contribute to urethral/genital pain. Proper evaluation of urethral pressure profile and pelvic floor tone would be helpful to provide optimal management of genital pain disorder. Disclosure No.

Treatment Patterns with Mirabegron and Antimuscarinics for Overactive Bladder: A Prospective, Registry Study in Taiwan and South Korea (FAITH).

This study aimed to assess overactive bladder (OAB) treatment patterns and factors associated with effectiveness and persistence. A prospective, longitudinal, observational registry study of adults starting OAB therapy with mirabegron or antimuscarinics was undertaken. Primary endpoints were time from treatment initiation to discontinuation/switching; proportion who discontinued/switched; and reasons for discontinuation/switching. Secondary endpoints included OAB Symptom Score (OABSS), OAB Questionnaire: Short Form, and OAB Bladder Assessment Tool scores; factors associated with effectiveness and persistence; and safety. In total, 556 patients initiating mirabegron and 250 initiating antimuscarinics were enrolled. There was no treatment switch, change, or discontinuation in 68.5% of the mirabegron initiator group and median time to treatment change was not reached. Mean initial treatment duration was 130.8days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, and patients with mild and moderate OAB had significantly better persistence with mirabegron than those with severe OAB. Urinary tract infection was the most common adverse event with mirabegron. There was no treatment switch, change, or discontinuation in 60.4% of the antimuscarinics initiator group and median time to treatment change was not reached. Solifenacin was the most frequent initial treatment (66.0%). Mean treatment duration was 122.2days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, while patients with OAB medication in the 12months before enrollment had significantly better persistence with antimuscarinics than those with no previous OAB medication. Dry mouth was the most common adverse event with antimuscarinics. Mirabegron and solifenacin were commonly prescribed as first-line OAB medications. There was no treatment switch, change, or discontinuation in more than 60% of the mirabegron initiator and antimuscarinics initiator groups. Mean initial treatment duration was 130.8days and 122.2days for mirabegron and antimuscarinics, respectively. Graphical Abstract available for this article. ClinicalTrials.gov NCT03572231.

Objectives: The purpose of this study is to report a case of Korean medicine treatment accompaning myofascial trigger-point accupuncture for severe &amp; persistent lower urinary tract symptoms after radical prostatectomy.Materials and Methods: A prostate cancer patient with severe &amp; persistent lower urinary tract symptoms after radical prostatectomy conducted 26 months ago, was treated with Korean medicine accompaning myofascial trigger-point accupuncture. The International Prostate Symptom Score(IPSS), the IPSS Quality of Life(IPSS-QoL) and the Overactive Bladder Symptom Score(OABSS) questionaires were administered to evaluate the effect of treatment for lower urinary tract symptoms.Results: After 5 month treatment with Korean medicine accompaning myofascial trigger-point accupuncture, IPSS, IPSS-QoL and OABSS progressed from 28 to 8, from 5 to 2 and from 12 to 4 respectively.Conclusion: This case study suggests that Korean medicine accompaning myofascial trigger-point accupuncture may contribute to treat severe &amp; persistent lower urinary tract symptoms after radical prostatectomy.

Efficacy and sex-specific outcomes after six episodes of percutaneous tibial nerve stimulation treatment on overactive bladder syndrome symptoms

ObjectiveThis study aimed to investigate the efficacy of six episodes of percutaneous tibial nerve stimulation (PTNS) treatment for overactive bladder (OAB) symptoms in men and women and to determine the duration of the effects over a 6-month period.MethodsWomen and men with OAB symptoms participated in the study, which was conducted in accordance with an approved ethical protocol (ISRCTN15733799). Patients underwent six 30-min PTNS sessions, twice per week. The symptoms of OAB were assessed using a voiding diary, the short form of the Overactive Bladder Symptom Score questionnaire (OAB-q SF), and the Patient Perception of Bladder Condition (PPBC), which were self-completed by patients before and after treatment (24 h and at 1, 3, and 6 months). The outcome data were compared for sex and time points using two-way ANOVA for repeated measures.ResultsPTNS treatment significantly improved the OAB symptoms and quality of life in men and women. PTNS increased the voided volume (p &amp;lt; 0.05) and decreased the frequency of voiding, nocturia, and urgency at 24 h and up to 6 months (p &amp;lt; 0.001). The OABq-SF and PPBC scores were significantly decreased after PTNS (p &amp;lt; 0.001). Urgency was greater in men than in women. The duration of PTNS clinical success on frequency and the perception of improvement in quality of life were greater in women than in men.ConclusionThe clinical effects of six sessions of PTNS strongly suggest its potential for shortening, from the standard 12 sessions, to effectively alleviate symptoms of OAB. This therapeutic procedure would reduce both the time and economic costs of OAB treatment.

Clinical effect of phytosterol-enriched saw palmetto extract on urinary function in healthy middle-aged and older males: a double-blind, placebo-controlled randomized comparative study

Background: Saw palmetto extract (SPE) is one of the most widely used supplements for benign prostatic hyperplasia (BPH) due to its pharmacological effects. β-sitosterol-enriched saw palmetto oil (VISPO™) contains more than 3% β-sitosterol and 85% total fatty acids and has been shown to improve symptoms in patients with BPH. Lower urinary tract symptoms (LUTS) require primary preventive measures in countries with accelerated population aging, including Japan. VISPO™ is expected to be effective against the early symptoms of LUTS. However, the effect of VISPO™ on urinary function in healthy individuals has not been elucidated. Objective: This clinical study evaluated the efficacy and tolerability of VISPO™ in the management of urinary complaints among healthy middle-aged and older men who did not require treatment. Methods: We conducted a randomized, double-blind, placebo-controlled trial that included 54 male participants who were assigned to consume VISPO™ or placebo (olive oil) capsules for 12 weeks. Biometric data, uroflowmetry results, and salivary hormone levels were assessed at weeks 1 and 12. Urinary function and quality of life were assessed at weeks 1, 4, 8, and 12 using the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), Core Lower Urinary Tract Symptom Score (CLSS), and WHOQOL-26. Results: Two-way analysis of variance revealed that IPSS and OABSS were significantly lower in the VISPO™ group that in the placebo group. However, there were no significant differences in urine volume, urinary flow rate, or salivary hormone levels. In addition, no participants reported adverse effects (diarrhea, abdominal pain, etc.). Conclusion: The results of the present study, which is the first randomized controlled trial of VISPO™ conducted among healthy participants, demonstrate the effectiveness of VISPO™ in the management of lower urinary tract complaints that do not require treatment. Trial Registration: University Hospital Medical Information Network Clinical Trials Registry (UMIN000046386).

Favorable Postoperative Outcomes After Transvaginal Mesh Surgery Using a Wide-Arm ORIHIME® Mesh.

Introduction Transvaginal mesh surgery (TVM) is an effective treatment option for pelvic organ prolapse (POP). Although ORIHIME®, the only available mesh product, is thin, soft, and easy to handle, it has the disadvantages of sliding off or mildly adhering to the surrounding tissues. The current study compared the efficacy of using wide-arm ORIHIME (Kono Seisakusho, Japan, Tokyo), non-wide arm ORIHIME, GynemeshPS (Johnson and Johnson, Japan, Tokyo), and Polyform(Boston Scientific Japan, Japan, Tokyo) meshes for TVM. Methods The study included 116 patients who underwent TVM (Proliftwith GynemeshPS (n = 14); Elevatewith Polyform(n = 43); Upholdwith non-wide-arm ORIHIME(n = 24); Upholdwith wide-arm ORIHIME(n = 35)) at our hospital. Pre- and post-surgical changes in symptoms were measured using questionnaires and 60-minute pad weight testing and compared by mesh type and surgical methods used. Results The residual urine volume, 60-minute pad weight testing, international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), and international consultation on incontinence questionnaire-short form score (ICIQ-SF) significantly improved one year postoperatively in the TVM with the wide-arm ORIHIMEgroup. Comparison of preand one-year postoperative findings by mesh type and surgical methods used showed no significant differences in the 60-minute pad test, IPSS, Quality of Life (QOL), OABSS, and urinary incontinence in daily life scores, and improvement in residual urine volume, ICIQ-SF, and mesh exposure and POP recurrence rates in the TVM with the wide-arm ORIHIMEgroup. Conclusion TVM with wide-arm ORIHIMEhad better postoperative outcomes compared to TVM with other mesh products.

A Discrete Mathematics Approach for Understanding Risk Factors in Overactive Bladder Treatment.

Introduction Discrete mathematics, a branch of mathematics that includes graph theory, combinatorics, and logic, focuses on discrete mathematical structures. Its application in the medical field, particularly in analyzing patterns in patient data and optimizing treatment methods, is invaluable. This study, focusing on post-void residual (PVR) urine following overactive bladder (OAB) treatment, utilized discrete mathematics techniques to analyze PVR and its associated risk factors. Methods A retrospective study was conducted on 128 OAB patients who received intradetrusor onabotulinum toxin A injections between 2020 and 2022. Network graphs based on graph theory were used to analyze correlations between clinical variables, and clustering analysis was performed with PVR as the primary variable. Results The network graph analysis revealed that frailty, daytime frequency, and nocturia episodes were closely related to PVR. Clustering analysis with PVR as the primary variable divided the patients into three groups, suggesting that the group with particularly high frailty (Cluster 1) is at high risk for PVR. Moreover, significant differences in clinical indicators such as age, voiding efficiency, Overactive Bladder Symptom Score, and International Consultation on Incontinence Questionnaire-Short Form were observed in the remaining two clusters (Cluster 0 and 2). Conclusion This study demonstrates the effectiveness of discrete mathematics methods in identifying risk factors for PVR after OAB treatment and in distinguishing clinical subgroups based on patient characteristics. This approach could contribute to the formulation of individualized treatment strategies and the improvement of patient care quality. Further development and clinical application of this methodology are expected in future research.

THE RELATIONSHIP OF THE INCIDENT OF METABOLIC SYNDROME AND OVERACTIVE BLADDER IN FEMALE PATIENTS AT DR. M. DJAMIL PADANG IN 2023

Overactive Bladder (OAB) is a chronic medical condition that has a negative impact on an individual's health and quality of life. Cardiovascular problems are considered to be one of the risks associated with OAB where one of the higher cardiovascular parameters is metabolik syndrome. Aim to determine the relationship between  metabolik syndrome and Overactive Bladder in female patients at Dr. M. Djamil Hospital Padang. Quantitative research with a case control design using a questionnaire according to the Overactive Bladder Symptom Score (OABSS) and examination based on metabolik syndrome symptoms. The research was conducted at Dr. M. Djamil Hospital Padang in November 2022 to September 2023. There were 60 respondents who were divided into the OAB (28/60) and no-OAB group (32/60). Most respondents were aged 50-59 years (45,0%), graduated from high school (53.3%), worked as housewives (76.7%) and had diabetes mellitus (78,3%). In this study it was also found that 48,3% of respondents suffered from hypertension and 45.0% suffered from obesity. A total of 46.7% of respondents experienced OAB symptoms with a higher percentage of OAB found in the metabolik syndrome group (76,7%) than no-metabolik syndrome group (16.7%). Bivariate analysis found a relationship between metabolik syndrome and overactive bladder symptoms (p = 0.000) with metabolik syndrome affected the incidence of overactive bladder by 16.4 times (OR 16.42, (CI 95% 4.56-59.07). There is a relationship between metabolik syndrome and the incidence of OAB.

Association between oral frailty and lower urinary tract symptoms among middle-aged and older adults in community-dwelling individuals: a cross-sectional study.

We assessed the association between oral frailty risk and LUTS among middle-aged and older adults in a community-dwelling population. This cross-sectional study was conducted among 586 subjects aged ≥ 40years who participated in the Iwaki Health Promotion Project in Hirosaki, Japan. We used the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS) to assess LUTS. LUTS was defined as an IPSS score of 8 or higher or meeting diagnostic criteria for OAB. Oral frailty risk was defined as experiencing two or more of the following: decreased chewing ability, decreased biting force, and dry mouth sensation. Physical performance (10-m gait speed and grip strength) was used for analysis. The association between oral frailty risk and LUTS was examined using multivariate logistic regression analyses. The study included 218 men and 370 women, of whom 140 had LUTS. The mean age of this cohort was 59years. Significant differences were observed between the LUTS and non-LUTS groups, including age, hypertension, history of CVD, depressive status, sleep disturbance, and 10m gait speed. The prevalence of oral frailty risk was significantly higher in the LUTS group than in the non-LUTS group (26% vs. 11%, P < 0.001). Multivariate analysis revealed that age, male gender, and oral frailty risk (odds ratio: 2.67, 95% confidence interval: 1.57-4.51, P < 0.001) were independent factors for LUTS. Moreover, oral frailty risk was an independent factor in both participants aged < 65years and participants aged ≥ 65years. Oral frailty was independently associated with LUTS.
