ABSTRACT

PURPOSE: The objective was to evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) combined with mirabegron therapy compared with mirabegron monotherapy in the treatment of female patients with overactive bladder (OAB). METHODS: In this randomized controlled study, 100 female outpatients with OAB were screened. Among these patients, 86 who met the inclusion criteria were randomly divided into the TENS combined with mirabegron treatment group and mirabegron monotherapy treatment group, with 43 patients in each group. The voiding diary, Overactive Bladder Symptom Score (OABSS), Overactive Bladder Questionnaire Symptom Bother Score (OAB-q SBS), total health-related quality of life (OAB-q HRQoL), and treatment satisfaction-visual analog scale (TS-VAS) score before and after treatment were recorded to evaluate the efficacy of OAB treatment. Seventy-nine of the 86 patients (40 in the TENS plus mirabegron group and 39 in the mirabegron monotherapy group) completed 12 weeks of treatment. RESULTS: TENS combined with mirabegron therapy was superior to mirabegron monotherapy in improving the primary endpoints, including the daily number of micturition episodes and the daily MVV/micturition and secondary endpoints, including the daily number of urgency episodes, the OABSS, the OAB-q SBS, the HRQoL score and TS-VAS score. There were no statistically significant differences in urgency urinary incontinence and nocturia between the groups. Some minor adverse effects were observed, including muscle pain, local paresthesia and constipation. CONCLUSIONS: The combination of TENS and mirabegron was more effective than mirabegron alone in the treatment of female patients with OAB. TRIAL REGISTRATION NUMBER: ChiCTR2400080528 (31.01.2024, retrospectively registered).

ABSTRACT

PURPOSE: To compare the efficacy and safety of mirabegron and vibegron in female OAB patients. METHODS: We conducted a multicenter, prospective, randomized crossover study of female patients with OAB. The patients were assigned to Group MV (mirabegron for 8 weeks, followed by vibegron for 8 weeks) or group VM (vibegron for 8 weeks, followed by mirabegron for 8 weeks). The primary endpoint was the change in OABSS from baseline, and the secondary endpoint was the change in FVC parameters. After completion of the study, each patient was asked which drug was preferable. RESULTS: A total of 83 patients were enrolled (40 and 43 in groups MV and VM, respectively). At 8th and 16th week, 33 and 29 in Group MV and 34 and 27 in Group VM continued to receive the treatment. The change in PVR was not significantly different between treatment with mirabegron and vibegron. The changes in OABSS, nighttime frequency, mean, and maximum voided volume were similar between mirabegron and vibegron. The mean change in the daytime frequency was greater in the vibegron than in the mirabegron. Of the 56 patients, 15 (27%) and 30 (53%) preferred mirabegron and vibegron, respectively. The remaining 11 patients (20%) showed no preference. The change in the urgency incontinence score during vibegron was better in patients who preferred vibegron to mirabegron. CONCLUSION: The efficacies of mirabegron and vibegron in female patients was similar. The patients' preference for vibegron could depend on the efficacy of vibegron for urgency incontinence.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Medical treatments for overactive bladder (OAB) have proven efficacy in controlled trials. However, 1-year treatment persistence is reported to be as low as 25% for anticholinergics and 40% for ß3 agonists. Real-world data on treatment continuation and treatment sequence is limited. Therefore, we aimed to study treatment persistence trends in women initiated on OAB medications. MATERIALS AND METHODS: We used advanced data-mining techniques to query the largest regional provider's medication purchase database, dispensing for patients, for all women initiating OAB pharmacotherapy between 2010 and 2020. Treatment persistence was measured as days in which the patient was in possession of medication and nonpersistence was defined as prescription nonrefilling for 90 days. We employed a Sankey diagram to explore trends in OAB medication acquisition and treatment sequence. We compared treatment persistence using Kaplan-Meier survival curves and pairwise log-rank analysis. RESULTS: Here, 46 079 women made 791 681 unique claims of OAB medications. Only 39% of the patients tried more than one OAB formulation, including dose change. The overall persistence rate for all drugs was 55% in 30 days, 46% in 90 days, and 37% per year. The persistence rate for Mirabegron at 30 days was 54%, 42% at 90 days, and 17% at 1 year. Overall, persistence rates were unchanged when stratifying by the time Mirabegron insurance acceptance into coverage (p > 0.05). CONCLUSIONS: Real-world OAB pharmacotherapy persistence rates are lower than previously reported. The introduction of Mirabegron did not seem to improve these rates or affect the treatment sequence.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: We aimed to determine whether the presence of metabolic syndrome (MS) affects the efficacy of mirabegron in treatment-naïve women with overactive bladder (OAB). METHODS: Women being treated with mirabegron 50 mg were allocated to MS and non-MS groups, and the efficacy of treatment of OAB was compared using the OAB symptom score (OABSS) and a 3-day voiding diary before and 12 weeks after starting treatment. The Wilcoxon signed-rank and Mann-Whitney U tests and multivariate logistic regression were used for statistical analyses, and a p-value < 0.05 was considered to represent statistical significance. RESULTS: Of the 197 patients who completed the trial, 43 (23.9%) had MS. After 12 weeks of mirabegron treatment, both the MS and non-MS groups showed significant improvements in OABSS score, the number of incontinence episodes/24 h, the number of micturition episodes/24 h, and the number of episodes of urgency/24 h. The factors associated with clinically important differences in OABSS were the presence of hyperglycemia (odds ratio 2.43, 95% confidence interval [CI] 1.05-5.60) and OABSS score at baseline (odds ratio 1.23, 95% CI 1.09-1.39). CONCLUSIONS: Mirabegron is effective in patients with and without MS, and comorbid hyperglycemia and severe OAB symptoms before treatment are predictors of the efficacy of mirabegron treatment.

ABSTRACT

PURPOSE: Medical expulsive therapy (MET) is recommended for distal ureteral stones from 5 to 10 mm. The best drug for MET is still uncertain. In this review, we aim to compare the effectiveness of tadalafil and tamsulosin for distal ureteral stones from 5 to 10 mm in terms of stone expulsion rate (SER), stone expulsion time (SET) and the side effect profile. MATERIALS AND METHODS: A comprehensive literature search was conducted on MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science, from inception until April 2023. Only randomized controlled trials were included in the analysis. RESULTS: Eleven publications with 1,330 patients were included. We observed that tadalafil has a higher SER (OR 0.55, CI 95% 0.38;0.80, p=0.02, I2=52%) and the same efficacy in SET (MD 1.07, CI 95% -0.25; 2.39, p=0.11, I2=84%). No differences were found when comparing side effects as headache, backache, dizziness, and orthostatic hypotension. CONCLUSION: Tadalafil has a higher stone expulsion rate than tamsulosin as a medical expulsive therapy for patients with distal stones from 5 to 10 mm without differences in side effects.

ABSTRACT

PURPOSE: To assess the prescribing practices for overactive bladder (OAB) pharmacotherapy based on the prescription trend analysis across different specialties of India. METHOD: s: IQVIA (Quintiles and IMS Health) secondary sales audit (SSA), as well as a prescription audit for antimuscarinics and beta-3 adrenoceptor agonists (mirabegron) from 2014 to 2021, were analyzed. The data includes SSA data of various antimuscarinics like solifenacin, oxybutynin, tolterodine, darifenacin, trospium and mirabegron change in the prescription trend of antimuscarinics and mirabegron across different specialties; prescribers overlap analysis for solifenacin and mirabegron among Indian urologists were also analyzed. RESULTS: Urologists prescription rates of OAB drugs were 65% in 2016 and 54% in 2021. The rate of OAB medication prescription by non-urologist was highest from the surgeon (11%), followed by gynecologists (9%) and consultant physicians (8%) in 2021. In addition, among OAB medication prescription rates for antimuscarinics were 100% in 2016 and 58% in 2021 whereas for mirabegron, it was 0% in 2016 and 42% in 2021. Solifenacin was most frequently prescribed anticholinergics, followed by oxybutynin, tolterodine, darifenacin, and trospium. The proportion of prescribers of OAB medication among urologists was 38% in 2016 and 33% in 2021. Exclusive prescribers of solifenacin were 748 in 2018 and 739 in 2021 at the urologist, whereas for mirabegron, it was 961 in 2018 and 934 in 2021. The compound annual growth rate for prescription of the last 6 years (from 2016-2021) for solifenacin and mirabegron was -3% and 8% respectively. CONCLUSIONS: Urology remained a top prescribing specialty for OAB drugs, although prescription share increased at surgeon and consultant physician. OAB medicines prescriptions by urologists are shifting from leading antimuscarinic solifenacin to beta-agonist mirabegron. Data from this study will ultimately lead to the OAB medication preference by the specialist that could lead to more advanced OAB management.

ABSTRACT

PURPOSE: We aimed to assess the efficacy and safety of Mirabegron vs. solifenacin to treat LUTS resulting from DJ-stent insertion. METHODS: A total of 97 patients who had DJ-stent inserted for urinary stone disease were randomly divided into three groups according to received treatment. Group A took Mirabegron 50 mg daily, group B took solifenacin 5 mg daily from the 4th day after stent placement until the stent was removed, and group C only was hydrated well. All patients were evaluated by USSQ and IPSS at 4th day post-insertion of ureteral stent, follow-up day before removing of stent and post-removal of stent. RESULTS: The USSQ urinary symptom scores at day 4 comparing to day of removal of stent showed significant difference in between study groups (32 ± 6-13 ± 6 vs. 31 ± 6-14 ± 4 in Mirabegron and solifenacin, respectively) and without significant difference in control group. The USSQ body pain score significantly decreased in both Mirabegron and solifenacin groups at day of stent removal comparing to day 4 post-insertion of DJ with insignificant decreasing in the control group. Quality of life scores showed significant improving in Mirabegron and solifenacin group, and there was no difference in control group at 4 and 14 days after treatment. No severe complications were observed in either group. DISCUSSION/CONCLUSION: In our series, we indicate that Mirabegron and solifenacin can be used to improve symptoms caused by the insertion of DJ-stent without significant difference.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Mirabegron, a beta-3 agonist, is prescribed for urgency urinary incontinence (UUI). We assessed the correlation of symptom improvement with urobiome characteristics in adult women participants prescribed mirabegron for UUI treatment. METHODS: We enrolled participants seeking UUI treatment who selected mirabegron and agreed to participate in this 12-week, open label study conducted at the Female Pelvic Medicine and Reconstructive Surgery Center at Loyola University Medical Center. Following eligibility screening and research consent, participants completed the overactive bladder questionnaire (OAB-Q) and provided a catheterized urine sample at baseline, 4, 8, and 12 weeks. The primary outcome, symptom improvement at 12 weeks, was based on the validated Patient Global Symptom Control questionnaire score to dichotomize symptom response (responder vs nonresponder [PGSC score ≤3]). Urine samples were processed by the Expanded Quantitative Urine Culture (EQUC) protocol. RESULTS: Eighty-three participants (mean age 68 years) completed baseline assessment. Of the 47 participants with primary outcome data and samples analysis, there were 16 responders and 31 nonresponders; responder groups were similar demographically. Living microbes were detected in most participants. There were no significant differences in alpha diversity (within sample) at baseline between groups. However, at the 12-week follow-up, the responder urobiome became significantly richer, with a larger number of genera (p = 0.027) and was significantly more diverse than the nonresponders. CONCLUSIONS: Longitudinal urobiome changes are associated with symptom improvement in adult women being treated with mirabegron for UUI. The mechanism for symptoms improvement may relate to the detected changes in the urobiome and warrants further study.

ABSTRACT

BACKGROUND: Immunoglobulin G4-related disease (IgG4-RD) is a systemic lymphoproliferative disorder characterized by elevated serum IgG4 levels and tumefactive lesions that can involve nearly every organ system. Involvement of the prostate is rare but has been reported in limited cases. CASE PRESENTATION: A 28-year-old man of Asian descent with a history of sinusitis and priapism presented to hospital with rigors and voiding symptoms. He was diagnosed with IgG4-RD one month prior to presentation, following pathological analysis of a submandibular mass that demonstrated chronic sclerosing sialadenitis. On presentation, white blood cell count, C-reactive protein, and prostate serum antigen levels were all within normal limits. Examination was notable for a large, firm prostate, and a foley catheter was inserted. Contrast CT of the abdomen was unremarkable. Further workup revealed elevated serum IgG4 levels (9.22 g/L) and he was subsequently started on prednisone 35 mg daily. Imaging to screen for systemic IgG4-RD involvement demonstrated paravertebral soft tissue involvement and he was given rituximab 1000 mg IV × 2 doses. MRI revealed diffuse prostatitis. Five days after starting prednisone and one day after his first dose of rituximab, he successfully passed trial of void and was discharged home. CONCLUSIONS: IgG4-related prostatitis is a rare and underrecognized manifestation of IgG4-RD. Our case highlights the need to consider IgG4-related prostatitis as an etiology of urinary obstruction in young individuals. Resolution of symptoms following treatment with steroids may be diagnostic of IgG4-related prostatitis, and may potentially avoid the need for invasive diagnostic procedures such as prostate biopsy.

ABSTRACT

BACKGROUND: We assessed the efficacy and safety of mirabegron, a ß3-adrenoceptor agonist, in older adults (≥ 80 years old) with overactive bladder (OAB). METHODS: OAB patients aged ≥ 80 years were enrolled in this prospective, single-arm observational study. OAB was diagnosed based on the OAB symptom score (OABSS); i.e., a total score of ≥ 3 points and an urgency score of ≥ 2 points. Patients who received 50 mg mirabegron once daily were evaluated at the baseline and at 4, 8, and 12 weeks. The changes from the baseline in the OABSS, International Prostate Symptom Score (IPSS), OAB questionnaire (OAB-q) score, and Vulnerable Elders Survey (VES-13) score were determined. Adverse events, laboratory tests, 12-lead electrocardiography, the QT interval according to Fridericia's formula (QTcF), uroflowmetry, the post-void residual urine volume (PVR), and the Mini-Mental State Examination (MMSE) score were used to assess safety. RESULTS: Forty-three patients (median age: 84 years, range: 80-96 years) were examined. They had high rates of comorbidities and polypharmacy. Mirabegron significantly improved in total score of the OABSS, including urgency and urge incontinence. The total IPSS, IPSS quality-of-life (QOL) index, and OAB-q scores also significantly improved. Mirabegron improved in the VES-13 score. There were no significant changes in laboratory test values, uroflowmetry findings, PVR, the QTcF, or MMSE score. Two patients (4.7%) withdrew from the study after experiencing adverse events. CONCLUSIONS: Mirabegron was well tolerated and significantly improved in OAB symptoms, and QOL in older patients. Trial registration The present clinical study was approved by University of Yamanashi Institutional Review Board prior to study initiation (ID1447) and was retrospectively registered with the UMIN Clinical Trials Registry (UMIN-CTR), Japan (UMIN000045996) on Nov 6, 2021.

ABSTRACT

BACKGROUND: Several studies described post-operative irritative symptoms after laser enucleation of prostate, sometimes associated with urge incontinence, probably linked to laser-induced prostatic capsule irritation, and potential for lower urinary tract infections We aimed to evaluate the efficacy of a suppository based on Phenolmicin P3 and Bosexil (Mictalase®) in control of irritative symptoms in patients undergoing thulium laser enucleation of prostate (ThuLEP). METHODS: In this single-center, prospective, randomized, open label, phase-III study, patients with indication to ThuLEP were enrolled (Dec2019-Feb2021-Institutional ethics committee STS CE Lazio approval no.1/N-726-ClinicalTrials.gov NCT05130918). The report conformed to CONSORT 2010 guidelines. Eligible patients were 1:1 randomized. Randomization defined Group A: patients who were administered Mictalase® suppositories twice a day for 5 days, then once a day for other 10 days; Group B: patients who did not receive Mictalase® ("controls"). Study endpoints were evaluated at 15 and 30 days postoperation. Primary endpoint included evaluation of effects of the suppository on irritative symptoms by administering IPSS + QoL questionnaire. Secondary endpoint included evaluation of effects on urinary tract infections by performance of urinalysis with urine culture. RESULTS: 111 patients were randomized: 56 in Group A received Mictalase®. Baseline and perioperative data were comparable. At 15-days, no significant differences were found in terms of IPSS + QoL scores and urinalysis parameters. A significant difference in the rate of positive urine cultures favored Group A (p = 0.04). At 30-days follow-up, significant differences were found in median IPSS score (6 [IQR 3-11] versus 10 [5-13], Group A vs B, respectively, p = 0.02). Urinalysis parameters and rate of positive urine cultures were not significantly different. CONCLUSIONS: The present randomized trial investigated the efficacy of Mictalase® in control of irritative symptoms and prevention of lower urinary tract infections in patients undergoing ThuLEP. IPSS improvement 30-days postoperation was more pronounced in patients who received Mictalase®. Lower rate of positive urine culture favored Mictalase® group 15-days postoperatively. TRIAL REGISTRATION: The clinical trial has been registered on ClinicalTrials.gov on November 23rd, 2021-Registration number NCT05130918.

ABSTRACT

The selective ß 3-adrenoceptor agonist mirabegron, an established alternative to antimuscarinic therapy for patients with overactive bladder, induces additional effects against receptors, transporters, and hepatic enzymes. The present study aimed to elucidate the effects of mirabegron on muscarinic receptors in the rat bladder using radioligand binding and functional assays. Mirabegron (0.1-100 µM) inhibited specific [N-methyl-3H]scopolamine methyl chloride binding in the bladder and other tissues of rats in a concentration-dependent manner. Binding affinity in the bladder was similar to that in the heart and significantly higher than those in the submaxillary gland and brain. Mirabegron induced the concentration-dependent relaxation of carbachol-induced contractions in the rat isolated bladder. Further analyses using a two-site model revealed that the relative quantities of high- and low-affinity components for mirabegron were 44.5% and 55.5%, respectively. Respective pEC50 values were 7.06 and 4.97. Based on the receptor binding affinity and pharmacokinetics of mirabegron, muscarinic receptor occupancy in the human bladder for 24 hours after the administration of a single oral dose of 50 mg mirabegron was 37%-76%. The present results demonstrate for the first time that mirabegron may relax the detrusor smooth muscle not only by ß 3-adrenoceptor activation but also muscarinic receptor blockade. SIGNIFICANCE STATEMENT: Mirabegron, the first selective ß 3-adrenoceptor agonist, represents an alternative to antimuscarinic agents for management of overactive bladder (OAB). The present study aimed to clarify whether mirabegron directly binds to muscarinic receptors and affects cholinergic agonist-induced contractions in rat urinary bladder and to predict muscarinic receptor occupancy in human bladder after oral administration of mirabegron. The results demonstrated that mirabegron therapy for patients with OAB may be due not only to ß 3-adrenoceptor activation but also muscarinic receptor blockade.

ABSTRACT

PURPOSE: Ureteral injury is a frequent complication of ureteral access sheath deployment. We sought to define the safe threshold of force for the passage of a ureteral access sheath using a novel ureteral access sheath force sensor. MATERIALS AND METHODS: Ureteral access sheath-force sensor measurements were recorded in 210 renal units. A 16Fr ureteral access sheath was deployed initially based on a prior porcine study. If 6 N was reached, the surgeon was advised to downsize the 16Fr ureteral access sheath. In each case, a post-ureteroscopic lesion scale was recorded. Regression models were used to estimate the impact of adjusted variables on post-ureteroscopic lesion scale grade, 16Fr ureteral access sheath deployment, and peak force. RESULTS: A 16Fr ureteral access sheath was deployed in 127 (61%) renal units with a mean peak force of 5.7 N. Two high-grade ureteral injuries occurred; in both cases >6 N of force was recorded. Post-ureteroscopic lesion scale grade correlated directly with peak insertion force (p <0.01). Bacteriuria within 60 days of the procedure (OR 2.009, p=0.034), combination of preoperative stent plus oral tamsulosin (OR 2.998, p=0.045), and prior ipsilateral stone surgery (OR 2.13, p=0.01) were independent predictors of successful 16Fr ureteral access sheath deployment. Among patients with neither prior ipsilateral stone surgery nor preoperative stent, preoperative tamsulosin facilitated passage of a 16Fr ureteral access sheath (OR 2.750, p=0.034). CONCLUSIONS: Ureteral access sheath associated ureteral injury can be averted by limiting the insertion force to ≤6 N. Prior stone surgery, preoperative indwelling ureteral stent plus oral tamsulosin, and recently treated bacteriuria favored passage of a 16Fr ureteral access sheath. In the naïve, unstented patient, preoperative tamsulosin favored deployment of a 16Fr ureteral access sheath.

ABSTRACT

PURPOSE: Williams-Beuren syndrome is a chromosomal disorder caused by a deletion at region 7q11.23. Lower urinary tract symptoms are highly prevalent and significantly affect quality of life. We assessed the long-term outcomes of lower urinary tract symptoms in children with Williams-Beuren syndrome. MATERIALS AND METHODS: From February 2001 to July 2016, 90 patients with Williams-Beuren syndrome were evaluated in our hospital, of whom 31 (20 boys) had at least 5 years of followup. Baseline evaluation included a history of lower urinary tract symptoms, frequency-volume chart and the impact on quality of life measured on a scale of 0 (delighted) to 6 (terrible). Pharmacological therapy with oxybutynin or doxazosin was offered to symptomatic patients. We present the outcome of lower urinary tract symptoms after 5 and 10 years of followup. RESULTS: At baseline 27 (87.1%) patients were symptomatic. Median duration of followup was 10 (range 6-13) years. Pharmacological therapy was started for 25 (92.6%) symptomatic patients at baseline, including oxybutynin for 19 (76.0%), doxazosin for 1 (4.0%) and a combination of the 2 agents for 5 (20.0%). Medical therapy was still in use by 61.2% after 5 years and 52.9% after 10 years (p=0.043). Median duration of pharmacological treatment was 7 (range 6-11) years. A significant improvement of lower urinary tract symptoms was observed over time, with 35.5% and 29.5% patients considered symptomatic after 5 years and 10 years, respectively (p <0.001). Quality of life was also markedly improved over time (p <0.001). CONCLUSIONS: This long-term study showed significant improvement of lower urinary tract symptoms in children and adolescents with Williams-Beuren syndrome over time. Long-term pharmacological treatment was needed in most patients.

ABSTRACT

PURPOSE: Benign prostatic hyperplasia (BPH) is a histologic diagnosis describing proliferation of smooth muscle and epithelial cells within the prostatic transition zone. The prevalence and severity of lower urinary tract symptoms (LUTS) in aging men are progressive and impact the health and welfare of society. This revised Guideline provides a useful reference on effective evidence-based management of male LUTS/BPH. See the accompanying algorithm for a summary of the procedures detailed in the Guideline (figures 1 and 2[Figure: see text][Figure: see text]). MATERIALS AND METHODS: The Minnesota Evidence Review Team searched Ovid MEDLINE, Embase, Cochrane Library, and AHRQ databases to identify eligible English language studies published between January 2008 and April 2019, then updated through December 2020. Search terms included Medical Subject Headings (MeSH) and keywords for pharmacological therapies, drug classes, and terms related to LUTS or BPH. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, information is provided as Clinical Principles and Expert Opinions (table 1[Table: see text]). RESULTS: Nineteen guideline statements pertinent to evaluation, work-up, and medical management were developed. Appropriate levels of evidence and supporting text were created to direct both primary care and urologic providers towards streamlined and suitable practices. CONCLUSIONS: The work up and medical management of BPH requires attention to individual patient characteristics, while also respecting common principles. Clinicians should adhere to recommendations and familiarize themselves with standards of BPH management.

ABSTRACT

BACKGROUND: Postoperative urinary retention is common after female pelvic reconstructive surgery. Alpha receptor antagonists can improve dysfunctional voiding by relaxing the bladder outlet and may be effective in reducing the risk of postoperative urinary retention. OBJECTIVE: This study aimed to determine whether tamsulosin is effective in preventing postoperative urinary retention in women undergoing surgery for pelvic organ prolapse. STUDY DESIGN: This was a multicenter, double-blind, randomized controlled trial between August 2018 and June 2020, including women undergoing surgery for pelvic organ prolapse. Patients were excluded from recruitment if they had elevated preoperative postvoid residual volume, history of postoperative urinary retention, or a contraindication to tamsulosin. Those who experienced cystotomy were excluded from analysis. Participants were randomized to a 10-day perioperative course of tamsulosin 0.4 mg vs placebo, beginning 3 days before surgery. A standardized voiding trial was performed on postoperative day 1. The primary outcome was the development of postoperative urinary retention, as defined by the failure of the voiding trial or subsequent need for catheterization to empty the bladder. Secondary outcomes included the rate of urinary tract infection and the impact on lower urinary tract symptoms as measured by the American Urological Association Symptom Index. RESULTS: Of 119 patients, 57 received tamsulosin and 62 received placebo. Groups were similar in regard to demographics, preoperative prolapse and voiding characteristics, and surgical details. Tamsulosin was associated with a lower rate of postoperative urinary retention than placebo (5 patients [8.8%] vs 16 patients [25.8%]; odds ratio, 0.28; 95% confidence interval, 0.09-81; P=.02). The number needed to treat to prevent 1 case of postoperative urinary retention was 5.9 patients. The rate of urinary tract infection did not differ between groups. American Urological Association Symptom Index scores significantly improved after surgery in both groups (median total score, 14 vs 7; P<.01). Scores related to urinary stream improved more in the tamsulosin group than in placebo (P=.03). CONCLUSION: In this placebo-controlled trial, tamsulosin use was associated with a reduced risk of postoperative urinary retention in women undergoing surgery for pelvic organ prolapse.

ABSTRACT

AIMS: To descriptively evaluate treatment persistence among adults who received mirabegron or antimuscarinics in South Korea. METHODS: This study involved a retrospective analysis of the Health Insurance Review and Assessment (HIRA) database. Patients (≥18 years) who had a new prescription for an overactive bladder (OAB) target medication (mirabegron/antimuscarinic) within an 8-month index period (July 1, 2015-February 29, 2016) were included. The date when the target (index) medication was dispensed was the index date. The 6-month period before the index date was used to assess patient eligibility. A 12-month post-index period was used to assess medication persistence, which was defined as the time to discontinuation. Overall data were analyzed and the results were also stratified by age group (≤65, >65 years), sex, or prior OAB medication experience. Persistence rates were calculated after the 1st, 3rd, 6th, 9th, and 12th months. RESULTS: A data set of 52 722 cases was obtained (mirabegron: 11 424, antimuscarinics: 41 298). The mean age was 60.9 ± 16.1 years and the majority of the patients were female (30 862 [58.5%] patients). Median persistence was longer with mirabegron (51 days) versus antimuscarinics (25 days). The persistence rate with mirabegron was higher throughout the study compared with all the antimuscarinics (12-month data: 13.5% and 4.9%, respectively). Longer treatment persistence was noted in older, male, and treatment-experienced patients. CONCLUSION: The results from the HIRA database showed that persistence was longer with mirabegron than with antimuscarinics in South Korea. This finding may help inform clinical decision-making within the South Korean healthcare system.

ABSTRACT

AIMS: This study aimed to investigate the efficacy and safety of mirabegron for Parkinsonism patients with overactive bladder (OAB) symptoms in a randomized, placebo-controlled, multicenter study. MATERIALS AND METHODS: Inclusion criteria are Parkinsonism with OAB symptoms for 4 weeks or more, OAB symptom score (OABSS) questionnaire scores greater than 2, and OABSS urgency question scores greater than 1. After a 2-week wash-out period, the patients were randomized into placebo and mirabegron groups at visit 2. Visit 3 was performed after 4 weeks of medication. Mirabegron was prescribed to the two groups for the rest of the study period at visit 4. RESULT: The mean age was 68.1 ± 8.1 years and 72 males and 64 females were included. A total of 136 patients were screened, 117 patients were randomized, and 25 patients dropped out. The OABSS scores were significantly different between the two groups at Weeks 4 and 8. The OABSS scores became the same in the two groups at Week 12 (visit 5). The postvoid residual urine volume showed a mild increase to 64 ml in the mirabegron group compared to the placebo group at visit 4. Adverse events occurred in 27 patients (23.1%). The degree was mild in 26 cases (78.8%), moderate in five (15.2%), and severe in two (6.1%). Only 13 cases (39.4%) showed medication-related adverse events. Acute urinary retention occurred in a single case. The treatment satisfaction questionnaires showed no significant differences between the two groups. CONCLUSION: Mirabegron was effective in treating OAB symptoms in patients with Parkinsonism with acceptable adverse events.

ABSTRACT

PURPOSE OF REVIEW: To review the efficacy and safety of mirabegron in men with overactive bladder (OAB) and benign prostatic hyperplasia (BPH). RECENT FINDINGS: Numerous studies have shown mirabegron to be efficacious and safe in treating symptoms of OAB. More recent studies evaluating the use of mirabegron in men with OAB and BPH have also shown the medication to be effective with few adverse side effects when used as monotherapy or in combination therapy. Mirabegron is an effective and safe treatment for men with OAB and BPH.

ABSTRACT

BACKGROUND: Benign prostatic hyperplasia (BPH) is very common in aging men. We aimed to compare the effects of tamsulosin and pumpkin (Cucurbita pepo) seed oil on BPH symptoms. METHODS: This single-blind randomized clinical trial included patients with BPH aged ≥ 50 years referred to the Urology Clinic of Shahid Beheshti Hospital, Hamadan, Iran, from August 23, 2019 to February 19, 2020. Patients were randomized into two groups. One group received 0.4 mg tamsulosin every night at bedtime and the other received 360 mg pumpkin seed oil twice a day. Patients' age, weight, height, and body mass index (BMI) were recorded. The International Prostate Symptom Score (IPSS) was filled out by the patients at baseline and then 1 month and 3 months after the initiation of treatment. The BPH-associated quality of life (QoL), serum prostate-specific antigen, prostate and postvoid residual volume, and maximum urine flow were also assessed at baseline and 3 months later. Drug side effects were also noted. RESULTS: Of the 73 patients included in this study with a mean age of 63.59 ± 7.04 years, 34 were in the tamsulosin group and 39 in the pupkin seed oil group. Patients were comparable with respect to age, weight, height, BMI, and baseline principal variables in both groups. Also, there was no significant difference between groups in terms of principal variables at any time point. However, there was a significant decrease in IPSS and a significant improvement in QoL in both groups. Although the decrease in IPSS from baseline to 1 month and 3 months was significantly higher in the tamsulosin group compared to the pumpkin group (P = 0.048 and P = 0.020, respectively), the decrease in IPSS from 1 to 3 months was similar (P = 0.728). None of the patients in the pumpkin group experienced drug side effects, while dizziness (5.9%), headache (2.9%), retrograde ejaculation (2.9%), and erythema with pruritus occurred in the tamsulosin group. CONCLUSIONS: Pumpkin (Cucurbita pepo) seed oil relieved BPH symptoms with no side effects, but was not as effective as tamsulosin. Further studies are required to confirm the role of pumpkin seed oil as an option for the treatment of BPH symptoms. Trial registration Iranian Registry of Clinical Trials, IRCT20120215009014N340.
