[Digital health applications in urology]. / Digitale Gesundheitsanwendungen in der Urologie.

BACKGROUND: Digital health applications (DiGA) were included in the German healthcare system in 2020. They are available for prescription and reimbursed by public and private insurance companies. For the specialty of urology, there are currently two DiGA available: for the treatment of erectile dysfunction and benign prostatic hyperplasia/overactive bladder (BPH/OAB). The legal basis, clinical results and practical implementation are presented. METHODS: Evaluation of websites and publications to show the regulatory requirements, mode of action, results of clinical trials and prescribing practice with DiGA. RESULTS: Since 2020, 63 DiGA have been listed in the register of the Federal Office for Drugs and Medical Devices (BfArM), 35 of them definitively. Two urological DiGA aim to treat erectile dysfunction and BPH/OAB. Randomized, controlled studies have shown a significant and clinically relevant patient benefit for both DiGA. Further urological DiGA are in clinical development. CONCLUSIONS: DiGAs offer multimodal therapy combinations that have not yet been used in clinical practice and show a multidimensional benefit for the patient.

[Magnetic stimulation combined with moxibustion improves mild to moderate overactive bladder and sexual function in women].

OBJECTIVE: To investigate the clinical effect of magnetic stimulation combined with moxibustion on mild to moderate overactive bladder (OAB) and sexual function in women. METHODS: We enrolled 80 female patients with mild to moderate OAB in this study and equally randomized them into a control and an experimental group, the former treated by magnetic stimulation and the latter by magnetic stimulation combined with moxibustion, both for 8 weeks. We obtained from the patients their OAB syndrome scores (OABSS), 72-hour urination diary (72-h UD) scores, International Consultation on Incontinence Questionnaire － Overactive Bladder (ICIQ-OAB) scores and female sexual function indexes (FSFI), and compared them between the two groups before and after intervention. RESULTS: A total of 77 patients completed the study, 37 in the control and 40 in the experimental group. There were no statistically significant differences in the baseline data between the two groups (P > 0.05). Compared with the baseline, the experimental group showed significant improvement after treatment in the OABSS (7.54±1.12 vs 4.46±0.96), 72-h urine volume (ï¼»126.40±46.04ï¼½ vs ï¼»216.63±38.26ï¼½ ml), urination frequency (15.55±3.21 vs 8.03±1.40), ICIQ-OAB score (10.25±1.15 vs 6.32±1.07) and FSFI (20.00±12.40 vs 33.30±21.00) (all P < 0.05), even more significantly than in the control group (OABSS: 4.46±0.96 vs 5.59±0.90; 72-h urine volume: ï¼»216.63±38.26ï¼½ vs ï¼»173.41±15.55ï¼½ ml; urination frequency: 8.03±1.40 vs 9.90±1.49; ICIQ-OAB score: 6.32±1.07 vs 7.89±0.77; FSFI: 33.30±21.00 vs 30.40±10.40) (all P < 0.01). CONCLUSION: Magnetic stimulation combined with moxibustion can improve the symptoms of mild to moderate overactive bladder and improve sexual function in females.

Lactobacillus-Polydopamine System for Targeted Drug Delivery in Overactive Bladder: Evidence from Bladder Cell Spheroids, Rat Models, and Urinary Microbiome Profiling.

Introduction: Overactive bladder (OAB) is a highly prevalent condition with limited treatment options due to poor efficacy, side effects, and patient compliance. Novel drug delivery systems that can target the bladder wall may improve OAB therapy. Methods: We explored a polydopamine (PDA)-coated lactobacillus platform as a potential carrier for localized OAB treatment. Urinary microbiome profiling was performed to identify the presence of lactobacillus in healthy and OAB groups. Lactobacillus-PDA nanoparticles were synthesized and characterized by electron microscopy and spectrophotometry. A rat bladder perfusion model and human bladder smooth muscle cell spheroids were used to assess the distribution and penetration of the nanoparticles. The efficacy of the Lactobacillus-PDA system (LPS) for delivering the antimuscarinic drug solifenacin was evaluated in an OAB rat model. Results: Urinary microbiome profiling revealed lactobacillus as a dominant genus in both healthy and OAB groups. The synthesized Lactobacillus-PDA nanoparticles exhibited uniform size and optical properties. In the rat bladder perfusion model, the nanoparticles distributed throughout the bladder wall and smooth muscle without toxicity. The nanoparticles also penetrated human bladder smooth muscle cell spheroids. In the OAB rat model, LPS facilitated the delivery of solifenacin and improved treatment efficacy. Discussion: The results highlight LPS as a promising drug carrier for targeted OAB therapy via penetration into bladder tissues. This bacteriotherapy approach may overcome limitations of current systemic OAB medications. Lactobacillus, a probiotic bacterium present in the urinary tract microbiome, was hypothesized to adhere to and penetrate the bladder wall when coated with PDA nanoparticles, making it a suitable candidate for localized drug delivery.

Management of overactive bladder: consensus statements from the Hong Kong Urological Association and the Hong Kong Geriatrics Society.

Overactive bladder (OAB) is a common urological disease with a high prevalence in older adult populations. Antimuscarinic drugs have been the most common treatment for OAB for more than a decade, but their anticholinergic side-effects and potential impact on cognitive function among older patients are usually underestimated. This consensus aimed to provide practical recommendations concerning OAB management, with a particular emphasis on older patients. A joint consensus panel was formed by representatives of the Hong Kong Urological Association and the Hong Kong Geriatrics Society. Literature searches regarding OAB and its management were performed in PubMed and Ovid. Several working meetings were held to present and discuss available evidence, develop consensus statements, and vote for the statements. A modified Delphi method was used in this consensus process. To address questions regarding various aspects of OAB, 29 consensus statements were proposed covering the following areas: diagnosis, initial assessment, non-pharmacological treatments, considerations before administration of pharmacological treatments, various pharmacological treatments, combination therapy, and surgical treatment. Twenty-five consensus statements were accepted.

Evaluating repetitive transcranial magnetic stimulation for neurogenic overactive bladder management in stroke survivors: A randomized sham-controlled trial protocol.

BACKGROUND: Neurogenic overactive bladder (OAB) is a distressing condition in stroke. Existing neurogenic OAB management is expensive, unstandardized regimens, or invasive. Evaluating the effectiveness of repetitive transcranial magnetic stimulation (rTMS) remains crucial. We aimed to (1) compare the effectiveness of active-rTMS with sham-rTMS on neurogenic OAB symptoms, (2) analyze whether rTMS is cost-effective, and (3) explore the rTMS's experiences on participants' symptoms. METHODS: This is a randomized, sham-controlled, double-blinded trial with embedded qualitative and cost-effectiveness studies. A total of 110 stroke survivors with neurogenic OAB symptoms were screened for eligibility; 60 participants were eligible for inclusion and were randomly assigned to either the active (n = 30) or sham-rTMS (n = 30) groups using a computer-generated randomization schedule. The active-rTMS group received low-frequency rTMS of 1200 pulses per session lasting 20 min thrice weekly to pelvic floor muscle representation at the contralesional primary motor cortex. The sham-rTMS group received low-frequency stimulation at a 20 % resting motor threshold using the same coil as the active-rTMS but was configured to reduce the TMS-induced electrical fields significantly. The primary and secondary outcome measures were assessed at baseline, post-intervention (week 4) and follow-up (week 8). The analysis of covariance (ANCOVA) analysis compared changes in the study groups. Quality-adjusted life-years (QALY) were measured to evaluate the cost-effectiveness while EQ-5D-5L estimated QALY changes. Additionally, the focus group discussion data were thematically analyzed. CONCLUSIONS: The findings from this rTMS intervention study will be useful in alleviating neurogenic OAB symptoms and enhancing patient satisfaction in a cost-effective way.

Urotherapy and biofeedback resistant dysfunctional voiding: How to deal with?

OBJECTIVES: To analyze the management strategies in the children who had treatment-resistant dysfunctional voiding (DV). METHODS: Among 75 children with DV who underwent pelvic floor biofeedback therapy (BF) between 2013 and 2020, 16 patients (14 girls, 87.5%) with a mean age of 9.81 ± 2.53 years that showed incomplete clinical response following urotherapy and initial BF sessions were retrospectively reviewed. The demographic and clinical characteristics, DVSS, and uroflowmetry parameters were recorded before and after the initial BF sessions. Subsequent treatments after initial BF and clinical responses of patients were noted. RESULTS: Clinical success was observed in one patient by addition of an anticholinergic and in three patients with combination of salvage BF sessions and anticholinergics, whom had predominant overactive bladder (OAB) symptoms. The success rate of TENS alone and in combination with other treatment modalities was 88.8% (8/9 patients). In addition, salvage BF sessions (range 2 to 3) enabled clinical success in five (50%) of 10 cases as a combination with anticholinergics or TENS. In case of incomplete emptying without OAB, adequate clinical response to Botulinum-A was observed during an average follow-up of 29 months in two boys who did not respond to alpha-blockers, even though one required repeat injection after 10 months. The total clinical success rate was 87.5% (14/16 patients) after a median follow-up of 24 months. VV-EBC and Qmax increased by a mean of 30.89% and 7.13 mL/min, respectively, whereas DVSS decreased by a mean of 8.88 points and PVR-EBC decreased by a median of 19.04%. CONCLUSIONS: Our findings showed that clinical success in resistant DV was achieved by various combination treatments in the majority of children. However, a small group may still have persistent, bothersome symptoms despite multiple treatment modalities.

Efficacy of transcutaneous electrical nerve stimulation combined with mirabegron therapy compared with mirabegron monotherapy for overactive bladder: a prospective randomized controlled study.

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).

Effect of Electroacupuncture Combined with Pelvic Floor Muscle Exercise on Urinary Symptoms, Sexual Dysfunction and Pelvic Floor Muscle Strength in Female Patients with Overactive Bladder: A Retrospective Study.

OBJECTIVE: This study aimed to investigate the effect of electroacupuncture combined with pelvic floor muscle exercise in the treatment of female overactive bladder (OAB). METHODS: The clinical data of 134 female patients with OAB admitted to our hospital from April 2022 to June 2023 were retrospectively analysed. The patients were divided into the combination group (n = 74) and the single group (n = 60). The general demographic data, total effective rate, pad weight, female sexual function index (FSFI) score, oxford muscle grading scale and incontinence impact questionnaire short form (IIQ-7) were collected. Propensity score matching (PSM) was used to match the baseline data of the two groups at 1:1 ratio, and t test, chi-square test and analysis of variance were used for calculation. RESULTS: A total of 90 patients were selected after PSM. No significant difference in baseline data was found between the two groups (p > 0.05). Before treatment, no significant difference in FSFI score, oxford muscle grading scale and IIQ-7 score was found between the two groups (p > 0.05). The total effective rate of the combination group was higher than that of the single group (p < 0.05). After 3 weeks and 1 month of treatment, in addition to orgasm and sexual desire, the scores of sexual excitement and sexual satisfaction in the combination group were higher than those in the single group (p < 0.05). The combination group displayed higher oxford muscle grading scale and lower IIQ-7 and pad weight than the single group, and the differences were statistically significant (p < 0.05). CONCLUSIONS: The effect of electroacupuncture stimulation combined with pelvic floor muscle exercise is more significant, which can alleviate urinary symptoms, reduce urine leakage, enhance pelvic floor muscle strength and alleviate sexual dysfunction.

Sacral neuromodulation device biofilm differs in the absence and presence of infection, harbors antibiotic resistance genes, and is reproducible in vitro.

INTRODUCTION/PURPOSE: Sacral neuromodulation (SNM) is effective therapy for overactive bladder refractory to oral therapies, and non-obstructive urinary retention. A subset of SNM devices is associated with infection requiring surgical removal. We sought to compare microbial compositions of explanted devices in the presence and absence of infection, by testing phase, and other clinical factors, and to investigate antibiotic resistance genes present in the biofilms. We analyzed resistance genes to antibiotics used in commercially-available anti-infective device coating/pouch formulations. We further sought to assess biofilm reconstitution by material type and microbial strain in vitro using a continuous-flow stir tank bioreactor, which mimics human tissue with an indwelling device. We hypothesized that SNM device biofilms would differ in composition by infection status, and genes encoding resistance to rifampin and minocycline would be frequently detected. MATERIALS/METHODS: Patients scheduled to undergo removal or revision of SNM devices were consented per IRB-approved protocol (IRB 20-415). Devices were swabbed intraoperatively upon exposure, with controls and precautions to reduce contamination of the surrounding field. Samples and controls were analyzed with next-generation sequencing and RT-PCR, metabolomics, and culture-based approaches. Associations between microbial diversity or microbial abundance, and clinical variables were then analyzed using t-tests and ANOVA. Reconstituted biofilm deposition in vitro using the bioreactor was compared by microbial strain and material type using plate-based assays and scanning electron microscopy. RESULTS: Thirty seven devices were analyzed, all of which harbored detectable microbiota. Proteobacteria, Firmicutes and Actinobacteriota were the most common phyla present overall. Beta-diversity differed in the presence versus absence of infection (p = 0.014). Total abundance, based on normalized microbial counts, differed by testing phase (p < 0.001), indication for placement (p = 0.02), diabetes mellitus (p < 0.001), cardiac disease (p = 0.008) and history of UTI (p = 0.008). Significant microbe-metabolite interaction networks were identified overall and in the absence of infection. 24% of biofilms harbored the tetA tetracycline/minocycline resistance gene and 53% harbored the rpoB rifampin resistance gene. Biofilm was reconstituted across tested strains and material types. Ceramic and titanium did not differ in biofilm deposition for any tested strain. CONCLUSIONS: All analyzed SNM devices harbored microbiota. Device biofilm composition differed in the presence and absence of infection and by testing phase. Antibiotic resistance genes including to rifampin and tetracycline/minocycline, which are used in commercially-available anti-infective pouches, were frequently detected. Isolated organisms from SNM devices demonstrated the ability to reconstitute biofilm formation in vitro. Biofilm deposition was similar between ceramic and titanium, materials used in commercially-available SNM device casings. The findings and techniques used in this study together provide the basis for the investigation of the next generation of device materials and coatings, which may employ novel alternatives to traditional antibiotics. Such alternatives might include bacterial competition, quorum-sensing modulation, or antiseptic application, which could reduce infection risk without significantly selecting for antibiotic resistance.

Outcomes of sequential third-line therapies in patients with refractory overactive bladder.

INTRODUCTION: Sacral neuromodulation (SNM) and onabotulinumtoxinA (BoNTA) injection are third-line therapies for overactive bladder (OAB). Although the efficacy of each third-line treatment has been well established in clinical trials, there is far less information about performing one third-line therapy after the other. Our aim is thus to investigate the outcomes of post-SNM BoNTA and post-BoNTA SNM as "second" third-line treatments. METHODS: We retrospectively reviewed all OAB patients who had both SNM and BoNTA between 2013 and 2022. The primary endpoint was the response rates (>50% improvements) of the second third-line treatments. Secondary endpoints were the proportion of the patients who achieved total dry, the duration of treatments of patients who had significant responses, and risk factors that are associated with treatment response or duration of treatments. RESULTS: A total of 172 patients had two third-line therapies. There were 104 patients who had post-SNM BoNTA and 68 patients who had post-BoNTA SNM. In the post-SNM BoNTA group, 62.5% (65/104) had significant responses after BoNTA treatment. In the post-BoNTA SNM group, 61.8% (44/68) had significant responses after SNM treatment. The proportions of patients who became dry were 21.2% and 23.5%, respectively. In the post-SNM BoNTA group, spinal pathology is associated with a lower probability of a significant response (48.9% vs. 73.7%, p-value = 0.0105). CONCLUSIONS: BoNTA or SNM remains a viable option for refractory OAB after patients fail from one another. Spinal pathology is associated with a poorer response of post-SNM BoNTA.

Multicomponent Intervention Is an Effective Treatment Option for Overactive Bladder in Women.

According to this study: A randomized clinical trial showed that a multicomponent intervention with cognitive components improved health-related quality of life in women with moderate-to-severe overactive bladder.

Outcomes of para-sacral transcutaneous electric nerve stimulation in treatment of primary and refractory overactive bladder among children.

BACKGROUND: Overactive bladder (OAB) is the most prevalent lower urinary tract dysfunction among children. Refractory OAB lacks response to the first line treatments, including anticholinergic, and it is a major clinical challenge. This study aims to compare the efficacy of para-sacral transcutaneous electric nerve stimulation (PS-TENS) in the treatment of primary and refractory OAB among children. METHODS: A prospective, randomized clinical study included 64 children aged 5-12 years with OAB divided equally into two groups: group (1) included 32 children with treatment-naive OAB, while group (2) included 32 children with refractory OAB who failed complete course of anticholinergics. Both groups received PS-TENS three times weekly for 12 weeks. Detailed medical history, voiding diary, ultrasound, and uroflowmetry with EMG were performed at baseline and after 12 weeks of treatment. Filling cystometry was performed for children with refractory OAB before and after PS-TENS. RESULTS: After the end of treatment the number of children with urge incontinence decreased significantly among the two groups: from 25 to 13 and 27 to 15 for the primary and refractory groups, respectively. Micturition frequency per 24 h decreased significantly among children with primary OAB. Bladder capacity increased significantly and the resting detrusor pressure decreased significantly among children with refractory OAB. CONCLUSIONS: PS-TENS is an effective and safe treatment option for children with OAB. The magnitude of improvement is higher among children with primary as compared to refractory OAB.

Acute Autonomic Nervous System Response to Direct Sacral Nerve Root Stimulation in Lower Urinary Tract Dysfunction: A New Approach to Understand the Mechanism of Action of Sacral Nerve Modulation.

PURPOSE: Our goal was to assess acute autonomic nervous system (ANS) response to direct sacral nerve root (SNR) stimulation in the context of lower urinary tract dysfunction. MATERIALS AND METHODS: In this retrospective monocentric study, patients undergoing 2-stage sacral nerve modulation for overactive bladder, nonobstructive urinary retention, or chronic bladder pain syndrome between March 2022 and June 2023 were analyzed. A standardized stimulation protocol was applied during the lead implantation, each of the 4 contact points being sequentially stimulated at the amplitude required to elicit anal motor response. Stimulations were labeled as StimA, StimB, StimC, and StimD, ordered by ascending order of minimum amplitude required for anal motor response. Heart rate variability parameters were collected using PhysioDoloris Monitor, and computed through the time-domain (standard deviation of normal-to-normal intervals [SDNN], root mean square of successive differences), the frequency-domain (low frequency, high frequency) and the graphical (Analgesia Nociception Index [ANI]) methods. RESULTS: Fifty patients were analyzed, including 35 females. Twelve patients had an underlying neurological disease. Efficacy was deemed achieved in 54% of patients. SDNN variability significantly increased during StimA to StimC, while maximum SDNN significantly increased only during StimA. ANI variability significantly increased during all 4 stimulations, while maximum ANI significantly increased only during StimA. CONCLUSIONS: Direct stimulation of SNR is responsible for a significant increase in ANS and relative parasympathetic nervous system activity, with a greater effect observed when the stimulation was delivered closer to the SNR. These results shed light on potential mechanisms underlying sacral nerve modulation, particularly regarding the treatment of ANS dysregulation in lower urinary tract dysfunction.

Tibial Nerve Stimulation for Urge Urinary Incontinence and Overactive Bladder: Narrative Review of Randomized Controlled Trials and Applicability to Implantable Devices.

The tibial nerve is an established target for neuromodulation in the management of overactive bladder (OAB) and its associated symptoms, including urge urinary incontinence (UUI). Technologies are currently available to deliver tibial nerve stimulation (TNS) through percutaneous devices or through implantable devices. The benefits and safety of percutaneous TNS have led to it as a guideline-recommended therapy. However, patient compliance is limited by the burden of weekly office visits and the need for maintenance treatments. Further, insurance often only covers a limited number of lifetime visits for percutaneous TNS. These factors and others have led to the development, study, and utilization of implantable TNS devices. Implantable TNS devices deliver the same therapeutic mechanism of action for nerve stimulation with a permanent implanted device that provides at-home stimulation rather than in-office therapy delivery. Additionally, there is an added potential for dynamic and patient-centered stimulation. There is a large body of high-quality evidence published for TNS, including numerous randomized controlled trials published on percutaneous TNS which have consistently demonstrated superior efficacy to sham and similar efficacy to that of anticholinergic medications. Percutaneous TNS also performs better than conservative therapy including pelvic floor muscle training. The percutaneous and implantable approaches deliver nerve stimulation to the same target nerve, using the same mechanism of action. Therefore, data from randomized trials of percutaneous TNS are informative for implantable TNS devices. At the time of this article's publication, at least two implantable TNS devices have received marketing authorization from the Food and Drug Administration (FDA). The objective of this review is to discuss the mechanism of action for TNS and summarize the published literature from clinical trials of percutaneous TNS as a foundation of high-quality evidence for implantable devices targeting the tibial nerve.

Low-Intensity Extracorporeal Shock Wave Therapy Ameliorates Detrusor Hyperactivity with Impaired Contractility via Transient Potential Vanilloid Channels: A Rat Model for Ovarian Hormone Deficiency.

This study explores low-intensity extracorporeal shock wave therapy (LiESWT)'s efficacy in alleviating detrusor hyperactivity with impaired contractility (DHIC) induced by ovarian hormone deficiency (OHD) in ovariectomized rats. The rats were categorized into the following four groups: sham group; OVX group, subjected to bilateral ovariectomy (OVX) for 12 months to induce OHD; OVX + SW4 group, underwent OHD for 12 months followed by 4 weeks of weekly LiESWT; and OVX + SW8 group, underwent OHD for 12 months followed by 8 weeks of weekly LiESWT. Cystometrogram studies and voiding behavior tracing were used to identify the symptoms of DHIC. Muscle strip contractility was evaluated through electrical-field, carbachol, ATP, and KCl stimulations. Western blot and immunofluorescence analyses were performed to assess the expressions of various markers related to bladder dysfunction. The OVX rats exhibited significant bladder deterioration and overactivity, alleviated by LiESWT. LiESWT modified transient receptor potential vanilloid (TRPV) channel expression, regulating calcium concentration and enhancing bladder capacity. It also elevated endoplasmic reticulum (ER) stress proteins, influencing ER-related Ca2+ channels and receptors to modulate detrusor muscle contractility. OHD after 12 months led to neuronal degeneration and reduced TRPV1 and TRPV4 channel activation. LiESWT demonstrated potential in enhancing angiogenic remodeling, neurogenesis, and receptor response, ameliorating DHIC via TRPV channels and cellular signaling in the OHD-induced DHIC rat model.

The effect of pelvic floor muscle training in men with benign prostatic hyperplasia and overactive bladder.

BACKGROUND: Men with overactive bladder (OAB) and benign prostatic hyperplasia (BPH), will have deterioration in the quality of life. OBJECTIVE: The aim of this study was to evaluate the effect of combining pelvic floor muscle training with the urgency suppression technique (PFMT-st) and silodosin in comparison with silodosin in men with benign prostatic hyperplasia (BPH) and overactive bladder (OAB) after 12 weeks of treatment. PATIENTS AND METHODS: A total of 158 patients were randomized into two groups. The control group received oral silodosin at a daily dose of 8 mg. The experimental group was administered PFMT-st and silodosin. The evaluation methods included the number of voids and intensity of urgencies over 24 h using a micturition diary, the International Prostate Symptom Score (IPSS), the Overactive Bladder Questionnaire (OAB-q), and the patient global impression of improvement (PGI-I). RESULTS: 142 of 172 (86.6%) men were assessed (70 in the control group, 72 in the experimental group). The significant changes were in favor of the experimental group (p < 0.001) in the number of voids per 24 h (- 1.95 ± 1.94 vs. - 0.90 ± 1.44), the OAB-q symptom score (- 14.25 ± 10.05 vs. - 9.28 ± 10.60), the intensity of urgencies (- 0.97 ± 0.53 vs. 0.24 ± 0.57), the IPSS (- 4.59 ± 3.00 vs. - 2.30 ± 3.63), and in the PGI-I (2.24 ± 0.79 vs. 3.60 ± 0.92). CONCLUSIONS: The addition of PFMT-st to silodosin treatment significantly improved OAB in men with BPH. This is the first study to confirm that PFMT-st should be the first-choice treatment for OAB in BPH.
