Abstract
Although it is known that changes in bacterial components of the urinary microbiome are associated with overactive bladder (OAB), the specific role of viruses is still insufficiently investigated. The aim of the present study is to evaluate the role of urinary viruses in woman with OAB, and analyze the potential relationship between viruses, bacteria and disease. Catheterized urine samples were collected from 55 women with OAB and 18 control individuals. OAB patients fulfilling the following criteria were considered eligible for this study: female, 18 years of age or older; presented with classic OAB symptoms defined by the International Continence Society; and OAB Symptom Score (OABSS) total score ≥ 3 points and question 3 (urgency) score ≥ 2 points. Based on results of metagenomic next-generation sequencing (mNGS), all participants were divided into virus-infected and virus-uninfected groups for analysis. The results of mNGS showed that the diversity of the OAB group was lower than that of the control group when focused on bacterial sequences, which was consistent with our previous study. According to the questionnaire filled out by the patients, OABSS and 8-item OAB questionnaire, female OAB patients who had viruses detected in their urine had more severe symptoms. In parallel, John Cunningham virus (mainly subtype 7 and subtype 2) was the most frequently detected virus in urine. Correlation analysis indicated that risk factors for virus infection in OAB patients include age, habit of holding urine and pelvic surgery history. Given our preliminary data, viral infection can aggravate OAB severity and affect the composition of bacterial. Further research is required to explain how viral infections can aggravate OAB patient symptoms and cause bacterial changes.

Posterior Tibial Nerve Stimulation for Overactive Bladder: Mechanism, Classification, and Management Outlines. PARKINSON'S DISEASE 2022; 2022:2700227. [PMID: 35400016 PMCID: PMC8984064 DOI: 10.1155/2022/2700227] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 01/28/2022] [Indexed: 12/02/2022]
Abstract
Purpose of the Review. Posterior tibial nerve stimulation (PTNS) techniques have dramatically grown after approval to manage overactive bladder (OAB). The present review will focus on the most current data on PTNS types (percutaneous, transcutaneous, and implant) and their mechanism of action, safety, efficacy, advantages, drawbacks, limitation, and clinical applications. Recent Findings. The present review described the recent studies that addressed the tibial nerve stimulation role in OAB management. BlueWind RENOVA system, Bioness StimRouter, and eCoin are examples of emerging technologies that have evolved from interval sessions (percutaneous PTNS and transcutaneous PTNS) to continuous stimulation (implants). These can be efficiently managed at home by patients with minimum burden on the health system and fewer visits, especially in the COVID-19 pandemic. Summary. Our review shows that the tibial nerve stimulation advancements in OAB treatment have been rapidly increasing over the recent years. It is minimally invasive and effective, similar to sacral nerve stimulation (SNM), but less aggressive. Implantable PTNS has been promised in terms of efficacy, safety, and high acceptance rate. However, evidence is still limited to short-term trials, and tolerability, method, and drawbacks remain challenges.

Percutaneous tibial nerve stimulation versus sham efficacy in the treatment of refractory overactive bladder: outcomes following a shortened 6-week protocol, a prospective randomized controlled trial. Int Urol Nephrol 2021; 53:2459-2467. [PMID: 34601705 DOI: 10.1007/s11255-021-02999-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 09/19/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE It is a prospective randomized controlled trial comparing the efficacy of percutaneous tibial nerve stimulation versus sham for a shortened 6-week protocol of treatment in management of refractory OAB in non-neurogenic adult patients. METHODS A total of 50 adults with refractory non-neurogenic overactive bladder symptoms were randomized 1:1 to 6 weeks of treatment with weekly percutaneous tibial nerve stimulation or sham therapy. Overactive bladder symptom score as well as 3-day voiding diaries were completed at baseline and at 7th week, 3rd and 6th month. RESULTS The 7th week, 3rd and 6th month symptom score assessment for overall bladder symptoms demonstrated that percutaneous tibial nerve stimulation patients achieved statistically significant improvement in bladder symptoms with 52% reporting moderately improved responses compared to non-response of sham patients from baseline (P = 0.001). Voiding diary parameters after 6 weeks of therapy showed that PTNS patients had statistically significant improvements in frequency, voided volume and urgency urinary incontinence episodes compared to sham. No serious device-related adverse events or malfunctions were reported. CONCLUSION A shortened 6-week treatment protocol with PTNS appears to be successful and more effective than sham in the treatment of refractory OAB. PTNS therapy is safe and effective in treating OAB symptoms with 52% success rate following a shortened 6-week protocol. The duration of treatment with PTNS can be halved compared to the conventional 12 weeks, which would make it more acceptable and cost effective for patients.

Front Surg 2021; 8:670123. [PMID: 34336915 PMCID: PMC8316598 DOI: 10.3389/fsurg.2021.670123] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 06/16/2021] [Indexed: 12/22/2022] Open
Abstract
Background: This study aimed to evaluate the clinical efficacy of Yun-type optimized pelvic floor training therapy for middle-aged women with severe overactive bladder (OAB). Methods: This randomized, observer-blinded, parallel-group controlled clinical trial included 108 middle-age women with severe OAB and assigned them to the intervention group (treated with combination of Yun-type optimized pelvic floor training with solifenacin for 12 weeks) and control group (treated with solifenacin for 6 weeks and, after 2 weeks of elution, received the combination of Yun-type optimized pelvic floor training and solifenacin for 6 weeks). The outcomes associated with OAB, pelvic floor muscle (PFM) function, and sexual function were compared after 6 and 12/14 weeks of treatment. Results: The primary variables were OAB-associated outcomes, including overactive bladder symptom score (OABSS), urgent urination, urine, nocturia, urge urinary incontinence, patient's perception of bladder condition, urogenital distress inventory-6, incontinence impact questionnaire-7, voiding volume, average flow rate, and maximum flow rate. The secondary variables were indicators related to PFM function and sexual function. These indicators were significantly improved in both groups after interventions. Notably, the improvements in most of these indicators were superior in the intervention group than in the control group after 6 weeks and 12/14 weeks of treatment. Conclusions: The use of Yun-type optimized pelvic floor training adds to the benefits of solifenacin regarding severe OAB-associated outcomes, PMF function, and sexual function in middle-aged women with severe OAB. Combining Yun-type optimized pelvic floor training with traditional drug therapies may improve clinical outcomes in patients with severe OAB. Trial Registration: ChiCTR-INR-17012189.

Abstract
INTRODUCTION AND HYPOTHESIS Unsatisfactory treatment outcome sometimes is described as frequently occurring in patients treated with first-line therapy for overactive bladder (OAB). The present article reviews the different circumstances which may result in failure to respond to lifestyle interventions, behavioral therapy, and/or antimuscarinic treatment. METHODS An extensive literature search was conducted to identify relevant articles on pathophysiological, clinical, and pharmacological aspects of refractory OAB. RESULTS Missing definition, unrealistic individual expectation of treatment outcomes, lack of communication between physician and patient as well as pathophysiological and pharmacological processes were identified as relevant for failure to respond to first-line OAB treatment. Increase of patient's motivation to adhere to the prescribed treatment, critical examination of the patient in regard to the initial diagnosis, and individual adjustment of antimuscarinic therapy may be appropriate tools to improve treatment outcome in OAB patients. CONCLUSIONS Overall, the incidence of refractory OAB seems to be overestimated. There are several approaches to improve therapy results.
