Defining the Safety and Efficacy of POSterIor Tibial NeRve StimulatiON in Children

The purpose of this study is to find out if overactive bladder (OAB) can be safely treated by stimulating a nerve near the ankle. This procedure is called percutaneous tibial nerve stimulation (PTNS). It will be done by a device called the Urgent PC. The Urgent PC works by sending weak electrical signals through a thin needle to the nerve near the ankle. Stimulating this nerve may change bladder control.

Impact of TTNS on Bladder Symptoms Among People With MS, A RCT

Background: Neurogenic lower urinary tract dysfunction is common among people with multiple sclerosis (MS). Recent studies showed that bladder storage symptoms are predominant among MS with a pooled prevalence of frequency at 73.45% followed by urgency at 63.87%. Transcutaneous tibial nerve stimulation (TTNS) is a non-invasive treatment to manage bladder storage symptoms; however, the effectiveness of TTNS is based on a small number of studies with the absence of high-quality evidence. This study aims to investigate the effectiveness of TTNS on bladder storage symptoms compared with sham TTNS among people with MS.Methods: The investigators will use a randomised sham controlled double blind study to explore the effectiveness of TTNS in the treatment of bladder storage symptoms in MS. the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) was followed to standardize the conduct and reporting of the current protocol. The recruitment plan is twofold: 1) Open recruitment for people with MS through King Fahd Hospital of the University communication channels; 2) people with any type of MS attending their routine appointments in MS clinic at King Fahd Hospital of the University, Al Khobar. The investigators will investigate the effectiveness of TTNS compared to sham TTNS on bladder storage symptoms and the effect on quality of life using ICIQ-OAB, ICIQ 3-day bladder diary, ICIQ-LUTS qol, and PSQI. Participant's perception of change post intervention will be evaluated using GPE. Outcomes will be measured at 0, 6 weeks and at 6 months post intervention. A sample size of 72 patients (36 in each group) is required to achieve 90% power with two-tailed tests at an alpha level of 0.05. Conclusion: Multiple sclerosis is a long-term condition, and self-management is important. TTNS provide a safe, non-invasive intervention that can be administered at home. Should the trial determine that TTNS is effective compared to sham TTNS, the investigators will plan to integrate TTNS into standard clinical care pathways in MS.

Randomized Controlled Trial Comparing Low Dose Tadalafil Versus Solifenacin For Management of Overactive Bladder in Women: Multicenter Egyptian National Study

Researchers are studying two medicines to see which works better for women with overactive bladder (OAB). OAB causes sudden urges to urinate, frequent bathroom trips, and sometimes leakage. Women who join the study will be randomly placed into one of two groups: One group will take tadalafil (5 mg), a medicine taken once a day. The other group will take solifenacin (5 mg), a common treatment for OAB, also taken once a day. The study will last 12 weeks. Participants will keep a bladder diary, answer short questionnaires, and have simple urine flow and bladder tests at several visits. The main goal is to find out which medicine lowers OAB symptoms more, such as urgency and frequent urination. Researchers will also look at quality of life, bladder function, and side effects. Women aged 18 to 75 years with OAB symptoms for at least 3 months may be able to take part.

Improving Overactive Bladder Treatment Access and Adherence

Overactive bladder (OAB) and urinary incontinence (UI) are chronic debilitating and embarrassing conditions that affect 33 million Americans. Yet, both are underdiagnosed and undertreated with significant financial and health-related consequences. OAB syndrome is characterized by urinary urgency, with and without urinary incontinence, urinary frequency, and nocturia. Evidence-based treatments are available, including behavioral therapy, pharmacotherapy, and minimally invasive procedures. Diagnosis and treatment are also associated with improvement in urinary symptoms and overall quality of life (QOL).3 However, 70-80% of treated patients will discontinue use of therapy in the first year due to one of several factors (e.g., cost, tolerability, inadequate effect). In addition, only 4.7% progress to advanced therapies suggesting undertreatment for those that need it most. Vulnerable populations are especially at risk, as therapy utilization are lowest among older, lower income, and/or minority groups. Poor access, insufficient patient education regarding disease chronicity, expected outcomes, costs, and potential side effects lead to unrealistic patient perceptions about therapy. This leads to suboptimal therapy duration, poor treatment efficacy, adherence, and undertreatment. The study aims to evaluate a tailored patient-centered tool to begin the treatment process.

Oral Lactobacillus Supplementation as Treatment for Overactive Bladder Syndrome: A Randomised Controlled Trial

Background: Overactive bladder describes a syndrome characterized by frequent urges to urinate and increased urination with or without nocturia and with or without urinary incontinence. Overactive bladder affects approximately 13% of older women and thus represents a condition with high prevalence. Affected women report significant limitations in daily life, as well as social isolation. Despite the high occurrence of this condition, therapeutic options are limited, partly because the etiology of this condition is not fully understood. Increasingly, studies suggest an imbalance in the urogenital microbiome as a possible cause of the development of the condition. Therefore, the aim of this study is to test, whether the oral administration of a lactobacillus preparation can lead to a reduction in symptoms. Design: Randomized controlled study Methods: Intake of OMNi BiOTiC® 41167 or placebo twice daily for 6 months; swabs (vaginal and urethral) and urine samples from a single-use catheter for microbiome determination at 0, 3, and 7 months. Outcome: Reduction of subjective symptoms (yes/no) after 3 and 7 months; reduction of Overactive Bladder Symptom Score after 3 and 7 months; change in the urogenital microbiome after 3 and 7 months (comparison of intervention vs. placebo).

Platelet-Rich Plasma Versus Botulinum Toxin for Refractory Overactive Bladder: A Randomized Trial

Overactive bladder is a common condition that causes sudden urges to urinate, frequent urination, night-time urination, and sometimes leakage of urine. Many people with overactive bladder improve with lifestyle changes and medicines. However, some patients do not respond to these standard treatments and continue to suffer from bothersome symptoms. This study is designed to help patients who have not improved with available medical therapy. Two treatments will be compared in this research. The first treatment uses platelet-rich plasma. Platelet-rich plasma is made from a patient's own blood and contains growth factors that may help repair the lining of the bladder and improve bladder function. The second treatment uses botulinum toxin. Botulinum toxin is a protein that can reduce unwanted bladder contractions and is already approved for use in patients with overactive bladder who did not respond to other treatments. The purpose of this study is to evaluate whether platelet-rich plasma injection into the bladder wall is safe, effective, and durable when compared with botulinum toxin injection into the bladder muscle. We believe that platelet-rich plasma may improve bladder health by encouraging tissue repair and reducing inflammation, while botulinum toxin may reduce bladder overactivity by blocking chemical signals that cause muscle contractions. This study will take place at Benha University Hospital in Egypt. About 48 adult participants with overactive bladder that has not improved after at least six months of medical therapy will be enrolled. Participants will be randomly assigned to one of two groups. One group will receive platelet-rich plasma injections into the bladder lining, and the other group will receive botulinum toxin injections into the bladder muscle. The procedures will be performed under anesthesia using a cystoscope, which is a thin instrument inserted into the bladder. Participants will be followed for one year. At several time points during follow-up, they will complete bladder symptom questionnaires, keep a voiding diary, and undergo urodynamic studies to measure bladder capacity and function. Researchers will also monitor safety by recording any side effects, such as urinary tract infections or temporary difficulty emptying the bladder. The main goal of this study is to determine whether platelet-rich plasma can reduce symptoms of overactive bladder as effectively as botulinum toxin, with fewer side effects and longer-lasting results. If successful, platelet-rich plasma could offer a new treatment option for patients who continue to struggle with overactive bladder despite standard medical therapy.

Transcutaneous Tibial Nerve Stimulation for Overactive Bladder Syndrome and Associated Gait Changes in Post-menopausal Women

The goal of this clinical trial is to learn if surface tibial electrical stimulation (mild electrical signals on the inside of the ankle) helps women 60 years or older with urine leakage that happens on the way to the bathroom or at night time. The main questions it aims to answer are: 1). How many treatments per week over a 12-week period improve a person\'s bladder symptoms?; 2). Is a person more confident that they will not fall and / or leak urine on the way to the bathroom after the treatment with the electrical stimulation treatments; 3). Does the way a person walks when they need to go to the bathroom change after they have had the electrical stimulation? They will visit the clinic 3 times to complete several questionnaires and walk with a full bladder and empty bladder. On the first visit, the participant will be taught how to use the electrical stimulation device. Participants will either receive the treatment 2 or 4 times per week for 12 weeks or no treatment with the option to receive treatment following the 12 weeks. Participants will be given a bladder diary to complete at the start of treatment, at 6 weeks, then at 12 weeks and will be instructed in completion. They will drink water until they have a strong urge to urinate, then will walk along an electronic pathway and will go empty their bladder. After emptying, they will walk back along the electronic pathway again. They will also complete a Timed Up and Go test - stand up from a chair, walk 3 meters, then turn around, walk back, then sit down. At the 6th week follow up and the 12th week follow up, they will complete each questionnaire again and complete the walking tasks again.
