Low-Intensity Shock Wave Therapy for Refractory Overactive Bladder in Women
Egypt40 participantsStarted 2026-08-01
Plain-language summary
Overactive bladder is a condition characterized by a sudden and difficult-to-control need to urinate, which may occur with frequent urination, nighttime urination, and urine leakage. Some women continue to experience these symptoms despite lifestyle changes, behavioral therapy, and medication, or they cannot tolerate or decline medical treatment.
This study will evaluate whether low-intensity extracorporeal shock wave therapy (Li-ESWT), a non-surgical treatment delivered externally over the lower abdomen, can safely improve refractory overactive bladder symptoms in women.
A total of 40 women will be randomly assigned in equal numbers to receive either active Li-ESWT or a sham treatment. Both groups will attend one treatment session each week for six weeks. The sham procedure will be similar to the active treatment in positioning, session duration, and device sound but will not deliver shock wave energy.
Symptoms will be assessed using the validated Arabic version of the 8-item Overactive Bladder Questionnaire (OAB-V8) before treatment and during follow-up. The main purpose of the study is to compare the change in OAB-V8 symptom score between the two groups after one month. Additional assessments at three months will include post-void residual urine volume, information from a 3-day voiding diary, the participant's overall impression of improvement, and any treatment-related adverse events.
The study hypothesis is that Li-ESWT will improve overactive bladder symptoms and quality of life compared with sham treatment.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
