Transvaginal Versus Fluoroscopy-guided Trans Gluteal Pudendal Nerve Block for Pudendal Neuralgia
United States40 participantsStarted 2024-06-27
Plain-language summary
Chronic pain affecting the pelvic and urogenital area is a major clinical problem and can have a profound impact on quality of life and health care costs. Pelvic pain arising from entrapment or neuropathy of the pudendal nerve is known as pudendal neuralgia, which results in chronic perineal pain. This pain syndrome is difficult to diagnose and patients with pudendal neuralgia may present to providers with refractory chronic pelvic pain. Pudendal nerve infiltration or pudendal nerve block (PNB) serves as a diagnostic tool and treatment modality for patients with this condition. To date, there are no published randomized controlled trials comparing imaging-guided PNB to transvaginal finger-guided PNB. While one can assume that image-guided nerve blocks will provide better accuracy for injection and potentially better efficacy in pain relief as a result, no published data exists comparing the outcomes and efficacy between modalities.
The purpose of this prospective, non-inferiority, randomized controlled trial is to compare the efficacy of pain relief from bilateral transvaginal finger-guided pudendal nerve block versus bilateral fluoroscopy-guided trans gluteal pudendal nerve block for patients with pudendal neuralgia.

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.
