Summary

This trial aims to compare two methods of treating chronic pelvic pain caused by pudendal neuralgia. One method involves a transvaginal finger-guided pudendal nerve block, while the other

Who is the study for?
This trial is for individuals experiencing chronic pelvic or urogenital pain, diagnosed with pudendal neuralgia. It's aimed at those who have not found relief from other treatments and are suitable candidates for nerve block procedures.
What is being tested?
The study compares two methods of administering a pudendal nerve block to relieve pelvic pain: one using transvaginal finger guidance and the other using fluoroscopy (a type of X-ray) for guidance through the gluteal area.
What are the potential side effects?
Possible side effects include discomfort at injection site, allergic reactions to bupivacaine, temporary numbness in the pelvic region, bleeding, infection risk at the puncture site, and potential worsening of symptoms.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Transvaginal pudendal nerve blockExperimental Treatment1 Intervention
Participants in this arm will receive 10 mL bupivacaine injected into bilateral pudendal nerves via transvaginal approach. This is performed by palpating 1 cm superior and medial to the ischial spine. Participants will receive an injection each 2 weeks, for a total of 3 injections over 6 weeks.
Group II: Fluoroscopy guided pudendal nerve blockExperimental Treatment1 Intervention
Participants in this arm will receive 5 mL bupivacaine injected into bilateral pudendal nerves via fluoroscopic guided trans gluteal approach. They will receive one injection over the 6-week duration.
