Comparing Conventional and High-Voltage Long-Duration Pulsed Radiofrequency of the Pudendal Nerve in Pudendal Neuralgia Treatment: A Randomized Controlled Trial

What this Trial Is About

Researchers are evaluating two types of pulsed radiofrequency (PRF) treatments for people with pudendal neuralgia, a chronic nerve pain affecting the pelvic area and perineum. This randomized controlled trial compares conventional PRF with high-voltage long-duration PRF to assess their effects on pain relief, function, and safety. The trial is conducted at a single center and follows standard clinical safety procedures to protect participants. Participants are randomly assigned to receive either conventional PRF applied at 42°C for 360 seconds or high-voltage long-duration PRF applied at 42°C for up to 900 seconds, with voltage adjusted from 40V to a patient-tolerated maximum of 90V. Both procedures are performed under sterile conditions with patients positioned prone, using fluoroscopic guidance and monitoring of vital signs. If symptoms affect both sides, treatments are done sequentially. During the study, participants will be assessed at baseline and at 1, 3, and 6 months for pain intensity using the Numeric Rating Scale, functional improvement, patient satisfaction, and quality of life through the Short Form-36 questionnaire. Researchers will also monitor adverse events throughout the study period. Treatments and follow-up visits involve standard clinical procedures to ensure patient safety and accurate data collection.
