Summary

This study is a single-center, prospective, randomized controlled trial evaluating two types of pulsed radiofrequency (PRF) treatment for patients with pudendal neuralgia. Pudendal neuralgia is a chronic neuropathic pain affecting the perineum and pelvic area, often causing significant discomfort and reduced quality of life.

Patients will be randomly assigned to receive either conventional PRF or high-voltage long-duration PRF applied to the pudendal nerve. The study aims to compare the clinical effectiveness, pain relief, and safety of the two treatment approaches. Participants will be monitored for pain improvement, functional outcomes, and any treatment-related side effects.

The study follows standard clinical procedures and all treatments are performed under sterile conditions with proper monitoring to ensure patient safety.

PROCEDURE

Intervention Type * Select the type of intervention. Procedure / Surgery Intervention Name * Enter a brief, descriptive name for the intervention. Use a non-proprietary (generic) name, if available

Conventional pulsed radiofrequency (PRF) is applied to the pudendal nerve at 42°C for 360 seconds, with a pulse frequency of 2 Hz and pulse width of 20 ms. The procedure is performed under sterile conditions in the operating room with patient monitoring (blood pressure, pulse, ECG, oxygen saturation). Patients are positioned prone, the target site is sterilized, and the PRF needle is placed under fluoroscopic guidance. Bilateral symptoms are treated sequentially if present.

PROCEDURE

High-Voltage Long-Duration Pulsed Radiofrequency

High-voltage long-duration pulsed radiofrequency (PRF) is applied to the pudendal nerve at 42°C for 900 seconds, with a pulse frequency of 2 Hz and pulse width of 20 ms. The voltage is titrated from 40V to a patient-tolerated maximum of 90V. The procedure is performed under sterile conditions in the operating room with patient monitoring (blood pressure, pulse, ECG, oxygen saturation). Patients are positioned prone, the target site is sterilized, and the PRF needle is placed under fluoroscopic guidance. Bilateral symptoms are treated sequentially if present.
