简要总结
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.
详细描述
This single-center, prospective, randomized controlled trial aims to compare the clinical effectiveness and safety of conventional pulsed radiofrequency (PRF) versus high-voltage long-duration PRF applied to the pudendal nerve in patients with pudendal neuralgia.
Eligible patients will be randomly assigned to one of the two intervention groups. Conventional PRF will be applied at 42°C for 360 seconds, while high-voltage long-duration PRF will be applied at 42°C for up to 900 seconds, with voltage titrated from 40V to a patient-tolerated maximum of 90V. All procedures are performed under sterile conditions in an operating room with patient monitoring (blood pressure, pulse, ECG, and oxygen saturation).
Patients will be assessed for pain intensity, functional improvement, and adverse effects at scheduled follow-up visits. Bilateral symptoms will be treated sequentially if present. The study adheres to standard clinical safety procedures and no additional risk beyond routine clinical care is anticipated.
