Pudendal Nerve Pulsed Radiofrequency and Block

Pudendal nerve pulsed radiofrequency is an option for selected patients with persistent pudendal neuralgia or neuropathic pelvic pain who have obtained meaningful but temporary relief from a pudendal nerve block. The aim is to reduce abnormal pain signalling from the affected nerve while avoiding destructive thermal ablation.

The procedure is performed with image guidance to position a specialised needle close to the pudendal nerve. Local anaesthetic may be injected around the nerve, followed by controlled pulsed radiofrequency stimulation. The treatment uses short bursts of electrical energy rather than continuous high-temperature radiofrequency, and careful testing is used to confirm the position before treatment.

Improvement may occur gradually and the duration of benefit varies. Some patients obtain relief for months, while others have a shorter or limited response. The treatment is generally used alongside pelvic rehabilitation and other measures addressing the underlying cause of pain, with repeat treatment considered only when the initial response supports it.
