Combined PRF of the Pudendal Nerve With Ganglion Impar Block Effectively Alleviates Pudendal Neuralgia

Not Applicable

Recruiting

• Conditions: Pulsed Radiofrequency; Pudendal Neuralgia
• Interventions: Procedure: Combined pulsed radiofrequency of the pudendal nerve with ganglion impar block

• Registration Number: NCT06461312
• Lead Sponsor: Peking University People's Hospital

Brief Summary

Patients with pudendal neuralgia suffer from long-term pain, which severely affects their quality of life. Due to unclear etiology, there is a lack of specific treatment methods. The aim of this study is to evaluate the efficacy of combined pulsed radiofrequency with ganglion impar block therapy helps evaluate the effectiveness of this treatment method for pudendal neuralgia, comparing it with traditional treatments or single interventions, and providing guidance for clinical practice.

Detailed Description

We plan to enroll patients with pudendal neuralgia .Pre-treatment, we collected data including pain assessment, anxiety, depression, catastrophizing, and pain sensitivity scales. Treatment involved ultrasound-guided pudendal nerve pulsed radiofrequency and X-ray-guided ganglion impar block. The Patient Global Impression of Change (PGIC) and Numeric Rating Scale (NRS) were used as the main observation indicators to evaluate the treatment effect at 1, 2, 3, and 6 months postoperatively, followed by correlation analysis with the scores of relevant scales.
