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.

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.

3. Received conservative treatment for more than 3 months, and either had poor response to conservative treatment or intolerable medication side effects.
