Inferior hypogastric plexus blockade versus acupuncture for the management of idiopathic chronic pelvic pain: A randomized clinical trial

Background: To compare the clinical efficacies of inferior hypogastric plexus blockade and acupuncture in the management of idiopathic chronic pelvic pain (CPP). Methods: The study included 117 patients with CPP. Group 1 included 62 patients who underwent inferior hypogastric plexus blockade and group 2 included 55 patients who underwent acupuncture. Pain level was assessed using a visual analogue scale (VAS) immediately and at 2, 6, and 12 weeks after treatment. Results: The preprocedure VAS score was 7.6 ± 0.15 in group 1 and 7.7 ± 0.24 in group 2 ( p > 0.05). Pelvic pain decreased significantly in both groups after treatment, with pretreatment and posttreatment scores of 7.6 ± 0.15 and 2.2 ± 0.88, respectively, in group 1 ( p p p p = 0.3737). Patients who did not benefit from the treatment were significantly more in group 2 than in group 1 (25.5% vs. 6.5%, p = 0.0294). No complications were reported in both groups. Conclusion: The study results showed that inferior hypogastric blockade had a 72.6% success rate and showed a significantly higher effect on reducing pain intensity in a short period of time in the management of CPP, compared to acupuncture.
