Chronic pelvic pain of unknown origin may be caused by loose uterosacral ligaments failing to support pelvic nerve plexuses - a critical review.

Introduction: Chronic pelvic pain of unknown origin (CPPU) affects the quality of life (QoL) of up to 20% of women. The 2005 Cochrane Review, based on randomized controlled trials (RCTs), stated that the pathogenesis of CPPU is poorly understood and its treatment is empirical and ineffective. Totally ignored were the high cure rates from uterosacral ligament (USL) repair, the principal subject of this review.
