Core Tip
Core tip: This study prospectively evaluated the anal sphincter morphology and function of chronic proctalgia (CP) in female patients by three-dimensional endoanal ultrasound. Here, we employed puborectalis angle to assess the paradoxical contraction of the puborectalis muscle (PR) in CP. The PR thickness and paradoxical contraction of PR are associated with CP, which may be promising diagnosis factors for CP.
