Anatomic basis for the continence-preserving radical retropubic prostatectomy release_evb3ae72m5b6bb57vnpu6j6vae

Abstract

The technique of continence-preserving anatomic radical retropubic prostatectomy focuses on the preservation of the following anatomic components of the external striated urethral sphincteric complex: (1) the entire circumference of the rhabdosphincter musculature, (2) the periurethral fascial investments (the pubourethral ligaments anterolaterally and median fibrous raphe posteriorly), and (3) the innervation of both the rhabdosphincter by way of the intrapelvic branch of the pudendal nerve (somatic) and the mucosal and smooth muscle components by way of the urethral branch of the inferior hypogastric plexus (autonomic). The clinical impact of preserving the external striated urethral sphincter and its innervation by performing a continence preserving anatomic retropubic prostatectomy is a shorter time to achieve urinary continence.
