Funneling of the bladder neck - radiological appearance after radical retropubic prostatectomy and clinical relevance

摘要

Several authors have commented on the anatomical changes following radical prostatectomy (RP) for prostate cancer and their characteristic radiological appearances. , Most of these relate to periurethral fibrosis and its clinical significance in patients with postprostatectomy sphincter weakness incontinence. , On magnetic resonance imaging (MRI), this postsurgical fibrosis appears as a focus of low-signal intensity in the periurethral tissues at and around the level of the vesicourethral anastomosis (VUA) which is appreciable on both T1- and T2-weighted images.
