摘要
Several authors have commented on the anatomical changes following radical prostatectomy(RP)for prostate cancer and their characteristic radiological appearances.1,2 Most of these relate to periurethral fibrosis and its clinical significance in patients with postprostatectomy sphincter weakness incontinence.3,4 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.
