[Vesicourethral anastomotic stricture after radical prostatectomy secondary to migration of a metal clip].

The frequency of vesicourethral anastomotic stricture after prostatectomy is estimated to be 14%, an average of 3 months after the operation. The authors report the cases of a 61-year-old man undergoing radical prostatectomy for localized prostate cancer. The postoperative course was marked by recurrent urinary retention and several urethrotomies failed to restore spontaneous voiding. A clip was finally visualized and removed by endoscopy. The patient has not experienced any further episodes of retention. This is the first published cases of clip migration responsible for anastomotic stricture after radical prostatectomy. This diagnosis must be considered in the case of repeated postoperative retention.
