Intravesical migration and spontaneous expulsion of a Hem-o-lok polymer ligating clip after laparoscopic radical prostatectomy.

We present a rare postoperative complication occurring after a laparoscopic radical prostatectomy with nerve-sparing procedure carried out with the placement of 3 Weck Hem-o-lok-L clips in the right neurovascular bundle, in a patient with clinically localized prostate cancer. The procedure was completed without any complications and the urethral catheter was removal at 15 days. We report a case of intravesical migration and subsequent calculus formation with spontaneous expulsion of Hem-o-lok clip. To date, this is the only reported case of intravesical migration and subsequent calculus formation with a spontaneous expulsion.
