We present a rare postoperative complication, that is, pseudodiverticulum urethral formation, which occurred after a laparoscopic radical prostatectomy with nerve-sparing procedure carried out with the placement of Hem-o-lok? in the latero-prostatic pedicles in a patient with clinically localized prostate cancer. Consequently, these devices should be used with caution in the region of the vesicourethral anastomosis.
