Posterior urethra injuries

The membranous urethra can be separated from the prostate 's apex after blunt trauma. The urethra should not be catheterized. Initial management should be the creation of a suprapubic cystostomy for urine drainage. The bladder should be opened in the midline so to facilitate inspection of bladder lacerations. Perforations can be closed with absorbable sutures. The suprapubic cystostomy remains in place for three months. Incomplete urethral disruptions heal spontaneously and the suprapubic cystostomy can be removed after three weeks for these injuries. Before removing a cystostomy, a voiding cystourethrography should demonstrate no urine extravasation. Delayed urethral reconstruction may be performed within 3 months. This typically entails a direct excision of the now strictured area and anastomosis of the bulbous urethra to the prostate's apex. A urethral catheter and suprapubic cystostomy should be left in place. These are removed within a month.
