title: External sphincterotomy at the 12 o'clock position.
abstract: Transurethral resection of the external sphincter was done at the 12 o'clock position 61 times in 60 men. There was a 2.8 per cent incidence of postoperative impotence and a 75 per cent cure of vesicoureteral reflux but there was only a 65 per cent success rate of decreasing post-voiding residual urine after 6 months. The techniques and applications of the procedure are discussed.
