Abstract
An anatomical study of the external sphincter of the urethra is presented. Around the membranous urethra the fibres are arranged circularly, giving off a constant anterior longitudinal prolongation into the prostatic urethra. It is postulated that the obliquity of the outer smooth muscle layer of the urethra is controlled by the anterior longitudinal component of the sphincter. An anterolateral sphincterotomy is suggested as the best method of external sphincterotomy.
