Differential diagnosis and limitations of external sphincterotomy

A study of 1000 neurologic bladders has shown us that a well-balanced working of the bladder must be keenly searched for, and that sphincterotomy must be early indicated, and even performed several times if necessary. So 100 sphincterotomies performed on male patients, out of 730 cases, have shown us that their one-and-only risk, incontinence, depended chiefly of the condition of the detrusor, therefore on the short or long evolution of the sclerosis of the external sphincter, which is only one out of all the possible impediments.
