The effect of anteromedian sphincterotomy on penile erections in patients with neuropathic bladder

In a series of 94 patients with neuropathic bladder undergoing anteromedian urethral sphincterotomy, 20 had no penile erections prior to surgery. In the remaining 74 cases, seven (9 X 5 per cent) had diminished erections postoperatively and three (4 per cent) no erections. It is considered that the risk of this complication is less with anteromedian sphincterotomy than with bilateral 3 and 9 o'clock sphincterotomy.
