External sphincterotomy in traumatic and non-traumatic neurogenic bladder dysfunction.

Experience with external sphincterotomy in 40 patients with traumatic and non-traumatic neurogenic bladder is reviewed. The procedure is a safe, reliable technique designed to establish a balanced neurogenic bladder in patients with detrusorsphincter dyssynergia. Spincterotomy should be performed in most patients before consideration of supravesical diversion.
