New urethroplasty for treating anterior urethral stenosis

Abstract

– Urethroplasties with free or pedicle preputial flaps are widely used in strictures of the spongy urethra. These techniques involve application of the preputial flap on the ventral surface of the urethra, with collapse of the spongy body and the frequent development of pseudodiverticula or urethroceles which are responsible for post-micturitional dribbling. The authors suggest a new urethroplasty for treating anterior urethral strictures, in which the free flap is applied dorsally and not ventrally, mechanically supported by the overlying spongy body and the underlying corpora cavernosa, and thus avoiding collapse of the flap. Thirty male patients with stenosis of the penile or bulbar urethra were treated with 2 different techniques using a free dorsal flap. Long-term results, with a mean follow-up of 34.5 months, were satisfying.
