Preliminary Application of a Novel Anatomic Urethroplasty Technique Using Everted Saphenous Vein Graft for Long Penile Urethral Strictures

Abstract

Background: This paper reports two cases of anatomic urethroplasty (AU) using everted saphenous vein graft (eSVG) with long penile urethral strictures. The preliminary feasibility and safety of the operation are also analyzed. Methods: Two men with penile urethral strictures (5.5 cm and 5.0 cm) were treated with AU using eSVG. The highlight of this novel surgical technique was the anatomical repair of the layer of the narrowed urethral wall without affecting the continuity of the layer of corpus spongiosum. Moreover, the pre- and postoperative Urodynamics and Night Penis Tumescence and Rigidity test results were compared. Results: Complications, such as hematoma, urinary fistula, or urethral strictures, were not observed at 2 weeks postoperatively. At 6 months postoperatively, the urination status and urodynamic indexes of the patients had significantly improved compared with that preoperatively. There was no significant change in erection function before and after the operation. Conclusions: Repairing long penile urethral strictures with AU using eSVG is safe and feasible and can be used as an alternative treatment method.
