概要 | Background: We describe and clinically review a new non-transecting urethroplasty technique for treating penobulbar urethral strictures: Double-sided Heinecke-Mikulicz urethroplasty using a ventral approach. Patients and Methods: The study included 10 patients aged 22-83 years affected by urethral strictures 3-20 mm in length, resulting from transurethral procedures (n = 5), hypospadias repair (n = 3), and trauma (n = 2). The procedure was approached by transperineal penile invagination in seven cases and by penile incision in three cases. In four cases with longer strictures, the bulbar urethra was mobilized proximally to avoid anastomotic tension. A ventral midline urethral incision was made, encompassing the stricture, and the dorsal wall was also incised in midline. The dorsal incision was sutured longitudinally with 5-0 absorbable monofilament from the luminal side and the ventral incision was closed longitudinally with 4-0 sutures, completing the Heinecke-Mikulicz technique in the dorsal and ventral urethral walls. Results: The operation time was 92-166 min (median 127.5 min) and the postoperative observation period was 3-15 months (median 9 months). The maximum urinary flow rate improved from 0-18.6 ml/sec (median 7.2) preoperatively to 16.3-53.9 (median 21.9) postoperatively. No patient reported penile shortening. Conclusions: The present study reports a simple and useful non-transecting urethroplasty technique for treating short urethral strictures in penobulbar junction. |
