Tunica vaginalis free graft urethroplasty: 10 years experience

28615

Objective: To evaluate the long term patient outcomes over a 10 year period among 52 patients who had tunica vaginalis (TV) for substitution urethroplasty. Patients and methods: Between October 2005 and December 2015, a total of 52 patients had TV substitution urethroplasty. 25 cases had one stage free graft dorsal urethroplasty while 27 cases had augmented anastomoses urethroplasty. Successful criteria were: patient satisfaction, urine flow rate above 16 mL/s, patent urethrogram and no need for dilation or any instrumentation during the follow-up period. Results: Overall success rate was 80.8%. Five cases completely failed due to severe wound sepsis and TV urethroplasty redone successfully 6–12 months later. Recurrent urethral stricture occurred in 5 cases over a period of 3–18 months. Superficial surgical site infection occurred in 7 cases. The 42 successful cases were voiding well, with an average flow rate 20 mL/s. None of the patients had any scrotal pain or discomfort in the follow-up period. Conclusion: To the best of our knowledge this is the first long term study using this technique with encour- aging results and the researchers propose that it is considered as an additional option by reconstructive genitourinary surgeons.
