Outcome of urethro cutaneous fistula repair

ABSTRACT

To evaluate the outcome of urethro cutaneous fistula repair. This was a prospective study conducted in department of urology Jinnah Postgraduate Medical Centre [JPMC], Karachi. Seventeen cases with urethrocutaneous fistulas were enrolled in this study. In 12 [75%] we did the simple repair and second layer with dartos, in 03 [16.7%] OIU and silicone catheterization was done, but they recurred then repair with tunica vaginalis cover was performed and 02 [8.3%] patient underwent OIU plus simple repair with dartos. The mean age was 25.58 +/- 6.2 years, in 11 post hypospadiasis was the cause of urethrocutaneous fistula. Recurrence was observed in four patients. Two patients after post hypospadias repair; one after stricture peno-scrotal and one after post infection, boil at base of penis had recurrence. Two patients with simple repair and 2[nd] layer with dartos had recurrence, two patients treated with OIU had recurrence and after that repair with tunica vaginalis cover was performed with no recurrence and none of the patients treated with OIU plus simple repair with dartos had recurrence. Circumferential incision around the fistula opening, tension free closure with fine PDS suture is the key for successful treatment of urethral fistula
