Pak J Surg Jan ;34(3):192-5.

Introduction: Hypospadias is a common congenital anomaly of the urogenital system, with an incidence of 1:300, in males. Hypospadias is defined as an anomaly involving the ventral aspect of the penis. Urethro-cutaneous (UC) fistula complicating hypospadias repair appears the most common problem. The incidence of Urethro-cutaneous fistula varies from 4% to 28%. Objective: To determine the frequency of urethrocutaneous fistula in post Aivar Bracka repair meatal stenosis. Materials and Methods: This study was conducted at Department of Plastic and reconstructive Surgery unit, Hayatabad Medical Complex Peshawar, from march 2014 to march 2016. Study design was descriptive cross-sectional study and the duration of the study was 2 years in which 82 patients were observed by using WHO formula for sample size, expected prevalence of 22% of fistula, 95% confidence Interval and margin of error of 9%. Non-probability consecutive sampling technique was used for sample collection. Results: In our sample, 72% patients were in age range 3-6 years, 28% patients were in age range 7-10 years. Mean age was 3 years with SD±1.31. Overall 20% patients had urethrocutaneous fistula. Stratification of urethro-cutaneous fistula with age distribution was analyzed, showing that 12 patients with urethro-cutaneous fistula were in age range 3-6 years and 4 patients were in age range 7-10 years. The difference in fistula frequency between the two age groups was statistically significant (p < 0.01). Conclusion: Our study concludes that 20% of patients with meatal stenosis develop urethrocutaneous fistula after aivar bracka repair, and the frequency is higher in the younger age group.
