Short- and mid-term outcome of different types of one-stage hypospadias corrections.

Abstract

This study is a retrospective analysis of the outcome of our one-stage hypospadias corrections. In the period from August 1979 to January 1991, 316 boys less than 14 years of age underwent a one-stage hypospadias correction in our hospital. For 283 patients, data on the familial incidence, associated urological pathology, age at the time of operation, operation technique and follow-up were analyzed. The familial incidence in our study group was 9.4%, associated cryptorchidism was seen in 8.6%, kidney abnormalities in 1.8% and urethral valves in 0.4%. The majority (65.3%) of the children were operated on before the age of 3 years. The operation was performed according to Magpi, Mathieu, Devine-Horton, an onlay, and tube formation according to Duckett and the double-faced island flap procedure. Including all postoperative disturbances, urethral complications were seen in 18.1% and skin-related complications in 4.6% of the patients. Even in experienced hands the overall complications rate is relatively high, and additional problems can be expected in the future. It is important to provide adequate information on the procedures and possible complication to the parents. The final long-term outcome after puberty has to be awaited.
