Abstract

Introduction: Surgical correction of hypospadias aims to achieve normal functionality and appearance. This entails foreskin reconstruction (FR) in countries where the uncircumcised penis constitutes the norm. Long-term data are however scarce. Objective: To investigate the long-term outcome of FR in cohort of patients operated for distal hypospadias combined with approximately 20 years after surgery. Methods: The hospital management system was searched for patients operated for distal hypospadias in conjunction with FR between 1997 and 2004. Prospective participants were invited to participate in an online questionnaire. Signed consent allowed for extended medical chart review, with regards to hypospadias grade, surgical procedure and complications. Results: Response rate of 44.6 %. For 113 participants, median age at primary surgery was 5.2 (1.0–15.5) years. Two-thirds had a distal meatus while the remaining, meatus was mid to distal shaft. Urethroplasties performed were mainly glanular approximation procedures and meatal based flap procedures in 85 %. Foreskin fistula developed in 15 % of cases. There was no significant relationship between urethroplasty procedure or meatal position and risk of foreskin complications. Three layer closure of foreskin resulted in significantly less complications than two layer closure. Twenty years on 95 % of the men still had an intact foreskin, of whom 16.8 % had received treatment for phimosis. Foreskin was retractable in 92.5 % and 74.7 % in the flaccid and erect states respectively. Ninety intact men had had their sexual debut and in those 23.3 % reported foreskin related issues with intercourse. Evolution of foreskin retractability can be seen in the figure. Discussion: Current results show that three layer FR in conjunction with hypospadias surgery is feasible and that short-term complication rates were comparable with what has previously been published in the literature. Long-term results indicate that FR is durable with regards to anatomical reconstruction however foreskin function especially in relation to sexual function was compromised in about 25 %. Foreskin retractability after surgery predicted retractability in adulthood for the flaccid but not erect penis. Limitations of this study include the retrospective nature of data collection, and that the questionnaire used was not validated. We however achieved a decent response rate and were able to capture important long-term data. Conclusions: FR has an acceptable complication rate. Long-term results two decades on are remarkably durable with regards to the anatomical preservation of the prepuce, however functionality was compromised with regards to retractability and sexual function in approximately 25 %.[Formula
