Long term outcomes from uncorrected hypospadias: a scoping review.

Introduction: The goal of hypospadias repair is to optimize urinary and sexual function, improve cosmesis and minimise the psychosocial effects associated with a penile anomaly. However, a lack of clarity exists regarding the role of surgery in milder hypospadias where the anomaly is inconspicuous and there is no anticipated impact on function. The aim of this study was to review the long term functional, cosmetic and psychosocial outcomes in men with uncorrected hypospadias. This information may be helpful for parents who are burdened with deciding the correct treatment for their child's hypospadias.

Methods: A scoping review of PubMed, EMBASE, and CINAHL + databases was performed in adherence with PRISMA guidelines. Eight studies were identified for inclusion in the review.

Results: Men with mild uncorrected hypospadias have similar functional outcomes to those without hypospadias, preferring to void standing and reporting similar IPSS scores. However, those with severe untreated hypospadias experience significant urinary difficulties, higher IPSS scores, and are more likely to sit when voiding. They reported worse SHIM scores, more ventral curvature, and greater difficulty with intercourse. Most men with incidentally identified hypospadias are unaware of their condition and are satisfied with their penile appearance. There was no difference in the attainment of psychosocial milestones between men with uncorrected hypospadias versus no hypospadias.

Conclusion: There is a lack of research regarding the experiences of adult men with uncorrected hypospadias. However, there is some evidence to support the non-operative management of mild hypospadias. Therefore, the decision to defer surgery in infancy should balance parental wishes and physician guidance, particularly in cases where the risk of functional impairment is low.
