Purpose

To evaluate whether a stent-plus-irrigation protocol reduces complication rates following hypospadias repair in adolescents compared with catheter drainage alone.

Methods

In this multicentre randomised controlled trial, adolescents (Tanner Stage II-V) undergoing hypospadias repair were randomly assigned to either a stent-plus-irrigation group or a catheter-drainage group.

n = 150 participants

Results

complications were about a third as likely with stent-plus-irrigation as with catheter drainage alone

Conclusion · 1 of 2

A postoperative stent-plus-irrigation protocol was associated with lower rates of postoperative complications, particularly urethral fistula and surgical site infection, compared with catheter drainage alone after adolescent hypospadias repair.

Conclusion · 2 of 2

Because the intervention included both an additional urethral stent and saline irrigation, the independent contribution of irrigation cannot be determined in this two-arm trial.
