Herniotomy at the Primary Repair of Bladder Exstrophy Revisited

Area of Science:

• Pediatric Urology
• Surgical Outcomes
• Congenital Anomalies

Background:

• Male bladder exstrophy (BE) presents complex surgical challenges.
• Inguinal hernias are a common complication in BE patients.
• Management strategies for hernia in BE patients vary.

Purpose of the Study:

• To evaluate inguinal hernia incidence and recurrence in male BE patients undergoing bladder closure and Kelly repair.
• To compare outcomes with alternative surgical strategies like complete primary repair of exstrophy (CPRE).

Main Methods:

• Retrospective review of 154 male BE patients (1995-2023).
• Comparison between patients with prophylactic herniotomy (n=67) and those without (n=87) at bladder closure.
• Analysis of hernia emergence, recurrence, timing, and incarcerations.

Main Results:

• Prophylactic herniotomy group: 15.1% hernia recurrence (median 12.6 months).
• Non-prophylactic group: 34.5% hernia development (median 3.2 months).
• No incarcerations in the prophylactic group vs. 20% incidence in the non-prophylactic group.

Conclusions:

• Prophylactic herniotomy during infant bladder closure reduces hernia emergence and recurrence.
• Surgical timing and approach (staged vs. CPRE) influence hernia presentation and recurrence.
• Prophylactic herniotomy is a protective intervention in staged repair for male BE patients.
