Reoperation after Hypospadias Repair: Long-Term Analysis

Area of Science:

• Pediatric Urology
• Surgical Outcomes Research

Background:

• The incidence of secondary hypospadias repair is not well-established.
• Existing literature suggests reoperation rates of 3.3%–6.7% for distal hypospadias repair.
• Previous studies indicate a potential association between age and reoperation rates.

Purpose of the Study:

• To investigate patient factors associated with secondary hypospadias surgery rates.
• To determine if current secondary surgery rates are underreported due to limited follow-up periods.

Main Methods:

• Analysis of a database from an academic practice plan consortium.
• Inclusion of patients who underwent primary hypospadias repair in 2009-2010.
• Tracking of secondary surgeries from 2009 to 2019.
• Statistical analysis using mixed effects multiple logistic regression models to assess variable associations.

Main Results:

• A cohort of 5,178 boys undergoing primary hypospadias repair was identified.
• Secondary surgery rates at 9-10 years were 12.6% (distal), 37.9% (proximal), and 46.6% (perineal).
• Patients with noncommercial insurance had a 26% increased odds of secondary surgery (OR 1.26, p=0.04).
• Patient age and surgeon experience were not linked to overall reoperation rates, except for endoscopic treatment.

Conclusions:

• Secondary surgery rates for hypospadias are likely underreported when follow-up is less than six years.
• Insurance status is a significant predictor of reoperation for hypospadias repair.
• Patient age, surgeon volume, and experience did not correlate with overall reoperation rates.
