The Need for Additional Procedures in Patients Undergoing Proximal Hypospadias Repairs as Reported in the Pediatric Health Information System Database

Abstract

Using administrative data from freestanding pediatric hospitals in the United States, we characterized the frequency and type of additional procedures required in patients undergoing proximal hypospadias repair in a larger cohort than in published case series across multiple surgeons and institutions. A search of the Pediatric Health Information System (PHIS) database by CPT code between January 1, 2005 and June 30, 2010 identified patients undergoing 1 or 2-stage repair for proximal hypospadias. Patient records with inconsistent coding or the suggestion of an alternate pathological condition were excluded from study. A forward query to June 30, 2011 identified additional hypospadias related interventions by CPT codes. We identified 1,679 patients from a total of 37 hospitals. Potential followup was 1 to 6.5 years. One-stage repair was performed in 85.7% of patients at a median age of 10 months. In patients undergoing 2-stage repair the median age at initial repair was 10 months and the median interval between stages was 6 months. Of all patients 26.2% required 1 or more additional interventions beyond definitive repair. Of all additional interventions 84.0% were open, 7.2% were endoscopic treatment for stricture, 0.4% were combined endoscopic and open interventions, and 8.4% were endoscopic evaluation. The median interval from definitive repair to the first intervention was 9 months. These data indicate that more than a quarter of patients who underwent proximal hypospadias repair at pediatric hospitals required additional intervention(s) after what was thought to be definitive repair. These data help create a broader context in a contemporary cohort of patients treated with proximal hypospadias repair.
