Purpose: Data are lacking on prophylactic oral antibiotic use in stented hypo-
spadias repair cases. We evaluated the role of prophylactic oral antibiotics for
preventing symptomatic urinary tract infections in this population.
Materials and Methods: We reviewed consecutive patients treated with stented
primary/redo hypospadias repair by a single surgeon from September 2009 to
January 2012. All patients received antibiotics upon induction. Before April 1,
2011, patients also received prophylactic oral antibiotics while stented. They
were compared to those who underwent surgery after April 1, who received no
prophylactic oral antibiotics. The primary outcome was symptomatic urinary
tract infections, as captured from patient records and verified by an electronic
cross-check of ICD-10 codes. Secondary outcomes included cellulitis, fistula,
dehiscence and meatal stenosis.
Results: Of the 161 patients reviewed 11 were unstented and 1 underwent followup
elsewhere. Of the remaining 149 patients 78 received prophylactic oral antibiotics
and 71 did not. The groups were well matched for age, hypospadias characteristics,
surgical technique and stent duration. Median followup was 17 months (range 0.2
to 33). No culture proven, symptomatic urinary tract infections developed in either
group. One patient in the prophylactic group was treated for cellulitis by the
pediatrician. The complication rate, including redo cases, was 18.2% in the pro-
phylactic group and 15.3% in the nonprophylactic group (p ¼ 0.8).
Conclusions: When postoperative prophylactic oral antibiotics were not admin-
istered, we identified no increased incidence of symptomatic urinary tract in-
fections or complications. Our data suggest that prophylactic oral antibiotics may
not be needed in cases of stented hypospadias repair. This study contributes to
the growing body of evidence supporting the rational use of antimicrobials. It can
potentially serve as a basis for a prospective, multicenter, randomized study.

surgical reconstruction for this mal-

Previous studies advocate POA for
