Utility of Preoperative Antimicrobial Prophylaxis in Hypospadias Repair: Results From National Surgical Quality Improvement Program Pediatric Registry.

PURPOSE: Literature supporting antimicrobial prophylaxis for hypospadias repairs is lacking, with largest studies including several hundred subjects. We sought to evaluate the association of a single dose of preoperative antibiotics in hypospadias repairs on postoperative outcomes using the National Surgical Quality Improvement Program Pediatric Registry.

MATERIALS AND

METHODS

The 2021 to 2022 National Surgical Quality Improvement Program Pediatric Registry was used to categorize hypospadias repairs into 3 groups-(1) 1-stage distal hypospadias repairs, (2) 1-stage proximal hypospadias repairs and second-/third-stage urethroplasties, and (3) repair of hypospadias complications. Patients with missing data regarding preoperative antibiotic prophylaxis administration were excluded. We evaluated the risk of wound complications (wound infection or dehiscence) and UTI. Binomial logistic regressions were performed with selected covariates including age, race, prematurity, relative value unit, operative time, American Society of Anesthesiologists score, and antibiotic prophylaxis.

RESULTS

There were 5026 patients in group 1, 1428 patients in group 2, and 1159 patients in group 3. A total of 6392 (84.0%) patients received preoperative antibiotics. Overall, the UTI and wound complication rates were approximately 3%. On multivariable analysis, preoperative antibiotics were associated with decreased wound complications in longer procedures (P = .018).

CONCLUSIONS

Preoperative antibiotics correlated with decreased wound complications in longer procedures. Owing to the overall very low incidence of postoperative complications, clinicians should consider omitting preoperative antibiotics in hypospadias repairs, particularly in lower-risk patients.
