Efficacy of Body Wash and Povidone-Iodine in Skin Preparation in Reducing Surgical Site Infections After Hypospadias Repair Among Adolescents: A Prospective Cohort Study With Retrospective Controls.

Background

Surgical site infections (SSIs) that occur after hypospadias repair frequently result in incision healing complications, especially during puberty. This study aimed to evaluate the efficacy of twice-daily pre-operative skin preparation using body wash and povidone-iodine within 48 hours before hypospadias repair with regard to infection rates in adolescents. Patients and

Methods

Prospective recruitment included patients in Tanner stages 3 to 5 undergoing hypospadias repair from January 2015 to January 2021. The experimental group comprised patients who performed twice-daily skin preparation with body wash and povidone-iodine within 48 hours before surgery. Surgeons selected either 0.5% or 5% povidone-iodine for skin preparation. The control group comprised a retrospective cohort of hypospadias repair conducted in the preceding five years, where patients performed pre-surgery evening showers using a body wash. Complications were collected over a six-month follow-up period.

Results

The study included 90 patients in the 0.5% povidone-iodine group, 92 patients in the 5% povidone-iodine group, and 84 patients in the control group. Differences were observed among the groups in terms of SSI (p = 0.030) and urethral fistula (p = 0.019). In post hoc tests, only the 5% povidone-iodine group demonstrated a diminished incidence of SSI (p = 0.009) and urethral fistula (p = 0.005) in comparison to the control group.

Conclusions

Using body wash and 5% povidone-iodine for skin preparation was associated with a reduction in the incidence of SSI and urethral fistula following hypospadias repair in adolescents and may be considered to improve outcomes.
