Double-diaper technique with an open-drainage catheter is a common practice after hypospadias repair. However, double-diapering may increase the burden of postoperative care and has not been compared to single-diapering with an open-drainage catheter.
This study investigates whether the single-diaper technique is associated with inferior surgical outcomes compared to the double-diaper technique.
A single surgeon database was retrospectively reviewed for patients who underwent hypospadias repair between 2013 and 2021. Patients who were lost to follow-up and those in whom the type of diaper care (single- or double-diaper) was not documented were excluded. Patients in the single-diaper technique received the same type of dressing and discharge instructions, as those in the double-diaper group, except for leaving the catheter freely draining into a single-diaper. Short-term complications including surgical site infection (SSI), urinary tract infection (UTI) and wound dehiscence, were the primary outcome; whereas the long-term urethroplasty complications (urethrocutaneous fistula and meatal stenosis) were secondary outcomes. Outcomes were analyzed according to the type of diaper care.
Among 323 patients reviewed, 219 patients met the inclusion criteria (72 patients in the double-diaper and 147 in the single-diaper group). Both study groups were similar regarding patient demographics, hypospadias characteristics and surgical technique. Looking at the primary outcomes, there was no statistically significant difference in SSI, UTI or wound dehiscence. For the secondary outcomes, the incidence of meatal stenosis (8.3 vs. 1.4%, p = 0.044), and fistula formation (15.3% vs 5.4%, p = 0.037) was significantly higher in the double-diaper than the single-diaper group, respectively (Table 2).
Single-diaper technique following hypospadias repair is not associated with increased risk of complications compared to double-diaper technique.
