BACKGROUND: Hypospadias is one of the most common congenital malformations in men. The transverse preputial island urethroplasty is widely used in China, especially for moderate and severe cases due to its convenient prepuce of the penis. This analysis aims to delineate the time to first complication following transverse preputial island urethroplasty.
METHODS: We analyzed the clinical data and follow-up results of children who underwent hypospadias repair by transverse preputial island urethroplasty in Beijing Children's Hospital, Capital Medical University from December 2018 to December 2019 retrospectively. Postoperative complications included urethral fistula, urethral diverticulum, urethral stricture, persistent chordee. Univariate analysis of clinical variables and time to complication was performed using Kaplan-Meier survival curve.
RESULTS: One hundred and sixty-five patients were identified. During the follow-up period, complications occurred in 101 cases (61.2%). Ninety-four percent of complications occurred within 1 year. Among children who experienced complications, Kaplan-Meier survival analysis showed that age less than 18 months and the severity of hypospadias were statistically significant (P=0.005 and P=0.04, respectively). The time to urethral diverticulum was significantly longer than that of urethral fistula and urethral stricture.
CONCLUSIONS: More than 90% of complications after the transverse preputial island urethroplasty of hypospadias occurred within 1 year, with those related to proximal hypospadias presenting earlier than those of midshaft/distal hypospadias. Surgeons may consider a more frequent follow-up within the first year after surgery to detect these complications as early as possible.
