Introduction The aim of this study was to evaluate whether prolonged stenting reduces the risk of urethral stricture after proximal hypospadias (PH) with severe curvature (SC) repair. Materials and Methods We prospectively studied a cohort of patients with PH with SC repair who underwent urethral plate transection and urethroplasty between January 2010 and December 2020. According to the duration of stenting, the patients were divided into 2-, 4-, and 6-week groups. Postoperative complications and time of urethral stricture occurrence were analyzed. Results In total, 665 patients were included in the analysis. The overall incidence of complications was 26.6% (n = 177), including 42 cases of urethral strictures: 27 (64.3%) cases of urethral stricture occurred between 4 and 6 weeks after urethroplasty, 7 cases occurred between 7 weeks and 6 months after urethroplasty, 7 cases occurred more than 6 months after urethroplasty, and 1 case occurred at 3 weeks after urethroplasty. The incidence of urethral stricture in the 6-week group (1.8%) was significantly lower than that in the 4- (5.8%) and 2-week groups (10.9%) (p

In brief

This prospective cohort study of 665 patients demonstrates that extending urethral stenting to 6 weeks after proximal hypospadias repair with severe curvature significantly reduces urethral stricture rates (1.8%) compared to 4-week (5.8%) and 2-week (10.9%) stenting protocols. Most strictures occurred between 4-6 weeks post-surgery, supporting prolonged stenting as a protective strategy.

Prolonging urethral stenting to 6 weeks significantly reduces stricture risk (1.8%) vs 4 weeks (5.8%) or 2 weeks (10.9%) after proximal hypospadias repair.
Most urethral strictures (64.3%) occur between 4-6 weeks post-urethroplasty, during the critical healing period after stent removal.
In proximal hypospadias with severe curvature requiring urethral plate transection, extended stenting duration improves surgical outcomes.
Overall complication rate was 26.6% in this cohort of 665 patients, with urethral stricture representing a minority of complications.
Optimal stenting duration appears to be 6 weeks to allow adequate urethral healing and minimize early stricture formation.
