OBJECTIVES: To identify the risk factors associated with developing complications after transection of the urethral plate for proximal hypospadias with severe chordee. METHODS: We used a prospective database to identify patients with proximal hypospadias and severe chordee who underwent transection of the urethral plate and primary hypospadias repair in 2011 and 2021. All patients underwent urethroplasty with a follow-up period of >12 months. The association between variables (age, surgical technique, length of urethral defect, and surgeon volume) and postoperative complications (fistulas, urethral strictures, diverticula and glans dehiscence) was analyzed. RESULTS: Altogether, 493 patients were included, of whom 133 (26.9%) had postoperative complications. Univariate and multivariate analyses revealed that the preoperative proximal meatal position, one-stage repair, longer urethral defect length, and low surgeon volume were significant risk factors for postoperative complications with proximal hypospadias with severe chordee who underwent transection of the urethral plate. A urethral defect length of ≥4.55 cm was considered the best cutoff value for predicting postoperative complications. CONCLUSIONS: Preoperative proximal meatal location, one-stage repair, longer urethral defect length, and low surgeon volume were associated with postoperative complications in patients with proximal hypospadias with severe chordee who underwent transection of the urethral plate.
