OBJECTIVE: To compare the operative outcomes of the modified and conventional Duckett procedures for severe hypospadias, and to evaluate the clinical value of the modified Duckett (M-Duckett) procedure.
METHODS: We conducted a comparative study of 132 paediatric patients with severe hypospadias who had a minimum follow-up of 24 months and underwent different surgical procedures at the Department of Paediatric Surgery, The First Affiliated Hospital of Zhengzhou University, between January 2018 and February 2023. Based on the surgical technique, 75 patients constituted the M-Duckett group, while the remaining 57 comprised the Duckett group. The M-Duckett procedure incorporates refinements to the conventional technique, primarily pertaining to the anastomosis between the native urethral meatus and the neourethra, as well as the architectural reconstruction of the external urethral meatus. Preoperative baseline data, perioperative parameters, and postoperative outcomes were compared between the two groups.
RESULTS: No significant differences were observed in preoperative baseline data and perioperative parameters between the two groups. However, the incidence of postoperative urethral stricture was significantly lower in the M-Duckett group (9.3%) than in the Duckett group (22.8%; χ2 = 4.573, P = 0.032). Furthermore, a bell-shaped urinary flow curve was observed in a significantly higher proportion of patients in the M-Duckett group (69.4%) compared to the Duckett group (45.8%; P = 0.048). No other postoperative outcomes showed significant intergroup differences.
CONCLUSION: In comparison to the Duckett procedure, the M-Duckett procedure is associated with a lower rate of postoperative urethral stricture and a higher proportion of bell-shaped uroflow curves, without increasing the risk of other postoperative complications or leading to an undesirable penile appearance.
