Abstract:
OBJECTIVE: To explore the surgical outcome of Duckett urethroplasty-urethrotomy for staged hypospadias repair. METHODS: Fifty-three patients with hypospadias were treated by 2 stages between August 2013 and September 2014. The age ranged from 10 months to 24 years and 3 months (median, 1 year and 10 months). There were 5 cases of proximal penile type, 2 cases of penoscrotal type, 36 cases of scrotal type, and 10 cases of perineal type. Urethroplasty was performed with tubed transverse preputial island flap only in 27 cases or combined with urethral plate in the other 26 cases, thus a urethrocutaneous fistula was intentionally created; stage II fistula repair was carried out at 1 year after stage I repair. RESULTS: The length of the new urethra ranged from 2 to 8 cm with an average of 3.6 cm. The patients were followed up 5-17 months with an average of 8 months after stage II repair. After stage I repair, urethral fistula was noted at other site in 3 cases, skin necrosis in 1 case, glandular stricture in 2 cases, cicatric curvature in 1 case, and position and morphology of urethral orifice not ideal in 4 cases. After stage II repair, urethral fistula was noted in 2 cases, mild urethral diverticulum in 2 cases, and stricture at temporary repair site in 1 case. HOSE score was 12-16 at 3 months after stage II repair (mean, 14.5). At 3-14 months after stage II repair, the maximum flow rate ranged from 3.9 to 22.7 mL/s with an average of 8.6 mL/s. CONCLUSIONS: Duckett urethroplasty-urethrotomy can be used as staged repair for primary treatment of hypospadias because of high safety, low complication incidence, and satisfactory appearance.
