  • Title: [Repair of hypospadias: the effect of urethral plate configuration on the outcome of Duplay-Snodgrass repair].

    Journal: Prog Urol; 2009 Jul; 19(7):507-10. PubMed ID: 19559383.
    Abstract:
    OBJECTIVES: A number of factors potentially influence the outcome of hypospadias surgery. We evaluate the effect of catheter-size used during urethroplasty (a detail related to the depth of the urethral groove and width/elasticity of the urethral plate) on the complication rate following Duplay-Snodgrass repair. METHODS: The data of 113 patients undergoing primary hypospadias repair was retrospectively reviewed. Patients were divided into two groups based on the urethral plate width evaluated by the catheter-size used during urethral reconstruction, and the rate of complications was compared in the two groups. Other factors evaluated included age of patients and severity of the defect. RESULTS: Complications (urethro-cutaneous fistula and meatal stenosis) were more common in the narrow urethral plate 8F catheter group (three fistulae among 18 patients) compared to the wide urethral plate 10F catheter group (six fistulae and one meatal stenosis in 95 patients) (p=0.08). CONCLUSION: The width of the urethral plate during a modified Duplay urethroplasty has a significant impact on outcome. A smaller-sized catheter for neo-urethral reconstruction, implying a shallow urethral groove and a narrow or inelastic urethral plate, is associated with a higher rate of urethrocutaneous fistula and meatal stenosis.
