One-stage repair of proximal hypospadias with severe chordee by in situ tubularization of the transverse preputial island flap

Abstract

To investigate a modified transverse preputial island flap repair which is performed in an attempt to reduce the complications following one-stage repair of proximal hypospadias with chordee. Briefly, the two ends of the flap were trimmed into V shape and anastomosed with the spatulated urethra proximally and urethral plate distally before tubularization. Then the in situ tubularization of the flap was performed. The procedure was performed in our hospital on 32 patients (mean age = 11 months). They were followed for 12-38 months. The length of the urethral defect ranged from 4.0-6.0 cm after chordee correction. Urethrocutaneous fistulae occurred in 6 (18.7%) cases. No urethral strictures or meatal stenoses were observed. 29/32 families were satisfied with the cosmetic results. This procedure seems straightforward and reliable, leading to good result after a short-term follow-up.
