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

Although more pediatric urologists prefer staged repair for proximal hypospadias with severe chordee right now, we still stick to one stage repair by transverse preputial island flap initially reported by Dr. Duckett. We believe this will benefit children and their families with less surgery and anaesthesia, less cost and shortened waiting time.

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

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.

Validation of the ureteral diameter ratio for predicting early spontaneous resolution of primary vesicoureteral reflux.

Management of primary vesicoureteral reflux (VUR) remains controversial, and reflux grade currently constitutes an important prognostic factor. Previous reports have demonstrated that distal ureteral diameter ratio (UDR) may be more predictive of outcome than vesicoureteral reflux (VUR) grade.
