PURPOSE: The aim of the study was to report a new technique for repairing hypospadias with severe chordee (HSC). METHODS: Our new technique involves making a long, wide, U-shaped incision on the ventral penis from the coronal sulcus to very distal to the meatus and dissecting to create a flap (U-flap). During dissection, the urethra is divided just proximal to the meatus. After release of chordee, the U-flap is returned to the ventral penile shaft and sutured in place. A buttonhole made distally in the U-flap is anastomosed to the cut end of the urethra to create a neomeatus. Snodgrass urethroplasty is performed 6 to 18 months later. We have treated 11 patients with HSC (mean age, 22.3 months) using this technique. RESULTS: Postoperatively, all U-flaps were viable. The neomeatus appeared to be more proximal because the penis was straighter. Urethroplasty using the central part of the U-flap was uncomplicated by scar tissue and successful in all cases. After a mean follow-up of 15.7 months, all patients have satisfactory penises without stenosis or diverticulum, although 1 had fistula. CONCLUSION: Our U-flap technique allows the ventral penis to be preserved intact without scarring for second-stage urethroplasty and as a result is well suited for treating HSC.
