Acquired megalourethra: an uncommon complication of the transverse preputial island flap urethroplasty.

We describe 4 patients with significant dilatation of the entire neourethra following transverse preputial island flap urethroplasty. Two patients presented after repair of chordee without hypospadias, which was corrected by interposition with a pedicle graft. The problem arises about 6 months after the repair and is manifested by ballooning of the urethra during urination and postvoid dribbling. We have labeled this entity acquired megalourethra and the repair is similar to that for congenital megalourethra.
