Wall dissection of the neourethra: a rare complication after hypospadias repair.

We present a rare complication causing severe infravesical obstruction after hypospadias repair after an initially successful double-faced island flap repair. The obstruction was caused by partial dissection of the epithelium of the urethral wall, comparable to intima dissection in an aortic aneurysm. To our knowledge, this type of urethral obstruction after a hypospadias repair has not been reported before.
