Newly modified 'pseudo flap' without compromising vascularity to enhance repair of long distal ureteral loss: A retrospective analysis of a prospective database.

Our pseudo-flap technique has lower complication rates than the traditional Boari flap. It is not technically challenging, minimally compromises blood supply and is thus especially suitable for complex, highly morbid patients with decreased tissue vascularity, such as those with prior radiation and peritoneal carcinomatosis.
