Undiversion with ileocecal segment following high transureteroureterostomy

A boy presenting with a small bladder and refluxing blind-ending ureteral stumps following multiple attempts at ureteral reimplantation and supravesical diversion with a high left-to-right transureteroureterostomy and right cutaneous ureterostomy underwent successful undiversion. Surgery consisted of bilateral ureterectomy and ileocecocystoplasty, with intussusception of the ileocecal valve and anastomosis of the ileal tail to the right renal pelvis.
