Introduction: The aim of the study was to assess the clinical and functional results after continent cutaneous diversion with the ileal double-T-pouch. Patients and Methods: Between July 1998 and July 2006, 19 patients underwent continent urinary diversion with a cutaneous ileal double-T-pouch. Follow-up investigations included blood chemistry, renal ultrasound and evaluation of the outlet function. The median follow-up was 24 months (range 3–76). Results: There were no intraoperative complications and no perioperative mortality. Early postoperative complications not related to urinary diversion occurred in 6 patients (31.6%). Five patients developed complications related to the urinary diversion (26.3%). The mean operating time was 580 min (420–840). Including the patients who had good results after reoperation, 16 out of the 19 patients (84.2%) were continent day and night without any catheterization difficulties. The average pouch capacity was 490 ml (range 250–1,100). A mild acidosis was the only metabolic disorder observed. During follow-up renal function remained stable in all patients, urinary reflux, recurrent pyelonephritis or stone formation were not found. Three patients with a body mass index >30 developed a necrosis of the efferent loop resulting in pouch cutaneous fistulas. Conclusions: Continent cutaneous urinary diversion with the ileal double-T-pouch led to good intermediate functional and clinical results. However, construction of the pouch is sophisticated, resulting in a long operation time. The double-T-pouch is not recommended in obese patients.
