XYLOSE ABSORPTION AND METABOLIC STATUS IN URINARY INTESTINAL ORTHOTOPIC RESERVOIR - ILEOCECAL COMPARED WITH ILEAL NEOBLADDER

Purpose: We compare the absorption of D-xylose and vitamin B12, and th e metabolic status in ileocecal and ileal orthotopic neobladders. Mate rials and Methods: D-xylose plasma levels after an oral load, body com position, plasma vitamin B12, acid base and electrolyte balance were s tudied in 33 patients with an ileocecal reservoir and 13 patients with an ileal reservoir. Mean followup was 55 months. Results of both type s of operation and a healthy control group were compared. Results: Pla smic levels of D-xylose and vitamin B12 were significantly lower in th e ileal reservoir than in ileocecal reservoir group and normal control s. Conclusions: Despite an acceptable body composition, intestinal mal absorption could be present in patients with an ileal reservoir but th e ileocecal tract appears to be safe.
