title: Acid-base and electrolyte balance in urinary intestinal orthotopic reservoir: ileocecal neobladder compared with ileal neobladder.
abstract: OBJECTIVE
  To compare acid-base and electrolyte balance in ileocecal and ileal neobladders.
  
  
  METHODS
  Acid-base and electrolyte balance were studied in 45 patients with an ileocecourethrostomy and 18 patients with an ileal reservoir. The mean follow-up was 51 months. Results were compared with regard to both the type of operation and the time since surgery.
  
  
  RESULTS
  No significant differences were found with regard to either the type of operation or the length of follow-up. A preserved renal function is important in maintaining a healthy status.
  
  
  CONCLUSIONS
  The use of 35 to 40 cm of ileum or 10 cm of cecum with the ileocecal junction seems to be safe even after a long follow-up. The length rather than the kind of bowel used for bladder replacement appears to be important in safeguarding hydroelectrolyte and acid-base homeostasis. This is particularly true in the presence of preserved renal function.
