[Metabolic aspects of intestinal urinary diversion. Comparison with ileo-cecal bladder substitution and ileal conduct].

: The aim of this study was the metabolic evaluation of 10 patients with 2 different types of urinary diversions, after cystectomy for infiltrating carcinoma. The patients were divided into two groups, homogeneous for age and follow up, according to the type of urinary diversion: group A (5 patients with ileo-cecal bladder) and group B (5 patients with ileal conduit). The follow up duration was 16.8 +/- 7.3 months in group A and 25.4 +/- 7.8 months, in group B. Even though the glomerular filtration rate (GFR) in both groups was within the normal limits, however - on closer evaluation - patients of A group revealed a slight functional damage, shown by reduced creatinine secretion, lower bicarbonatemia and lower urinary acid secretion when compared with ileal conduit patients. According to this study, the ileal conduit seems to be associated with a fairly good metabolic status while the ileo-cecal bladder could require closer clinical-metabolic follow up and bicarbonate supplementation.
