[Metabolic complications of urinary intestinal diversion].
The use of bowel in urinary diversion has increased markedly over the last 15 years and this trend is expected to continue. Complications that have been noted in patients with urinary intestinal diversion occurring as a consequence of metabolic abnormalities include disordered electrolyte metabolism, osteomalacia, growth retardation, calculus formation, infection, abnormal drug metabolism. The factors that influence the intensity of absorption of urinary electrolites by intestinal mucosa include length of time of retention of the urine, concentration of solute in the urine, type of urinary diversion, quality of emptying, capacity of the reservoir, surface area of the bowel used, renal function, infection and chronic dilatation. Regular draining of the urinary intestinal diversion, vigilant metabolic follow-up, and careful patient selection are essential to prevent metabolic abnormalities.
