METABOLIC AND NUTRITIONAL COMPLICATIONS - 11/09/11
Résumé |
Diversion of urine through an intestinal segment was first performed in 1851 by Simon.33 Since then, the use of gastrointestinal segments for construction of a urinary conduit or reservoir has become a widely practiced technique in reconstructive urology. In contrast to urothelial mucosa, which is relatively impermeable, the specialized absorptive and secretory properties of gastrointestinal mucosa make it a less than ideal substitute. When intestinal mucosa is interposed in the urinary tract, the resulting physiologic exchange of water and solutes between urine and blood contributes to a number of metabolic complications. These have been described and reviewed within the urologic literature.23 , 25 , 26 In addition, the loss of certain segments from the gastrointestinal tract may contribute to nutritional, gastrointestinal, and other metabolic complications. This article reviews basic intestinal transport, metabolic and nutritional complications relevant to particular gastrointestinal segments, and clinical relevance and treatment.
