Metabolic changes in patients undergoing right colon continent urinary pouch diversion.

The concept of continent urinary diversion is undergoing re-evaluation now that a stable continent valve can be produced with certainty. The right colon pouch consists of the distal 6 inches of the terminal ileum, the cecum, ascending colon, and proximal third of the transverse colon, and has a volume of up to 1,200 mL. The present study investigates the electrolyte changes that occur when urine is held in the pouch for increasing lengths of time. No significant changes in serum electrolytes occurred with catheterization intervals up to six hours in a group of patients that were studied for an excess of six months.
