Urinary changes were investigated in 20 patients with J-pouch ileo-anal anastomoses and 8 patients with ileostomies. Urinary output, sodium and pH were significantly lower than in health controls. Three grams of a citrate mixture (104 mg of Na/gm and 178 gm of K/g) were given to these patients. Urinary sodium and pH were elevated, and incidentally, the urinary uric acid level was reduced and the mixture was thought to be effective for prevention of uric acid stone formation.
