UROLITHIASIS IN PATIENTS WITH A JEJUNOILEAL BYPASS

Abstract

Patients [517] who had a jejunoileal bypass were studied with regard to the formation of urinary calculi postoperatively. A 9% incidence of stones was found in the 365 patients for whom complete data were available. Men were affected more commonly than women. The correlation between long term oral supplementation of calcium postoperatively and a delay in the onset of symptomatic urolithiasis is significant. Ninety-one patients maintained on orally administered Ca are stone-free as long as 12 mo. after operation. Supplementation of Ca may help prevent urolithiasis in patients who have had a bypass procedure.
