[Metabolic studies during urinary diversion by way of the small intestine].

Examinations of the metabolism were carried out in 23 patients with ileal conduit and undisturbed renal function, in order to recognize the causes of stone-formation. In the infection calculi they are given with the alkaline urine, when an infection and a urinary retention is present. Perhaps the Ca-oxalate calculi develop within the hyperoxaluris in connection with a reduced citrate urine concentration. Differences in the composition of the conduit and renal pelvis urines could be proved.
