[Long-term clinical experiences with the cation exchanger UJOLYT as a metaphylactic in absorptive hypercalciuria and chronic recurring calcium oxalate lithiasis].

The UJOLYT cation exchange was checked in a clinically controlled study over a long period using 6 male test persons with chronically recidive calcium oxalate lithiasis and absorptive hypercalciuria. The PAK calcium load test proved clinically valuable in the differentiation of idiopathic hypercalciuria. The paraclinical findings revealed an average reduction of urinary calcium excretion by 40% and an increase of urinary magnesium excretion by 11.7% compared to the initial situation. The recidive frequency was clearly reduced. No serious side-effects were observed in the patients presented.
