[Urinary calculus protective side effects of anti-rheumatic therapy].

In a retrospective study two patient groups suffering from recurrent calcium oxalate lithiasis are compared before and after antirheumatic therapy using Diclofenac-Natrium alone or in combination with xanthine oxidase inhibitors and/or hydrochlorothiazides. The examination of concentration and excretion of lithogenic important parameters show a partly significant reduction of the concentration mean values of calcium, oxalic acid and uric acid. The influence of non-steroidal antiphlogistics (NSAP) on calculus recurrence rate in calcium oxalate lithiasis is recognized.
