Dietary Restriction of Sodium as a Means of Reducing Urinary Cystine

J Urol. 1990 Jun;143(6):1193-5. doi: 10.1016/s0022-5347(17)40222-9.

Abstract

We assessed 5 patients with recurrent cystine urolithiasis before and after implementation of a low sodium diet. This diet led to a significant decrease in the 24-hour urinary excretion of sodium and cystine. Dietary restriction of sodium should be an important component of the therapeutic strategy of patients with cystinuria.
