Uromucoid excretion of normal individuals and stone formers

Uromucoid excretion was measured in 49 normal subjects and 79 patients with stones. The results showed no significant differences in the uromucoid excretion rate between these 2 groups; there was no simple quantitative relationship between uromucoid excretion rate and the genesis of stones. It is suggested that uromucoid may be concerned in a protective function of tubular epithelium and also in the transport of electrolytes and hydrogen ions.
