[Stress and risk of urolith formation. I. The influence of stress on lithogenous urinary substances (author's transl)].
In the present work the influence of stress situations on the concentrations and excretions of lithogenous urinary substances (calcium, oxalic acid, uric acid) has been studied in defined urine portions of 10 calcium oxalate stone patients and 10 normal subjects and the results compared to those of 20 stone patients and 10 normal subjects without stress. Stress may be objectified in the given task. The increase of concentrations and excretions of lithogenous urinary substances indicates an enhanced risk of stone formation. Uric acid is discussed as an agent promoting the calcium oxalate crystallization. New insights on the calcium oxalate stone genesis are gained from the results.
