[Significance of the tuberculin test in the early detection of renal tuberculosis].

Authors used the tuberculin test (modified Koch's test) in 84 urological patients. In 22 of them, renal tuberculosis was revealed by this test and then confirmed by other methods. Subcutaneous injection of tuberculin in patients with renal tuberculosis was followed with the increase of leucocyturia and erythrocyturia. This reaction was especially expressive in the early stages of renal tuberculosis. The tuberculin test must be widely used in first-stage laboratory investigations in urological patients because it is easy and rapid.
