Detection of latent bacteriuria in patients with chronic pyelonephritis.
Diagnostic possibilities of selective examination of renal urine particularly collected under medicamentous polyuria conditioned by the administration of Lazix were studied in latent bacteriuria. By means of separate collection of renal urine against the background of polyuria it was possible additionally to detect bacteriuria in 1/3 of the patients, to record increase in the intensity of the index in almost half of the patients with renal bacteriuria and, in 1/4 of them to detect, in renal urine, the aetiological agent absent from bladder urine. The latter circumstance not only has a diagnostic significance but also plays a certain role in the selection of medicamentous therapy in chronic pyelonephritis. In addition to traditional bacteriological methods, filtration through membrane filters was used to isolate and identify microflora in the urine. By means of this method it is possible to detect extremely low bacteriuria which cannot be established by any other method.
