[Bacteriologic study of the urine of pyelonephritis patients following administration of saluretics].

The qualitative and quantitative bacteriological study of renal urine samples selectively taken from pyelonephritis patients before and after the administration of lasix was made. This study revealed that simultaneously with plyuria the increased frequency of colony growth occurring after inoculations from urine samples and the greater degree of bacteriuria were observed. The qualitative analysis of microflora in the selectively taken samples of renal urine revealed the presence of additional etiological agents which were absent in the samples of bladder urine. These findings indicate that the bacteriological study of renal urine samples simultaneously with the administration of lasix allows to obtain additional information useful for the diagnostics of pyelonephritis and for the choice of rational schemes of antibacterial therapy.
