[New data on the etiological factors in acute pyelonephritis].

Spectrum of microbe agents of acute pyelonephritis has been studied. It is shown that Mycoplasma hominis plays an important role in etiology of acute pyelonephritis besides the already known enterobacteria and Gram-positive cocci. It is also established that mycoplasmal pyelonephritis more often develops in patients with the diseases of urinary blade (cystitis) and genital organs.
