[L-forms of bacteria in the urine of patients with chronic pyelonephritis].
The authors present the data concerning the study of 200 patients suffering from chronic pyelonephritis; in 28 of these L-forms of bacteria were revealed in the urine. Of 46 L-cultures isolated from these patients 13 reversed into bacterial forms, 8 failed to reverse and were referred to the stable L-forms; the rest 25 L-cultures perished during the 8th--10th passage. This led to a supposition that the relapses and exacerbations of the infectious process in pyelonephritis were associated with the change of the L-forms into bacterial ones, and that the persistence of the L-forms in the kidney tissue promoted the maintenance of the chronic process.
