title: [Acute primary pyelonephritis or active phase of a latent form of chronic pyelonephritis?].
abstract: Analyzing the data of a comprehensive examination of 372 patients admitted to hospital with a distinct clinical picture of acute pyelonephritis, the author shows that out of these patients' population, 278 (74.8%) had an active form of chronic disease running a latent course. At the same time 40.4% of cases were diagnosed to have chronic renal failure (CRF), stages IB-IIB. To determine the genuine character of renal injury, the author thinks it necessary to regard the symptom-complex of acute pyelonephritis as a consequence of the pyelonephritic process itself. In complicated cases of the diagnosis, biopsy of the kidney concerned is required. In 176 patients the final diagnosis was established by uroradiological examination, in 59 by means of the use of laboratory methods, and in 137 by biopsy of the involved kidney. It is recommended that patients with renal pathology should be kept under prolonged dispensary observation, particularly those with an initial stage of CRF.
