For histological examination of the affected pathological process, as a rule, both kidneys from their cortical and cerebral zone, cut out pieces that were fixed in a 10 % solution of neutral formalin, poured into paraffin, sections 5–6 microns thick were prepared on a sled microtome, then stained with hematoxilin and eosin according to conventional methods. The sections were examined and photographed under a Leica microscope. The complex of in vivo clinical and postmortem pathoanatomical and additional histological studies was directed to confirm the diagnosis „chronic renal failure“.
