[The characteristics of cylindruria in patients with chronic glomerulonephritis]

Qualitative and quantitative indices of cylindruria were studied in 325 patients aged from 15 to 64 with various morphological forms of chronic glomerulonephritis (CGN). In 237 of them function of kidneys was unchanged while remaining 88 patients revealed various degrees of chronic renal failure (CRF). Parameters of cylindruria in patients with CGN varied widely, significant correlation having been established between presence of erythrocytic cylinders in urinary residue and degree of haematuria. Large granular cylinders were observed in patients with severe and moderate CRF as distinct from patients with normal renal function and initial stage of renal insufficiency.
