Quantitative measures of proteinuria, hematuria, lipoiduria and cylindruria have been studied in 156 patients with chronic glomerulonephritis in the course of long-term survey. The parameters evaluated and their combinations were noted to vary considerably. Proteinuria and/or hematuria not infrequently associated with cylindruria and/or lipoiduria were common in mesangioproliferative, mesangiocapillary and membranous glomerulonephritis. Patients with focal-segmentary glomerulosclerosis-hyalinosis and minimal glomerulonephritis in the stage of remission revealed no pathological changes in urine. Statistically valid correlation was established between the degrees of proteinuria (as well as between those of lipoiduria) and proteinuria while there was no link between proteinuria and hematuria.
