Summary The differentiation between glomerular and non-glomerular haematuria by phase-contrast microscopy has proved to be a useful tool in the diagnosis of glomerulonephritis. In an attempt to evaluate the effect of marked diuresis on the altered red cell morphology in patients with biopsy proven glomerulonephritis, urinary sediments were examined following water or furosemide-induced diuresis. In both diuretic states urine flow increased, urine osmolality decreased and the percentage of glomerular erythrocytes was significantly reduced in the urinary sediment. These data demonstrate that the alteration in urinary red cells in glomerulonephritis is mainly caused by tubular forces. The diagnostic significance is reduced during increased diuresis and the evaluation of urinary red cell morphology should not be performed.
