[Value of phase-contrast microscopy in the etiological diagnosis of hematuria in adults. Part II: Analysis of factors modifying morphology of erythrocytes in urine sediment].

In 41 patients with glomerular hematuria diagnosed by renal biopsy no correlation between intensity of tubulo-interstitial changes and range of dysmorphic erythrocytes (E) in phase-contrast microscopy (PCM) was found. However, such correlation existed in the case when acanthocytes in PCM were detected. From factors of potential influence on the morphology of E such as value of proteinuria, glomerular filtration rate, crystalluria, osmolarity and pH of urine, none had any significant role in changing the morphology of E of glomerular as well as of non-glomerular origin.
