Cytological method of research in the diagnosis of urinary pathology in liver cirrhosis

Objective. To determine the possibilities of cytological method of urine cellular sediment examination for diagnosis and differential diagnosis of renal and urinary tract pathology in liver cirrhosis.Materials and methods. A standard observational study of 50 inpatients with liver cirrhosis was performed. Cytological preparations of urine sediment were prepared by liquid cytology and cytocentrifugation methods and after fixation were Results. Cytological study of cellular urine sediment in hospitalized patients with cirrhosis revealed dysmorphic (leached) erythrocytes in 31% of cases, statistically significantly more frequently in patients with decompensation of the disease and 30-day mortality (p<0,05). Microflora in the urine was found in 63% of patients, more often of mixed nature (27%). In 46% of patients with decompensated liver cirrhosis, including acute renal injury, cytological preparation of urinary sediment is represented by multicellular elements with the presence of superficial and deep urothelium and renal epithelium.Conclusions. Cytological method of studying the cellular urine sediment is an accessible, informative and cheap diagnostic method, the possibilities of which are to determine the presence and origin of cellular elements (urothelium of the surface and deep layers, altered erythrocytes), microflora and its source (genital tract, urinary tract), which, in combination with other methods, allows to verify the diagnosis of the patient and to carry out differential diagnosis of acute tubular necrosis and hepatorenal syndrome.
