[Significance of the studies of urinary syndrome in clinical practice].

The study of urinary sediment is essential in laboratory diagnosis. Conventional clinical methods are now used in line with computer-aided techniques and additional microscopy of the sediment elements. The paper provides a brief analysis of clinical situations characterized by appearance in the urine of abnormal numbers of leukocytes, erythrocytes, casts; provides clinical assessment of additional microscopic methods able to accentuate qualitative characteristics of the urinary syndrome; considers possibilities of application of the urinary sediment data in follow-up to improve diagnosis and control on-going treatment.
