Haematuria; Phase Contrast Microscopic Examination OF 100 Cases For Localization Of Source Of Bleeding.
Professional Med J Jan ;24(10):1589-92.

Introduction: Urine analysis was the first laboratory test performed in medicine and has been used for several thousand years. Today it continues to be a powerful tool in obtaining crucial information for diagnostic purposes in medicine.1 Aims and Objectives: To estimate the source of bleeding by erythrocyte morphology on PCM, in patients with haematuria. Study Design: Descriptive. Setting: The Nephrology and Urology out Patients. Period: 2014 to 2015. Methods: Urinary samples were collected from 100 random patients who presented with haematuria. Samples were examined by face contrast microscope.Urine RBCs were identified as isomorphic and dysmorphic, proportion was taken, >20% of either cells were used for localizing the source of bleeding. Later on, finding was furtherconfirmed by ultra sound or other investigations like renal Biopsies and cell cytology. Result: In our study we found that not only the correct bleeding site can be located with a high specificity, but also additional findings can be looked for with a little background knowledge of patient’s medical history. Conclusion: Phase contrast microscopy should be used by the clinicians for gathering the primitive information in the patients with haematuria.
