%X OBJECTIVES:The contribution of cytological methods to the diagnosis and follow-up of urinary system malignancies was investigated in this study, along with histological diagnosis and clinical follow-up results of the cases. METHODS: One hundred forty-four cases who underwent cystoscopy in ZK¨¹TF Urology Department between 2003 and 2007 were included in this study, and urinary cytology and biopsy samples were assessed in the Pathology Department. RESULTS: When cytological and histological diagnoses were compared, results in 17 positive cases and in 109 negative cases were consistent. Three cases were false-positive and 15 cases were false-negative. In our series, sensitivity of urinary cytological diagnostic methods was 53% and specificity was 97%. CONCLUSION: Our study shows that urinary cytology has a high diagnostic value in the evaluation of urinary system diseases. However, decrease in the sensitivity of this method in low-grade urothelial tumors should be taken into account.
