Abstract :

Background: Urine cytology is primarily used for diagnosis of symptomatic patients, detection of cancer in high–risk patients and follow–up of patients with history of urinary tract neoplasia. Aims &Objective: To find out the efficacy of urine cytology smear in detecting malignant lesions of the bladder in patients coming with bladder symptoms. Materials and Methods: Voided urine samples were obtained from 160 symptomatic patients, urine cytology smears were made and analyzed. Out of 160 cases, bladder biopsy specimens were obtained for 84 cases and cytohistological correlative study was done. Results: Cytohistological correlation revealed the overall sensitivity as 74.1%, specificity as 96.7%. accuracy as 82.1%, positive predictive value as 97.6%, negative predictive value as 67.4%. Conclusion: Cytological examination of urine is more sensitive in detecting high grade urothelial carcinoma.
