Urinary cytology and its correlation with bladder carcinoma

The best method to confirm diagnosis of carcinoma of urinary bladder is cystoscopy and biopsy. Urine cytology is a non-invasive method of detecting carcinoma bladder. We aimed to evaluate the sensitivity and specificity of urine cytology to detect bladder carcinoma as a screening test. All patients with suspicion of carcinoma bladder with risk factors like increased age, symptoms of painless haematuria, dysuria and frequency attending the Urology out-patient department (OPD) of Patna Medical College and Hospital over a period of 3 years were screened. A total of 80 symptomatic patients were screened by cytology. 55 cases revealed abnormal cells in urine cytology. Out of these patients, 28 patients underwent cystoscopy and biopsy when deemed necessary. 13 cases of bladder carcinoma were diagnosed and confirmed by biopsy. Urine cytology was positive in 61.5% cases.
