The reliability of urinary cytology in the detection of tumours of urinary bladder.
Detection of urinary bladder tumours by cytological examination of urine was carried out on 193 patients suffering from haematuria. The patients comprised 149 new cases and 44 follow-up cases previously diagnosed as bladder cancer. Urinary bladder malignancy was detected in 72 of new cases and 20 of follow-up cases by cytological examination of urine. Reliability of the findings was checked by histopathological examination of the biopsy material removed from bladder by cystoscopy which detected malignancy in 84 of new cases and 16 of follow-up cases. Thus the sensitivity of cytological examination of urine in detecting bladder malignancy was 92% and specificity of 88%. False positive result was 4% and false negative result was 12%.
