Role of urinary cytology in the study of bladder cancer. Comparison with the BTA test

: Early diagnosis of bladder neoplasia at the moment makes use of urinary cytology and cystoscopy. The authors describe the results of a study on 62 patients (56 men and 6 women) with bladder neoplasia, and compare the results of urinary cytology to the BTA test (Bladder Tumor Antigen test), ones, after considering histological results of TURB (Trans Urethral Resection Bladder) or cystectomy. Sensibility of urinary cytology was quite better than BTA test sensibility (80.6% vs 48%). Finally it's described a study on 450 cases of istologically controlled bladder carcinomas, on which had been executed a cytological analysis before surgical treatment. The outcome of cytological diagnosis on 414 cases (92%) was neoplasia. On the basis of their experience, the authors regard cytology as a fundamental method in diagnostic iter and in follow-up of patients with bladder neoplasia.
