title: [The BTA test in the diagnosis of bladder tumors. Usefulness in the hospital setting].
abstract: We show our results in the diagnostic and follow-up of the bladder tumors comparing de BTA test with Void Cytology, in order to substitute this with the former. We performed BTA test, Void Cytology (of the same sample) and abdominal ultrasound to 133 patients. They are divided in three groups: 45 with bladder tumor, 16 healthy controls, 72 in follow-up with and without prophylaxis. The sensibility and specificity in tumor's group were similar. In controls' and follow-up's groups the void cytology specificity was superior. There is a high number of false positives in the follow-up group with a large number of "white" cystoscopes. A high number of false positives was seen if the BTA test was done in he first three months of follow-up. In the subgroup in prophylaxis with cystostatic there weren't false positives. We conclude that BTA test is useful in the diagnostic of bladder tumor but not in the follow-up, especially in the first three months.
