title: [Transretcat aspiration biopsy in the diagnosis of prostatic cancer (author's transl)].
abstract: In almost three years 853 prostatic aspirates obtained from 709 patients were cytologically examined. In 313 patients we also made histological examinations. The cytologic diagnosis could be checked by histology in 288 untreated patients. The cytologic diagnosis  of prostatic cancer was confirmed by histology in 65.3% and was false negative in 28.3%. In 6.4% the cytologic material was unsatisfactory for cytologic examination. Considering cytologic findings after repeat aspiration biopsy the accuracy of the cytologic method was 71.7%. The detection rate of prostatic cancer is about 20% higher using both, cytologic and histologic methods, than using cytology or histology, only.
