Transrectal thin-needle aspiration biopsy of prostate: four years' experience.
Fine-needle aspiration biopsy of the prostate is of great advantage in the diagnosis of prostatic disease. The procedure is quick, safe, and reliable. Several aspirations can be done even in outpatients with minimum trauma. Complications are rare. In this study cytologic diagnosis was obtained in 511 consecutive patients. To evaluate the cytologic accuracy, 195 cytologic diagnoses were compared with histologic findings obtained from transperineal biopsy on the same patients. Correlation was achieved in 96.42 per cent of these cases. The findings in 127 histologically graded prostatic cancers were compared with the cytologic differentiation observed in aspiration smears of the same patients. Cytologic grading of prostatic carcinoma corresponded to the histologic grading in 85.8 per cent of the cases.
