FNAC and transabdominal ultrasonography in the diagnosis of prostatomegaly.

Transrectal fine needle aspiration cytology (FNAC) was performed in 100 cases of prostatomegaly detected by digital rectal examination (DRE). The cytologic findings were compared with histolgic findings of material obtained by transurethral resection of prostate (TURP) in 84 of the cases. In addition, pre-prostatectomy transabdominal ultrasonography was done in 55 of the cases and the findings were compared with cytologic and histologic diagnoses. The accuracy of diagnosis by FNAC for benign lesions and carcinoma of prostate was 98.33% and 81.81% respectively. The accuracy of transabdominal ultrasonography for benign lesions was 91.66% but that for carcinoma was only 38.46%. The technique of transrectal FNAC was found to be simple quick, economical and easy to repeat with high accuracy and was suitable for outpatients.
