Transrectal needle aspiration versus transperineal needle biopsy in diagnosis of carcinoma of prostate.

Transrectal needle aspiration of the prostate was compared to transperineal biopsy in 28 patients with suspected carcinoma of the prostate. This technique was found to have a high sensitivity and specificity for diagnosing carcinoma of the prostate, and no complications were seen. The addition of Nuclear Flow DNA analysis may give further prognostic information from needle aspiration and core biopsy specimens. Transrectal needle aspiration of the prostate is a safe, inexpensive, and accurate method of diagnosing carcinoma of the prostate.
