Abstract
We reviewed 225 men who were followed for 2 to 21 years by periodic rectal examination in an effort to detect prostatic cancer without the glands having been sufficiently suspicious for biopsy to have been recommended. These patients underwent further evaluation with transrectal prostatic ultrasonography and serum prostate specific antigen determinations. When appropriate, ultrasonically guided transrectal needle biopsy of the prostate was performed without analgesia, anesthesia or prophylactic antibiotics. This is a simple, safe and effective means to obtain tissue for diagnosis. Recommendations for the current applicability of these diagnostic modalities by the practicing urologist are given.
