Transrectal ultrasonography in prostatic cancer: interexaminer variability of interpretation.

Objective: To compare the variability of transrectal ultrasonographic (TRUS) interpretation for the decision of performing biopsies and the lesions to biopsy.

Methods: We extracted at random from our videotape database 16 records of patients who had undergone biopsies, added 2 normal glands and duplicated 2 of these 18 records. Based on the records, 5 well-trained physicians had to describe the images on the tape, and to decide whether or not to biopsy the prostate.
