Technique of TRUS

Technique of Transrectal Ultrasound (TRUS)

  • The doctor starts by examining the prostate by inserting his gloved finger into the rectum
  • Then the ultrasound probe is covered by a condom.
  • It is then inserted into the rectum and detailed visualization of the prostate is started. The examination usually takes 5 – 10 minutes after which the doctor will give you a report and some ultrasound pictures.
  • The report will include the size of the prostate, and whether there are any dark areas within the prostate. These dark areas are called “hypoechoic lesions” and they may denote the presence of a tumor and the doctor will arrange to take samples from the prostate in this case (called biopsies). Samples or biopsies may be taken in the same setting if the patient is under antibiotic coverage. If not, biopsies are postponed till proper preparation for biopsies is performed
