Prostate biopsy is commonly performed in association with a prostate ultrasound to confirm or rule out prostate cancer. During the procedure, an ultrasound probe is placed in the rectum to visualize and measure the prostate. After the imaging portion of the procedure, a small biopsy needle is passed through the probe to obtain several samples of prostate tissue. The procedure can be completed in 3-5 minutes. Patients should be off all blood thinners prior to the procedure to minimize the risk of infection. Enemas are sometimes recommended to improve the quality of the ultrasound image but have not been shown to lower the risk of infection.
