Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
Transrectal biopsy is a biopsy procedure in which a sample of tissue is removed from the prostate using a thin needle that is inserted through the rectum and into the prostate. [1] Transrectal ultrasound (TRUS) is usually used to guide the needle. [2] [3] The sample is examined under a microscope to see if it contains cancer.
Prostate cancer antigen 3 is a urine test that detects the overexpression of the PCA3 gene, an indicator of prostate cancer. [32] [46] [47] [44] ConfirmMDx is performed on tissue taken during a prostate biopsy. The test identifies men with clinically significant prostate cancer who would benefit from further testing and treatment.
Physical examination including a digital rectal examination and routine blood tests are carried out. At least six transrectal ultrasound guided biopsies taken from different zones of the prostate are usually obtained. Other considerations include bowel preparation the day before surgery and taking antibiotics.

If the patient is lying on their side, the physician will usually have them bring ...
One common procedure is the digital rectal examination, in which a doctor inserts a lubricated finger into the rectum to feel the nearby prostate. [23] [24] Tumors feel like stiff, irregularly shaped lumps against the rest of the prostate. Hardening of the prostate can also be due to benign prostatic hyperplasia; around 20–25% of those with ...
