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.
The most common method of prostate biopsy as of 2014 was transrectal ultrasound-guided prostate (TRUS) biopsy. [4] Extended biopsy schemes take 12 to 14 cores from the prostate gland through a thin needle in a systematic fashion from different regions of the prostate. [5]
A further transurethal method utilizes a robotically-controlled waterjet to remove prostate tissue. Visualization is provided by a combination of cystoscope and transrectal ultrasound methods. This procedure claims risk reduction advantages as a result of being heat free.
Prostate size of 30 cc or more indicates enlargement of the prostate. [53] Prostatic calcification can be detected through transrectal ultrasound (TRUS). Calcification is due to solidification of prostatic secretions or calcified corpora amylacea (hyaline masses on the prostate gland).
Transrectal biopsies, the more common type, involve inserting a needle through the rectum to obtain tissue samples. However, they may not accurately sample the entire prostate, increasing the risk of missed diagnoses, and have a higher risk of infection due to the insertion through the rectum.
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.
The resulting scar tissue later atrophies, reducing the size of the prostate which in turn reduces the constriction of the urethra. It can be done with a local anesthetic on an outpatient basis. [1] It takes about an hour to perform the procedure. [2] It takes about 30 days for the ablated prostate tissue to resorb. [3]
