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.
During the transrectal procedure, an ultrasound probe is inserted into the rectum to assist in guiding the biopsy needles. Following this, a local anesthetic, such as lidocaine, is administered into the tissue surrounding the prostate. Subsequently, a spring-loaded biopsy needle is inserted into the prostate, resulting in a clicking sound. When ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Prostatic calculi (PC), prostatic stones, prostatic calcification or prostatic lithiasis, are hyper-echoic mineral deposits in the prostate that are frequently detected incidentally during transabdominal ultrasonography, transrectal ultrasonography, or computed tomography. [1] [2] [3]
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.
However, transrectal ultrasound has a relatively low sensitivity of approx. 50% and thus is only a tool to rule-out cysts in the region of the orifices but is not sufficient to rule out an obstruction of the ejaculatory ducts due to other causes. In approx. 50% of cases of unexplained low-volume azoospermia MRI and TRUS do not reveal any ...
