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.
Correlation between biopsy and final pathology is improved between MRI-guided biopsy as compared to TRUS. [14] In the fusion MRI-US prostate biopsy, a prostate MRI is performed before biopsy and then, at the time of biopsy, the MRI images are fused to the ultrasound images to guide the urologist to the suspicious targets. Fusion MRI-US biopsies ...
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 ...
Men with acute prostatitis often have chills, fever, pain in the lower back, perineum, or genital area, urinary frequency and urgency often at night, burning or painful urination, body aches, and a demonstrable infection of the urinary tract, as evidenced by white blood cells and bacteria in the urine.
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.
When they retired, the Leedys lived in Alexandria, Virginia, an affluent, high-cost Washington, D.C., suburb. “My mother was 92, and we knew we had to have her live with us, as she could not ...
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). Calcification is also found in a variety of other conditions such as prostatitis, chronic pelvic pain syndrome, and prostate cancer.
