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.
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.
The procedure may be performed transrectally, through the urethra or through the perineum. The most common approach is transrectally, and historically this was done with tactile finger guidance. [3] The most common method of prostate biopsy as of 2014 was transrectal ultrasound-guided prostate (TRUS) biopsy. [4]
Before the operation, an assessment of life expectancy is made. 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 ...
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.
Now, with the exclusive adoption of JointVue’s OrthoSonic 3D Surgery Planning Technology for Smith+Nephew implants, surgeons have access to an additional procedural solution that utilizes ultrasound to generate a 3D plan within minutes. This radiation-free, automated planning tool guides surgeons to tailor the procedure uniquely to each patient.
A drug test had turned up traces of benzodiazepine — the very medication that staff had administered before wheeling her into surgery. For Victoria Villanueva, pregnant with her first child, the ...
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.
