transrectal การใช้

• Currently, most prostate biopsies are performed using transrectal ultrasonography ( TRUS ).
• A transrectal ultrasound may also be used.
• Transrectal ultrasonography creates a picture of the prostate using sound waves from a probe in the rectum.
• Men with elevated PSAs often need physical examinations, transrectal ultrasound and biopsies to make an accurate diagnosis.
• According to RadiologyInfo, ultrasounds are useful in the detection of rectal ( transrectal ) ultrasound in men.
• In the transrectal procedure, an ultrasound probe is inserted into the rectum to help guide the biopsy needles.
• Defecography, sigmoidoscopy, transrectal ultrasound, mucosal biopsy, anorectal manometry and electromyography have all been used to diagnose and study SRUS.
• The treatment is administered through a transrectal probe and uses heat generated by focusing ultrasound waves to kill cancerous cells in the prostate.
• Scrotal and transrectal ultrasonography ( TRUS ) are useful in detecting uni-or bilateral congenital absence of the vas deferens ( CBAVD ), which may be associated with abnormalities or agenesis of the epididymis, seminal vesicles or kidneys, and indicate the need for testicular sperm extraction.
• Attempts are sometimes made to diagnose an ejaculatory duct obstruction by means of medical imaging, e . g . transrectal ultrasound or MRI, transrectal needle-aspiration of the seminal-vesicles 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.
