Before the exam, the person will need to drink three glasses of water (about 500 ml) at least one hour before the exam. If the person is on fluid restriction diet (due to heart, liver or kidney problems), then he can ignore the instruction. If there is a urinary catheter, the catheter should be clamped immediately after drinking the water. The ...
Under ultrasound guidance metal rods are inserted through the skin of the perineum into the prostate. Highly purified argon gas is used to cool the rods, freezing the surrounding tissue at −186 °C (−302 °F). As the water within the prostate cells freezes, the cells die. The urethra is protected from freezing by a catheter filled with warm ...
The evidence from this review with a 12-month follow-up is very uncertain if aquablation leads to similar rates of serious side effects or a similar need for retreatment when compared to transurethral resection of the prostate. Aquablation may lead to fewer ejaculatory problems, but no difference in erectile function.
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]
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.
Because water is an excellent conductor for ultrasound waves, visualizing these structures often requires a well-filled urinary bladder (this means the patients has to drink plenty of water before the examination). The liver can be imaged by swiping the probe sagittally from medial to lateral at the subcoastal region.
As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. It has been the standard treatment for BPH for many years, but recently alternative, minimally invasive techniques have become available. [1] This procedure is done with spinal or general anaesthetic.
Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. [1] [2] When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates. [2] Screening precedes a diagnosis and subsequent treatment.
