Before the procedure, you will be given medicine so that you do not feel pain. You may receive:

• A sedative to make you drowsy and numbing medicine on your perineum. This is the area between the anus and scrotum.
• Anesthesia. With spinal anesthesia, you will be drowsy but awake, and numb below the waist. With general anesthesia, you will be asleep and pain-free.

First, you will get a urinary catheter that will stay in place for about 3 weeks after the procedure.

• During the procedure, the surgeon places needles through the skin of the perineum into the prostate.
• Ultrasound is used to guide the needles to the prostate gland.
• Then, very cold gas passes through the needles, creating ice balls that destroy the prostate gland tissue.
• Warm salt water will flow through the catheter to keep your urethra (the tube from the bladder to outside the body) from freezing.

Cryosurgery is most often a 2-hour outpatient procedure. Some people may need to stay in the hospital overnight.

This therapy is not as commonly used and is not as well accepted as other treatments for prostate cancer. Doctors do not know for certain how well cryosurgery works over time. There is not enough data to compare it with standard prostatectomy, radiation treatment, or brachytherapy.

It can only treat prostate cancer that has not spread beyond the prostate. Men who cannot have surgery because of their age or other health problems may have cryosurgery instead. It also may be used if cancer comes back after other treatments.

It is generally not helpful for men with very large prostate glands.

Possible short-term side effects of cryotherapy for prostate cancer include:

• Blood in the urine
• Trouble passing urine
• Swelling of the penis or scrotum
• Problems controlling your urination (more likely if you have had radiation therapy also)
