Cryotherapy, or freezing the prostate, is another treatment option for prostate cancer. Using ultrasound guidance, an urologist inserts a probe filled with liquid nitrogen through the skin into the prostate, which freezes the prostate tissue. Cryosurgery may require a hospital stay.
After the procedure, a supra-pubic tube or catheter is often used to rest the bladder for up to two weeks. Damage to the nerves and blood vessels around the prostate can cause complications. There is a possible risk of incontinence and impotence is very common.
