The energy from the probe heats the abnormal prostate tissue without damaging the urethra. 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]
Treatment for prostate cancer may involve active surveillance, surgery, radiation therapy – including brachytherapy (prostate brachytherapy) and external-beam radiation therapy, proton therapy, high-intensity focused ultrasound (HIFU), cryosurgery, hormonal therapy, chemotherapy, or some combination.
The use in prostate and renal cryoablation are the most common. Although sometimes applied in cryosurgery through laparoscopic or open surgical approaches, most often cryoablation is performed percutaneously (through the skin and into the target tissue containing the tumor) by a medical specialist, such as an interventional radiologist .
Cryosurgery (with cryo from the Ancient Greek κρύο ' icy cold ') is the use of extreme cold in surgery to destroy abnormal or diseased tissue; [1] thus, it is the surgical application of cryoablation. Cryosurgery has been historically used to treat a number of diseases and disorders, especially a variety of benign and malignant skin ...
Following the procedure, the prostatic tissue will be swollen and irritated. Urologists often place a Foley catheter to prevent the patient from having urinary retention. After three to five days the Foley catheter can be replaced by a temporary prostatic stent to improve voiding without exacerbating irritation symptoms.

Prostate laser surgery is used to relieve moderate to severe urinary symptoms caused by prostate enlargement. The surgeon inserts a scope through the penis tip into the urethra. A laser passed through the scope delivers energy to shrink or remove excess tissue that is preventing urine flow. [7] Different types of prostate laser surgery include:
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.
