What is kidney cryoablation?

What is kidney cryoablation?

Cryoablation uses extreme cold to destroy the kidney tumor, and is performed under local anesthesia as an outpatient procedure. A hollow probe (needle) is inserted into the tumor either through the skin or during laparoscopy. Very cold gases are passed through the probe, creating an ice ball that destroys the tumor.

How successful is cryoablation for kidney cancer?

Cryoablation is a procedure that ablates – or destroys – small kidney tumors using thermal energy to freeze them. This nonsurgical, minimally invasive procedure offers several advantages, including: An alternative treatment to removal of your entire kidney. A success rate of more than 90% for removing the cancer.

Is cryotherapy good for kidneys?

Cryotherapy is used to treat small, early stage kidney cancers less than 4cm across. For some people, it can cure the cancer without a kidney being removed. So it’s used for people who are not fit enough for surgery.

How long does it take to recover from kidney cryoablation?

While each person is different, most patients recover relatively quickly. Typically, patients spend only one night in the hospital or may even go home the same day, Most patients have fully recovered within a week or so.

What are the side effects of cryosurgery?

The risks associated with cryosurgery include:

  • blisters.
  • damage to nearby healthy tissue or vessels.
  • infection.
  • a loss of sensation if nerves are affected.
  • pain.
  • scarring.
  • ulcers.
  • skin discoloration.

Who performs cryoablation?

Cryoablation is performed by an interventional radiologist—a physician who uses image guidance, such as X-ray, ultrasound or CT scan, to treat cancer or other diseases in your body. During cryoablation, a thin, wand-like needle, call a cryoprobe, is inserted through your skin, directly into the cancerous tumor.

What are the side effects of a cryoablation?


  • Like any percutaneous procedure, bleeding may result—both from the puncture and the freezing of tissues such as the liver, kidney, or lung.
  • Damage to normal structures may occur.
  • If freezing occurs near the diaphragm, fluid can accumulate in the space around the lungs.

What are the side effects of cryoablation?

What are the risks or complications of cryoablation?

  • Bleeding.
  • Complications from anesthesia, such as trouble waking up or nausea.
  • Damage to surrounding structures.
  • Fluid collection in surrounding areas (for example, the lungs).
  • Infection from any opening in the skin.
  • Nerve damage leading to weakness or numbness.

What is cryoablation used for?

A procedure in which an extremely cold liquid or an instrument called a cryoprobe is used to freeze and destroy abnormal tissue.

How is cryosurgery done?

Cryosurgery freezes tissue, causing cells in the treated area to die. For tumors on the skin, the doctor applies liquid nitrogen directly to the abnormal area with a cotton swab or spraying device. For tumors inside the body, the doctor may use a device called a cryoprobe to freeze the tumor tissue.
