Cryoablation destroys a small kidney tumour by freezing it with needle-like probes placed through the skin under CT or ultrasound guidance. An ice ball forms around the probe tips and kills the tumour cells, and the dead tissue is slowly reabsorbed.
It treats tumours under about 3 to 4 cm while preserving nearly all kidney function and avoiding major surgery. Local recurrence is somewhat more common than after partial nephrectomy, so regular follow-up scans are part of the treatment.
What Cryoablation for Kidney Tumours involves
A biopsy is taken beforehand or at the start of the session, since around 1 in 5 small kidney masses is benign. You lie on your front or side in the CT scanner. The interventional radiologist inserts two to five probes of 1.5 to 2.4 mm through the skin of the back or flank into the tumour, spaced to cover it. If bowel or ureter lies close, fluid or gas is injected to push it to safety. Argon gas cools the probe tips to below minus 40 degrees Celsius for about 10 minutes, followed by a thaw and a second freeze. The growing ice ball is clearly visible on CT and is extended 5 to 10 mm beyond the tumour edge. The probes are warmed and withdrawn, and a final scan checks for bleeding.
Who is a good candidate for Cryoablation for Kidney Tumours?
It is aimed at small tumours in people for whom surgery is less attractive.
- A solid kidney tumour of up to about 3 cm, and selected tumours up to 4 cm
- Older people or those with heart, lung or other illness that raises surgical risk
- A single kidney or reduced kidney function
- Hereditary conditions such as von Hippel-Lindau disease, with multiple tumours over time
- Recurrence after previous partial nephrectomy
It is usually not the right choice if:
- Tumours over 4 cm, where control rates fall
- Tumours sitting centrally against the collecting system or main vessels, depending on anatomy
- Young, fit patients, for whom partial nephrectomy has the strongest long-term evidence
- Uncorrectable bleeding disorders
- Very small masses in frail, elderly people may simply be watched (active surveillance)
Technique options
- Percutaneous CT-guided cryoablation: The usual approach, under sedation or a light general anaesthetic.
- Laparoscopic cryoablation: For tumours at the front of the kidney, close to bowel.
- Radiofrequency or microwave ablation: Heat-based alternatives with similar outcomes for small tumours.
- Robotic partial nephrectomy: The surgical standard, with the lowest local recurrence rate.
- Active surveillance: Serial imaging for small, slow-growing masses.
What happens during your treatment
The session takes 1.5 to 2.5 hours under conscious sedation or general anaesthetic. There is no incision, only needle marks. Most people stay one night for observation and a blood count the next morning.
Preparing for your trip
A single session is normal. Plan about 5 to 7 days in the city: review of your scans, biopsy if it has not been done, treatment, a night in hospital and a check before flying. Follow-up CT or MRI is needed at about 3, 6 and 12 months and then yearly for at least 5 years; this can be done at home if the images are shared.
- Tell the doctor about medication, allergies, pregnancy or breastfeeding, and any history of cold sores, keloid scars or autoimmune disease
- Avoid alcohol, aspirin and anti-inflammatory painkillers for a few days beforehand if your own doctor agrees, to reduce bruising
- Arrive without make-up on the treatment area and avoid sunbeds and strong sun for two weeks before
Recovery and results
Flank soreness lasts a few days, and blood may appear in the urine for a day or two. Avoid heavy lifting and strenuous exercise for 1 to 2 weeks. Desk work can resume in 3 to 5 days. On follow-up imaging the treated area should not take up contrast and should shrink gradually; any enhancing nodule suggests residual tumour, which can be re-treated.
- Back to everyday activity: 3 to 7 days
- When results show: First check scan at about 3 months
- How long they last: Tumour control about 90 to 95 in 100 at 5 years for small tumours
Safety, risks and revision policy
Major complications occur in a small percentage of cases.
- Bleeding around the kidney, occasionally needing transfusion or embolization
- Incomplete treatment or local recurrence in roughly 5 to 10 in 100, often suitable for repeat ablation
- Injury to the ureter, bowel or nearby nerves causing flank numbness or pain
- Collapsed lung when the path passes near the chest
- Urine leak
- Infection, which is rare

Frequently Asked Questions
Is freezing as good as surgery?
For tumours under 3 cm, cancer-specific survival is similar. Local recurrence is slightly higher but usually re-treatable. For larger tumours, surgery is better.
Do I need a biopsy first?
It is strongly recommended. It may show a benign tumour that needs no treatment, and it guides follow-up.
Will my kidney function suffer?
The loss is minimal, which is one of the main reasons for choosing ablation.
