What are the side effects of cryoablation?
Cryotherapy is an effective and safe treatment, but there is a risk of tumour cells being left behind. For kidney cancer and prostate cancer, this means the tumour is more likely to come back (recurrence) than after surgery. There are also risks of complications.
For kidney cancer, the most common complications include bleeding and a build-up of blood inside the kidney, known as perinephric haematoma. During treatment, your ureter, spleen, liver, or bowel may be injured. You could also experience paraesthesia, which is a prickling or tingling sensation of the skin, around the treated area.
By using ultrasound images or (sometimes) MRI images, the cryotherapy needles can be placed very accurately. That ensures that only the tumor is treated. As a result, surrounding tissue can be spared and side effects are avoided as much as possible. Therefore, side effects are reported little.
