Cryosurgery uses small needles (similar to the ones used to draw blood) to form ice balls that are up to five centimeters in length.
These extremely cold temperatures are able to kill prostate or kidney cancers. Several studies reported an acceptable oncological outcome and low morbidity.
In a kidney cryoablation procedure, cryosurgery is done by laparoscopic guidance under general anesthesia.
Renal lesions are biopsied (one to three cores) under laparoscopic ultrasonographic guidance using an 18 gauge biopsy needle before ablation. Then, cryoneedles and thermal sensors are placed into the kidney tumor laparoscopically.
Additionally, the iceball is monitored using real-time ultrasonography during the operation, ensuring destruction of the entire tumor as well as the desired margin of surrounding tissue.
These apply to populations of patients in general, but the individual patient may have a different experience.
Potential candidates for kidney cryoablation are those patients:
