Partial nephrectomy

Partial nephrectomy is a surgery where only the part of the kidney with cancer is removed, leaving the healthy part of the kidney intact. This procedure helps preserve kidney function.

Understanding the surgery

In metastatic kidney cancer, partial nephrectomy is not common. It may be considered in selected cases, such as:

  • When the tumour is small and located in an accessible area,
  • If you only have one functioning kidney, or
  • If protecting the kidney function is very important.

Your doctor will evaluate whether this surgery fits your case, often as part of a broader treatment plan that includes drug therapy.

Sometimes, a surgical robot is used to assist with laparoscopic surgery. Watch this video to see what a robot-assisted partial nephrectomy looks like.

Partial nephrectomy is a common surgery for kidney cancer that hasn’t spread. Most people stay cancer-free for years after the surgery. However, the chance of the cancer coming back depends on the type of tumour and the results of the laboratory examination (pathology). Keeping as much healthy kidney as possible helps your kidneys work well and supports your overall health.
