The Department of Urology at Mayo Clinic has long been at the forefront of research on partial nephrectomy, also called kidney-sparing surgery. Mayo Clinic studies suggest that:

  • People with kidney cancers smaller than 1.5 inches (about 4 centimeters) have a significantly higher 10-year survival rate compared with those who had their entire kidney removed.
  • In more-advanced stages of local cancers, outcomes and survival rates appeared similar for people whether they had a partial nephrectomy or a radical nephrectomy.
  • Restriction of the blood supply (ischemia) has little effect on long-term kidney function after partial nephrectomy.
  • Experienced surgeons can achieve good outcomes with minimally invasive partial and radical nephrectomies, reducing the need for open surgery.

Survival rates also appear to relate to surgical training, experience and expertise.
