Things to know before you undergo nephron sparing surgery
Not all surgeries are without complications, and each surgery has a unique set of complications
Before going for Nephron sparing surgery (removal of only the tumor, not the whole kidney), you should know that
- Local recurrence (coming back in the kidney area) of the cancer is higher than if we remove the whole of the kidney (5-10% vs 1-2%). But studies have shown that it doesn’t make a difference on overall survival. Potential benefit of Nephron sparing surgery might overweigh this disadvantage and it may be worth the whole exercise.
- There is a chance of urinary leak from the remaining part of the kidney (to outside the kidney) which might need a “stent” inside the body which drains the urine via the right path (Kidney to bladder). We might need to keep this stent for 6 weeks or even more. Most urine leaks out of the kidney resolve with a stent.
- You may need more intensive follow up in the OPD than you would if we remove whole of the kidney. That might mean 2 additional visits per year.
