What are the major indications for partial nephrectomy in patients with RCC?
Partial nephrectomy is used whenever possible to maximally preserve renal function. It is predominantly used when there is:
- • Tumor size <4 cm (although some surgeons will treat tumors up to 7 cm in size with nephron sparing techniques).
- • Peripheral tumor location.
- • Polar tumor location.
- • Lack of renal sinus fat or collecting system involvement by tumor.
- • Lack of venous extension of tumor.
- • Presence of contralateral renal disease.
- • Presence of a solitary functioning kidney.
