EOD Primary Tumor
This input is used for staging
Notes
**Note 1:** Gerota's fascia is a fibrous tissue sheath surrounding the kidney and suprarenal or adrenal gland. The perirenal fat, renal capsule, and renal parenchyma lie below the fascia. **Note 2:** The most common site for renal parenchymal cancer to develop is in the proximal convoluted tubule. Tumor extension from one of these structures into another is coded 100 and is dependent on size in the absence of further involvement.Default
