Staging

Criteria for TNM Clinical Staging:
Physical examination and history, histologic confirmation of tumor, urinary endoscopy, urinary cytology, pyelography, imaging (radiographic and computer assisted), and other evaluations to determine metastatic involvement; laparotomy may be included in clinical staging.

Criteria for TNM Pathologic Staging:
Radical nephrectomy, including removal of the primary tumor, entire kidney, adrenal gland, perinephric fat, Gerota's fascia, renal vein and lymph node resection are required for pathologic staging. For renal pelvis and ureteral cancers, the ureter and a portion of the bladder (bladder cuff) should also be resected.
