5. Renal Pelvis and Ureter T3 for renal pelvis only (top of diagram) is defined as tumor that invades beyond muscularis into peripelvic fat or the renal parenchyma. T3 for ureter only (bottom of diagram) is defined as tumor that invades beyond muscularis into periureteric fat. Compton, C.C., Byrd, D.R., et al., Editors. AJCC CancerStaging Atlas, 2nd Edition.

6. Renal Pelvis and Ureter (A) T4 is defined as tumor that invades adjacent organs, or through the kidney into the perinephric fat. Here, the tumor invades the vertebral body.

7. Renal Pelvis and Ureter T4 for the ureter is defined as tumor that invades adjacent organs. On the left, the tumor invades the iliac vessels. On the right, the tumor invades the bladder.
