Clinical T

This input is used for staging

Notes

**Note 1:** Assign pTa or pTis for in situ cases (behavior code /2). **Note 2:** In case of multifocal noninvasive Ta and Tis tumors, assign pTis. **Note 3:** Tumor involving both renal pelvis and ureter (unifocal or multifocal) is classified by the depth of greatest invasion in either organ for TNM staging. * Assign T1 for tumor involving the wall of both renal pelvis and ureter **Note 4:** Direct invasion of the bladder by a ureteral tumor is classified by the depth of greatest invasion of the bladder or ureter for TNM staging.
