Table 4. Predicted (left) and actual (right) probabilities (%) of muscle-invasive UTUC or NOC-UTUC as a function of preoperative grade and parenchymal invasion.

Preoperative grade
Low High
Muscle-invasive UTUC:
 No local invasion on imaging 25/26 49/49
 Local invasion on imaging 54/40 78/82
NOC-UTUC
 No local invasion on imaging 11/13 32/31
 Local invasion on imaging 39/20 71/76

Local invasion on imaging = parenchymal, renal sinus fat or periureteric invasion.
