Multiple small stones trying to pass at the same time a.k.a. “Steinstrasse” or stone street
What is the main goal of imaging studies in individuals with kidney masses? What test should be ordered?
Determine if the mass is cystic, benign, or solid; Ultrasound or Pre/post contrast CT/MRI
What is the assumption with enhancing masses on the kidney?
RCCA
In a patient with painless hematuria and no renal masses detected, what study should be ordered?

- Post-Contrast: RCCA
- Delayed: Eval Collecting System Transitional Cell CA
Fat-containing renal mass?
