17
Q

Staghorn calculi

A

19
Q

Test of choice to exclude urinary tract obstruction

A

Renal ultrasound

20
Q

Renal ultrasound can identify

A 
Renal cysts (PCKD) and masses 
Hydronephrosis

Etc

21
Q

Non-invasive test to eval for renal blood flow

A

Doppler ultrasound

22
Q

Hypodense mass with internal echoes on ultrasound

A

A

Intravenous pyelogram (IVP)

  • not used as often because better tests available
28

Bladder cancer work up (if hematuria)

A

1) IVP
2) urine cytology
3) cytoscopy
