Questions to think of Questions to think of
Which diagnostic imaging modality is the most
suitable for the urinary system and why?
What urinary diseases are suitable for imaging
examination?
What imaging method should be chosen with
different sort of disease considered clinically?
What information we expect to get from the
imaging?

Imaging modalities:Imaging modalities: plane film （ KUB ） -limited effective Urography
Intravenous pyelography IVPRetrograde pyelographyCystographyUrethrography -show morphous of the lumen indirectly
-overall view of the urinary tract -affected by the renal function & lumen constructi
on Ultrasonography USG
-real time, convenient, low cost, available -good characteristic of stone, fluid
CT Computed Tomography -high resolution of high density & low density
-contrast enhancement MRI Magnetic Resonant Imaging
-good contrast of soft tissues

How to chose imaging exam for the patient with gross hematuria (how to determine the method and purpose of next exam according to the result of pre-exam)?
What is the pathologic underlying of the various manifestations of renal carcinoma with different imaging method?
What imaging method is the first chosen for the prostate exam?
