Imaging Modalities of Urinary System (I)KUB(Kidney-ureter-bladder survey) a plain film of the kidneys and bladder. Useful for the diagnosis of calculi, soft-tissue calcifications and gas Should always be performed prior to contrast medium injection
Imaging Modalities of Urinary System （Ⅰ） KUB (Kidney-ureter-bladder survey) • A plain film of the kidneys and bladder. • Useful for the diagnosis of calculi, soft-tissue calcifications and gas. • Should always be performed prior to contrast medium injection

Excretory Urography IVP( Intravenous Pyelography After KUB, contrast medium is injected into a vein Films taken 1, 15 and 30 min post contrast Abdominal compression is applied in order to retain the opacified urine in the pelvis and ureter The compression is then removed and a full abdominal exposure is obtained
IVP ( Intravenous Pyelography ) • After KUB, contrast medium is injected into a vein. • Films taken 1,15 and 30 min. post contrast. • Abdominal compression is applied in order to retain the opacified urine in the pelvis and ureter. • The compression is then removed and a full abdominal exposure is obtained. Excretory Urography
Excretory Urography IVP( Intravenous Pyelography Clinical application Rapid overview of the entire urinary tract Detailed anatomy of the collecting system Important for the diagnosis of early transitional cell carcinoma in the upper urinary tract. Congenital anomalies such as fusions rotation anomalies, calyceal variants and duplications are well demonstrated by IVP Indication: Normal renal function; No iodine allergy
