Intravenous Pyleogram (IVP or IVU)

• Usually an iodine compound

• No recover mechanism so it is pushed out by the kidney

• Cortical portion will be hit first, then the medullary area gets the definition.

• Next to the renal pelvis

• Then through the ureter and into the bladder with larger bladder complex

• This shows if there is filtration and asses RENAL FUNCTION

• Delayed enhancement or no enhancement

• If the above occurs we do a RUP

Retrograde Ureter Pyelogram

• Used with a catheder & camera (cystourethroscope)

• Could be a stone or renal artery dysfunction

CT scanning and arterography - this is the #1 3D imaging (CT)

• If the source of the urinary tract bleeding remains unknown, then CT scanning will be used to see collection point, leakage points, and other.

Renal Biopsy

• In some cases, glomerular lesions may require renal biopsy for definitive diagnosis

Lithotripter - can break up the calcium of a rib

• Used to break up stones

Laser -

• Has to be ventilated

Basket

• Grabs onto the stone to pull it out
