Medical Terminology Simplified

7–69 An intra/ven/ous pyel/o/gram (IVP) provides visualization of urinary

structures. It is used to assess the urinary tract and identify nephr/o/liths and

ureter/o/liths.

Determine words in this frame that mean

within a vein:____________________ / __________ / __________

record (x-ray) of the renal pelvis:__________ / _____ / __________

stones in the kidney:____________________ / _____ / ____________________

stones in the ureter:____________________ / _____ / ____________________

7–70 The prefix retro-means backward, behind.The suffix -grademeans to go.

The term retro/grade is used to describe a specific type of pyel/o/graphy.

Retro/grade pyel/o/graphy (RP) consists of radi/o/graph/ic images taken after a

contrast medium is injected through a urin/ary catheter directly into the urethra,

bladder, and ureters.

Identify two types of pyel/o/graphy.

Pyel/o/graphy in which a contrast medium is injected within a vein is called

____________________ / __________ / __________ __________ / _____ /

____________________ (__________).

Pyel/o/graphy in which a contrast medium is injected into the urethra is called

____________________ / ____________________ __________ / _____ /

____________________ (__________).

7–71 The nephr/o/scope, a fiber-optic instrument, is used to visualize the kidney

and remove ren/al calculi.

Use nephr/oto construct medical terms that mean

instrument for examining the kidney:

____________________ / _____ / ____________________

visual examination of the kidney:

____________________ / _____ / ____________________

7–72 Pyel/o/nephr/itis is a bacterial infection of the ren/al pelvis and kidney

caused by bacterial invasion from the middle and lower urinary tract or bloodstream.

Bacteria may gain access to the bladder via the urethra and ascend to the kidney.

Form medical words that mean

inflammation of the renal pelvis:__________ / __________

inflammation of the renal pelvis and kidney:

__________ / _____ / ____________________ / __________
