5. Catheter Types
Foley catheter: Retained
via a balloon injected
with sterile water, which
allows for long-term
catheterization.
Used in most cases.Irrigation ports
useful when blood
clots are present .
Used in males with an
enlarged prostate.

6. Catheter types continued…
Texas catheter: Used for male
patients only. Less risk of an
infection than an indwelling
catheter.
Straight catheter: Does not
have a balloon. Used for
short-term catheterization.

7. ESWL – extra corporeal
shockwave lithotripsy
•A non-invasive , therapeutic procedure whereby renal
calculi (kidney stones) are crushed from the outside of
the body, utilizing a directed, acoustic pulse.
•Ideally, the pulverized remains are passed in the urine.

9. BUN – blood urea nitrogen
•A diagnostic procedure used in order to determine
how well the kidneys are functioning by measuring
blood levels of urea.

10. BUN continued…
• Urea is formed as an end product of
protein catabolism.
• Is normally excreted by the kidneys
through the urine.
• A critical range of 100mg/dL
indicates serious impairment of the
kidneys.

11. IVP – intravenous pyelogram
•A visual record in the form of an x-ray.
•Obtained by the injection of a contrast
medium into a vein, so as to make the renal
calyces, renal pelvises, ureters, and urinary
bladder more prominent on the x-ray.

12. CRF – chronic renal failure
•A condition where increased levels of
urea and other waste products are
retained in the blood due to chronic
kidney dysfunction.
Example of enlarged, polycystic
kidney on left, normal on left.
Enlarged polycystic kidneys

13. CRF continued…
•Early signs include: sluggishness, fatigue, and
mental dullness.
•Late signs include: anuria, convulsions, GI
bleeding, malnutrition, neuropathy, types of
anemia, and yellowing of the skin.
•Long-term hemodialysis or peritoneal dialysis is
often initiated.
•Kidney transplantation is often considered.
