The 3 main functions are:
-Removes waste from the blood
-Maintains fluid and electrolyte balances
-Helps regulate blood pressure
The kidneys occupy the space between which vertebrae?
How much do the kidneys move with respiration?
Hoe much do kidneys move when going from a supine to an upright position?
What is the functional unit of the kidney?
UPJ and ureter
Which 2 areas are common sites for kidney stones to become lodged in the urinary tract?
The adult bladder can hold up to how much liquid?
The urge to micturate is felt when the bladder reaches what amount of fluid?
The inner lining of the bladder is covered with folds of tissue called:
The adrenal glands are part of what body system?
The main contraindication for this exam are patient's with diabetes, multiple myeloma, or high uric acid levels.
What is the normal range for blood urea nitrogen (BUN)?
What is the normal range for creatinine?
What is the normal range for glomerular filtration rate (GFR)?
-Passes urine from bladder to the outside of the body
-1.5 inches in women
-7-8 inches long in males
3 (Prostatic, urethral, and spongy)
The male urethra is divided into _____ parts.
-An Endocrine gland
-Produces and secretes adrenaline (epinephrine), norepinephrine, dopamine and corticol hormones
How much contrast media is usually injected for an IVP procedure?
During an IVP, these may be required to see at different time intervals and at different levels of contrast through the kidneys.
The greatest concentration of contrast media in the kidneys occurs how long after injection?
For an IVP, the main reasons to do one are:
-Location of urinary structures
-Patient prep (no feces in bowel)
-To visualize calcified stones
-Positioning for radiographer
During an IVP, we may need to use these to increase the pressure and visualize the ureters (by slowing the flow).
Nearly all life threatening contrast reactions occur in the first ___ minutes.
a general term for radiographic
investigation of the renal drainage and
collecting system which requires injection of
iodinated contrast material.
Intravenous pyelogram (IVP)
-Is a Functional study of the urinary system
-An Antegrade procedure
-Iodinated contrast material is introduced
-Contrast is conveyed through the bloodstream to the kidney and is removed from the blood during the normal filtration process
-The contrast is then excreted down the ureters and into the bladder in the urine.
Patient prep for an IVP
-For an unobstructed view of the urinary
tract, the bowel should be free of gas and solid material.
-Low-residue diet given for 1-2 days prior.
-Laxative given the evening prior.
-A light meal on the evening prior to the
-NO FOOD for 12 hours prior, only water.
calcified pelvic vein that can often resemble kidney stones
The initial phase after injection when the kidneys first begin to highlight on the images is called the:
What degree of obliquity is used to demonstrate the kidneys?
Which kidney is parallel to the IR with the patient in LPO position?
Which kidney is perpendicular to the IR with the patient in LPO position?
Which kidney is parallel to the IR with the patient in RPO position?
Which kidney is perpendicular to the IR with the patient in RPO position?
The 3 reasons why we do the ______________ picture of the bladder with the patient in the upright position is:
-to show mobility of the kidneys
-ability to empty
Common allergic reactions
Warmth, flushing, metallic taste, N/V, coughing
*No treatment is necessary
Intermediate allergic reactions
Erythema, urticarial, and bronchospasm
*You must Notify physician and prepare antihistamine if ordered

Respiratory or cardiac arrest, seizure, hypotension, throat constriction, feeling
of doom, wheezing, and may be fatal
*You must Maintain airway, call a code, and treat for shock

small, hard mineral deposits that form inside the kidney
Ascending limb of henle's loop
Descending limb of henle's loop
distal convoluted tubule
proximal convoluted tubule
contractions in the ureters that work to
move urine and debris down to the bladder
Kidneys normally excrete ________ liters of urine per day.
The ________ kidney sits lower due to the size and position of the liver.
Is a common location for kidney stones to become lodged.
-10-12 inches long
-Conveys urine from kidneys to bladder by means of peristalsis
-Extends from the renal pelvis to the uterovesicular junction.
area of Trigone
-Only spot that does not have rugae
-the 2 UVJs and the urethra make a triangle
