Radiographic Pathology Chapter 7:
Urinary System
What does the urinary system consists of? correct answers 2 kidneys
2 ureters
urinary bladder
urethra
Whats the function of the urinary system? correct answers to remove waste from the
bloodstream for excretion
How much excretion is release per day? correct answers 1 to 1.5 L of urine
Whats retroperitoneal and level of T12-L3? correct answers Kidneys
The function that is responsible for forming urine? correct answers Nephron
These extend from kidneys to bladder and 10 inches in length and drain urine for
kidneys to bladder correct answers Ureters
What acts as a reservoir for urine (muscular and capable of distention)? correct
answers Urinary bladder
What extends from bladder to exterior? correct answers Urethra
This passes thru prostate gland and also serves as part of the reproductive system.
correct answers Male Urethra
What is found with abnormal lab clinical findings such as polyuria, oliguria, dysuria,
abnormal urine color, black pain, or obstructive symptoms? correct answers Urinary
disorders
Polyuria correct answers frequent urination
Oliguria correct answers low urine output
Dysuria correct answers discomfort when urinating
Creatinine normal levels correct answers .6 to 1.5 MG/DL
BUN normal levels correct answers 8 to 25 MG/DL
, If either the creatinine/BUN level are abnormal what must NOT be injected? Who must
you consult for this? correct answers Contrast
Radiologist
What does radiography demonstrate? correct answers -KUB
-size and location of kidneys
- adequate bowel
preparation
-radiopaque calculi of
kidneys, ureters, or bladder
This procedure is use to assess the urinary system in timing sequence and indications
are obstruction, hematuria, systemic hypertension, porstatism. correct answers
Intravenous Urography (IVU)
Where are stones commonly located? correct answers UV Junction
The most common exam for lower urinary tract which is performed retrograde and the
indications are vesicoureteral reflux MOST COMMON. correct answers Cystography
___________: patient already has an existing supra-pubic catheter.......contrast injected
to visualize proximal portion of urethra correct answers Ante grade Urethrography
_______________: placed to drain urine from bladder when patient cannot urinate
normally correct answers Supra-pubic catheters
_____________: inserting a catheter into the urethra, injecting contrast to visualize
distal or all of the urethra correct answers Retrograde Urethrography
This procedure is performed by urologist during cystoscopy and indications are
hematuria, hydronephrosis, nonfunctioning kidney. correct answers Retrograde
pyelography
Imaging modality of choice for most renal disorders
Noninvasive: evaluates both functioning and nonfunctioning kidneys
Indications: kidney transplant, assessing blood flow, detecting anomalies in fetus before
birth correct answers Sonography
What is preferred over radiography, able to detect small differences, kidneys can be
seen with or without contrast and what are the indications? correct answers CT
Indications: renal masses, obstructions due to stones
