Flashcards in Urinary Tract Obstruction Deck (12):
1

3 most common places for obstruction

utereopelvic junction, illiac vessel crossing, bladder entry

2

What are the 2 ways the bladder can obe obstructed

mechanical (stone, stricture, tumor) or junctions (nephrogenic)

3

What factors determine the symptoms seen in urinary tract obstruction? (4)

time course, degree of obstruction, level of obstruction, development of 2ndary complications

4

Anuria is specific fo

bilateral UTO
shock
HUS

5

What does abnormal renal function + widely fluctuating UOP suggest?

bilateral partial obstruction

6

T or F: polyuria excludes obstruction

Flase

7

What is the first test for UTO?

catheterize--> if you put in a catheter and pee comes out, then they were obstructed below the bladder neck

8

After you put in a catheter and there is still no pee what do you do?

ultrasound--> CT (if necessary)

9

What are the hemodynamic effects with acute and chronic UTOs?

Acute: inc RBF with dec GFR and vasodilation

chronic: dec RBF, big dec GFR, vasoconstriction, rennin-also produced

10

What are the differences in tubule effects between acute and chronic UTO?

acute: inc tubule pressure --> inc reabs of Na, urea, and H2O

chronic: loss of concentration ability, decreased transport functions

*basically, acute is still trying to work and chronic gave up a long time ago

11

WIll chronic or acute UTO reposnd to AVP?

acute

12

Will acute or chronic be hyperkalemic and hyperchloremic acidotic?

chronic
