A 
Correct/treat underlying disease if possible (HTN, DM, etc) 
Mostly supportive (prevent HTN, avoid volume overload, avoid nephrotoxins (NSAIDs), treat anemia, renal replacement if needed
41
Q

What is renal replacement therapy (RRT)?

Unilateral sharp colicky pain
Location of stone indicates locations of pain

Supportive care (treat pain and nausea, consider IV fluids)
If recurrent or strong family hx find cause to treat

Kidneys: about 1 in lateral and 1 inch superior to umbilicus (10 and 2 position)
Ureters: none
Bladder: umbilicus
Urethra: superior surface of pubic bone relative positions

66
