Q

Diagnostic studies for urinary/renal

A

*Urinalysis–color, odor, turbidity (cloudiness)
*Urine culture and sensitivity–analysis for number/type of organisms present and antibiotics that will work, must be clean catch
serum creatinine–good indicator of kidney function, normal <1.3, SUPER impt test
*BUN–indicates renal excretion of urea nitrogen
*BUN/creatinine ratio–normal ratio (12:1)=kidney damage. Not normal=dehydration or poor renal perfusion
*Creatinine clearance-24 hour collection, most indicative of kidney damage, NL 70-135 mL/min
*KUB (kidneys, ureters, bladder)–plain film of abdomen, shows shape, size, and position of urinary tract
