Upper UTI Management
- Trimethoprim/Sulfa (Bactrim)
- Cipro
- Quinolones
- Aminoglycoside (gent)
- 14 days to 6 months

3 startegies for Chronic Renal failure Management
- Control HTN and DM
- Reducing dietary protein to 40g/day
- Modify drug dosing
Causes pre-renal failure
- Shock
- Dehydration
- Burns
- Sepsis
Most common cause of Intra-renal failure
Nephrotoxic agents
Three causes of intra-renal failure
- Hypersenstivity reactions
- Obstruction of vessels
- Mismatched blood products
Location of acute tubular necrosis
Tubular portion of the nephron
Most common cause of intrarenal failure
Examples of mechanical post-renal failure
Calculi
Tumors
Urethral stricture
BPH
Causes of Functional Postrenal Failure
Neurogenic bladder
Diabetic neuropathy
Specific gravity for intra-renal and post-renal disease
<1.015
Urine sodium in intra and post renal disease
>40
Sediment in intra-renal disease
Granular/casts
FENa in intra and post renal disease
>3
Serum BUN/Creat ratio in Pre-renal dz
>10:1
Pre-renal Managment
Expand volume
Consider dopamine
Intra-renal
- Maintain renal perfusion
- D/c nephrotoxic drugs
- HD as needed
Post-renal managment
- Remove source of obstruction
- Check foley
- CT
- Renal US
Name percentage of population that will develop renal cacluli
10%
Name four types of stones
Calium
Uric acid
Struvite
Cystine
Which stones result from UTI’s with urease producing bacteria?
Struvite
What does radiation of pain to the groin indicate in renal calculi?
Passage of stone to the lower 1/3 of ureter
Testicular pain is possible
Diagnostics for renal calculi
Abd XR- majority of stones are radiopaque
CT is indicated
Crystals in urinary sediment is suggestive of calculi
