Renal Conditions Flashcards
etiology of pyelo
ascending infection or bloodstream infection
risk factors for pyelo
–pregnancy
–recurrent lower UTIs
–antibiotic resistant strain
what is pyelonephritis?
inflammation of the kidneys
what organism often causes pyelo?
e. coli
what can pyelo cause?
CKD or sepsis
patho of pyelo
inflammatory response –> kidney tissue damage
what can develop from pyelo?
abscesses and necrosis
symptoms of pyelo
–sudden onset of: fever, chills, CVA tenderness
–lower UTI symptoms
–hematuria may occur
–N/V
–anorexia
treatment of pyelo
antibiotics: trimethoprim/sulfamethoxazole (Bactrim), ciprofloxacin/nitrofurantoin (Macrobid)
who can’t Bactrim be prescribed to?
pregnant women
complications of pyelo
urosepsis
specifics of urosepsis
–more likely in elderly
–severe systemic response
–high mortality rates
treatment of severe pyelo
–IV antibiotics
–urinalysis
–urine culture
urinary obstruction locations
–renal pelvis
–ureter
–bladder or pelvis
what causes obstruction in the renal pelvis?
renal calculi
what causes obstruction in ureters?
–renal calculi
–pregnancy
–tumor
what causes obstruction in the bladder and urethra?
–bladder cancer
–neurogenic bladder
–prostatic hyperplasia
–prostate cancer
–urethral strictures
complications of obstruction
–stasis of urine flow
–backup pressure
where does backup pressure affect?
–hydroureter
–hydronephrosis
–postrenal acute kidney injury
potential complication of stasis of urine flow
infection when urine can’t flow freely
manifestations of acute obstruction
–depends on the: site, cause, speed of onset
which manifestation of acute obstruction primarily determines severity of pain?
speed of onset
nephrolithiasis
–renal calculi (kidney stones)
–clumps of crystals in urinary tract
–small as grain of sand to large as a golf ball
–may be smooth or jagged
–most common causes of renal obstruction
patho of nephrolithiasis
–urine is a solution of solvent and solutes
–problem = super-saturation with a solute
–crystals begin forming in the nephron
what is urinary crystal formation enhanced by?
–pH changes (UTI)
–excessive concentration of insoluble salts in the urine (dehydration, bone disease, gout, renal disease)
–urinary stasis (immobility/sedentary lifestyle)
risk factors for nephrolithiasis
–men
–20s-30s
–white
–family history
–congenital defect
–hot weather (dehydration)
–obesity
most common type of kidney stone
calcium oxalate or calcium phosphate
risk factors for calcium oxalate/calcium phosphate
–family history
–idiopathic
–increased calcemia
–increased oxaluria
risk factors for struvite (staghorn) stones
UTIs
risk factors for uric acid stones
gout
types of kidney stones
–calcium oxalate/calcium phosphate
–struvite
–uric acid
causes of calcium oxalate stones
–dehydration
–low urine output
–high sodium intake
–high oxalate intake
–high protein intake
symptoms of renal colic
–flank pain
–radiation to lower abdomen and groin
–colicky spasms (lasting 20-60 minutes)
–intermittent spasms
–sharp pain from ureter scraping ureter wall
accompanying symptoms of nephrolithiasis
–N/V
–dysuria
–chills, fever (only if infection)
–hematuria
–foul smelling urine
–diaphoresis
pharm for nephrolithiasis (acute pain)
–morphine or NSAIDs
–IV fluids
preventative pharm for nephrolithiasis
–calcium = thiazide diuretics
–struvite = antibiotics
–urate = allopurinol
