URINARY TRACT OBSTRUCTION
explanation
etiology
s/s
dx test
- Blockage that inhibits flow of urine through normal pathway
- Etiology - urolithiasis; BPH; tumor
- s/s - fever; n/v; flank pain; difficulty starting stream; limited urine; hydronephrosis
- Blunt percussion to the kidney causing pain indicates hydronephrosis
RENAL CALCULI
explanation
etiology & types
r/f
s/s
complication
- Urolithiasis - usually made of calcium or uric acid (also struvite, crystalline) - form inside kidney & can travel through UT
- Etiology - varies on type
- Struvite - infection
- Uric acid - gout
- r/f - dietary; infection; ↑ uric acid; genetics
- s/s - hydronephrosis; unilateral flank pain; n/v; retching with waves of pain; dysuria; hematuria; frequency with small voids; hesitancy
- More painful & complicated if stone gets stuck in ureter
CYSTITIS
etiology
r/f
s/s
- “UTI” or “bladder infection”
- Etiology - usually E. coli
- r/f - aging (loss of estrogen, skin changes around vulva); young girls; female; Foley; incontinence; sexual activity
- s/s - dysuria; frequency; hematuria; cloudy urine; malodorous urine; confusion in older pts
PYELONEPHRITIS
etiology
r/f
s/s
- “Kidney infection”
- Etiology - often ascends from bladder; usually E. coli
- r/f - frequent UTI; reflux; catheter use; enlarged prostate; CKD; kidney stones; DM; immunocompromise
- s/s - systemic - fever; n/v; malaise; colicky flank pain, waves of nausea; chills; dysuria (burning with urination); malodorous urine; hematuria; urgency; frequency; pyuria
STRESS INCONTINENCE
explanation
etiology
r/f
s/s
- Physical activity puts pressure on bladder
- Etiology - sphincter & pelvic muscles are stretched out and weak
- r/f - pregnancy; childbirth; obesity
- s/s - loss of urine with standing up, laughing, coughing, sneezing, lifting, sex, exercise
OVERFLOW INCONTINENCE
explanation
etiology
r/f
s/s
- Overfull bladder
- Etiology - nerve damage affecting ability to sense fullness; blockage in urinary tract; weak detrusor muscle; medications
- r/f - enlarged prostate; kidney stones; neurological damage; tumors; DM; MS; trauma
- s/s - leaking urine without sensation of fullness__, with full bladder
URINARY RETENTION
explanation
etiology
r/f
s/s
- Inability to completely empty bladder
- Etiology - nerve damage affecting ability to sense fullness; blockage in urinary tract; weak detrusor muscle
- r/f - recent surgery, especially to bladder; neurological damage; blockage; structural
- s/s - inability to empty bladder despite fullness
NEPHROTIC SYNDROME
explanation
etiology
r/f
s/s
- Too much protein excretion
- Etiology - damage to basement membrane - ↑ permeability of capillary wall
- r/f - infection; CKD; DM; lupus; medications
- s/s - proteinuria; edema; foamy urine; wt gain, ascites, puffy face (fluid leaving vascular compartment); fatigue; loss of appetite; hypoalbuminemia; HLD (liver’s response to hypoalbuminemia); ↓ antithrombin 3 (hypercoagulative state)
GLOMERULONEPHRITIS - NEPHRITIC SYNDROME
explanation
etiology
r/f
s/s
- Inflammation of glomerulus; Damage to basement membrane - larger molecules (RBCs, WBCs) able to enter filtrate
- Etiology - autoimmune, type 3 hypersensitivity - complexes get stuck in glomerulus & cause damage
- r/f - infection; immune disease; vasculitis; DM; HTN
- s/s - severe hematuria (cola colored)__; pyuria__; proteinuria; edema; HTN; oliguria
3 types of acute kidney injury
- Prerenal - blood flow to kidney
- Intrarenal - within kidney
- Postrenal - ureters, bladder, urethra
PRERENAL AKI
etiology
r/f
s/s
- Sudden renal hypoperfusion
- r/f - hemorrhage/blood loss__; HF; sepsis; severe dehydration; severe burns; pancreatitis; hepatitis; blood loss in surgery, injury
- s/s - hypovolemia; thirst; ↓ urine; dizziness; ortho hypotension; v/d; hemorrhage
INTRARENAL AKI
etiology
r/f
s/s
- Sudden episode of kidney failure due to direct glomerular damage
- r/f - infection; chronic disease (GN, nephrotic syndrome); toxins; medications
- s/s - vary - fever; rash; hematuria; oliguria; fatigue; dyspnea; nausea
POSTRENAL AKI
etiology
- Sudden episode of kidney failure - blockage below kidneys causes waste to back up
- Etiology - varies - tumor; enlarged prostate; stone
9th leading cause of death in US
CKD
gradual, progressive loss of kidney function
chronic kidney disease/renal failure
stages of renal failure with % kidney function
- 1 - 90% or more function
- 2 - 60-89%
- 3 - 30-59%
- 4 - 15-29%
- 5 - <15% - end stage renal failure
etiology of CKD
increasing amount of glomerular damage, leading to kidneys’ inability to manage filtration
- Acute bil kidney diseases
- Severe, prolonged circulatory shock/HF
- Nephrotoxins
- Mechanical obstruction
