Renal Flashcards
Inflammation of renal parenchyma and collecting system
hint: upper tract

Pyelonephritis
Inflammation of bladder
Hint: upper tract
Cystitis
Inflammation of urethra
Hint: lower tract
Urethritis
UTI that is spread systemically
Urosepsis
UTI risk factors
Congenital defects, fistula, obesity, short female urethra, age, diabetes, hiv, obstruction, renal impairment, urinary retention, catheter, constipation, void delay/dysfuntion, sex, poor hygiene, bubble bath
Dysuria, hematuria, hesitancy, intermittent, dribble, nocturia, increased frequency
Lower UTI
Fever, chills, flank pain, dysuria, nocturia, hematuria, hesitancy, urgency, increased frequency
Upper UTI
UTI dipstick urinalysis
Nitrites, WBCs, and leukocyte esterase present
How to confirm UTI
Microscopic urinalysis
Other UTI test
Urine culture, ct or ultrasound
UTI meds
Abx, fluconazole (fungal), monurol, macrodatin/macrobid, bactrim, cephalexin
UTI goals
Relief of symptoms, no upper tract involvement, no recurrence
UTI management
Adequate fluid intake, empty bowel and bladder regularly/efficently
CAUTI Precautions
Avoid unnecessary catheters, promote early removal, aseptic technique
Calcium stones in urinary tract
Renal calculi
Formation of kidney stones
Nephrolithiasis
Formation of stones in urinary tract
Urolithiasis
Warm climate, tea, salt, protein (uric acid, decreased fluid, increased calcium, obesity, sedentary
Renal calculi risks
Autosomal recessive disorder that increases urinary cystine excretion
Cystinuria
Types of stones
Calcium, cystine, struvite, uric acid
Sudden severe sharp pain in flank, back or lower abdomen
Renal colic
Renal colic, mild shock, cool moist skin, dysuria, fever, chills
Renal calculi symptoms
Urine pH increased w/ calculi
Struvite
Urine pH decreased w/ calculi
Uric acid or cystine
Non contrast ct or ultrasound, urine pH (increased or decreased), urinalysis (hematuria/crystalluria +)
Urinary Tract Calculi tests
Opioids, NSAIDs, ą-adrenergic blocker (flomax), chronic ABx
Renal calculi meds
Lithotripsy or nephrolithotomy
Renal calculi surgical tx
Increase hydration, restrict sodium, limit cola/coffee/tea, decrease calcium, oxalate and purine
Renal calculi management
Dairy, cocoa, lentils, fish
Calcium diet
Dark greens (spinach), red veggies, citrus, caffeine
Oxalate diet
Small bone fish, scallops, organ meat, pork, beef, mutton
Purine diet
Reversible rapid loss of kidney function w/ or w/o decreased urine output
Acute kidney injury
Decreased systemic circulation > decrease blood flow > decreased glomerular filtration and perfusion
Pre Renal AKI
Problems that cause direct kidney tissue damage > impaired nephron function
Intra Renal AKI
Mechanical obstruction to outflow of urine
Post Renal AKI
Decrease cardiac output, decrease vascular resistance, decrease renal vascular blood flow, hypovolemia
Pre renal risk factors
Acute tubular necrosis, interstitial nephritis (med allergy or infection), nephrotox injury
Intra renal risk factors
BPH/prostate/bladder cancer, calculi, neuromuscular disorder, spinal cord disease, stricture, trauma
Post renal risk factors
Urine output < 400 mL/day
Oliguria
Oliguria, hyPOvolemia, metabolic acidosis, hyPOnatremia, hyPERkalemia, leukocytosis, increased BUN and creatinine, seizures>stupor>coma, anuria
AKI symptoms
Acute reduction in urine output AND/OR increased creatinine, CT scan, renal scan, urinalysis (casts, WBCs, RBCs +), electrolytes (low Na+ and high K+)
AKI testing
Dialysis, calcium supplements, diuretics, RRT, IV Insulin, Sodium Bicarbonate
AKI treatment
Adequate protein, restrict phosphate and sodium, lower potassium, fluid restriction
AKI management
Progressive irreversible loss of kidney function
Chronic Kidney Disease
DIABETES, HTN, age, diabetic neuropathy, CVD, fam Hx, nephrotox meds, glomerulonephritis, cystic and urologic diseases, black/native American
CKD risk factors
Decreased kidney function that may develop symptoms in multiple systems
Uremia
Uremia, increase BUN and creatinine, hyPERkalemia, hypERglycemia, hyERinsulemia, increase triglycerides, dilutional hyPOnatremia, uremic fetor, hyPERmag, metabolic acidosis, anemia, increased CO2, peripheral neuropathy
CKD symptoms
Piss breath
Uremic fetor
GFR <60mL/min for 3 months AND/OR kidney damage > 3 months, hemoglobin and hematocrit, increased BUN and Creatinine, biopsy, scans
CKD testing
Preserve existing kidney function, reduced CVD risk, prevent complications, promote comfort
CKD goals
IV insulin/glucose (hyPERkalemia), ACE inhibitors (HTN), Vitamin D, RRT, erythropoietin (anemia), diuretics
CKD meds
Peritoneal dialysis, hemodialysis, kidney transplant
CKD procedures
Weight loss, limit alcohol, stop smoking, DASH diet, restrict protein, oral health, sodium/phosphate/potassium restriction, avoid NSAIDS and magnesium based laxatives and antacids
CKD Management
Exit site infection, peritonitis, hernias, lower back pain, bleeding, atelectasis, pneumonia, bronchitis
Peritoneal dialysis complications
Abdominal pain and rebound tenderness
Peritonitis
Exit site infection and peritonitis treatment
Abx
HyPOtension, muscle cramps, blood loss, hepatitis B
Hemodialysis complications
