Renal Exam 2 Flashcards
Pyelonephritis
Upper UTI or Kidney Infection
Pyelonephritis is
Inflammation of one or both kidneys
Pyelonephritis Etology
Start as lower uti and goes up the tract. E Coli is most common pathogen
Pyelonephritis risk factors
Pregnancy
Recurrent lower utis
Antibiotic resistant strain
Pyelonephritis can lead to
permanent kidney damage with abscess and necrosis
Pyelonephritis: Clinical Manifestations
Sudden onset:
-Fever
-Chills
-CVA tenderness
Systemic infection = fevers and chills vs those with lower UTI
Hematuria may occur
Pyelonephritis: Treatment
Antibiotics
Bactrim - Ciprofloxacin - Nitrofurantoin
Review bactrim and ciprofloxacin for exam
Pyelonephritis complications
Urosepsis most likely in elderly and pregnant
Where can you have a urinary obstruction
Anywhere along the tract
-Renal pelvis
-Ureter
-Bladder or pelvis
Common Renal Obstruction: Renal Pelvis
Renal calculi
Common Renal Obstruction: Ureter
Renal calculi
Pregnancy
Tumors
Common Renal Obstruction: Bladder and Urethra
Bladder cancer
Neurogenic bladder
Prostatic hyperplasia
Prostate cancer
Urethral strictures
Kidney stones not as common
Complications of Obstruciton
Stasis of urine flow. Infections is much likely
Back up pressure
-Hydroureter
-Hydronephrosis
-Post Renal acute kidney injury
Hydronphrosis
Back of fluid into kidney
Surgical intervention
Hydroureter
Back of fluid in the ureter
Acute Obstruction: Clinical Manifestations
Depends on site
Obstruction in renal pelvis does not cause as much pain or difficulty urinating because there is room for the stone there.
Once the stone leave renal area and into the ureter the place is much small and the pain is going to be very severe
Pain comes in waves as the ureter tries to move the stone out
Nephrolithiasis
Renal calculi or kidney stones
Clumps of crystals in the urinary tract
Can be small or the size of gold ball
Nephrolithiasis: Pathogenesis
Urine is a solution of solvent (water) and solutes (particles)
Super saturation with a solute and crystals begin forming in the nephron of the kidney
Crystal Formation is enhanced by
Ph changes: UTI
Excessive concentration of insoluble salts in the urine. (Dehydration - Bone disease - Gout - Renal disease)
Urinary stasis - Immobility/sedentary lifestyle
Nephrolithiasis: Risk Factors
-Men
-Age 20-30’s
-White
-Family history
-Congenital defect (long urine in system)
-Weather? Hot weather = dehydration
-Obesity
Types of kidney stones
Calcium oxalate or calcium phosphate
Struvite (staghorn)
Uric acid
Types of stones: Calcium oxalate / calcium phosphate RF’s
Family history
Idiopathic
Diet
Increase Calcemia
Increase Oxaluria
Types of stones: Struvite Staghorn
Risk factor = UTI
Types of stones: Uric Acid
Risk factor = Gout
Nephrolithiasis: Clinical Manifestations
Renal Colic: Pain in the flank area that radiates from lower abd and groin. Spazzy. Sharp from stone scraping
Accompanying symptoms of neprholithiasis
NV
Dysuria
Chills and fever with infection
Hematuria
Foul smelling urine
Diaphoresis
Nephrolithiasis: Pharmacotherapy
Morphine or NSAIDS
IV fluids
Preventive Med for Calcium Stones
thiazide diuretics
Preventive meds for struite stones
antibiotics
Preventive meds for urate stones
allopurinol
Urologic Cancers
Kidney cancer
Bladder cancer
Urologic Cancer: Kidney
Renal cell carcinoma 85% of kidney cancers
Kidney cancer: Risk factors
Smoking #1
Obesity
Age - Older
Male - Men
Genetics
Renal Cell Carcinoma: Clinical Manifestations
-No early manifestations
Late manifestations: CVA tenderness - Hematuria - Possible palpable abdominal mass
Metastasis of Renal Cell Carcinoma
Occurs to the bone or lungs
Renal cell carcinoma is often
Resistant to chemo so you have to have surgery
Bladder Cancer
-Urotherlial carcinoma (>90)
Bladder Cancer: Risk facotrs
Smoking #1
Male
Occupations with exposure to toxin RUBBER OR PAINT TOXINS
Low fluid intake toxins sit in the bladder
Bladder Cancer: Clinical Manifestations and Treatment
Early and Late
Early = Hematuria
Later:
-Frequency
-Urgency
-Dysuria
Bladder cancer: Treatment
Stage 1 = Intravesical chemo
Advanced stage = systemic chemo
Glomerular Disease
Glomerulonephritis
Nephrotic Syndrome
Glomerulonephritis
A variety of conditions that cause inflammation of the glomeruli
Primarily and IMMUNE process
Glomerulitis: Where does the damage occur
In the glomerulus: Delicate network of arterioles within the bowman’s capsule
In the tubules: Massive consumers of oxygen
The Glomerulus: 3 Capillary membranes
- Endothelium
- Basement membrane (a lot of issues occur here)
- Podocytes (special epithelia cells) (start of urine)
Type II Hypersensitivity Reaction
Reactions occur on the cell surface and results in direct cell death or malfunction
Direct cell death
Type III Hypersenstivity reaction
Immune complexes are deposited into tissues and the resulting inflammation destroys the tissues
Inflammation destroys the tissues by becoming deposited and becoming inflamed
Glomerulonephritis: Etiology 2 types of injury
- Antibodies attach to antigens of the glomerular basement membrane (Anti-GBM antibodies) - 5% = Type II reaction
- Antibodies react with circulating antigens and are deposited as immune complexes in the GBM - 90% = Type III reaction
Acute Glomerulonephritis: Onset and Symptoms
-Abrupt HARP
-Hematuria
-Azotemia (to much waste in blood)
-Retention (sodium and water) (Edema and In BP)
-Proteinuria
Acute Glomerulonephritis Triggers
Post infections
Primary Disease
Multisystem Disease
Acute Glomerulonephritis Triggers: Post infections
-Postreptococcal infections
-Nonstreptococcal infection (bacterial viral parasitic)
Acute Glomerulonephritis Triggers: Primary disease
Berger disease
Antibodi IGA builds up in the kidney
Acute Glomerulonephritis Triggers: Multisystem Disease
-Goodpasture’s syndrome, systemic lupus erythematosus (SLE), vasculitis
These can attack the kidneys
Anti-GBM Antibodies
These are similar to the ones the lungs so patients typically have respiratory problems and cough up blood
Goodpasture syndrome
Acute Glomerulonephritis: Pathogenesis
- Trigger
- Immune complexes form
- Complement activated
- Release of mediators
- Tissue injury
- HARP
Chronic Glomerulonephritis
-Long term inflammation = scar tissue
Scar tissues can not filter correctly and as the build up scar tissue occurs the kidneys are able to maintain less
Nephrotic Syndrome
The glomerulus is too permeable to plasma proteins
Eliminations of 3 grams of protein per day
Nephrotic Syndrome: Etiology
-Glomerulonephritis
-Diabetes mellitus
Nephrotic Syndrome: Pathogenesis
Increased glomerular permeability
Proteinuria
Hypoalbuminemia (start to 3rd space)
Nephrotic Syndrome: Clinical Manifestations
-Edema
-Hyper tension
Liver problems:
-Hyperlipidemia
-Hypercoagulation
-Loss of antithrombin and plasminogen
Glomerulopathy: Diabetes and HTN complications
DM:
-Major complications
-Gross thickening of the GBM
-Ultimately leading to –> ESRD
HTN:
-Decrease renal perfusion –> sclerotic glomerular changes
Glomerulopathy: Manifestations
Hematuria
Oliguria
Fluid retention
Increase BUN/Cr ratios
Proteinuria
Low albumin (hypoproteinemia)
