Dysuria
|
- Painful urination
- Commonly associated with bacterial infections - Other causes include other sources of inflammation, including neoplasms |
|
Hematuria
|
- Blood in urine
- May be Macroscopic or Microscopic - If pain also present, then often due to infection or a stone passing in the ureter - If no pain, blood may be due to a kidney or bladder tumor, renal cyst, or prostatic device - Glomerulonephritis is indicated by the presence of RBC CASTS in the URINE! |
|
If you see RBC CASTS in the urine, what condition are you dealing with?
|
Glomerulonephritis
|
|
Pyuria
|
- WBC's in the urine
- Prominent in UTIs, but may also be a nonspecific sign of inflammation... - WBC CASTS in urine indicate nephritis, which may or may not be infectious |
|
WBC Casts in the urine indicate what condition?
|
Nephritis
|
|
Oliguria
|
- Reduction of urine output to less than 500 ml/day
- could be because of prerenal factors (dehydration, bilateral renal artery occlusion), renal factors (acute renal failure), or postrenal factors (bladder outlet obstruction) |
|
Anuria
|
- abscence or severe reduction of urine output, generally less than 100 ml/day
- could be because of prerenal factors (dehydration, bilateral renal artery occlusion), renal factors (acute renal failure), or postrenal factors (bladder outlet obstruction) |
|
Azotemia
|
- Accumulation of excess nitrogenous wastes in the blood in the form of urea, creatine, ammonia, or uric acid
- Often a sign of kidney failure but may also be the result of increased protein digestion (i.e. during a gastrointestinal bleed) or increased protein catabolism (ie severe burns) - Uremia is often used as a synonym, but uremic syndrome is a separate clinical entity. |
|
Cystitis
|
- Bladder infection
- Usually E. coli - Frequency, urgency, dysuria |
|
Bladder carcinoma: Risk factors
|
- Smoking
- Schistosomiasis - Aniline dyes |
|
Renal Artery stenosis
|
- Cause of secondary hypertension
- Fibromuscular dysplasia (young women) - Atherosclerosis (older patients) |
|
Glomerulonephritis
|
- Hematuria
- Proteinuria - RBC casts - Causes - Poststreptococcal, Goodpasture's syndrome,Diabetic glomerulosclerosis (a chronic form of this disease), Lupus (a chronic form of this disease) |
|
Diabetic glomerulosclerosis
|
- Chronic Glomerulonephritis in which proteinuria gradually progresses to renal failure and uremia
|
|
Nephrotic syndrome
|
- Proteinuria
- Edema - Hypoalbuminemia - Minimal Change disease is the most common in children and Diabetis is the most common in adults |
|
Acute Tubular Necrosis
|
- Due to ischemia or toxins - damage to the renal tubules from bad blood or lack of blood...
- Resolves in several weeks - May need dialysis |
|
Uremic Syndrome
|
- Symptomatic Renal failure is called this ...is not usually symptomatic until GFR is below 20 ml/min
- CNS changes - Asterixis (flapping tremor) - Pericarditis - Nausea and Vomiting - Yellow-brown skin |
|
Polycystic Kidney Disease
|
- Autosomal dominant
- Usually asymptomatic until adulthood when it gradually progresses to end-stage renal disease - Hematuria - Hypertension - leads to intracranial Hemorrages - Urinary tract infections (UTIs) - 15% of patients with this disease will have subarachnoid hemorrages |
|
Alport's Syndrome (Hereditary Nephritis)
|
- X-linked disorder related to type IV collagen that affects the glomerular basement membrane
- Deafness and Renal Failure - in males during early adulthood |
|
Hyperkalemia
|
- >5.5 mEQ/L
- Muscular weakness - Cardiac arrhythmias |
