  1. Two damaging effects of obstruction are:
    • 1. Stasis of urine = Urine stops;
    • -predisposes to infections & stone formation

    2. Development of backpressure = back flow of urine. interferes with flow, destroys tissues, and predisposes to hydronephrosis (cystic distention caused by urine in renal pelvic area)
  2. Predisposing factors for urinary obstruction
    • 1. Congenital defects in urinary tract structure
    • 2. Pregnancy
    • 3. BPH- enlarged prostate
    • 4. Tumors
    • 5. Kidney Stones
    • 6. Trauma
  3. Clinical manifestations of Obstruction
    • Symptoms depend on the site of obstruction, cause, and how rapidly obstruction occurs.
    • UO is NOT!- because it can be normal or high with obstruction
    • 1. Pain
    • 2. n & v
    • 3. Hypertension
    • 4. Signs and symptoms of UTI- pain on urination, feel like you need to go when you don't
    • 5. Manifestations of renal dysfunction
  4. Diagnosis of Stones
    • -Hx and Sx
    • -Urinalysis
    • -GFR, Cr, BUN
    • - Abdominal x-ray
    • - CT scan, ultrasound, urography,
    • - IVP
  5. Treatment of Obstruction
    • - Less than 5mm stones will usually pass on own.
    • -If stone removal is necessary options = ureteroscopic removal, lithotripsy, open if very large

    - Pain control, antibiotics, increased fluid intake
  6. Prevention of reoccurence of kidney stones:
    • -Fluid intake
    • - Dietary changes
    • - Medications
    • - pH alteration in urine
  7. How does the Renal/Urinary system protect itself from infection?
    • -- Renal parenchyma (tissue) not exposed to bacteria
    • -- Downward flow of urine from kidney via Gravity and peristalsis (waves of involunatry contraction)
    • --Distal valves of ureter: close with urination to prevent backflow
    • -- Sphincters at neck of bladder
    • -- Emptying of bladder
  8. **How do microorganisms invade the urinary system?
    • 1. Up from the urethra
    • 2. From the blood stream
    • 3. From invasive procedures
