  1. Inflammation of the renal pelvis and medullary tissue
  2. What are some factors that contribute to the development of pyelonephritis
    • pregnancy
    • catheter
    • cytoscope
  3. Describe the patho of pyelonephritis
    • one or both kidneys involved
    • tubules affected, not glomeruli
    • purulent exudate fills renal pelvis, calyces, & medulla get inflammed
    • necrosis & absecces may extend to cortex & capsule
    • exudate may block urine flow
  4. What are the signs of pyelonephritis
    • pyuria-lots of pus absecces rupture
    • bacteruria, hematuria, & proteinuria
    • WBC cast
    • fever & chills
    • flank or lower back pain-from capsule stretching
    • frequent & dysuria
  5. What are casts
    molds of the tubules
  6. How are casts formed
    • WBC migrate to tubules due to inflammation
    • endothelial cells releases gel substance
    • coats WBC
  7. What would a cast indicate
    there is a problem higher up in the urinary tract
  8. would you see a cast with cystitis
  9. What are the diagnostic test for pyelonephritis
    • H&P-abdominal or lumbar pain during palpitation
    • Urinalysis-C&S-protein,blood, pus,& bacteria
    • WBC casts
    • X-ray-hydronephrosis(enlarged kidneys)
  10. What are the complications of pyelonephritis
    • severe infections
    • abseccess
    • acute renal failure-exudate obstruct urine flow
  11. What is the treatment for pyelonephritis
    • Antibiotics
    • Increase fluid
    • surgery for obstructions
    • hospitalization
  12. What is the prognosis for pyelonephritis
    • good if treated quickly
    • chronic pyelonephritis-fibrious scars-loss of tubule function
    • chronic renal failure
  13. What is the onset of pyelonephritis
