  5. Multiples fluid-filled sacs (cysts) within and on the kidney.
    Polycystic kidney disease (PKD)
  6. Inflammation on the lining of the renal pelvis and renal parenchyma.
  7. Cancerous tumor of the kidney in adulthood.
    Renal cell carcinoma (hypernephroma)
  8. Kidney decreases excretion of wastes as a result of impaired filtration function.
    Renal failure
  9. High blood pressure resulting from kidney disease.
    Renal hypertension
  10. Malignant tumor of the kidney occurring in childhood.
    Wilms tumor
  11. Malignant tumor of the urinary bladder.
    Bladder cancer
  12. Antidiuretic hormone is not secreted adequately, or the kidney is resistant to its effect.
    Diabetes insipidus
  13. Insulin is not secreted adequately or not used properly in the body.
    Diabetes mellitus
  14. Measurement of urea levels in blood.
    Blood urea nitrogen (BUN)
  15. Measurement of the rate at which creatinine is cleared from the blood by the kidney.
    Creatinine clearance
  16. X-ray images show multiple cross-sectional and other views of organs and tissues.
    CT Scan
  17. X-ray examinatino (without contrast) of the kidneys, ureters, and bladder.
    Kidneys, ureters, and bladder (KUB)
  18. X-ray examination (with contrast) of the blood vessels of the kidney.
    Renal angiography
  19. X-ray imaging of the renal pelvis and ureters after injection of contrast through a urinary catheter into the ureters from the bladder.
    Retrograde pyelogram (RP)
  20. X-ray record (with contrast) of the urinary bladder and urethra obtained while the patient is voiding.
    Voiding cystourethrogram (VCUG)
  21. Imaging of urinary tract structures using high-frequency sound waves.
  22. Image of the kidney after injection a radioactive substance (radioisotope) into the bloodstream.
    Radioisotope scan
  23. Changing magnetic field produces images of the kidney and surrounding structures in three planes of the body.
    Magnetic resonance imaging (MRI)
  24. Direct visualization of the urethra and urinary bladder with an endoscope (cystoscope).
  25. Process of separating nitrogenous waste materials from the blood.
  26. Use of an artificial kidney machine that receives waste-filled blood from the patient's bloodstream, filters it, and returns the dialyzed blood to the patient's body.
    Hemodialysis (HD)
  27. Use of a peritoneal catheter to introduce fluid into the peritoneal (abdominal) cavity; chemical properties of the fluid cause wastes in the capillaries of the peritoneum to pass out of the bloodstream and into the fluid and then removed by catheter.

  39. hormone secreted by the kidney to stimulate the production of red blood cells by bone marrow
    erythropoietin (EPO)
  40. process whereby some substances, but not all, pass through a filter (kidney=glomerulus)
