Renal or urinary diseases can interfere with the function of the kidneys and other urinary system components. Urinary tract infections can cause inflammation or damage to any part of the urinary system, requiring antibiotics to treat. Renal disease, a far more serious condition, can cause renal failure, requiring dialysis to pick up the slack of the failing kidneys. Sometimes a kidney transplant is necessary to get the blood filtered properly again without the outside help of dialysis.
