Medical Terminology Simplified

Increased formation and secretion of urine

Kidney disease that has advanced to the point that the kidneys can no longer ade-

quately filter the blood and, ultimately, requires dialysis or renal transplantation for

survival; also called chronic renal failure(CRF) (See Fig. 7–9.)

Common diseases leading to ESRD include malignant hypertension, infections, diabetes

mellitus, and glomerulonephritis. Diabetes is the most common cause of kidney trans-

plantation.

Involuntary discharge of urine after the age at which bladder control should be estab-

lished; also called bed-wetting at nightor nocturnal enuresis

In children, voluntary control of urination is usually present by age 5.
