calyx; calyces Cup-shaped collecting region in the renal pelvis (central section of the kidney).
catheter Tube for injecting or removing fluids.
cortex Outer region of an organ; renal cortex is the outer region of the kidney.

glomerular Pertaining to a glomerulus.
glomerulonephritis Inflammation of glomeruli in the kidney.
glomerulus; glomeruli Tiny ball of capillaries (microscopic blood vessels) in the cortex of the kidney. As blood flows through each glomerulus, waste materials and other substances are filtered from the bloodstream.
glycosuria Sugar in the urine.
hematuria Blood in the urine.
hemodialysis Removal of wastes materials from the blood in patients whose kidneys have stopped functioning. Blood leaves the body and circulates through a machine that removes wastes before sending the blood back into the body through a vein.
hilum Depression or hollow in the surface of an organ, such as the kidney and lung. It is the area where blood vessels and nerves enter and leave the organ.
hydronephrosis Abnormal condition of excess backup of fluid (urine) in the kidney.
interstitial nephritis Inflammation of the tissue in the kidney that lies between (interstitium) the nephrons (functional units).
ketonuria Presence of ketones in the urine. Common in uncontrolled diabetes mellitus, but can occur in any time the body begins to bread down fatty tissue to provide energy as in starvation.
ketosis Accumulation of large quantities of ketone bodies (acetones) in the blood; ketoacidosis.
kidney One of two bean-shaped organs behind the abdominal cavity on either side of the backbone in the lumbar region.
lithotripsy Process of using high-energy sound waves to crush a stone within the kidney or ureter.
meatal stenosis Narrowing of the meatus (opening) leading from the urethra to the outside of the body.
meatotomy Incision of a meatus in order to enlarge it. The urinary meatus is the opening of the urethra to the outside of the body.
meatus An opening or passageway. The urinary meatus is the opening of the urethra to the outside of the body and the auditory meatus is the opening of the ear to the outside of the body.
medulla Inner region of an organ.
medullary Pertaining to the medulla or an organ.
micturition Urination; voiding.
nephrolithiasis Abnormal condition of kidney stones.
nephrolithotomy Incision of the kidney to remove a stone.
nephron Functional unit of the kidney, consisting of a glomerulus, renal tubule, and collecting tubule.
nephropathy Disease or abnormality of the kidney.
nephroptosis Prolapse of a kidney; floating or wandering kidney.
nephrosclerosis Hardening of arteries and arterioles in the kidney.
nephrostomy Opening of the kidney to the outside of the body.
nephrotic syndrome Group of symptoms that occur due to loss of protein in the urine. Symptoms include edema (swelling of tissues), hypoalbuminemia loss of protein from the blood), proteinuria, and susceptibility to infection. This condition is also known as nephrosis.
nitrogenous waste Substance containing nitrogen and excreted in urine; examples are urea, creatinine, and uric acid.
nocturia Urinary frequency at night.
oliguria Scanty urination.
paranephric Pertaining to beside or near kidney.
peritoneal dialysis Separation of nitrogenous wastes from the bloodstream by introducing fluid into the peritoneal cavity. Wastes then leave the bloodstream and enter the fluid, which is drained through an abdominal catheter.
perivesical Pertaining to surrounding the urinary bladder.
phenylketonuria Excess of phenylketones in the urine; diagnosed by a PKU test at birth.
polycystic kidney disease Kidneys are filled with cysts that prevent normal kidney function.
polydipsia Excessive thirst.
polyuria Excessive urination.
potassium Chemical element that forms salts with other minerals such as calcium and is vital for bodily processes. When dissolved in water, it is an electrolyte whose balance is regulated by the kidney.
pyelogram X-ray record of the kidney (renal pelvis) after injection of contrast material.
pyelolithotomy Incision to remove a stone from the renal pelvis of the kidney.
