A
acute (uh-KYOOT):
Acute often means urgent. An acute disease happens suddenly.
It lasts a short time. Acute is the opposite of chronic,
or long lasting.
acute renal (REE-nul) failure:
Sudden and temporary loss of kidney function.
(See also chronic kidney disease.)
acute tubular (TOO-byoo-lur) necrosis (neh-KRO-sis)
(ATN):
A severe form of acute renal failure that develops
in people with severe illnesses like infections or with low blood
pressure. Patients may need dialysis. Kidney
function often improves if the underlying disease is successfully
treated.
albuminuria (AL-byoo-mih-NOO-ree-uh):
More than normal amounts of a protein called albumin in the urine.
Albuminuria may be a sign of kidney disease.
allograft (AL-oh-graft):
An organ or tissue transplant from one human to
another.
Alport syndrome (AL-port SIN-drome):
An inherited condition that results in kidney
disease. It generally develops during early childhood and is more
serious in boys than in girls. The condition can lead to end-stage
renal disease, as well as hearing and vision problems.
The common symptoms of this condition are chronic
blood and protein in the urine.
amyloidosis (AM-ih-loy-DOH-sis):
A condition in which a protein-like material builds up
in one or more organs. This material cannot be broken down and
interferes with the normal function of that organ. In kidneys,
amyloidosis can lead to proteinuria, nephrotic
syndrome, and kidney failure.
analgesic (AN-ul-JEE-zik)-associated kidney disease:
Loss of kidney function that results from long-term
use of analgesic (pain-relieving) medications. Analgesics that
combine aspirin and acetaminophen are most dangerous to the kidneys.
anemia (uh-NEE-mee-uh):
The condition of having too few red blood cells. Healthy red
blood cells carry oxygen throughout the body. If the blood is
low on red blood cells, the body does not get enough oxygen. People
with anemia may be tired and pale and may feel their heartbeat
change. Anemia is common in people with chronic kidney disease
or those on dialysis. (See also erythropoietin.)
antidiuretic (AN-tee-DY-uh-RET-ik) hormone (ADH):
A natural body chemical that slows down the urine
flow. Some children who wet their beds regularly may lack normal
amounts of antidiuretic hormone.
anuria (uh-NYOOR-ee-uh):
A condition in which the person stops making urine.
arteriovenous (ar-TEER-ee-oh-VEE-nus) (AV) fistula
(FIST-yoo-luh):
Surgical connection of an artery directly to a vein, usually
in the forearm, created in patients who will need hemodialysis
(see dialysis). The AV fistula causes the vein to
grow thicker, allowing the repeated needle insertions required
for hemodialysis.
Arteriovenous Fistula
autoimmune (AW-toh-ih-MYOON) disease:
Any disorder in which the body is attacked by its own immune
system. Examples are Goodpasture syndrome
and lupus erythematosus (see lupus nephritis).

B
biopsy (BY-op-see):
A procedure in which a tiny piece of a body part, such as the
kidney or bladder, is removed for
examination under a microscope.
bladder (BLAD-ur):
The balloon-shaped organ inside the pelvis that
holds urine.
blood urea (yoo-REE-uh) nitrogen (NY-truh-jen) (BUN):
A waste product in the blood that comes from the breakdown of
food protein. The kidneys filter blood to remove
urea. As kidney function decreases, the BUN level increases.
[Top]
C
calcium (KAL-see-um):
A mineral that the body needs for strong bones and teeth. Calcium
may form stones in the kidney.
chronic (KRAH-nik):
Lasting a long time. Chronic diseases develop slowly. chronic
kidney disease may develop over many years and lead to
end-stage renal disease.
chronic kidney disease (CKD):
Any condition that causes reduced kidney function over a period
of time. CKD is present when a patient's glomerular filtration
rate remains below 60 mL/min/1.73 m2 for more
than 3 months.
congenital (kun-JEN-ih-tul) nephrotic (nef-RAH-tik)
syndrome:
A genetic kidney disease that develops before birth
or in the first few months of life. Congenital nephrotic syndrome
usually leads to end-stage renal disease and the
need for dialysis or a kidney transplant
by the second or third year of life.
creatinine (kree-AT-ih-nin):
A waste product from meat protein in the diet and from the muscles
of the body. Creatinine is removed from blood by the kidneys;
as kidney disease progresses, the level of creatinine in the blood
increases.
creatinine clearance:
A test that measures how efficiently the kidneys
remove creatinine and other wastes from the blood.
Low creatinine clearance indicates impaired kidney function.
cyst (SIST):
An abnormal sac containing gas, fluid, or a semisolid material.
Cysts may form in kidneys or in other parts of the
body. (See also renal cysts.)
cystine (SIS-teen):
An amino acid found in blood and urine. Amino acids are building
blocks of protein. (See also cystine stone and cystinuria.)
cystine stone:
A rare form of kidney stone consisting of the amino
acid cystine.
cystinuria (SIS-tih-NOO-ree-uh):
A condition in which urine contains high levels
of the amino acid cystine. If cystine does not dissolve
in the urine, it can build up to form kidney stones.
cystitis (sis-TY-tis):
Inflammation of the bladder, causing pain and a
burning feeling in the pelvis or urethra.
cystoscope (SIS-tuh-skope):
A tool for examining the bladder. The procedure
is called cystoscopy (sis-TAH-skuh-pee).
