dysuria

painful or difficult urination, typically caused by a urinary tract condition, such as cystitis

edema

abnormal accumulation of fluid in the cells, tissues, or other parts of the body that may be a sign of kidney failure or other disease

end-stage renal disease (ESRD)

kidney disease that has advanced to the point that the kidneys can no longer adequately filter the blood and, ultimately, requires dialysis or renal transplantation for survival; also called chronic renal failure (CRF)

renal hypertension

high blood pressure resulting from kidney disease

urinary tract infection (UTI)

infection of the kidneys, ureters, or bladder by microorganisms that either ascend from the urethra or spread to the kidney from the bloodstream

Wilms tumor

malignant neoplasm of the kidney that occurs in young children, usually before age 5, and includes common early signs such as hypertension, a palpable mall, pain, and hematruia

blood urea nitrogen (BUN)

laboratory test that measures the amount of urea (nitrogenous waste product) in the blood and demonstrates the kidneys' ability to filter urea from the blood for excretion in urine

culture and sensitivity (C&S)

laboratory test that isolates and grows colonies of microorganisms to identify a pathogen and to determine which drugs might be effective for combating an infection
