Abnormal congenital opening of the male urethra on the undersurface of the penis
Condition associated with pathological changes in the renal interstitial tissue that
may be primary or due to a toxic agent, such as a drug or chemical, which results in
destruction of nephrons and severe impairment in renal function
High blood pressure that results from kidney disease
Elevated levels of urea and other nitrogenous waste products in the blood as a result
of the kidneys’ failure to expel these waste products in the urine; also called azotemia
The term uremia usually describes the illness that accompanies renal or kidney failure.
Malignant neoplasm of the kidney that occurs in young children, usually before age 5
The most common early signs of Wilms tumor are hypertension, a palpable mass, pain,
and hematuria.
Diagnostic Procedures
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 excre-
tion in urine
An increase in BUN level may indicate impaired kidney function.
Laboratory test that measures the rate at which creatinine is cleared from the blood
by the kidney
Creatinine clearance is the most common, most precise test that uses a blood and urine
sample to assess kidney function.
