Abstract
Silent kidney is a serious symptom. It can be defined as an aquired asymptomatic afunction of one kidney founded accidentally on IVP or radionuclide imaging.
Usually there is not renal failure, because the second kidney is able to excrete endogenous metabolites. The most common cause of this condition is unilateral obstruction of urinary tract.
Rarely it can be caused by some infections, tumors of the kidney or diseases of the renal vessels. Complete urological examination must be done if silent kidney is detected.
This enables proper treatment saving functioning kidney in some patients.
