[Comparative assessment of the doses received by patients during radiodiagnosis of the urinary system].

The authors present some literature data, estimated data and results of phantom measurements in order to give comparative assessment of radiation exposure of patients during radio-contrast and radionuclide investigation of the urinary system. The importance and distribution of doses absorbed by organs and tissues (HT) and effective equivalent doses (HE) in two most commonly used radiodiagnostic methods were studied. In radiocontrast urography (RCUG) the maximum values of tissue doses were noted for the female gonads and the organs adjacent to the kidneys (the liver, pancreas, etc.
