title: [X-ray evaluation of renal function in children with hydronephrosis as a criterion in the selection of therapeutic tactics].
abstract: The anatomic parameters of the kidneys and the rate of glomerular filtration were measured in 77 children with unilateral hydronephrosis and in 27 children with nonobstructive diseases of the urinary tract according to the clearance of an opaque medium during excretory urography. Alterations in the anatomic parameters of the kidneys in obstructive affection did not reflect the gravity of functional disorders. It has been established that there is a possibility of carrying out a separate assessment of filtration function of the hydronephrotic and contralateral kidneys. A new diagnostic criterion is offered, namely an index of relative clearance, which enables one to measure the degree of compensatory phenomena in the preserved glomeruli and the extent of sclerotic process. It has been demonstrated that accurate measurement of the functional parameters of the affected kidney should underlie the treatment choice in children with unilateral hydronephrosis.
