Abstract
Is the assesment of renal function based on dynamic renal scintigraphy (DRS) with merkaptoacetyltriglycin (MAG3) reliable image of the renal function in unilateral congenital hydronephrosis? We investigated 47 children (31 boys, 16 girls) at the age of 1 months to 18 years (average 5,5 years) with unilateral hydronephrosis (22x on the right side, 25x on the left side) and with normal finding on the other kidney.We were evaluating the results of DRS with 99mTc MAG3 before and 6 months after successful pyeloplasty (improvement of outflow of urine on post-surgical DRS). The asesment of renal function by dynamic scintigraphy with MAG3 was overvalued in 25 % of our children.
Supranormal function of kidney was in majority false.
