摘要: Objective. To evaluate the Doppler sonographic findings of left renal vein in children with orthostatic proteinuria comparison healthy and to propose more reliable criteria for diagnosing nutcracker syndrome children. Methods. 47 27 control subjects were compared. The diagnosis was made on basis clinical laboratory findings. peak velocity anteroposterior diameter measured at hilar aortomesenteric portions vein. means ± 2 SD ratio between calculated used as cutoff levels syndrome. Results. ratios 5.21 2.55 patient group 2.57 0.70 group. 5.31 2.65 2.77 0.69 We set level mean value (3.98 4.16 ratio).
