Abstract:
Objective To evaluate renal hemodynamic changes in hydronephrosis children with no image on intravenous urography by color doppler flow image(CDFI). Methods The resistance indexes(RIs)in main renal arteries(MRAs),interlobar renal arteries(IRAs)and arcuate renal arteries(ARAs)were measured in 48 children with hydronephrosis with no image on intravenous urography.The thickness and area were also measured in hydronephrotic kidneys.Resistive index ration(RIR=hydronephrotic kidneys RI/contralateral RI)was calculated. And pathological changes of kidneys were graded in these cases.Spearman's correlation test was used to compare RIR and pathological grades in these kidneys. Results In healthy and hydronephrotic kidneys,the relevant parameters were as fol1.13±0.14,1.14±0.09,respectively in MRAs,IRAs,ARAs in hydronephrotic kidneys(P＞ness,area of hydronephrotic kidneys(P＜0.05),also between RIR and thickness,araa(P＜0.05),MRAs,IRAs,ARAs and pathologic grades(P＜0.05),especially in IRP(s(r=0.795,P＜0.01).Conclusions RIR of IRA could be an ideal parameter of renal hemodynamics to evaluate renal damage in children with congenital hydronephrosis with no image on intravenous urography.
