ABSTRACT
ObjectiveTo evaluate the impacts of pereutaneous nephrolithotomy (PCNL) on perioperative renal hemodynamics.MethodsThe hemodynamics of operated renal arteries of 30 patients who underwent unilateral PCNL with single pole access were observed 1 day before and 5-7 days after operation with CDFI.Parameters were analyzed statistically.ResultsAfter operation,resistance index (RI) of renal arteries decreased (P<0.05).The diastolic flow statistically increased at main renal artery (MRA) of renal hilus,interlobar renal artery and interlobular renal artery (all P<0.05).After PCNL,in serious hydronephrosis patients,RI decreased (P<0.05) at segmental renal artery (SRA) and interlobar artery,end-diastolic flow velocity (Vmin) increased at interlobar renal artery (P<0.05).In moderate hydronephrosis patients,RI decreased at all renal arteries (P<0.05) after PCNL,Vmin increased at MRA and interlobular renal artery (P<0.05).In minor hydronephrosis patients,RI decreased at MRA and SRA,Vmin increased at SRA.In patients without hydronephrosis,RI changeed like serious hydronephrosis patients.ConclusionAfter PCNL,ipsilateral renal perfusion improves,renal diastolic flow increases and RI decreases.CDFI can be used to observe the blood perfusion of kidney,and provide quantitative information of renal hemodynamics.
