Abstract: ［Abstract］ Objective To investigate the influence of on extracorporeal shock wave lithotripsy（ESWL）on renal blood flow index. Methods Forty?eight patients from August 2016 to April 2018 were included in the study. The mean age was 50.3±14.1 years. The spectrum of blood flow of both the treated and the opposite kidney was investigated by using color Doppler ultrasonography including resistive index（RI），pulsatility index （PI） and acceleration time （AT）. Results The ESWL treatment caused a statistically significant increases of the RI in the ipsilateral kidney as well as in the opposite kidney（P<0.001 vs pre-ESWL）. The RI decreased after 92 hours after ESWL. PI substantially increased afterESWL in both kidneys（P<0.001 vs pre?ESWL），and decreased after 92 hours. There were statistically significant correlations shown between RI and age （r=0.562，P<0.05）. Conclusion ESWL for renal stones causes temporary impairment of the renal perfusion in both ipsilateral and contralateral kidneys. The patients age may be the main factor.
