Abstract: ［Abstract］ Objective To evaluate the safety of percutaneous nephrolithotomy （PCNL） in semi?supine position and summarize the practical experience. Methods According to the different operation positions， 68 patients who received PCNL in our hospital from October 2016 to December 2018 were divided into observation group （34 cases） and control group （34 cases）. The former group used semi?supine position in PCNL， while the control group chose traditional position （prone position）. Hemodynamic changes， clinical effects and complications were observed and compared between the two groups. Results The blood oxygen saturation， pulse and blood pressure in the observation group were relatively stable during the perioperative period. There were significant changes in the related indicators in the control group from the posture to the end of the operation， including the decrease of blood pressure and the increase of heart rate， and the incidence of intraoperative restlessness. The complications and hospitalization time of the two groups were similar. Conclusion In PCNL， the use of semi?supine position is conducive to reducing the changes of blood pressure and heart rate， reducing the agitation of patients during the operation， and the operation is safe.
