智能控压输尿管软镜吸引取石术治疗2～3cm肾结石的临床研究OA

Objective To investigate the clinical efficacy and safety of intelligent pressure controlled retrograde renal surgery(IRIRS)for the treatment of 2-3cm kidney stones.Methods Totally 110 patients with renal stones with a diameter of 2-3cm admitted to Ganzhou People's Hospital from January 2019 to December 2021 were randomly divided into IRIRS group and control group(microchannel percutaneous nephrolithotomy with vacuum aspiration),with 55 cases in each group.The surgical time,rate of stone clearance,hemoglobin decrease,scores for postoperative pain,hospital stay and incidence of complications were systematically compared between the two groups.Results The surgical time and stone clearance rates at four weeks post-operation did not exhibit any statistically significant differences between the IRIRS group and the control group(P>0.05).The hospitalization time,hemoglobin decrease,and scores for postoperative pain in the IRIRS group were notably lower compared to the control group,with these differences being statistically significant(P<0.05).The difference in total postoperative complication rates between the IRIRS and control groups was not statistically significant(P>0.05).Conclusion IRIRS is an effective and safe method for treating renal stones with a diameter of 2-3 cm,meriting broader clinical adoption and application.
