Abstract 【Objective】 To compare the therapeutic effect of Sun's tip-flexible ureterorenoscopy and minimally invasive percutaneous nephrolithotomy for the treatment of 2-3cm renal inferior calyx stone in the elderly.【Methods】From June 2016 to July 2018, 80 interns were randomly divided into Sun's tip-flexible ureterorenoscopy group (40 cases) and minimally invasive percutaneous nephrolithotomy group (40 cases). They were treated by retrograde intrarenal surgery and minimally invasive percutaneous nephrolithotomy. The one-time success rate and stone clearance rate, operative time, intraoperative blood loss, postoperative hospitalization days, postoperative complications and trauma indicators were compared.【Results】There was no significant difference between the two groups (92.5% vs 95.0%,χ2=0.213, P>0.05). The operation time of the Sun's tip-flexible ureterorenoscopy group was longer than that of the mPCNL group, and the hospitalization time and intraoperative blood volume were lower than that of the mPCNL group (P<0.05). The serum CRP, TNF-α and IL-6 levels in the two groups were higher than those in the immediate and 72 hours postoperatively, and the serum CRP, TNF-α and IL-6 levels in the mPCNL group were higher than those in the Sun's tip-flexible ureterorenoscopy group (P<0.05). The incidence of postoperative complications in the Sun's tip-flexible ureterorenoscopy group was 5% (2 / 40) lower than that in the mPCNL group 25.0% (10 / 40), the difference was statistically significant (P<0.05). 【Conclusion】Sun's tip-flexible ureterorenoscopy is better in the treatment of 2~3cm lower calyceal calculi in the elderly, which is similar to that of mPCNL. At the same time, it has the advantages of quick recovery, less complications, small wound and less bleeding.
