Abstract：Objective: To analyze the influencing factors of postoperative residual stones after treatment with flexible ureteroscope in urology department, and put forward relevant preventive measures.Methods: The clinical data of patients with renal calculi who were treated with flexible ureteroscope in the urology department of our hospital between January 2014 and December 2016 were retrospectively analyzed.According to the status of postoperative residual stones, the patients were divided into the residue group and non-residue group.The causes of postoperative residual stones were analyzed by univariate and Logistic multivariate regression analysis.Results: There were significant differences between the residue group and non-residue group in stone size ≥ 2 cm (71.11% vs.58.13%), stone burden >400 mm2 (42.22% vs.28.12%), operation time > 100 min (36.67% vs.23.12%), stone location (ratio of lower calyx, 55.56% vs.13.75%) and stone composition (ratio of calcium oxalate monohydrate, 66.67% vs.31.25%) (P<0.05).Logistic regression analysis showed that the risk factors for residual stones after treatment with flexible ureteroscope included stone burden, stone location and stone composition.Conclusions: The incidence of residual stones in patients with renal calculi after treatment with flexible ureteroscope is closely related to stone location and stone burden.It is suggested that the indications of treatment with flexible ureteroscope should be grasped to take corresponding measures according to the causes of residual stones.
