Objective To investigate the incidence and risk factors of recurrence of renal calculi after intracavitary lithotripsy.Methods The clinical data of 190 patients with renal stones who un-derwent endoluminal lithotripsy in our hospital were retrospectively collected.Based on the results of CT,B-ultrasound,or X-ray examination of the urinary system during the 2-year follow-up period,therecurrence of renal calculi was analyzed.Univariate and multivariate Logistic regression were used to analyze the risk factors of stone recurrence.Results of 190 patients,49 patients experienced stone recurrence within 2 years after surgery,with a recurrence rate of 25.79％.Univariate Logistic regression analysis showed that body mass index(BMI),diabetes,smoking,older age and hyperten-sion were protective factors for stone recurrence.Multivariate Logistic regression analysis showed that diabetes and smoking were risk factors for stone recurrence,while age and hypertension were protec-tive factors for stone recurrence.Conclusion The recurrence of renal stone after intracavitary litho-tripsy is common.Diabetes and smoking are risk factors for the recurrence of renal stone,while older age and hypertension are protective factors.
