Analysis of the recurrence rate and risk factors of renal calculi after intracavitary lithotripsy

    摘要
  • 摘要:
    目的  探讨肾结石腔内碎石术后结石复发的发生率及危险因素。
    方法  回顾性收集接受腔内碎石手术治疗的190例肾结石患者的临床资料，根据术后2年随访过程中CT、泌尿系彩超或泌尿系平片检查结果明确有无结石复发，采用单因素及多因素Logistic回归分析探讨结石复发的危险因素。
    结果  190例患者中, 49例患者术后2年内出现结石复发，复发率为25.79%。单因素Logistic回归分析显示，体质量指数(BMI)、糖尿病、吸烟、年龄和高血压是结石复发的影响因素。多因素Logistic回归分析显示，糖尿病和吸烟是结石复发的危险性因素，而年龄大和高血压是结石复发的保护性因素。
    结论  肾结石腔内碎石术后结石复发较为常见，糖尿病和吸烟是结石复发的危险性因素，而年龄大和高血压是结石复发的保护性因素。

     

    Abstract:
    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 underwent 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 hypertension 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 protective factors for stone recurrence.
    Conclusion  The recurrence of renal stone after intracavitary lithotripsy is common. Diabetes and smoking are risk factors for the recurrence of renal stone, while older age and hypertension are protective factors.
