Abstract：Objective To investigate the risk factors for recurrence of lumbar disc herniation（LDH）after percutaneous transforaminal discectomy（PTED）.Methods The research subjects selected 80 patients with lumbar intervertebral disc herniation .All subjects were treated with PTED,and they should be followed up in time within 6 months after the operation.The recurrence of LDH within 6 months after the operation was counted and grouped,and the basic information of all subjects,including gender,age,body mass index（BMI）,prominent type,hyperlipidemia,hypertension,diabetes,smoking,and drinking,were recorded and recorded.To analyze the influencing factors of recurrence of LDH after PTED treatment.Results 9 cases of 80 LDH patients relapsed after PTED treatment,the recurrence rate was 11.25%;Univariate analysis showed that the recurrence of LDH patients after PTED treatment was not affected by gender,hyperlipidemia,hypertension and alcohol consumption,and the difference was not statistically significant（P>0.05）,but may be affected by age,BMI,type of prominence,diabetes,and smoking,and the difference was statistically significant（P<0.05）;Logistic regression analysis found that age,BMI,type of prominence,diabetes,and smoking were all significant Influencing factors of recurrence after PTED treatment in LDH patients（OR>1,P<0.05）.Conclusion Patients with older age,high BMI,prominent type,diabetes,and smoking are at higher risk of relapse after PTED treatment,and targeted interventions can be given early to reduce postoperative recurrence.
