Abstract: Objective To analyze the related factors of the recurrence of stones in the patients with urinary system infection after percutaneous nephrolithotomy. Methods A total of 70 elderly patients with urinary tract infection after percutaneous nephrolithotomy in our hospital from August 2016 to August 2018 were enrolled. The patients were followed up for 2 year, and the stone recurrence rate was counted.The basic data of the patients with relapse and those without relapse were compared. Logistic multivariate analysis was used to determine the independent risk factors affecting the recurrence of stones in the patients with urinary system infection after percutaneous nephrolithotomy. Results After 2 year of follow-up, 16 patients had relapse of stone, with the recurrence rate of 23.19%. There were no statistically significant differences in composition ratio of gender, complications, extent of disease, hydronephrosis,types of infection, and the levels of preoperative serum creatinine, preoperative urea nitrogen, operation time, and hospital stay between the two groups (P>0.05).There were significant differences in age, chemical components of kidney stone, preoperative urine white blood cell, history of endocrine diseases,surgical stone clearance rate, and 24-hour urine volume before operation between the two groups (P<0.05). Logistic multivariate analysis showed that age> 70 years old, infectious stones, preoperative urine routine white blood cells "+++", history of endocrine diseases and surgical stone clearance rate≤80% were independent risk factors that affected the recurrence of stones in the patients with urinary system infection after percutaneous nephrolithotomy. Conclusions Age> 70 years old, infectious stones, and preoperative urine white blood cells "+++", history of endocrine diseases, surgical stone clearance rate≤80% are independent risk factors that affect the recurrence of stones in the patients with urinary system infection after percutaneous nephrolithotomy.
