Abstract：Objective:To analyze the clinical effect of ureteral soft scope combined with negative pressure aspiration in the treatment of infectious kidney stones.Method:A total of 154 patients with infectious kidney stones were selected from Bijie Hospital of Traditional Chinese Medicine from January 2023 to January 2024.They were divided into two groups by random number table method,with 77 cases in each group.Ureteral soft scope was used for lithotripsis in control group.The observation group was treated with negative pressure aspiration when ureteral soft scope was used for lithotripsis.The calculus clearance rate and renal function were compared between the two groups.Result:The stone clearance rates of the observation group were 75.32%and 96.10%at 1 week and 4 weeks after surgery,respectively,which were higher than 59.74%and 81.82%of the control group,the differences were statistically significant(P<0.05).The operative time and indwelling time of the nephrostomy tube were shorter than those of the control group,and the intraoperative pressure in the renal pelvis was lower than that of the control group,the differences were statistically significant(P<0.05).The infectivity index content of the observation group at 2 h after operation was lower than that of the control group,and the differences were statistically significant(P<0.05).There was no significant difference in renal function between the two groups at 3 d after surgery(P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion:The combination of ureteral soft scope and negative pressure suction therapy has achieved good results in the treatment of infectious kidney stones,with high stone clearance rate,short surgical time,and few complications.
