Evaluation on curative effect of ureteroscopic holmium laser lithotripsy combined with N-trap intercepted basket in treating middle and upper ureteral stones
Objective:To study the clinically curative effect of ureteroscopic holmium laser lithotripsy combined with intercepted basket of capture and extraction device for stone(N-trap)in treating middle and upper ureteral stones.Methods:A total of 112 patients with middle and upper ureteral stone who were diagnosed and treated in the Department of Urology of the Second Affiliated Hospital of Wannan Medical College from September 2020 to September 2022 were prospectively selected as the study subjects,and they were divided into two groups according to the random number table method,with 56 cases in each group.The control group was treated with ureteroscopic holmium laser lithotripsy alone,and the observation group was treated with ureteroscopic holmium laser lithotripsy combined with N-trap intercepted basket for treatment.The related indicators of surgery,the stone removal effect,renal function indicators,postoperative renal mass,postoperative recurrence and postoperative complications between two groups were compared.The scores of the Wisconsin Stone Quality of Life(WISQOL)questionnaire were used to compare and evaluate the postoperative quality of life between the two groups.Results:There were no significant differences in intraoperative operation time and intraoperative blood loss between the two groups(P>0.05),and the postoperative hospitalization time in the observation group was significantly shorter than that in the control group(t=3.464,P<0.05).The success rate of one-time lithotripsy and the clearance rate of stone within 30 d in the observation group were significantly higher than those in the control group,and the upward movement rate of stones of the observation group was significantly lower than that in the control group,and the difference was statistically significant(x2=6.698,7.240,5.489,P<0.05),respectively.The postoperative serum creatinine(Scr),blood urea nitrogen(BUN)and urine microalbumin(UMA)in the observation group were significantly lower than those in the control group,and the differences were statistically significant(t=6.320,8.115,9.231,P<0.05),respectively.The degree of hydronephrosis at 3,6 and 12 months after surgery in the observation group were significantly lower than those in the control group,and the differences were statistically significant(t=3.218,3.345,2.985,P<0.05),respectively.The recurrence rates at 6 and 12 months after surgery in the inspection group were significantly lower than those in the control group,and the differences were statistically significant(x2=5.114,5.783,P<0.05),respectively.The incidence of postoperative complication in the observation group was significantly lower than that in the control group(x2=4.865,P<0.05).The total score of the each dimension of WISQOL scale,and the total score of energy,sleep status,physical symptoms and overall emotion in the observation group were significantly higher than those in the control group,and the differences were statistically significant(t=3.734,3.889,3.903,4.340,4.650,P<0.05),respectively.Conclusion:The curative effect of ureteroscopic holmium laser lithotripsy combined with N-trap intercepted basket is certain,which can effectively improve the clearance rate of stone,and shorten the postoperative hospitalization time,and reduce the incidence of postoperative complications and recurrence rate,and promote the recovery of renal function,and improve the quality of life of patients after surgery.
