Objective To explore the application value of flexible ureteroscope combined with flexible ureteral access sheath in patients with renal calculi.Methods A total of 40 patients with renal calculus admitted to the Third Affiliated Hospital of Gannan Medical University from January to December 2022 were selected as research objects.According to ran-dom number table method,they were divided into control group and observation group,with 20 cases in each group.Both groups were treated with flexible ureteroscopic lithotripsy.The control group was treated with non-flexible ureteral access sheath,while the observation group was treated with flexible ureteral access sheath.The stone clearance rate,surgical indi-cators,pain degree,negative emotions,quality of life,and incidence of complications were compared between the two groups.Results The stone clearance rate of the observation group at 1 day and 1 month after operation were higher than those of the control group,and the difference were statistically significant(P＜0.05).The operation time of the observation group was shorter than that of the control group,and the intraoperative blood loss was less than that of the control group,and the differ-ences were statistically significant(P＜0.05).Before operation,there were no statistically significant differences in pain de-gree,negative emotion and quality of life scores between the two groups(P＞0.05).The pain visual analogue scale(VAS)score of the observation group was lower than that of the control group 3 days after operation,the scores of self-rating de-pression scale(SDS)and self-rating anxiety scale(SAS)were lower than those of the control group 1 month after operation,and the scores of social relationship,physical health,mental health and surrounding environment in the World Health Orga-nization quality of life brief assessment(WHOQOL-BREF)1 month after operation were higher than those in the control group,and the differences were statistically significant(P＜0.05).The total incidence of complications in the observa-tion group was lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion Flexible ureteroscope combined with flexible ureteral access sheath has obvious advantages in shortening the operation time and reducing intraoperative blood loss compared with non-flexible ureteral access sheath,which is conducive to improving the stone clearance rate,reducing the risk of complications,reducing the pain and negative emotions of patients,and im-proving the quality of life.
