Abstract:Objective?To compare the efficacy of holmium laser lithotripsy with flexible ureteroscope and pneumatic lithotripsy under rigid ureteroscope in the treatment of ureteral calculi with hydronephrosis.?Methods?The 106 patients with ureteral calculi and hydronephrosis admitted to our hospital from December 2017 to December 2019 were randomly divided into the observation group and the control group according to the random number table method, each with 53 cases. The patients in the observation group were treated with holmium laser lithotripsy with flexible ureteroscope, while the patients in the control group were treated with pneumatic lithotripsy under rigid ureteroscope. The one-time clearance rate of ureteral calculi, operation situation, postoperative complications, and the changes of serum adrenocorticotropic hormone (ACTH), C-reactive protein (CRP) and cortisol (COR) levels 3d prior to and after the operation were compared between the two groups.?Results?There was no significant difference in the clearance rate of ureteral calculi between the observation group and the control group (P > 0.05). The duration of hospitalization and operation in the observation group was shorter than that in the control group (P < 0.05). The postoperative complications in the observation group were fewer than those in the control group (P < 0.05). In addition, the differences of serum ACTH, CRP and COR before and after operation in the control group were higher than those in the observation group (P < 0.05).?Conclusions?The holmium laser lithotripsy with flexible ureteroscope for the treatment of ureteral calculi with hydronephrosis contributes to fewer postoperative complications and can effectively reduce the occurrence of stress reaction, which is of value for further clinical application.
