自制输尿管扩张器治疗中下段结石合并输尿管下段狭窄的临床研究

Objective To explore the application value of self-made ureteral dilators in the clinical treatment of patients with middle and lower ureteral calculi combined with lower ureteral stenosis. Methods From February 2023 to October 2024, 120 patients with ureteral calculi combined with lower segment stenosis in the Department of Urology of Shenzhen Hengsheng Hospital were selected. The above 120 research samples were grouped by the random number table method and divided into the control group (n=60) and the observation group (n=60). The control group received onetime ureteral catheter dilation treatment, while the observation group was treated with a self-made ureteral dilator. The operation duration, hospital stay duration, postoperative cost, postoperative pain degree and incidence of ureteral injury of the two groups of patients were compared. Results The operation duration and hospital stay duration of the observation group were both shorter than those of the control group (P＜0.05). The comparison of postoperative pain scores in the observation group was lower than that in the control group (P＜0.05). The postoperative cost of the observation group was also lower than that of the control group (P＜0.05). Furthermore, the incidence of ureteral injury in the observation group was significantly lower than that in the control group (P＜0.05). Conclusion The self-made ureteral dilator can effectively relieve the pain of patients with middle and lower ureteral calculi combined with lower ureteral stenosis in the treatment of patients, and reduce the incidence of complications.
