目的:探讨双导丝引导进镜法在硬性输尿管镜手术中作用。方法:回顾分析114例应用双导丝引导法行经输尿管镜碎石手术患者的临床资料,统计术中一次性进镜成功率及进镜相关并发症的发生率。结果:114例患者均一次进镜成功,成功率为100%。术中输尿管口挫伤2例,少量出血4例。术后随访12周,未见明显远期并发症。结论:双导丝引导进镜法是一种安全、有效的方法,其进镜相关并发症发生率极低,且无需特殊处理。 Objective: To explore the role of guidewire guided double guide wire in rigid ureteroscopic surgery. Methods: The clinical data of 114 patients who underwent ureteroscopic lithotripsy with double guidewire guided method were retrospectively analyzed. The incidence of one-time endoscopic visit and the incidence of enteroscope-related complications were analyzed. Results: One hundred and seventy-four patients were successfully admitted to the hospital with a success rate of 100%. Intraoperative ureteral orifice contusion in 2 cases, a small amount of bleeding in 4 cases. After 12 weeks of follow-up, no obvious long-term complications were found. Conclusion: The guidewire approach with double guidewire is a safe and effective method. The incidence of complications related to enteroscopy is extremely low and requires no special treatment.
