Training on porcine models improves dexterity in ureteroscopy

目的评价猪模型在住院医师输尿管镜技术培训中的应用效果。方法雌性猪4只,全身麻醉后由8名住院医师进行输尿管镜及输尿管支架管置入术。结果输尿管镜检查均顺利,每人重复操作3次,平均检查时间为(7.5±1.4)min,所有支架管均成功留置,平均留置时间(4.5±1.3)min。无输尿管穿孔、剥脱等并发症。所有实验猪均正常苏醒,术后8 h正常进食,3例出现轻度血尿。术后2 d观察实验猪活动正常,进食及排便均正常,血尿消失。结论猪模型是输尿管镜技术较好的培训模型,接近真实手术,值得推广。

Objective To validate training on porcine models as a tool to improve dexterity in semi-rigid ureteroscopy and stenting. Methods Eight urology residents were evaluated when performing semi-rigid ureteroscopy and stenting on four porcine model. All standard equipment and instruments, including fluoroscopy and ureteroscope, were available. Results All the ureteroscopies and stenting procedures were successfully performed. The ureteroseopy was repeated for 3 times by each resident. The mean time of ureteroscopy and stenting were （7.5＋l.4）min and （4.5＋l.3）min, respectively. No perforation and stripping occurred during all the procedures. All the animals were alive, 3 of those had mild hematuria after the procedure and disappered after two days. All residents felt more familiar with the instruments and the procedure after the training. Conclusions Training on porcine models is an effective means of skills acquisition for ureteroscopy procedure. It is recommendable before operating on patients.
