介绍一种逼真的腹膜后腹腔镜下肾盂输尿管离断成形术的训练模型

目的:评估一种新的腹膜后腹腔镜肾盂输尿管离断成形术的体外训练模型。方法:利用橡皮泥、金属夹、鱼鳔和猪输尿管模拟肾盂和输尿管,用5块木板搭建成腹膜后空间。利用此模型对6名住院医师和3名高年资主治医师进行10轮模拟训练,记录吻合时间,并评估吻合质量。结果:6名住院医师的吻合完成率从第一次的33%上升至最后的100%,吻合时间从(42.68±11.12)m in降至(23.27±7.69)m in,吻合质量则从(4.68±1.83)分升至(6.27±1.15)分。6名住院医师的吻合能力经过10轮训练后,已接近于3名未受过训练的高年资主治医师。结论:此模型简易且逼真,能较好地模拟腹膜后腹腔镜肾盂输尿管离断成形术,不仅有效区分了不同水平的受训人群,而且明显提高了吻合水平,是初学者理想的体外训练模型。

A vivid model for training of retroperitoneal laparoscopic dismembered pyeloureteroplasty

Objective:To create a novel model for training in retroperitoneal laparoscopic dismembered pyeloureteroplasty and evaluate the effect of this model.Methods:Kidney model was made of plasticine,metal clip and swimming bladder of carp.Ureter was substituted by a 10-centimeter long porcine ureter.The retroperitoneal cavity was simulated by 5 boards which were fixed together by detachable hinges.6 residents and 3 attending doctors were trained with 10 rounds of ureteropelvic anastomosis according to the standard...
