To create a simple, inexpensive, and reproducible animal model to provide a new training option for performing urethrovesical anastomosis during laparoscopic radical prostatectomy.
Development and testing were carried out in 2008. The materials used included a laparoscopic training box, video camera, monitor, needle holder, sutures, and non-eviscerated chickens weighing more than 2 kilograms. The model was prepared with a new perception of a structure similar to the human pelvis. To create the anastomosis, we used the gizzard (bladder neck) and the rectum (urethra). Once the model was placed in the box, the anastomosis was performed under very similar anatomical conditions to real procedures. Anastomosis quality was assessed by means of a permeability test and transanal endoscopy.
The operating field is very similar to the human pelvis. The tissues have a quality, texture, and diameter resembling those of the urethra (rectum) and the bladder neck (gizzard), and offer the opportunity to practise anastomosis and anterior racket.
The model for urethrovesical anastomosis using the chicken gizzard and rectum is simple, easily available, inexpensive and reproducible. The anatomy of the chicken and the characteristics of its tissues allow for training under conditions very similar to those present in human cases.
创建一种简单、廉价且可重复的动物模型，为腹腔镜根治性前列腺切除术中进行尿道膀胱吻合术提供一种新的训练选择。
于2008年开展模型的开发与测试。所用材料包括一个腹腔镜训练箱、摄像机、监视器、持针器、缝线以及体重超过2千克的未去内脏的鸡。该模型基于对一种类似于人体骨盆结构的新认知而制备。为进行吻合术，我们使用鸡胗（膀胱颈）和直肠（尿道）。将模型置于箱内后，在与实际手术非常相似的解剖条件下进行吻合术。通过渗透性测试和经肛门内镜检查评估吻合质量。
手术视野与人体骨盆非常相似。组织的质量、质地和直径与尿道（直肠）及膀胱颈（鸡胗）相似，为练习吻合术和前壁缝合提供了机会。
使用鸡胗和直肠的尿道膀胱吻合模型简单、易于获取、成本低廉且可重复。鸡的解剖结构及其组织特性使得在与人类病例非常相似的条件下进行训练成为可能。
