Abstract：
OBJECTIVE: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal.
METHODS: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility.
RESULTS: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes.
CONCLUSIONS: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

摘要：
目的：评估猪输精管作为输精管切除术逆转的现实显微外科训练模型的可行性。
方法：该模型使用猪睾丸（输精管），它们通常被丢弃在大型街头市场，因为它们不是巴西美食的一部分。精索被仔细解剖,输精管被隔离，长度为10厘米。建立了一个5cm2的四边形纸，以划定手术训练场。该模型的目的是仅在输精管已经分离时模拟显微外科手术步骤。分析的参数是：重现该技术的可行性，血管血管造口术前后通畅，模型的成本，易于收购，易于处理，执行时间,和模型再现性。
结果：模拟器显示低成本。所有制作的模型都是可行的，纹理类似于人类，在100%的程序中获得了阳性通畅性。输精管的内径和外径在0.2-0.4毫米和2-3毫米之间变化，分别,平均长度为9±1.2厘米。总手术时间为43.28±3.22分钟。
结论：提出的现实模型被证明对进行输精管切除术逆转训练是可行的，由于成本低,容易获取,和易于处理，并提供与人类相似的组织特征。
