Идентичную трубку обрабатывают в тех же услови х, что и в примере 1. Ее используют в виде мочеточникового протеза дл  собаки, она не показывает никаких следов инкрустации через 6 мес цев.The identical tube is treated under the same conditions as in Example 1. It is used as a ureteral prosthesis for a dog, it does not show any signs of incrustation after 6 months.

Мочеточниковые протезы, обработанные как в примере 1, используютс  дл  человека и функционируют в течение 1 года и более.Ureteric prostheses, treated as in Example 1, are used for humans and function for 1 year or more.
