The key to successful placement and outcomes are the training laboratories and full support offered by the inventors and patent holders (Drs. Allyson Berent and Chick Weisse), the distributors of the device (Norfolk Vet Products, Sanei America Corp, Scutum and AdVetis-Medical), and instructors in the laboratories (Drs. Berent, Weisse and Asano).

The Subcutaneous Ureteral Bypass (SUB) device has been used as the treatment of choice for various causes of ureteral obstructions in institutions and practices throughout the world. This device was created 8 years ago, and has since been tested for both safety and efficacy in hundreds of pets. The outcomes have been reported to be superior to other alternatives in both the short-term and long-term with low morbidity and mortality rates. The key to successful placement and outcomes is training. We offer training laboratories and full support by the inventors of the device (Drs. Allyson Berent and Chick Weisse), the distributors of the device (Norfolk Vet Products and Sanei America Corp), and instructors in the laboratories (Drs. Berent, Weisse and Asano).
