Short Description:

For veterinary professionals treating feline ureteral obstructions, the Subcutaneous Ureteral Bypass (SUB) system offers a reliable, minimally invasive solution. Ureteral obstructions, whether caused by ureterolithiasis, strictures, or other etiologies, can rapidly compromise renal function and become life-threatening if not addressed promptly.

The SUB procedure has become the standard of care in many leading veterinary institutions worldwide, largely replacing traditional surgical approaches due to its lower morbidity and better outcomes.

Why do we use？

Clinical Indications

The Lingze SUB system is designed to treat benign ureteral obstructions (BUO) in cats, including:

1-Obstructive ureterolithiasis (ureteral stones) – the most common cause of feline ureteral obstruction

2-Ureteral strictures – narrowing of the ureter that impedes urine flow

3-Obstructive pyonephrosis – infection and pus accumulation in the kidney due to obstruction

4-Other obstructive etiologies where traditional surgery is challenging or not feasible

Key Advantages of Our SUB System

1. Efficient and Time-Saving Procedure
The Lingze SUB system is designed for efficient placement, significantly reducing surgical and anesthesia times compared to traditional ureteral surgery. In clinical studies, unilateral SUB placement can be completed in approximately 55–75 minutes, helping to minimize anesthesia-related risks for feline patients. 

2. Versatile Configuration for Unilateral and Bilateral Obstructions
Our system offers dedicated configurations for both unilateral (LDY001) and bilateral (LDY003) obstructions, providing surgical flexibility to address varying clinical presentations with a single, integrated solution.

3. Designed to Reduce Common Complications
Device kinking, mineralization, and chronic urinary tract infections are recognized long-term complications associated with SUB devices. The Lingze Kesi Tong system incorporates design features that help minimize these issues, supporting more predictable long-term outcomes.

4. Suitable for Complex Cases
The SUB approach can be successfully used for nearly all obstructive etiologies, including cases where ureteral stenting may fail or traditional surgery poses high risks. This makes it an invaluable tool in the veterinary interventionalist's arsenal.

5. Proven Clinical Foundation
The SUB technique has been extensively studied and validated. Research has demonstrated its effectiveness in improving renal function (reducing creatinine and BUN levels) with good to excellent outcomes in the largest published case series.
