The urology team at Jiangsu Provincial Government Hospital has successfully implanted a EVT 195mm Ureteral Stent System in a 57-year-old male patient with proximal ureteropelvic junction (UPJ) stenosis. The stent expanded smoothly and the procedure was completed successfully. Physicians praised our product for its superior ease of use and radiographic visibility compared to other brands.

The First Use of EVT 195mm Ureteral Stent System at Jiangsu Provincial Government Hospital

Recently, the urology department of Jiangsu Provincial Government Hospital performed a procedure to insert a EVT 195 mm Ureteral Stent System. The patient was a 57-year-old man who had been admitted to hospital due to a stricture near the ureteropelvic junction (UPJ).

The procedure was performed under C-arm fluoroscopy guidance. Following repeated positioning to ensure the stent spanned the stenotic segment, stent placement and expansion were successfully completed. Final imaging confirmed proper stent expansion and unobstructed flow. The operation was completed safely and smoothly.

Doctors' evaluations and comparisons of the EVT Ureteral Stent System

Following the procedure, Director Zhang highly praised the EVT Ureteral Stent System, noting two key advantages over other brands:

1. Ease of use: Imported stents are supplied in a curved state within their packaging and must be straightened on the operating table before use, which increases the risk of inaccurate stent deployment. The EVT stent’s packaging allows immediate use, reducing operational complexity.
2. Radiographic Visibility: The blue radiopaque marking at the proximal end of the EVT introducer sheath is clearly visible, allowing intuitive confirmation of stent position. other brands use frosted markers, requiring reliance on C-arm fluoroscopy for accurate placement.
3. Enhanced Safety and Efficiency: The EVT Ureteral Stent System features a high-visibility blue ring at the sheath tip, allowing clear identification of stent position and deployment status without continuous C-arm fluoroscopy. This simplifies the procedure while reducing radiation exposure for both patients and clinicians.   

Advantages and Clinical Significance of the EVT Ureteral Stent System

The EVT 195 mm Ureteral Stent System demonstrates the following benefits in UPJ stenosis and urinary tract procedures:

· Simplified Operation: Reduces procedural complexity

· Clear Radiographic Visibility: Enables precise stent placement

· High Compliance Design: Smooth expansion minimizes procedural risk

This first successful implantation not only provides the hospital’s urology department with a high-quality device option, but also strengthens the clinical impact and market presence of EVT products.
