Introduction for Ureteral Access Sheath

June 07,2023

In recent years, with the advancement and deepening of minimally invasive concepts and the optimization and upgrading of laparoscopic equipment, flexible ureteroscopy has gradually attracted clinical attention in urology, and flexible ureteroscopy lithotripsy has gradually become one of the main treatment methods for upper urinary tract stones.

Flexible ureteroscope retrogrades in the urinary tract of the human body. With the cooperation of endoscopic equipment, holmium laser can be used for lithotripsy. It has a wide range of indications, improves the shortcomings of traditional open surgery and hard mirror surgery, reduces trauma, and has a low incidence of complications. The hospitalization time is short, the safety is high, and the curative effect is reliable.


The advantages of flexible ureteroscopic lithotripsy are as follows:

 First, there is basically no trauma, and stones are broken through the natural passage (urethra) of the human body without drilling holes. The second is that the risk is lower, the risk of massive bleeding and "losing a kidney" is basically 0, and the kidney function is protected to the maximum extent. The third is that the postoperative recovery is fast. Basically, the urinary catheter can be removed on the second day, and the patient can be discharged from the hospital on the third day.


Ureteral Access Sheath

Ureteral Access Sheath is suitable for the establishment of passages for instruments such as endoscopes to enter the urinary tract in urological operations.





✔Corrosion resistance: ureteral access sheath has good corrosion resistance;
✔Breakage force: each part of the introducer sheath and dilator can withstand a static tensile force of 15N for 15s without breaking or falling off;
✔Radiation detectability: the access sheath body and dilator body can be detected by X-rays;
✔Anti-deformation: The introducer sheath and dilator have no obvious deformation affecting their function under 20KPa negative pressure;
✔Sterile: Sterilized by ethylene oxide, the product is sterile;
✔Ethylene oxide residue: The ethylene oxide residue in the ureteral introducer sheath is not more than 10 μg/g.
