Urology Series- Ureteral Access Sheath, 11Fr×46cm
Introduction
Aiming at establishing a conduit during endoscopic procedures
facilitating the passage of endoscopes and other instruments into
the urinary tract.
A ureteral access sheath adapted for insertion into a urethra
includes an elongate tube.
Clinical application:
It is used to expand and establish channels for instrumentation
when patients with renal calculi or hydronephrosis are treated with
percutaneous nephrostomy dilation and endoscopic surgery.
In clinic, the expansion tube with sheath tube is implanted into
the human body under the guidance of guide wire, and the expansion
tube is removed, and the sheath tube is placed in the body for
surgical instruments or drainage catheter placement.
Because it can remain in the human body for a period of time,
reducing the pain of patients and the workload of nursing staff, it
is a common minimally invasive surgical instrument in clinic.
