Abstract

The invention discloses a ureteral stent and a use method thereof, and relates to the technical field of medical instruments, the ureteral stent comprises: an outer tube capable of contracting and expanding in the radial direction of the outer tube; the inner-layer pipe is independent of the outer-layer pipe, and the inner-layer pipe can be arranged at a local position in the outer-layer pipe and abuts against and is anchored to the inner wall of the outer-layer pipe. The ureteral stent can solve the problems that an existing ureteral stent is poor in supporting performance, poor in drainage effect and prone to blockage.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ureteral stent and a method for using the same. Background technique [0002] The ureters are the passages in the body that carry urine from the kidneys to the bladder. Ureteral stent is a commonly used medical device in urology. It is mainly used in the treatment of various benign and malignant urinary system diseases such as kidney stones, kidney transplantation, hydronephrosis, ureteral stenosis and dilatation, and has the function of supporting the ureter and draining urine. [0003] At present, one of the ureteral stents is a polyurethane double-J ureteral stent. The stent is placed in the ureter. The two ends of the ureteral stent are J-shaped ends, which are generally coiled into a pigtail shape. They are located in the kidney and the bladder, respectively. Used to prevent upward and / or downward migration of the stent due to patient movement. Since this uretera...
