A Disposable Ureteral Stent Kit is a medical device that contains a soft, hollow, plastic tube called a ureteral stent. The stent is placed in the ureter, which is the tube that carries urine from the kidney to the bladder. The top portion of the stent has a small curl that sits in the kidney and the opposite end curls in the bladder. The stent allows urine to drain easily from the kidney into the bladder.
Ureteral stents are used when there is a blockage in the ureter, for example, from a kidney stone. The stent allows urine to flow through the ureter around the blockage, helping to decrease pain and allowing the kidney to function as normally as possible. In some cases, a stent may be placed if there is an infection associated with a kidney stone to help drain the infected urine. If kidney stone surgery is required, a stent may also be placed in the ureter after surgery to allow it to heal and protect it from swelling.
One advantage of using a disposable ureteral stent kit is that it offers greater flexibility and can be cost-effective compared to reusable flexible cystoscopes (re-FCs). The disposable ureteral stent kit is made of imported high molecular material that has excellent biocompatibility. The large cavity and multiple side holes allow for a high flow rate. It also provides clear imaging and accurate positioning under X-ray. The smooth inner and outer surfaces ensure smooth drainage. Additionally, the disposable ureteral stent kit is specially designed to control urine reflux into the renal pelvis.”
However, having a ureteral stent can cause some discomfort such as hematuria, backache and frequent urination and may require a minor in-office procedure by a doctor for removal.
