The ureteral stent is a medical device that is used to treat a variety of conditions related to the urinary system. It is a thin, flexible tube that is inserted into the ureter, which is the tube that connects the kidney to the bladder. The stent is designed to help keep the ureter open, which can help relieve pain, improve urine flow, and prevent blockages.

Ureteral stents are commonly used to treat conditions such as kidney stones, ureteral strictures, and tumors that block the flow of urine. They can also be used to help manage urinary incontinence or to provide temporary relief for patients with chronic bladder problems.

Overall, ureteral stents are a valuable tool in the field of urology. They provide a safe and effective way to manage a variety of urinary tract conditions and can help improve the quality of life for many patients.
