A ureteral stent, also called a ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of urine flow from the kidney. The length of stents used in adult patients varies between 24 and 30 centimeters, and stents come in differing diameters, or gauges, to fit different sized ureters. The stent is usually inserted with the aid of a cystoscope, and one or both ends of the stent may be coiled to prevent it from moving out of place, a design known as a JJ stent, double J stent, or pig tail stent.
Facts
FAQs
Does a ureteral stent cause symptoms?
Yes. A 1520 patient study found urinary frequency and urgency were common early on.
It can. A clinical study of 1520 adults with stents found that unpleasant symptoms caused by the stent were encountered more frequently at 7 days after insertion, in terms of urinary frequency, dysuria, urgency and visible blood in the urine. Anyone with a stent who has concerns should speak with their urology team, because this atlas records what is known and does not give medical advice.
