The dimensions shape, and material from the ureteral stent for use depends upon the patient's anatomy and also the reason that stent is needed. Most stents are 5-12 inches (12-30 cm) long, and also have a diameter of 0.06-0.2 inches 1.5-6 mm. Either ends from the stent might be coiled (known as a pigtail stent) to avoid it motionless unnatural; an open-ended stent is much better suited to patients who need short-lived drainage. Sometimes, one end from the stent includes a thread mounted on it that extends with the bladder and urethra towards the outside the body; this helps with stent elimination. The stent material should be bendable, durable, non-reactive, and radiopaque visible with an x-ray.
