In some cases, the urologist may place a stent in the ureter to promote healing and reduce swelling. A ureteral stent is a soft plastic tube with holes, temporarily inserted into a ureter to help drain urine into the bladder. One end goes into the kidney, and the other end goes into the bladder. A coil on each end keeps the stent in place. The stent can't be detected from outside the body. It should not interfere with your normal activities. The stents need to be removed and are not meant to be indwelling. Please consult your doctor and/or urologist if you have further questions regarding the duration of the stent.
