Most patients will experience some side-effects from a ureteric stent. It is extremely safe but often irritates the bladder resulting in urinary frequency, visible blood in the urine and sometimes a burning sensation when passing urine. Patients can also experience discomfort or pain in the region of the kidney from a stent – this is usually short lasting at the time of bladder emptying and for a couple of minutes later. Many patients report that they feel as if they have a urinary tract infection when they have a stent in the ureter. Although it may feel like this, more often a urine test will reveal blood in the urine (which is normal with a stent) but no actual infection.
