When kidney stones don’t pass out with medication, surgery is the next option. One such surgery involves breaking up the kidney stones within the kidney by blasts or shockwaves from a laser. However, the biggest pieces can sometimes still remain intact. Even if you pee out the broken-up stones, it can feel like you are peeing out “shards of glass.”

In some cases, a stent is put inside the ureter to open the way from the kidney to the bladder. The stent can remain in for two weeks, or more or less. Ureteral stents are tubes made of plastic that are 10 to 15 inches (25 to 38 cm) long and are put through the urethra all the way to the kidney to let urine flow back to the bladder.

In many cases where kidney stones were removed, a ureteral stent is used to keep the ureter from becoming blocked again by swelling after kidney stone removal surgery. The stent is inserted when the patient is heavily sedated, but the patient remains awake and conscious when it is removed.
