Quick Answer

Kidney surgery to place a ureteral stent involves putting the patient under general anesthesia, putting a ureteroscope into the bladder through the urethra, using a flexible guide wire to place the stent into place, guaranteeing the stent is in the proper place then removing the guide wire.

Full Answer

A stent is a hollow tube that helps urine pass from the kidney to the bladder in patients having difficulty with urination due to kidney stones, cancer or stricture, states OSU Urology. If long-term use is necessary, the doctor changes the stent regularly to prevent stone formation or difficulty with removal. While the stent is in place, the patient may experience urinary frequency or urgency along with mild pain or irritation. It is also normal for patients to experience some bleeding with urination while the stent is in place, especially in the first few days.

Most patients can tolerate stent removal with the use of topical anesthesia, but some patients may require general anesthesia for the procedure. Patients typically do not have pain after stent removal, but the doctor may recommend use of pain medicine before and after to prevent pain, advises OSU Urology.
