Removal of stones by ureteral cannula is a minimally invasive procedure that does not require an incision.
Removing stones from the urethra by ureteral cannulation involves inserting a ureteroscope into the ureter to locate the stones, where smaller stones are powdered using laser or ultrasound equipment, and the powdered stones will then flow into the bladder, while larger stones are added directly to the bladder using a lithotripsy forceps, and finally excreted in the urine. The whole process is done without incision, reducing the possibility of wound infection compared to surgical incision.
It is important to remain relaxed during the procedure of removing stones from the urethra by intubation, as excessive tension may cause increased pain.
After extubation, patients are generally advised to undergo regular kidney ultrasounds, as ureteral stones are a disease with a high recurrence rate, and it is best to undergo ultrasound checkups every six months to determine if the stone has recurred. If the stones recur , the next step of treatment is under the guidance of the doctor.
