Surgical treatment-

Surgery is offered to patients with kidney stones that are too large to pass on their own or because they reason too much pain not controlled with medications. If there is kidney function failure, any signs of infection or a single kidney then emergency surgery to decompress the kidney is necessary.

Ureteroscopy is a minimally invasive operation to treat kidney stones in the ureter. The surgeon passes a slight lighted tube (ureteroscope) equipped with a camera through the urethra and bladder to the ureter. Once the stone is located, laser is used to break the stone into small pieces, and stone fragments are removed with a special basket. Your doctor may then place a small tube (stent) in the ureter to relieve swelling and promote healing. You may need general or spinal anesthesia during this procedure.Recovery is rapid, and you should be capable to leave hospital and return to work in 1-2 days.
