Ureteroscopy with laser lithotripsy is used for stones located in the ureter. The ureteroscope is inserted in the urethra, passed through the bladde, and into the ureter. The stones are visualized, then fragmented with laser energy, and removed through the urethra. No incisions are made, although the patient is asleep for the procedure. Stones in the bladder can be fragmented and removed without an incision, except in cases where the stones are exceptionally large.
Surgical removal is safest and most efficient for large bladder stones.
