Clinically, it is important to know not only if you have a stone, but also the size, number, location, and cause of the stone. In general, 90% of stones less than 0.5 cm in diameter can be expelled spontaneously. When stones are larger than 0.8 cm in diameter, surgical intervention is required. Currently, all patients with urinary stones do not require open surgery for stone extraction. Extracorporeal shock wave lithotripsy is preferred, and minimally invasive treatment can be implemented by intracorporeal intervention for larger, multiple, or complex kidney stones, or for ureteral stones with adhesive obstruction, as well as for larger bladder stones. For example, transurethral giant bladder stone lithotripsy for stone extraction, transurethral ureteroscopic lithotripsy for stone extraction, and percutaneous nephrolithotripsy for stone extraction can be performed using combined pneumatic ballast/ultrasound lithotriptor and laser lithotriptor to crush and remove stones with less trauma, less pain, and shorter hospital stay.
