Kidney stones are common and frequent diseases in urology. For large and complex kidney stones, open surgery has been used in the past. Open surgery, including pelvicotomy and parenchymalotomy, has the disadvantages of large surgical trauma, many complications, slow postoperative recovery, heavy tissue adhesions and high residual stone rate. In the past 4 years, all kidney stone surgeries have been performed with minimally invasive techniques. Our hospital is equipped with the internationally advanced EMS 4th generation pneumatic ballistic ultrasonic lithotripsy system, Olympus ureteroscope, high-power holmium laser and various holmium laser fibers. Minimally invasive kidney stone surgery includes percutaneous nephrolithotomy and holmium laser lithotripsy with ureteroscope. Percutaneous nephrolithotomy requires only a skin incision of less than 1 cm in the lumbar region to complete the procedure. During the procedure, ultrasound is used to locate the stone, a puncture needle is used to puncture into the target calyx, and a guide wire is used to gradually dilate the stone into the nephroscope, and an ultrasound probe or pneumatic ballistic or holmium laser lithotripsy is used to completely crush the stone and aspirate it. Holmium laser lithotripsy with ureteroscope is suitable for relatively small kidney stones (1cm-3cm) without any incision. The ureteroscope is passed through the urethra into the renal pelvis and calyces, the stone is found, and the stone is crushed by the Holmium laser fiber with a diameter of 200 um. The larger stones can be removed through the mesh basket, and the smaller stones can be discharged by themselves. Stones larger than 3 cm and complex stones can also be removed by Holmium laser with ureteroscopy. Minimally invasive surgery greatly improves the surgical results and minimizes surgical trauma while maximizing stone removal and avoiding the pain of open surgery. Therefore, minimally invasive surgical methods for kidney stones are increasingly popular among patients and doctors.
