Percutaneous nephrolithotomy (PCNL) has completely replaced traditional open stone extraction as an advanced method for the treatment of kidney stones and upper ureteral stones. Through a combination of percutaneous nephrolithotomy, ureteroscopic stone extraction and extracorporeal shock wave lithotripsy, almost all renal ureteral stones can be eliminated from open surgery. Percutaneous nephrolithotomy is a procedure in which a 0.5-1 cm channel is manually punctured and dilated on the surface of the kidney, a stone is found under direct vision with an endoscope, and the stone is crushed and removed with pneumatic ballast or laser, or the pelvic ureteral junction is incised and dilated. Most PNLs can be performed in one stage, i.e., the stones are crushed and removed in one operation, which has the advantage of one operation, one anesthesia, less pain and shorter hospital stay. The disadvantages are bleeding and poor visualization. It is suitable for: those with combined infection and post-renal insufficiency; those with bleeding tendency; those with serious bleeding in the first stage operation; those with residual stones after the first stage or open surgery; the advantage is that the sinus tract has been formed, less bleeding and clear vision. The second stage of surgery can be performed without anesthesia. Minimally invasive percutaneous nephrological technique (MPCNL) is a modified percutaneous nephrological method to reduce the diameter of the nephrostomy channel and remove the stone by ureteroscopy. The specific type of procedure to be adopted is decided by the surgeon according to the condition and intraoperative situation. Ureteroscopy is an endoscope that is placed through the natural body channel such as the urethral bladder to perform various operations such as ureteral and intrarenal tissue biopsy, lithotripsy, electrocautery and endoureteral stenosis incision. It is mainly used to treat stones, polyps or strictures in the middle and lower ureter, and can also be used to diagnose diseases such as renal pelvis and ureteral tumors; there are two types of ureteroscopes: rigid ureteroscope and soft ureteroscope. Ureteroscopy has been favored by physicians and patients for its non-incisional, less invasive and faster recovery procedures, and has played an increasing role in the treatment of ureteral diseases, especially ureteral stones. Ureteral double J tubes are usually left in place after percutaneous nephrolithoscopy and ureteroscopy, and usually need to be removed after 4-6 weeks by appointment at the outpatient clinic. We have one set of German Wolf nephroscope and one set of ureteroscope, and a new set of ureteroscope, which can greatly solve the problem of residual stone after percutaneous nephroscopy, and a high-power holmium laser. We perform percutaneous nephrological and ureteroscopic surgery nearly 500 times a year, with strong technical force and rich clinical experience.
