Urological stones are the most common diseases in urology, and renal deerstalker stones are one of the more difficult ones to treat, with large stones, usually more than 3-4 cm in diameter, even occupying the whole kidney, and seriously affecting kidney function. This results in greater trauma, longer hospital stay, larger scars after surgery, and a higher recurrence rate. Since 2002, our center has been carrying out percutaneous nephrolithotomy (commonly known as “perforation”) to treat kidney stones, and now we have been using minimally invasive percutaneous nephrolithotomy to treat ordinary kidney stones, various kinds of huge kidney stones, full antler stones, and cases with high risk of open surgery; for patients with special kidney stones (such as stones with a history of open surgery and recurrence, kidney stones after transplantation, horseshoe kidney combined with kidney stones, repeat kidney stones, and isolated kidney stones), we have been using percutaneous nephrolithotomy to treat kidney stones. We also have rich clinical experience in the treatment of special kidney stone patients (such as recurrent stones with history of open surgery, post-transplant kidney stones, horseshoe kidney combined with kidney stones, duplicate kidney stones and isolated kidney stones, hunchback and children, etc.). So far, our center has completed more than 1000 cases of minimally invasive percutaneous nephrolithotomy, with a complete stone removal rate of more than 92%, minimal trauma, only a small hole about the thickness of a pencil in the waist, and the patient can get out of bed in 2-3 days after surgery, with little pain and quick recovery, the recent efficacy and long-term effect are better than traditional open surgery. The minimally invasive percutaneous nephrolithotomy has reached the leading level in the province. In the past 10 years, more than 90% of stone patients in our center can be treated with modern treatment methods, including: minimally invasive percutaneous nephrolithotomy (PCNL), ureteroscopic lithotripsy (URL), extracorporeal shock wave lithotripsy (ESWL), which is one of the very few medical units in the province that can truly replace traditional open surgery with modern treatment methods.
