Urologic stones include: kidney stones, ureteral stones and bladder stones, etc. They are common and frequent diseases in urology surgery, especially in Daqing area, where the incidence of urologic stones is relatively high, and they are the most common diseases in urology surgery. In recent years, the treatment of stones has made great progress, gradually completing the transition from open surgery to minimally invasive surgery. The Department of Urology of Daqing Oilfield General Hospital has various treatment methods for stones, including: percutaneous nephrolithotomy with holmium laser lithotripsy, transureteroscopic holmium laser or pneumatic ballistic lithotripsy, holmium laser lithotripsy for bladder stones and other minimally invasive stone treatment methods. Chen Guoqiang, Department of Urology, Daqing Oilfield General Hospital (a) transureteroscopic holmium laser or pneumatic ballistic lithotripsy: ureteral stones have been treated with open ureterotomy, which is traumatic, slow to recover, and prone to ureteral stenosis; in recent years, we have carried out transureteroscopic pneumatic ballistic and holmium laser lithotripsy, treating more than 400 cases of ureteral stones every year. Patients with ureteral stones do not need incision, but the ureteroscope is inserted through the urethra and bladder to reach the stone stagnation site, and the pneumatic ballistic or holmium laser is applied to crush the stone, avoiding incision, with little trauma and quick recovery, and most of the patients can be discharged from the hospital in 2-4 days after the operation. （Holmium laser treatment for bladder stones: bladder stones are usually treated by open surgery, and only smaller bladder stones are treated by pneumatic ballistic lithotripsy, which is traumatizing, slow in recovery and prone to incision infection. In 2008, holmium laser was introduced into our hospital, and the application of transurethral holmium laser lithotripsy for bladder stones has become the preferred method of treatment of bladder stones in our department, and more than 100 cases of bladder stones are treated with holmium laser every year, with no damage to the bladder mucosa or bladder perforation, and a clear field of vision, which can break both small and large stones. No bladder mucous membrane damage, no bladder perforation, clear vision, no matter small or big stones can be broken, no need for bladder irrigation after operation, you can be discharged from the hospital on the second day after the operation, which is really minimally invasive and non-invasive treatment of bladder stones. (C) Holmium laser lithotripsy with percutaneous nephrolithotripsy for complex kidney stones: small kidney stones can be treated with extracorporeal shock wave lithotripsy, but larger kidney stones and complex kidney stones can be extracted by nephrectomy, but the risk of the surgery is high, and many patients end up with nephrectomy. In recent years, our hospital started to carry out percutaneous nephrolithotripsy for complex kidney stones, especially after the introduction of holmium laser, we carried out percutaneous nephrolithotripsy holmium laser lithotripsy for complex kidney stones in more than 200 cases, and it has become the first choice of our department to treat complex kidney stones, which is the gold standard for the treatment of complex kidney stones with its small damage, small impact on renal function, high rate of stone removal, and repeatability of operation. Our department of urology has carried out various minimally invasive treatments for urinary stones, and they are widely used in clinic, and have become the routine methods for treating urinary stones in our hospital, and the level of minimally invasive treatment of stones has reached the advanced level in the province, and minimally invasive surgical methods such as ureteroscopic pneumatic ballistic lithotripsy, holmium laser lithotripsy, percutaneous nephrolithotripsy holmium laser lithotripsy, transurethral bladder stone holmium laser lithotripsy, etc., together with extracorporeal shock wave lithotripsy, have been used in 800-1000 cases every year in the treatment of urinary system stones. The number of cases of urolithiasis is 800-1000 per year, and more than 95 cases of urolithiasis can be cured by minimally invasive treatments without incisions, which brings real benefits to the majority of patients.
