Clinical observation: In recent years, the incidence of children’s urinary stones is still significantly higher than before, since 2010, the Department of Urology of Hebei Children’s Hospital has completed more than 300 cases of minimally invasive treatment of urinary stones, more than 95% of kidney stones and more than 90% of ureteral stones, the use of general anesthesia with extracorporeal shock wave lithotripsy, successfully solved the majority of the upper urinary tract stones in clinical treatment of the difficult problem, to save a lot of emergency, critical, The patients have been saved many children with acute, critical and severe stones. Through the treatment and clinical observation of a large sample of cases, it has been proved that the efficacy of extracorporeal shock wave lithotripsy in the treatment of pediatric upper urinary tract stones is exact, the trauma is small, and the chances of fatal complications such as hemorrhage and urogenital septicemia occurring in the perioperative period are extremely low. Follow-up observation of the children’s renal function and renal morphology did not show any abnormality, and no complications occurred. Due to the short formation time of pediatric urinary stones, most of the stones are simple in composition and morphology, and the thin body tissues are favorable for extracorporeal shock wave localization and lithotripsy, extracorporeal shock wave lithotripsy, as the only non-invasive surgical treatment, still has an irreplaceable role. In recent years, with the continuous innovation of intracavitary lithotripsy instruments and laser equipment, holmium ureteroscopic lithotripsy has gradually become a new trend in the treatment of children’s upper urinary tract stones, with more and more extensive clinical use, and has replaced extracorporeal shock wave lithotripsy as the first choice of treatment for children’s upper urinary tract stones in some countries in Europe and the United States. For the treatment of complex upper urinary tract stones in children, a single treatment is often ineffective. While infrarenal calyceal stones due to anatomical anomalies may be the shortcoming of flexible ureteroscopy, the combination of the two can successfully manage complex upper urinary tract stones in children, highlighting the advantages of combined treatment. For cast stones and multiple stones, we firstly use holmium laser in ureteroscopy to pulverize the larger stones in the renal pelvis or ureter, and use extracorporeal shock wave lithotripsy for calyceal stones that cannot be entered into the scope or residual intracavitary lithotripsy, which gives full play to the advanced performances of different lithotripsy instruments and equipments, and not only reduces the psychological pressure of the operator, but also reduces the number of surgeries, reduces the risk of surgeries, saves the medical cost, and improves the compliance of treatment. treatment compliance. Ureteroscopic holmium laser lithotripsy and extracorporeal shock wave lithotripsy are the safest and most effective treatments for children’s upper urinary tract stones, and ureteroscopic holmium laser lithotripsy combined with extracorporeal shock wave lithotripsy is highly effective in treating children’s complex upper urinary tract stones, providing a new way of thinking and method of treatment for children’s complex upper urinary tract stones.
