[Intraoperative complications of endoscopic removal of stones from the upper urinary tract].

Using a large clinical material, retrospective analysis of the frequency, nature and causes of intraoperative complications occurring in the process of endoscopic removing stones from the upper urinary tract was performed. In 2008-2010 three trained surgeons with experience in endoscopic surgery of nephrolithiasis over 20 years performed 1027 operations in RSCU (Tashkent, Uzbekistan). The data were also compared with results of similar interventions which were performed by the same surgeons before 1997 during the development of the method.
