Backgrounds: Renal stone is a common pathology in Vietnam. Open operations for the treatment of renal stone are widely applied at all hospitals. But the rate of residual stone post-operatively is still high. \r\n', u'Objective: To research the results of open operation to treat complicated renal stones at Hai Phong \u2013 Viet Tiep Hospital.\r\n', u'Methods: From May 2005 to November 2006, this retrospective study was carried out on 56 patients, who had open operations for the treatment of renal stone at Viet Tiep hospital.\r\n', u'Results: The rate of complicated renal stones is 44.7%. All renal stones cases are caused by hydronephrosis in different levels (from level 1 to level 4). Most of the cases were performed on with the parenchyma pyelonephritis opened method of Turner Warwick combined with controlling selective renal artery (39.3%). This technique has helped to save blood transmission during surgery, has more time to remove the stone, stop blood and restore better renal parenchyma. The rate of post-operative residual stones is also higher (55.4%). \r\n', u'Conclusion: Must indicate and choose the exact surgical techniques for limiting the complications. The operating investigations may reduce the rate of residual stones. \r\n', u'
