ABSTRACT
Objective To investigate the risk factors and countermeasure of residual stones after single‐channel percutaneous nephrolithotomy for higher stone‐free rate and better operation result .Methods All patients who underwent single‐channel percu‐taneous nephrolithotomy in our hospital from June 2011 to December 2013 were retrospected and the cause of residual stones were analyzed .Results There were 42 patients who had residual stones after operation among total 262 patients undergone single‐chan‐nel PCNL .21 patients had residual stones because the stones they burdened were too complex .7 patients were concerned with com‐plications such as intraoperative hemorrhage .The stone fragments scattered into the calices in 7 patients with overlarge stone during fragmentation .The other causes concerned with stone residue included anatomic structural abnormalities of the kidneys(3 patients) , operation itself inherent limitations(3 patients) ,insufficient practice and experience in operation(1 patients) .Conclusion The main causes concerned with residual stones of single‐channel PCNL are complexity of urinary calculi ,bleeding ,scattering of stone frag‐ments and anatomic structural abnormalities of the kidney .
