Methods A total of 105 consecutive patients undergoing minimal PCNL by using the two-step dilation protocol （ Group I ） and step by step dilation protocol （ Group 1I ） were reviewed. Two groups were compared in terms of stone size, dilating time, operation time, and blood loss. Results In all patients, the dilating of channel was finished and the success rate was 100%. The stone-free rate was 88. 7% （47/53） in Group [ and84.6% （44/52） in Group O . There were significant differences in the time of dilating and the blood loss in dilating channel （P = O. 000）. But there was no significant difference in the operation time of PCNL. Conclusion PCNL of the urinary calculi is safe in Chinese patients. Two-step dilation in PCNL has advantages of shorter dilating time and lower blood loss in different types of calculi during dilating.展开更多
