Abstract Objective To investigate the method and safety of percutaneous nephrolithotomy(PCNL)with renal access created by modified B ultrasound guided two-step dilation in the treatment of non-hydronephrosis renal calculus,and to evaluate its clinical value.Methods From January to December in 2016,80 patients with non-hydronephrosis renal calculus in our hospital were selected and randomly divided into group A and group B,40 cases in each group.Group A was treated with PCNL with renal access created by modified B ultrasound guided two-step dilation,group B was treated with PCNL with conventional B ultrasound guided gradual dilation.The success rate of renal access,renal access creation time,operation time,the average blood loss,hospitalization time,the calculus clearance rate and the incidence rate of complications between the two groups were analyzed and compared respectively.Results There was no significant difference between A group and B group in the stone clearance rate and hospital stay(P＞0.05).The success rate of group A was higher than that of group B,channel establishment time,operation time of group A was shorter than that group B, the blood loss of group A was less than of group B,with significant difference(P＜0.05).There was no significant difference in the incidence rate of complications between the two groups(P＞0.05).Conclusion PCNL with renal access created by modified B ultrasound guided two-step dilation in the treatment of non-hydronephrosis renal calculus is safe and feasible,the effect is significant,it has some advantages of simple channel,high success rate,shorter operation time and less bleeding,it is worthy of promotion.
