Objective:To investigate the clinical efficacy of treating complex renal calculus by standard channel combined with micro channel percutaneous nephrolithotomy (MPCNL). Methods:Seventy-six patients with complex renal calculus in our hospital between January, 2012 to December,2012 were selected and randomly divided into big-tract group and double-tract group. There were 38 cases in big-tract group, they were treated with traditional big channel percutaneous nephrolithotomy percutaneous nephrolithotomy (PCNL). There were 38 cases in double-tract group, they were treated with standard tract combined with MPCNL. Operation time, bleeding during operation,stone clearance rate I phase,complications, ambulation time,hospitalization time, wound healing time, time of renal function recovery of two groups were compared. Results:The operation time,bleeding during operation of double-tract group were significantly less than those of big-tract group (P<0.05); the stone clearance rate I phase of double-tract group was significantly higher than that of big-tract group (P<0.05), and the complications were significantly less than big-tract group (P<0.05); the ambulation time, hospitalization time, wound healing time, time of renal function recovery of double-tract group were significantly shorter than those of big-tract group (P<0.05). Conclusion:Treating complex renal calculus by standard-tract PCNL combined with MPCNL has good effect, it can effectively reduce the residual stones and operation trauma, reduce complication risk, improve stone clearance rate and operation safety, it is worth to be spreading. |
