Abstract 【Objective】To compare the effects of the standard single channel percutaneous nephrolithotomy (PCNL)and double channel percutaneous nephrolithotomy (PCNL) on renal hemodynamics. 【Methods】A total of 159 patients with kidney stones selected from June 2012 to June 2015 in our hospital was divided into a double channel group (N=77) and a single channel group (N=82). The patients of the double channel group were treated with the double channel PCNL and the patients of single channel group were treated with the single channel PCNL to observe the effects on renal hemodynamics of patients in the two groups before PCNL and after PCNL 30 days. 【Results】The operation time of the double channel group was significantly higher than that of the single channel group (P < 0.05); the bleeding amount and intraoperative rehydration amount of the double channel group were significantly lower than in the single channel group (P<0.05); After 30 days，Vmax and S / D of the renal artery，segmental artery，and interlobar artery was significantly higher than that of preopertative, and RI was significantly lower than that of preopertative (P<0.05). In the double channel group，Vmax and S / D of renal artery，segmental artery，interlobar artery was significantly higher than that of the single channel group; RI was significantly lower than that of the single channel group (P < 0.05). After the operation, GFR values were all significantly lower than before operation in both groups (P<0.05); the change of GFR values between preoperative and postoperative in the single channel group of patients was significantly greater than that of the double channel group (P<0.05). 【Conclusion】PCNL surgery has effects on renal hemodynamic to a degree. Because of less damage is caused on the blood vessels in the double channel PCNL process, the effects on the renal hemodynamic is smaller than that of the single channel PCNL.
