Abstract：Objective： To discuss the effect of percutaneous nephrolithotripsy （PCNL） under micro channel and standard channel on the stone removal and complications in elderly patients with renal calculi. Methods： A total of 120 elderly patients with renal calculi in our hospital from July 2017 to July 2019 were selected, and equally divided into micro channel group and standard channel group according to the random number table. The micro channel group was treated with PCNL via a micro channel, and the standard channel group was treated with PCNL via a standard channel. the stone removal effect, perioperative indexes, renal function [blood urea nitrogen （BUN） and serum creatinine （SCR）], inflammatory stress [C-reactive protein （CRP）, tumor necrosis factor-alpha （TNF-alpha）, interleukin-6 （IL-6）], and complications were compared between the two groups. Results： There was no significant difference in stone clearance rate between the micro channel group and the standard channel group （P > 0.05）. The operation time in the micro channel group was significantly longer than that in the standard channel group, the bleeding volume, time out of bed and time of hospitalization in the micro channel group were significantly reduced as compared with those in the standard channel group with the difference being statistically significant （P < 0.05）. The BUN, SCR, CRP, TNF-alpha and IL-6 in the micro channel group were significantly lower than those in the standard channel group with the difference being statistically significant （P < 0.05）. The incidence of complications in micro channel group was significantly lower than that in standard channel group （P < 0.05）. Conclusions： Compare with the standard channel, PCNL via the micro channel has the good stone removal effect in elderly patients with renal calculi, and it can effectively reduce the renal function damage and inflammatory stress response of patients, which is helpful to reduce the postoperative complications, and worth for further clinical promotion.
