Abstract Objective To compare the efficacy of two pathways of percutaneous nephrolithotomy (PCNL) in the treatment of complex lower calyceal calculi. Methods The clinical data on 258 cases of complicated lower calyceal calculi treated with PCNL between October 2015 and October 2020 in the Department of Urology at our hospital was retrospectively analyzed. According to the puncture pathway, the patients were divided into the upper calyx group and lower calyx group. The difference in efficacy between the two pathways of PCNL was studied in terms of duration of surgery,complete stone clearance rates and intraoperative and postoperative complications. Results All the patients had their access established in phase I. The stone clearance rate of upper calyces (85.92%) was significantly higher than that of lower calyces (59.62%). The duration of surgery was (74.69±2.94) min in the upper calyx group and (84.50±15.25) min in the lower calyx group. The incidence of postoperative complications was 6.31% in the upper calyx group and 32.69% in the lower calyx group. The decrease of hemoglobin was (13.10±0.60) g/L in the upper calyx group and (14.60±0.30) g/L in the lower calyx group.The difference was statistically significant (P<0.05). The incidence of bleeding and infections in the upper calyx group was significantly lower than in the lower calyces. Conclusions PCNL for complex lower calyceal calculi via the upper calyceal pathway is safe and effective with a high stone clearance rate, less bleeding and shorter duration of surgery.
