Abstract：Objective:To evaluate percutaneous nephrolithotomy (PCNL)combined with retrograde intrarenal surgery (RIRS)for residual stones after PCNL under a single position of lateral oblique lithotomy position.Meth-ods:From September 2016 to August 2017,16 cases of residual stones after I-stage PCNL were treated by PCNL combined with RIRS under a single position of lateral oblique lithotomy position (combined double-endoscope group),including7 males and 9 females with the mean age of 53.56 years.All the cases were found with staghorn calculi before operation,including 7 cases in the left side and 9 cases in the right side.The comparison was done between combined double-endoscope group and PCNL group.There were 1 6 cases in the PCNL group,including 8 males and 8 females with the mean age of 56.63 years.Results:All the procedures in both combined double-endo-scope group and PCNL group were completed successfully.The calculus clearance rate in combined double-endo-scope group was 93.8%,which was higher than that (31.3%)of PCNL group(P<0.05).There was no signifi-cant difference between the postoperative and preoperative mean haematoglobin [116.5 (85-148)g/L vs .124.5 (90-160)g/L]in combined double-endoscope group (P>0.05).There was no significant difference between the postop-erative and preoperative mean haematoglobin [107.4 (76-128)g/L vs .117.7 (79-151)g/L]in PCNL group (P>0.05).There was no significant difference in mean operative time and length of stay between combined double-endoscope group and PCNL group (P>0.05).Conclusions:PCNL combined with RIRS for residual stones after PCNL under a sin-gle position of lateral oblique lithotomy position is safe and efficient,with few puncture channels and high stone free rate.
