Abstract: ObjectiveTo compare the efficacy and safety of micropercutaneous nephrolithotomy and retrograde intrarenal surgery in holmium laser lithotripsy for lower renal calyx stones sized from 15 to 20 mm.
MethodsThe clinical data of 58 patients with lower calyx stones admitted from September 2016 to August 2017 were retrospectively analyzed. Of which, 31 cases were performed holmium laser lithotripsy of micropercutaneous nephrolithotomy as Microperc group, and 27 cases were carried out holmium laser lithotripsy of retrograde intrarenal surgery as RIRS group. The perioperative indexes， stone clearance rate and complications were compared between the two groups.ResultsThere were no statistical differences in the serum lever of calcitonin zymogen, the descent of hemoglobin, the blood transfusion rate, postoperative infection and VAS score between the two groups (P>0.05). The operative time was shorter and the postoperative hospital stays duration was longer in the microperc group than those in the RIRS group, and the difference was statistically (P<0.05). The stonefree rate was 87.1% and 81.5% respectively in the microperc and the RIRS group, and no statistical difference was found between the two groups (P>0.05).ConclusionThe micropercutaneous nephroscopy can achieve the same effect of RIRS for inferior renal calyx calculi sized from 15 to 20 mm with higher stonefree rate and lower complication rate, which would be one of the good selections.
