- StmPNL Group: single tract minimally invasive percutaneous nephroscopy in prone position was performed for the patients in the prone position
- StmECIRS Group: single tract minimally invasive endoscopic combined intrarenal surgery was performed in the improved prone frog split-leg position
- Hb: Hemoglobin; Scr: serum creatinine
- aMann–Whitney U test was used when normal distribution was not obeyed
- bNon-normally distributed continuous variables were represented by the median (quartile)
- cSince the data frequency contains “0”, the result of Fisher's Exact Test in the Chi-square Test was used
