Percutaneous nephrolithotomy
Endoscopic combined intrarenal surgery
the standard-PCNL group (will be performed by urologists with more than 2 years of experience of PCNL), Fluoroscopic-guided percutaneous renal access will be done for patients in the prone position.
the ECIRS group (will be performed by urologists with more than 2 years of experience of PCNL and RIRS), patients will be oriented in the GMSV position.flexible ureteroscope will be inserted through the access sheath to observe the stone distributions. Under the guidance of fluoroscopy and endoscopic vision, a 18-20 Fr percutaneous tract will be established using sequential fascial dilators and a matching sheath for stone manipulation simultaneously. We use a 12-F nephroscope (Karl Storz).
