partial staghorn renal calculi
Brief summary
The goal of this clinical trial is to learn if flexible and navigable suction ureteral access sheath combined with needle perc works to treat partial staghorn renal calculi. It will also learn about the safety of drug ABC. The main questions it aims to answer are: * Does flexible and navigable suction ureteral access sheath combined with needle perc result in similar stone free rate compared with PCNL * Does flexible and navigable suction ureteral access sheath combined with needle perc result in more complications compared with PCNL Researchers will compare flexible and navigable suction ureteral access sheath combined with needle perc result in similar stone free rate compared with PCNL to see if flexible and navigable suction ureteral access sheath combined with needle perc works to treat partial staghorn renal calculi. Participants will: * Performed flexible and navigable suction ureteral access sheath combined with needle perc or PCNL * Visit the clinic after surgery 1 month and 3 month for checkups and tests
