Brief Summary

Percutaneous nephrolithotomy(PCNL) is a surgical method for upper urinary calculi.Traditional percutaneous nephrolithotomy usually requires the lithotripsy with the left hand holding the nephroscope and the right hand adjusting the laser fiber,which requires a lot of practice to master this technique.The goal of this study is to explore the safety and effectiveness of the PCNL with one-handed lithotripsy technique

Outcome Measures

Primary Outcomes (4)

  • Operative time

    From the completion of anesthesia to the end of the suture incision.

    during the procedure

  • Stone clearance rate

    Preoperative and postoperative stone dimensions are compared by radiological assessment. Postoperative residual calculi \< 4 mm in diameter reflect complete removal of calculi (stone-free rate = 100%)

    Day 2 after the surgery

  • Renal pelvis mucosal injury rate

    Number of accidental injuries of renal pelvis mucosa during operation

    during the procedure

  • Changes in renal bleeding after surgery

    Pre- vs. post-operative difference in hemoglobin and hematocrit values

    Hour 3 after the surgery

Secondary Outcomes (2)

  • Hospital costs

    immediately after the discharge

  • Hospital stay

    immediately after the discharge

Study Arms (2)

Experimental group(group 1)

EXPERIMENTAL

Percutaneous nephrolithotripsy was performed using one - hand lithotripsy

Procedure: one-handed technique

Control group(group 2)

NO INTERVENTION

Percutaneous nephrolithotripsy was performed using traditional techniques

Interventions

Traditional percutaneous nephrolithotripsy usually requires the left hand to hold the nephroscope and the right hand to control the fiber for lithotripsy.Our intervention is to control the depth and direction of the sheath with the left hand, the nephroscope in the right hand and control the fiber optic lithotripsy
