Transition learning curve of a single surgeon performing ultrasound-guided modified lateral position percutaneous nephrolithotomy

Key Points

• To evaluate the learning curve of surgeons transitioning from fluoroscopy-guided to ultrasound-guided modified lateral PCNL.
• Analyzed performance of a single surgeon over 40 cases of ultrasound-guided modified lateral PCNL.
• Evaluated efficiency and precision in puncture during the procedures.
• Measured radiation exposure and safety outcomes.
• Surgeon achieved proficiency after approximately 40 cases.
• Notable improvements in efficiency and puncture precision were observed.
• Radiation exposure was significantly reduced without compromising safety or stone-free rates.
