Record status
This record was last updated September 2, 2025 (before its estimated December 31, 2025 completion). Its status may not reflect the trial's current state.
Summary
The removal rate, complication risk and operation time of ureteral soft scope combined with negative pressure suction sheath therapy for patients with high-load kidney stones (2-3cm) are still controversial. Therefore, the safety and effectiveness of flexible ureteroscope combined with negative pressure suction sheath in treating patients with high-load kidney stones is unknown. This study will help to solve the problems, provide a more scientific treatment strategy for clinical practice, and promote the application of negative pressure aspiration technology in the field of flexible ureteroscopy lithotripsy, providing new means and ideas for individualized treatment.
