Abstract:Flexible ureteroscopic lithotripsy is the main minimally invasive surgery in the treatment of ureteral calculi, with many advantages such as little trauma, short hospitalization time and low surgical risk. However, a large amount of perfusion fluid is required for irrigation during the surgery. The control of perfusion fluid was of great significance to ensure the clarity of the operative field, prevent surrounding urothelium and kidney tissue injury and postoperative infection. Therefore, this study has analyzed and summarized the problems related to perfusion fluid control, perfusion methods, and nursing progress in recent years.
