药物成份或治疗方案详述: |
使用一种输尿管导管作为辅助冲洗的微导管,并将其引入输尿管镜的内腔,通过微导管导管加压注入26℃0.9%NaCl溶液,液体通过输尿管镜内腔与微导管之间的间隙回流出输尿管镜,形成连续冲洗。通过实验模型,在液体灌注压强分别为150mmHg、200mmHg、450mmHg、人工自由推注的不同条件下,测定钬激光输出功率在0.6J×20Hz、0.8J×20Hz、1.0J×20Hz情况下,模拟经输尿管镜输尿管碎石过程中碎石区域温度及压力变化。得到能保持局部温度低于43度,压力低于20mmHg(27cmH2O)的微导管型号和灌注条件。采用研究结果所推荐的微导管型号及灌注条件进行临床研究,观察临床应用效果。 |

Description for medicine or protocol of treatment in detail: |
A ureteral catheter was used as a microcatheter to assist flushing, and it was introduced into the lumen of the ureteroscope. The microcatheter was pressurized to inject 0.9% NaCl solution at 26 ° C. The liquid flowed back out of the ureteroscope through the gap between the lumen of the ureteroscope and the microcatheter to form a continuous flushing. Through the experimental model, under different conditions of liquid perfusion pressure of 150mmHg, 200mmHg, 450mmHg, and artificial free perfusion, the output power of holmium laser was measured at 0.6J × 20Hz, 0.8J × 20Hz, and 1.0J × 20Hz. The temperature and pressure changes in the gravel area during ureteroscopic ureteral lithotripsy were simulated. The microcatheter model and perfusion conditions that can keep the local temperature below 43 degrees and the pressure below 20mmHg (27cmH2O) were obtained. The microcatheter model and perfusion conditions recommended by the research results were used for clinical research to observe the clinical application effect. |
