摘　　要：目的:研究不同大小输尿管软镜对肾内压的影响。方法:在10例带有肾造瘘管患者中,使用F12/14输尿管软镜通道鞘和150cmH_2O灌注压,监测4种不同型号输尿管软镜(Olympus URF-P5、Olympus URF-V、Karl Storz Flex-X^2、Karl Storz Flex-Xc)肾内压,并记录其结果。结果:Olympus URF-P5、Olympus URF-V、Karl Storz Flex-X^2、Karl Storz Flex-Xc四种软镜的肾内压分别为(19.02±2.995)cmH_2O、(27.93±4.401)cm H_2O、(20.62±3.763)cmH_2O及(19.68±3.293)cmH_2O。Olympus URF-V肾内压显著高于其他3种软镜(P<0.01),而其他3种软镜之间的肾内压差异无统计学意义(P>0.05)。结论:相同口径输尿管软镜通道鞘,输尿管软镜的大小是影响肾内压的一个重要因素,使用直径较粗的输尿管软镜时应注意防止术中肾盂高压。Objective：To investigate the effect of different size flexible ureteroscopes on intrarenal pressure.Method：F12/14 ureteral access sheath was used for ten patients with nephrostomy tube,and the irrigation pressure was 150cmH_2O.Intrarenal pressure in response to four different types of flexible ureteroscopes（Olympus URFP5,Olympus URF-V,Karl Storz Flex-X^2,Karl Storz Flex-Xc）were measured,and the results were analyzed.Result：The average intrarenal pressure caused by Olympus URF-P5,Olympus URF-V,Karl Storz Flex-X^2 and Karl Storz Flex-Xc were（19.02±2.995）cmH_2O,（27.93±4.401）cmH2O,（20.62±3.763）cmH_2O and（19.68±3.293）cm H_2O, respectively. Flexible ureteroscope of Olympus URF-V caused higher pressure than the other three kinds of flexible ureteroscopes（P 0.01）.However,no significant difference was seen among the other three kinds of flexible ureteroscopes（P 0.05）.Conclusion：When the same size ureteral access sheaths are used,the terminal size of flexible ureteroscope is an important factor influencing intrarenal pressure.It is necessary to avoid high intrarenal pressure when a thick flexible ureteroscope is used.
