The purpose of this paper is to present our experience with real-time computed tomography (CT) fluoroscopy guided percutaneous nephrostomy (PNT) and to describe this technique involving puncture under laser guidance. We attempted 30 placements in 25 patients: puncture was directed by laser guidance and placement of the tube was made under real time CT fluoroscopy. 25 procedures were performed in prone position and 5 procedures in the supine position. The time necessary for the procedure ranged from 10 to 45 min (mean 25 min). The average duration of CT fluoroscopy per placement was 49 seconds (range 7-110 s). The PNT placement was successful as a sole procedure including puncture and catheter placement in 24 of 30 cases; in the remainder of cases, puncture was performed under CT guidance but the catheter was definitively positioned in conventional fluoroscopy. The CT fluoroscopy technique allows routine, efficient and safe PNT placement, especially when encountering difficult access to the pelvicaliceal system.
本文的目的是介绍我们在实时计算机断层扫描（CT）透视引导下经皮肾造瘘术（PNT）方面的经验，并描述这种在激光引导下进行穿刺的技术。我们对25例患者尝试了30次置管操作：穿刺由激光引导，导管放置在实时CT透视下进行。25例手术在俯卧位进行，5例在仰卧位进行。手术所需时间为10至45分钟（平均25分钟）。每次置管CT透视的平均持续时间为49秒（范围7至110秒）。在30例病例中，有24例PNT置管作为包括穿刺和导管放置的单一操作成功；在其余病例中，穿刺在CT引导下进行，但导管最终在传统透视下定位。CT透视技术允许常规、高效且安全地进行PNT置管，尤其是在遇到肾盂肾盏系统穿刺困难时。
