To evaluate the effect of real-time three-dimensional (3D) ultrasonography (US) in guiding percutaneous nephrostomy (PCN).
A hydronephrosis model was devised in which the ureters of 16 beagles were obstructed. The beagles were divided equally into groups 1 and 2. In group 1, the PCN was performed using real-time 3D US guidance, while in group 2 the PCN was guided using two-dimensional (2D) US. Visualization of the needle tract, length of puncture time and number of puncture times were recorded for the two groups.
In group 1, score for visualization of the needle tract, length of puncture time and number of puncture times were 3, 7.3 ± 3.1 s and one time, respectively. In group 2, the respective results were 1.4 ± 0.5, 21.4 ± 5.8 s and 2.1 ± 0.6 times. The visualization of needle tract in group 1 was superior to that in group 2, and length of puncture time and number of puncture times were both lower in group 1 than in group 2.
Real-time 3D US-guided PCN is superior to 2D US-guided PCN in terms of visualization of needle tract and the targeted pelvicalyceal system, leading to quick puncture. Real-time 3D US-guided puncture of the kidney holds great promise for clinical implementation in PCN.
评估实时三维（3D）超声（US）引导经皮肾穿刺（PCN）的效果。
建立犬肾盂积水模型，梗阻 16 只比格犬的输尿管。将比格犬等分为两组，1 组采用实时 3D US 引导下 PCN，2 组采用二维（2D）US 引导下 PCN。记录两组的针道可视化、穿刺时间和穿刺次数。
1 组中，针道可视化评分、穿刺时间和穿刺次数分别为 3、7.3±3.1 s 和 1 次。2 组中，分别为 1.4±0.5、21.4±5.8 s 和 2.1±0.6 次。1 组针道可视化优于 2 组，穿刺时间和穿刺次数均低于 2 组。
实时 3D US 引导下 PCN 优于 2D US 引导下 PCN，在针道可视化和靶向肾盂系统方面具有优势，可实现快速穿刺。实时 3D US 引导肾脏穿刺在 PCN 临床应用中具有广阔的前景。
