Objectives @@@ To evaluate the effect of real-time three-dimensional (3D) ultrasonography (US) in guiding percutaneous nephrostomy (PCN). @@@ Materials and Methods @@@ 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. @@@ Results @@@ 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. @@@ Conclusions @@@ 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.
