Application of Three-dimensional Visualization assisted Ultrasound for Percutaneous Renal Puncture

We present here the three-dimensional (3D) visualization fused with ultrasound and to evaluate its clinical application effect preliminarily. One hundred and eighteen patients with renal calculi in our hospital from September 2017 to December 2019 were prospectively randomized into two groups. The experimental group was treated with percutaneous renal puncture guided by the 3D visualization fused with ultrasound. The control group was treated with percutaneous renal puncture guided by B-ultrasonography (B-US). The puncture time, operation time, and the loss of hemoglobin in the experimental group were lower than those in the control group, and the success rate of establishing the channel at one time, and the coincidence rate between the channel and the longitudinal axis of the target renal calyx were higher. The stone clearance rate in the experimental group was higher, while the postoperative blood transfusion rate and interventional embolization rate in the experimental group were significantly lower. The difference was statistically significant ( P  < 0.05). 3D visualization assisted ultrasound could preliminarily guide precise navigation to puncture tissues, reduced operation time and bleeding, improved stone clearance rate and operation safety.
