Usefulness of real‐time three‐dimensional ultrasonography in percutaneous nephrostomy: an animal study

Objective: The objective of this study is to compare the outcome of percutaneous nephrostomy by ultrasound (US) versus fluoroscopy including access time, volume of anesthesia required, success rate, and complications. Methods: One hundred patients were enrolled in a prospective randomized study. Patients were divided into two groups, 50 cases each. Comparing the two groups was done regarding the need for dye, radiation effect, time taken, trial number, rate of complication, volume of anesthesia, and success rate. Results: Patient demographics were comparable between both groups with no statistically significant difference. According to the modified Clavien–Dindo classification, the complications were Grade I (pain and mild hematuria) in each group. Procedural pain was present in 41 (82%) patients in Group I and in 48 (96%) patients in Group II. It was treated in both groups with a simple analgesic. Mild hematuria was present in 5 (10%) patients in the US group and 13 (26%) in the fluoroscopic group and treated by hemostatic drugs only. There was a statistically significant difference between both groups regarding the volume of required local anesthesia, the trial numbers, the puncture numbers, bleeding, extravasation, and change in the hemoglobin level. Conclusion: US percutaneous renal access is a safe and effective modality with a high success rate, less operative time, and complication rate. However, a minimum of 50 cases with some pelvicalyceal system dilation may be preliminary requisites to achieve good orientation and competence in achieving safe US percutaneous renal access for future endourological procedures.

Usefulness of real‐time three‐dimensional ultrasonography in percutaneous nephrostomy: an animal study

Abstract: 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.
