Comparison of contrast-enhanced ultrasound versus conventional ultrasound-guided percutaneous nephrolithotomy in patients with nondilated collecting system: a randomized controlled trial.

Eur Radiol 2021 Feb 26. Epub 2021 Feb 26.

Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430030, China.

Objective: To compare the safety, effectiveness, and feasibility of contrast-enhanced ultrasound (CEUS) versus conventional ultrasound-guided percutaneous nephrolithotomy (PCNL) in patients with nondilated collecting system.

Methods: Between July 2018 and July 2020, 160 kidney stone patients with nondilated collecting system planned for PCNL were randomly assigned into two groups, CEUS with retrograde ureteral contrast injection and conventional ultrasound with retrograde ureteral normal saline injection. Patient's demographics, the success rate of puncture, success rate of a single-needle puncture, number of punctures, puncture time, perioperative outcomes, stone-free rate, and incidence of complications were compared.

Assessment of the Contrast-Enhanced Ultrasound in Percutaneous Nephrolithotomy for the Treatment of Patients with Nondilated Collecting System.

J Endourol 2021 Apr 30;35(4):436-443. Epub 2020 Oct 30.

Department of Urology, The Second People's Hospital of China Three Gorges University, The Second People's Hospital of Yichang, Yichang, China.

To investigate the clinical value of contrast-enhanced ultrasound (CEUS) in percutaneous nephrolithotomy (PCNL) for kidney stone patients without hydronephrosis. Patients with nondilated collecting system kidney stones who underwent PCNL between October 2018 and December 2019 at our hospital were enrolled in this study. Patients who met the inclusion criteria were randomized into two groups: a CEUS-guided PCNL group and a conventional ultrasound (US)-guided PCNL group. Read More

[Percutaneous renal access for percutaneous nephrolithotomy guided by contrast enhanced ultrasound: a single-center preliminary experience in China].

Beijing Da Xue Xue Bao Yi Xue Ban 2017 Dec;49(6):1071-1075

Department of Urology, Peking University First Hospital; Institute of Urology, Peking University; National Urological Cancer Center, Beijing 100034, China.

Objective: Contrast enhanced ultrasound (CEUS) is an innovative technique that employs microbubble contrast agents to demonstrate parenchymal perfusion. Ultrasound contrast agent was reported to be directly used in human internal lumen to improve the observation capacity of ultrasound. However, CEUS has never been reported to be used in the guidance of percutaneous renal access in percutaneous nephrolithotomy (PCNL). Read More
