Article Abstract
Background: To demonstrate the technical feasibility of percutaneous nephrolithotomy (PCNL) guided by 5G-powered robot-assisted teleultrasound diagnosis system (RTDS) in a complex kidney-stone (CKS) cohort and present our preliminary outcomes. PCNL is highly skill-required, which hinders it popularization in primary medical units of remote regions. We designed an innovative tele-assistance approach to make PCNL easy to be operated by inexperienced surgeons.
Methods: This was a prospective proof-of-concept study (IDEAL phase 1) on intraoperative tele-assistance provided by online urological experts via a 5G-powered RTDS. Total 15 CKS patients accepted this technology. Online experts manipulated a simulated probe to assist unskilled local operators by driving a patient-side robot-probe to guide and monitor the steps of access establishment and finding residual stones.
Results: Median total delay was 177ms despite one-way network-connecting distance > 5,800 km. No perceptible delay of audio-visual communication, driving robot-arm or dynamic ultrasound images was fed back. Successful tele-assistance was obtained in all cases. The first-puncture access-success rate was 78.6% with a one-session SF rate of 71.3% and without complications of grade III-V.
Conclusions: The current technology based on 5G-powered RTDS can provide high-quality intraoperative tele-assistance, which has preliminarily shown satisfactory outcomes and reliable safety. It will break down a personal competence-based barrier to endow PCNL with more popular utilization.
Trial Registration: The study was approved by ethics committee of the Xinjiang Kezhou People's Hospital and ethics committee of the First Affiliated Hospital of Nanjing Medical University and was registered on http://www.chictr.org.cn (ChiCTR2200065849, 16/11/2022).

This case underscores the importance of meticulous imaging and procedural vigilance during PCNL to prevent rare complications such as IVC penetration. A prompt multidisciplinary response and careful catheter repositioning ensured a favorable outcome, highlighting strategies to safely manage unexpected vascular injuries during urological procedures.

Objectives: To report outcomes of complete ultrasound-guided percutaneous nephrolithotomy (PCNL) for horseshoe kidney (HSK) stones at a high-volume center and evaluate a novel technique (Needle-perc-assisted endoscopic surgery, NAES) for these patients.
Patients And Methods: We retrospectively reviewed all HSK stone patients who underwent PCNL at our institution over a 10-year period. The NAES technique was utilized during the most recent 4 years.

Introduction: Achieving stone-free status (SFS) is a key goal of endourological treatment, yet definitions of SFS and clinically insignificant residual fragments (CIRF) remain controversial. While CIRF is frequently defined as residual fragments ≤4 mm, there is no consensus on its clinical significance regarding complications and re-intervention needs. We evaluate the risk of complications and the need for re-intervention associated with the presence of CIRF following endourological treatment for urolithiasis.
