Objective: The objective of this research was to examine the features and potential hazards of sedation in children of varying ages. Additionally, the study aimed to comprehend these variations to enhance the safety and efficacy of clinical applications.

Methods: A retrospective analysis was conducted on case data involving pediatric patients who underwent imaging procedures in outpatient settings and necessitated procedural sedation from 2022 to 2024.

Article Synopsis
  • Developed a nonbiohazardous simulator for ultrasound-guided percutaneous nephrolithotomy using expert feedback and modern education theory.
  • A prototype was created with realistic anatomical features through 3D printing and hydrogel molding, and validated by expert surgeons and participants in multicenter trials.
  • The simulator showed high satisfaction ratings and significant skill improvements for residents, making it an effective training tool for urologic education.

We report the first multicenter, prospective, randomized noninferiority controlled trial of steerable ureteroscopic renal evacuation (SURE) for nephrolithiasis treatment. Candidates for laser lithotripsy ≥18 years with ≥1 renal stone ≥7 mm and 7-20 mm stone burden were randomized 1:1 SURE ureteroscopy (URS). SURE was performed using the CVAC Aspiration System, a novel steerable irrigation-aspiration catheter.

Fluctuating pH conditions can affect heavy metal mobility, thereby limiting the efficiency of biofiltration systems (BS). To address this, we developed an innovative rhizosphere sponge, biochar-based bioreactor (RBB), designed to stabilize Cd removal across a pH range of 5 to 9. RBB consistently outperformed the control, achieving a notable 91.

Postoperative infections after ureteroscopy are common and potentially devastating complications. National and international guidelines recommend treatment of symptomatic positive urine cultures prior to operation, but how to manage patients with asymptomatic colonization remains unclear. In clinical practice, there is wide variation in the choice and duration of antibiotics for these patients.
