Abstract

Background and Objectives: This paper evaluates the efficacy and safety of ureteral access sheath (UAS) utilization in retrograde intrarenal surgery (RIRS). Materials and Methods: We searched PubMed, Embase, and the Cochrane Library up to 30 August 2023. The inclusion criteria comprised English-language original studies on RIRS with or without UAS in humans. The primary outcome was SFR, while the secondary outcomes included intraoperative and postoperative complications, the lengths of the operation and the hospitalization period, and the duration of the fluoroscopy. Subgroup analyses and a sensitivity analysis were performed. Publication bias was assessed using funnel plots and Egger’s regression tests. Dichotomous variables were analyzed using odds ratios (ORs) with 95% confidence intervals (CIs), while mean differences (MDs) were employed for continuous variables. Results: We included 22 studies in our analysis. These spanned 2001 to 2023, involving 12,993 patients and 13,293 procedures. No significant difference in SFR was observed between the UAS and non-UAS groups (OR = 0.90, 95% CI 0.63–1.30, p = 0.59). Intraoperative (OR = 1.13, 95% CI 0.75–1.69, p = 0.5) and postoperative complications (OR = 1.29, 95% CI 0.89–1.87, p = 0.18) did not significantly differ between the groups. UAS usage increased operation times (MD = 8.30, 95% CI 2.51–14.10, p = 0.005) and fluoroscopy times (MD = 5.73, 95% CI 4.55–6.90, p < 0.001). No publication bias was detected for any outcome. Conclusions: In RIRS, UAS usage did not significantly affect SFR, complications, or hospitalization time. However, it increased operation time and fluoroscopy time. Routine UAS usage is not supported, and decisions should be patient-specific. Further studies with larger sample sizes and standardized assessments are needed to refine UAS utilization in RIRS.

50. Enhanced oxygen electrode performance in solid oxide fuel cells via La-doping of Pr2NiO4+δ-based Ruddlesden–Popper perovskites.

Abstract

Solid oxide fuel cell (SOFC) is a high-efficiency, low-carbon power generation device that directly converts the chemical energy of fuel directly into electricity at elevated temperatures. However, the performance of the oxygen electrode, which is critical for the oxygen reduction reaction (ORR), remains limited by high polarization losses and limited long-term stability. Ruddlesden–Popper (R–P) perovskites, such as Ln2NiO4+δ (Ln = La, Pr, Nd), offer excellent oxygen transport due to their unique A–O rock salt layers. In this study, La3+-doped Pr2−xLaxNi0.8Cu0.2O4+δ (x = 0, 0.5, 1.0, PLxNC) oxygen electrode materials are synthesized by the sol–gel method, and their electrochemical properties are systematically investigated. While the electrical conductivity decreases with increasing La3+ content, PL0.5NC exhibits optimal oxygen surface exchange and bulk diffusion properties. SOFC using PL0.5NC as the oxygen electrode achieved excellent performance at 800 °C, with a polarization resistance of 0.245 Ω cm2 and a peak power density of 0.864 W cm−2, a 64% improvement over PNC. This study highlights the potential of La3+ doping to enhance PNO-based oxygen electrodes and provides insight into the development of high performance SOFC materials. [ABSTRACT FROM AUTHOR]
