Introduction: The aim of this study was to present the surgical technique and clinical outcomes of modified ileal conduit for pelvic lipomatosis (PL). Methods: From 2020 to 2022, we prospectively enrolled 9 patients with PL undergoing modified ileal conduit. The patient characteristics, perioperative variables, and follow-up outcomes as well as the description of surgical technique were reported. Results: All 9 patients successfully completed the operation. Two patients had perioperative complications of Clavien-Dindo grade I. The mean operation time and bleeding volumes were 253 ± 51.4 min and 238.9 ± 196.9 mL, with a mean postoperative follow-up time of 13.0 ± 5.6 months. The postoperative 3-month and 1-year creatinine values were significantly decreased versus the preoperative (p = 0.006 and p = 0.024). The postoperative 3-month and 1-year estimated glomerular filtration rate values were significantly increased compared with those before operation (p = 0.0002 and p = 0.018). The separation value of left renal pelvis collection system after operation was significantly reduced compared with preoperative evaluation (p = 0.023 at 3 months and p = 0.042 at 1 year) and so was the right side (p = 0.019 and p = 0.023). Conclusion: Modified ileal conduit is safe and feasible for PL. A large sample cohort with long-term follow-up is needed to evaluate the clinical outcomes of PL.

Electrides have been extensively investigated, which revealed many exotic properties. Here, we suggest two feasible two-dimensional (2D) ferromagnetic electrides HfBa 4 X 8 (X = Cl, Br), whose ground state displays a quantum anomalous Hall effect (QAHE) state with an easy x-axis magnetization. Excess electrons in these materials are confined in the cavity channel created by Ba 2+ cations and X − anions and considerably affect both the magnetic and topological properties. By rotating the magnetization counterclockwise starting from the x axis, the system can achieve two QAHE states with the opposite Chern number and a period change of the band gap, and a 2D Weyl half-semimetal state will act as a critical point with the magnetization along the y axis. Our findings provide a material family platform for studying magnetic topological phase transition in electrides, which may exhibit unique applications in spintronic devices.

Ferromagnetic (FM) states with high Curie temperatures (T c ) and strong spin−orbit coupling (SOC) are indispensable for the long-sought room-temperature quantum anomalous Hall (QAH) effects. Here, we propose a two-dimensional (2D) iron-based monolayer MgFeP that exhibits a notably high FM T c (about 1525 K) along with exceptional structural stabilities. The unique multiorbital nature in MgFeP, where localized d x y 2 2 and d xz/yz orbitals coexist with itinerant d xy and d z 2 orbitals, renders the monolayer a Hund's metal and in an orbital-selective Mott phase (OSMP). This OSMP triggers an FM double exchange mechanism, rationalizing the high T c in the Hund's metal. This material transitions to a QAH insulator upon consideration of the SOC effect. By leveraging orbital selectivity, the QAH band gap can be enlarged by more than two times (to 137 meV). Our findings showcase Hund's metals as a promising material platform for realizing high-performance quantum topological electronic devices.
