Revisiting Standard Percutaneous Nephrolithotomy in the Mini-Percutaneous Nephrolithotomy/Retrograde Intrarenal Surgery Era: A Retrospective Audit.

Objective This study aims to identify the risk factors associated with postoperative complications following standard percutaneous nephrolithotomy (PCNL) for better results with the emergence of mini-percutaneous nephrolithotomy (mini-PCNL)/retrograde intrarenal surgery (RIRS) in recent years. Methodology This retrospective study was conducted in the Department of Urology, Sri Ramachandra Institute of Higher Education and Research, tertiary health care center in Chennai, India, from January 2018 to December 2023. Records of demographic information, along with clinical presentations like any urinary tract infection (UTI), hematuria, or loin pain were recorded.

Wunderlich Syndrome With a Myriad of Presentations: A Case Series.

Wunderlich syndrome (WS), characterized by spontaneous nontraumatic renal or perinephric hemorrhage, presents a significant diagnostic challenge due to its varied causes and clinical manifestations. Despite its historically high case fatality rate, prompt and accurate diagnosis combined with a multidisciplinary treatment approach has been shown to significantly improve patient outcomes. This case series discusses three patients with diverse presentations of WS, each managed with tailored therapeutic strategies involving a combination of conservative management, super selective renal artery embolization, and surgical interventions such as nephrectomy.

Zinc oxide nanoflakes supported copper oxide nanosheets as a bifunctional electrocatalyst for OER and HER in an alkaline medium.

Bifunctional electrocatalysts are the attractive research in the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in the overall water-splitting reactions. The design and development of the cost-effective OER/HER bifunctional electrocatalysts with superior catalytic activity are still remaining as the big challenges. Herein, we have developed the CuO-ZnO nanocomposite as a bifunctional OER/HER electrocatalyst via simple chemical precipitation method.

4-Carboxyphenyl as efficient donor group in nano Zn-Porphyrin for dye sensitized solar cells.

Dye-sensitized solar cells, represent the alternate technology in solar research due to their cost effective, easy fabrication processes, higher efficiencies, and design flexibility. In this research, dual donor group modified zinc porphyrin dyes, have been synthesized for DSSCs. The complexes of zinc porphyrin functioned as acceptor or attaching groups within each mesophenyl ring and carboxylic acid.
