Lateral decubitus: its influence on hemodynamic and respiratory function during retroperitoneal robotic assisted laparoscopic pyeloplasty (R-RALP) in children.

Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) is the commonest urologic procedure performed in children, entailing retroperitoneal CO2 insufflation and lateral decubitus, whose effects on cardiopulmonary variables are poorly known. We, therefore, studied hemodynamic and respiratory changes due to CO2 insufflation and lateral decubitus in children undergoing R-RALP and their effects on regional tissue oxygenation. Between 1/2021 and 7/2024, children affected by ureteropelvic joint obstruction (UPJO) underwent a pyeloplasty by R-RALP at Necker Enfants Malades Hospital (Paris, France), using a standardized surgical technique and a lung-protecting anesthetic protocol aimed to prevent hypercarbia.

Ureters can be visualized on a monitor via fluorescence observation technology and an near-infrared (NIR) fluorescent ureteral catheter (NIRFUC). Eureka, an artificial intelligence (AI) platform, can be used to analyze surgical videos and highlight nerves and loose connective tissue (LCT) in the dissection layer. In this study, we aimed to evaluate the feasibility of using simultaneous NIRFUC and AI assistance for anatomical recognition during laparoscopic surgery.

A high incidence of ureteral diseases was needed to find better treatments such as implanting ureteral stents. The existing ureteral stents produced a series of complications such as bacterial infection and biofilm after implantation. The fused deposition modeling (FDM) of 3D printing biodegradable antibacterial ureteral stents had gradually become the trend of clinical treatment.

Objective: To assess the capability of determining the mixed chemical composition of urinary stones using spectral imaging properties of Dual Energy Computed Tomography (DECT) Gemstone Spectral Imaging (GSI) software.
Material And Methods: Twenty-six single and 24 mixed composition ex vivo urinary stones with known chemical composition determined by Fourier-transform infrared spectroscopy (FTIR) prior to this project were scanned with DECT imaging and GSI in vitro. The major components of the stones included Uric Acid (UA), Calcium Oxalate (CaOx), Calcium Phosphate (CaP), Magnesium Ammonium Phosphate (MAP), and Cystine (Cys).
