The rotation method for correcting renal depth in the determination of glomerular filtration rate using Tc-99m diethylenetriamine pentaacetic acid (DTPA)-based renal dynamic imaging in patients with hydronephrosis.
Quant Imaging Med Surg

Department of Nuclear Medicine, First Hospital of Shanxi Medical University, Taiyuan, China.
Background: Kidney depth significantly affects the accuracy of glomerular filtration rate (GFR) measurement, and hydronephrosis-induced morphological changes further challenge its estimation through traditional formulas. This study evaluated the rotation method's efficacy in correcting kidney depth and depth difference during Tc-99m diethylenetriamine pentaacetic acid (DTPA) renal dynamic imaging for GFR assessment.
Methods: This study analyzed 66 individuals treated at First Hospital of Shanxi Medical University with unilateral hydronephrosis between January 2022 and June 2023.
Caloric restriction exacerbates renal post-ischemic injury and fibrosis by modulating mTORC1 signaling and autophagy.

Objective: This study investigates the effects of caloric restriction (CR) on renal injury and fibrosis following ischemia-reperfusion injury (IRI), with a focus on the roles of the mechanistic/mammalian target of rapamycin complex 1 (mTORC1) signaling and autophagy.
Methods: A mouse model of unilateral IRI with or without CR was used. Renal function was assessed through serum creatinine and blood urea nitrogen levels, while histological analysis and molecular assays evaluated tubular injury, fibrosis, mTORC1 signaling, and autophagy activation.
Comparison of radiation exposure for interventional radiology vs urology-guided renal access for percutaneous nephrolithotomy.

Department of Urology, MedStar Georgetown, Georgetown University School of Medicine, 3900 Reservoir Rd NW, Washington, DC, 20007, USA.
Introduction: Radiation exposure during percutaneous nephrolithotomy (PCNL) can vary depending on the method used for renal access. This study aimed to compare fluoroscopy time and dose during PCNL when renal access is achieved via interventional radiology (IR) versus urology.
Methods: A retrospective review of patients who underwent unilateral PCNL between January 2020 and February 2023 was conducted.
Supranormal renal function in pediatric ureteropelvic junction obstruction: a multiparameter analysis to guide clinical management.

Pediatric Urology and Regenerative Medicine Research Center, Children's Medical Center, Tehran University of Medical Sciences, No. 62, Dr. Gharib's Street, Keshavarz Boulevard, Tehran, 1419433151, Iran.
Background: The clinical significance and optimal management of supranormal differential renal function (DRF ≥ 55%) in pediatric ureteropelvic junction obstruction (UPJO) remain debated. This study investigated supranormal DRF clinical characteristics and evaluated surgical versus conservative management outcomes to guide decision-making.
Methods: We retrospectively reviewed 76 children with unilateral UPJO who underwent standardized DMSA and DTPA scans at a single center (2020-2022).
