Quantitative evaluation of chronically obstructed kidneys from noncontrast computed tomography based on deep learning

•The U-Net model can measure and report the renal volume parameter of chronically obstructed kidneys with high efficiency.•Renal volume parameters wra associated with split glomerular filtration rate (sGFR) in chronically obstructed kidneys.•Noncontrast computed tomography may be a single radiological procedure for morphological and functional evaluation of chronically obstructed kidneys.
