  Author(s): Jing Li, Ningning Liu*, Xiaoyi Wang and Haijie Xie
  
  Objective: The purpose of this study was to preliminarily predict the chemical composition of urinary calculi using ultrasound in vivo. Methods: A retrospective analysis was performed on the data of 267 patients with urinary calculi, including Non-Contrast Computed Tomography (NCCT) and ultrasound imaging data obtained before intervention, as well as the chemical composition after intervention. Statistical analysis was performed on the Hounsfield Unit (HU) value of the calculi, the grayscale value of the calculi, and the grayscale value of the posterior acoustic shadow of the calculi on ultrasound. Results: The chemical composition analysis indicated that there were four types of mixed calculi; the main components were Calcium Oxalate Monohydrate (COM) calculi, Calcium Oxalate Dihydrate (COD) calculi, Carb..
