Index test:1.Prediction of urinary calculi mineral composition using intraoperative endoscopic videos
2.Prediction of urinary calculi mineral composition using stone specimen photographs
3.Prediction of urinary calculi mineral composition using preoperative CT scans.

Inclusion criteria
Inclusion criteria: 1.Possession of a valid Medical Practitioner’s License, and >=1 year of clinical work experience in the Department of Urology at a secondary or higher-level hospital; 2.Proven routine experience in the diagnosis and treatment of urinary calculi, with participation in >=50 urinary stone surgeries within the past year, and familiarity with intraoperative endoscopic procedures and imaging features of urinary stones; 3.Commitment to full participation in the blinded assessment process, ensuring timely completion of composition identification and scoring for all samples, and agreeing not to access infrared spectroscopy results or any other external reference materials during the assessment period.
Exclusion criteria
Exclusion criteria: 1.Those engaged only in basic urological research with no hands-on clinical experience; 2.Those who have not participated in urinary stone-related surgeries within the past year, or have insufficient experience in interpreting stone endoscopic images and CT scans; 3.Those with visual impairments (e.g., color blindness, uncorrected severe myopia, etc.) that may affect the accuracy of image recognition; 4.Those who are unable to complete all assessment tasks due to work transfers, leave, or other reasons, or who refuse to cooperate with the research procedures.
