    Radiologist agreement on diagnosing urolithiasis (kidney stones) varied. While generally good for detecting patients with stones, variations occurred in stone count and size. Tomography imaging improved consistency.

    Area of Science:

    • Radiology
    • Urology
    • Medical Imaging

    Background:

    • Diagnosing urolithiasis (kidney stones) relies on radiologic interpretation.
    • Interobserver variability among radiologists can impact diagnostic accuracy and patient management.
    • Understanding factors influencing this variability is crucial for improving diagnostic reliability.

    Purpose of the Study:

    • To assess interobserver variations in diagnosing urolithiasis among radiologists with diverse backgrounds.
    • To evaluate the impact of imaging techniques, specifically tomography, on diagnostic agreement.
    • To identify factors influencing radiologist agreement in urolithiasis evaluation.

    Main Methods:

    • Analysis of conventional abdominal films and urography/tomography from 152 consecutive patients.

  • Independent interpretation by three radiologists with varying experience and departmental affiliations.
  • Assessment of agreement on patient presence/absence of calculi, stone count, size, and location, and associated findings like hydronephrosis.

    • Main Results:

    • High agreement (129/152 cases) was observed in identifying patients with or without calculi.
    • Significant variability noted in total stone counts (832, 460, 570) and median stone size (6, 9, 11 mm²).
    • Tomography significantly reduced interobserver variability compared to conventional methods; bowel preparation and projections had no impact.

    Conclusions:

    • Interobserver variations in interpreting urolithiasis imaging are significant, particularly for stone burden and characteristics.
    • Tomography is a valuable tool for reducing variability in radiologic evaluation of kidney stones.
    • Variability in radiologic interpretation is a critical factor affecting the reliability of urolithiasis diagnosis.
