Key Points

  • To investigate the effects of intravenous iodinated contrast media on urinalysis parameters in dogs undergoing CT scans.
  • Conducted urinalysis before and after administration of contrast media.
  • Monitored changes in urine specific gravity and pH.
  • Analyzed data to assess the significance of any changes.
  • Urine specific gravity transiently increased after contrast administration.
  • Urine pH also showed a temporary rise.
  • No significant effects were observed on other urinalysis parameters.

Abstract

These findings provide practical guidance for accurate interpretation of urinalysis in dogs undergoing CT with contrast media. If USG or pH are critical for patient management, urinalysis should be performed before or on a different day than contrast administration.
