Objective Diabetes mellitus is a common public health problem due to the seriousness of its complications. It can be harmful for the kidneys of these patients and it is useful to take preventive therapeutic measures against the various lithiasis.

Methods The survey includes 116 diabetics (type I), where first morning urine samples were examined with an optical microscope with polarization for qualitative and quantitative analysis of crystalluria.

Results Calcium oxalates were mainly in abundance in the both sexes compared to other crystalline species, with a frequency of 79.5% at direct examination and 84.6% at +4°C. The total frequency of purins was 22.0% in the direct examination. The crystalluria observed in the type I diabetic showed a prevalence of oxalo-calcic type (Weddelitte) crystals with a frequency of 64.5%, followed by Whewellite (15.0%).

Conclusion The high percentage of purin crystalluria for diabetic subjects in general gives an index of danger to the clinicians and the experts.
