Résumé:
Objective:
To detect a correlation between crystalluria and symptomatic hematuria, which
may be indicative of urological or kidney disease.
Methods:
A total of 617 first morning urine from 306 patients, including 59 urolithiasic
subjects and 247 patients with other urinary tract problems but without lithiasis, were collected
and analyzed by a light microscope and urine dipsticks. Meanwhile, 202 urines from 100
healthy subjects were analyzed to compare results.
Results:
Results show that in patients with hematuria, 81.08% of urolithiasis, 32.39% of
patients without urolithiasis and 21.88% of controls had a positive crystalluria. The crystalline
species most encountered in urolithiasis was whewellite with 37.84% followed by uric acid
dihydrate with 21.62%.
Conclusions:
In most cases, the formation and growth of a calculi are the result of urinary
disorders, metabolic, infectious or anatomical, whose identification can provide prophylactic
and preventive measures of recurrence kidney stones.
