Abstract:
Objective To analyze the CT findings of melamine induced urinary calculi.Methods Nineteen children with a history of ingestion of melamine contaminated infant formula milk were studied, including 12 males and 7 females, age ranged from 50 days to 5 years.Results CT demonstrated renal pelvic and ureteral stones in 13 cases, with urinary obstruction in 9 of them.The size of the stones ranged from 0.3 cm × 0.3 cm to stag-horn calculus.The density of the stones measured from a low of 40-70 HU up to a high of 410 HU with an average density of 160 HU.Conclusion CT scan is an excellent modality in demonstrating urinary tract calculi caused by melamine. It is the method of choice when ultrasound examinations are equivocal.
