Abstract:
Objective To summarize the ultrasonic characteristics of urinary calculus in infants who had history of feeding melamine contaminated milk powder.Methods A total of 163 children[aged(19.4?10.9)months] with urolithiasis,who had feeding melamine contaminated milk powder,were retrospectively analyzed using ultrasonography.Twenty children [aged(16.7?9.9)months] with urolit-hiasis,who had no feeding history of melamine contaminated milk powder,were chosen as controls.Ultrasonic characteristics were compared between the 2 groups.Results For melamine calculus cases,sporadic spot or hyperechic mass with different size and shape in the collecting system,partly without acoustic shadow,was found in 65 cases;dense echo and luminous belt with obscured acoustic shadow under a band without echo was found in 48 ureteral calculus cases;irregular strong echo mass or small spot with thick acoustic shadows without side lobe artifact in the dark liquid areas was found in 8 cases with bladder calculus.There was significant difference in morphology of the calculus(P0.05).Conclusions The unique ultrasonic characteristics in infants with melamine calculus had become a very useful tool to diagnose the pediatric urinary melamine calculus.J Appl Clin Pediatr,2009,24(1):67-69
