Abstract

Objective: To summarize the clinical features and follow-up, the effects of melamine-tainted milk powder (MMP) consumption on kidney and body growth in children who suffered from melamine-related urinary stones (MUS) 2 years earlier were checked. Measurements: Body height and weight, kidney and bladder morphology monitored by ultrasound, urinalysis and renal function were recorded. Plain abdominal radiography was performed for differential diagnosis. The first follow-up was carried out at 15 months and the second 2 years later for patients who showed any abnormality at the first follow-up. Two hundred age- and gender-matched cohorts were included. Results: All cases received conservative treatment in hospital. Fifteen months of follow-up was successfully carried out in 167 cases. 91 children had residual MUS at the time of discharge, 58 MUS disappeared completely, 25 dissolved partially, 1 increased in size, and 7 did not change. At 2 years of follow-up, the residual stones all disappeared except for 1 case; the patient who showed a delayed development with regard to height caught up at 24 months of follow-up. Conclusions: Conservative treatment shows a high effectiveness in cases with residual MUS. Consumption of MMP with timely treatment did not demonstrate an evident impact on kidney and bladder although body height is slightly affected in a few cases.
