    BACKGROUND: Liver, spleen and kidney dimensions on ultrasonography vary with the age, weight and ethnicity. Reference standards of these parameters for normal Sri Lankan children are not available. Our aim was to establish normative data for longitudinal length of liver, spleen and kidneys in healthy children. METHOD: Three hundred fifty-seven children, 5-13 years of age were selected from two randomly selected schools in the Gampaha district in the western province of Sri Lanka. A questionnaire was administered to the parents after obtaining informed written consent. Participants were screened for risk factors for organomegaly and were examined by a trained officer. Children with a past history of infective, inflammatory, haematological, malignant, congestive, collagenous or congenital conditions that can affect the size of the organs were excluded as well as those with clinically evident malnutrition, anemia, lymphadenopathy or organomegaly. Ultrasonographic assessment was done using a high resolution real-time scanner with a 3.5 MHz convex transducer by a trained officer. Children with ultrasonographic abnormalities of organs were also excluded from the study and referred for further evaluation. RESULTS: The study comprised 332 children comprising 176 girls (53%). There was a significant difference in the longitudinal dimension of the liver between the two sexes with a higher value recorded among females (Mann Whitney U = 11,830.5, p = 0.037). Body weight was correlated with the dimensions of the liver, the spleen and the kidneys. On multiple regression analysis body weight significantly associated with all the organs. (p < 0.01) Percentile graphs for longitudinal length of liver, spleen, right and left kidneys were formed according to the body weight. CONCLUSION: The organ dimensions showed the highest correlation with body weight. We hope the normal ultrasonographic values of healthy Sri Lankan children will assist in interpretation of sonographic examinations in daily clinical practice.

    Ultrasonographic parameters of the liver, spleen and kidneys among a cohort of school children in the Gampaha district
    (Sri lanka Medical Association, 2015) Warnakulasuriya, D.T.D.; Peries, P.P.U.C.; Rathnasekara, Y.A.C.; Jayawardena, K.A.T.M.; Upasena, A.P.
    INTRODUCTION AND OBJECTIVES: Liver, spleen and kidney dimensions on uitrasonography vary with age, weight and ethnicity. Reference standards for these parameters in normal Sri Lankan children are not available. Our objective was to establish normative data for the longitudinal length of the liver, spleen and kidneys in healthy children living in the Gampaha District. METHOD: A total of 357 children between the ages of 5 to 12 years were selected from two randomly selected schools in the Gampaha District. A questionnaire was administered to the parents after obtaining informed written consent. Participants were screened for risk factors for organomegaly and were examined by a medical officer. Ultrasonographic assessment was done using a high resolution real-time scanner with a 3.5MHz convex transducer by a trained medical officer. Children with abnormalities in the Ultrasonographic appearance of organs were excluded. RESULTS: The study comprised 332 children (176 girls, 53%). There was no difference in organ dimensions between the two genders (p > 0.05). Body weight showed the best correlation with liver, spleen and kidney dimensions. Age significantly correlated with the longitudinal length of the liver and height significantly correlated with spleen length. Percentile graphs for the longitudinal length of the liver, spleen, right and left kidneys were developed in relation to body weight.
