Abstract: Objective To study the relation between thyroid nodule and urine iodine and to provide a scientific basis for etiological research of thyroid nodule.Methods 178 cases of thyroid nodule were detected urine iodine concentration (μg/L) by As ( Ⅱ ) 2Ce4 + catalytic spectrophotometry.160 normal people were set as control group.Data of the 2 groups and the correlative clinical information were analyzed.Results The median urine iodine concentration was 116.2 μg/L for the 178 cases of thyroid nodule,217.2 μg/L for the control group.Among the 178 cases,the median urine iodine concentration was 125.6 μg/L for the 92 cases with nodule size ＞ 10 mm and 136.4 μg/L for the 86 cases with nodule size ＜ 10 mm.The difference of urine iodine had no statistical significance between the thyroid nodule group and the control group.There was no correlation between urine iodine and the size of thyroid nodule as well as sex.Conclusions No correlation is found between urine iodine and thyroid nodule.Patients with thyroid nodule,no matter male or female,don't have to restrict iodine intake excessively.
