Use and efficacy of radioiodine therapy in the treatment of hyperthyroidism

Radioiodine (131J) therapy is a method of radical treatment for hyperthyroidism. In our study in the period 1971-1993, we administered radioiodine therapy in 163 patients with hyperthyroidism. We performed a long-term follow-up, from one month, to 21 years after the radioiodine therapy. The cured rate was 83.4%: euthyroid state was found in 43.6% of patients and hypothyroidism appeared in 39.9% of patients. After the radioiodine therapy hyperthyroidism was found in 16.6% of cases. Radioiodine therapy is very efficient, non-invasive, radical treatment of hyperthyroidism, not expensive and easy to administer. It has practically no immediate or long-term complications, except hypothyroidism.
