Ongoing research

Hyperthyroidism and radioactive iodine

A follow-up study in our hyperthyroid cats is currently ongoing at the Clinic Small Animals, Faculty of Veterinary Medicine (UGent). This doctoral project is conducted by Lisa Stammeleer under supervision of Prof. dr. Sylvie Daminet.

Why follow up?

There are two main reasons to closely monitor your cat after radioiodine treatment. On the one hand we want to check the success of the treatment, on the other hand it is important to closely monitor the health of your (older) cat.

What can we do for you and your beloved cat?

The Faculty of Veterinary Medicine (UGent) is currently one of the few centers in the Benelux that offers radioactive iodine treatment for hyperthyroid cats. We have a lot of experience with this treatment and are continuously contributing to science to provide the best care for your cat.

With this research we wish to follow up cats that are presented for treatment with radioactive iodine in the long term. This is to find out how thyroid function evolves after treatment and what influence this has on kidney function. The latter is very important as 30-40% of older cats (even without thyroid problems) are affected by kidney problems. Good control of both (kidney function is inextricably linked to thyroid function) can significantly improve your cat's life expectancy .

What does the follow-up entail?

The thyroid and kidney function is monitored through urine and blood examinations. Medical imaging also plays an important role to monitor the thyroid gland, especially scintigraphy. The latter shows the thyroid and its function.
This monitoring should take place before and after radioactive iodine treatment at specified times. We want to closely monitor the treated patients in order to optimize their life expectancy and quality, and to tailor the radioactive iodine therapy as closely as possible to the individual patient.
In short, we want to provide your beloved cat with the best care .

Benefits when participating

Participation in this follow-up study will benefit you and your beloved cat.

  • Your cat will be closely monitored before, during and after the treatment.

  • The ideal follow-up is offered to you free of charge. This includes the follow-up consultations including blood and urine tests, as well as a repeat of the scintigraphic scan at two different timepoints after the radioactive iodine treatment. Blood and urine tests are performed at the time of treatment and 3, 6 and 12 months after treatment.


In short, your cat enjoys the most ideal follow-up and at the same time contributes to science. While you enjoy a significant discount in the follow-up of your cat after treatment with radioactive iodine.
