Your condition requires you to do a drainage which involves placing a flexible tube, called a "drain" through the skin to empty what is called a collection (accumulation of fluid) or an abscess. The positioning of the drain will be guided under radiological control (ultrasound, scanner or fluoroscopy). In terms of patient irradiation, no risk could be demonstrated in patients, given the low doses used and the precautions taken to limit the area examined to the strict minimum.
