Bladder foreign bodies have been reported with a great variety, including daily objects and even living things. Except for these, thermometer in bladder were reported with several cases. Due to the limitations of surgical equipment, the removal of bladder thermometer was initially performed with manipulation combined with forceps for female patients, and now it has been taken out with the assistance of various endoscopes. In this report, a 25 years old male inserted a thermometer in his bladder, and a transurethral cystoscopic removal procedure was conducted with a stone extractor.
