RESUMO
A sixty-three-year-old Caucasian male was referred to emergency service 10 hours after self-infliction of a mercury glass thermometer into the urethra. The patient presented without abdominal or voiding symptoms. Radiologicalimaging confirmed the presence of a thermometer in the peritoneal cavity, without signs of contrast leakage from the bladder. The patient underwent suture of the perforation site with a subsequent successful removal of the foreign body using laparoscopic approach. Recovery was uneventful.To the best of our knowledge, we are not aware of any previous report of laparoscopic removal of a mercury glass thermometer from the peritoneal cavity. Laparoscopic removal of fragile items, such as a thermometer, is obviously feasible but associated with substantial risks.
