Home Oxygen Therapy-Induced Bladder Rupture

An 84-year-old man taking home oxygen therapy (HOT) for chronic obstructive pulmonary disease (COPD) was brought to our emergency department because of cardiopulmonary arrest after connecting an oxygen cylinder to a urinary catheter at home. On physical examination, subcutaneous emphysema and abdominal distension were noted. The oxygen stored in the abdominal cavity seemed to induce abdominal compartment syndrome, so we decided to drain the oxygen. Advanced cardiac life support protocol and drainage were performed, followed by the return of spontaneous circulation. The number of patients on HOT for COPD is expected to increase because COPD is a common disease globally. This patient had a urinary catheter due to urinary retention caused by benign prostatic hyperplasia (BPH). BPH is a benign tumor of the prostate gland that is the most common cause of dysuria in older men. COPD and BPH are very common diseases, so similar medical accidents may occur. We report this case to prevent a recurrence.
