Giant Bladder due to Chronic Urinary Retension: A Rarely Case Seen in the Emergency Department a Case Report

The giant bladder (GB) is a very rare condition in the elderly population in which the bladder volume increases progressively, usually painlessly. It often develops due to chronic urinary obstruction caused by benign prostatic hyperplasia or neurogenic disorders. Here, we present a case of a GB with a volume of 5,500 mL developed due to chronic urinary retention in a 63-year-old male patient. Only 5 GB cases with a volume of 5 L or more have been reported in the literature. It can lead to a condition that disrupts the quality of life of the patient, such as kidney failure. Rarely, it can cause life-threatening conditions (such as pulmonary embolism) by compressing the large vessels in the abdomen. The GB should be considered in the differential diagnosis of patients admitted to the emergency department with complaints of voiding symptoms and progressive abdominal distension.
