Unusual case of a gigantic bladder mimicking a large pelvic cystic mass

Pelvic masses are more common in females compared to the males. Bladder distension secondary to urinary retention can also mimic as a pelvic mass. However, it is rare to see chronic urinary retention with no clinical urinary symptoms. We present a case report of an elderly male who presented with abdominal pain and progressive worsening of breathing, along with abdominal distension. Initially, patient was thought to have a large cystic pelvic mass, causing bilateral renal hydronephrosis due to the ureteric compression. However, urinary cauterization drained 19,000 ml of the urine leading to not only resolution of the symptoms but also clinical improvement of the patient.
