A Rare Case of an Intermittent Urinary Catheter Discovered Inside a Bladder.

Foreign objects inserted through the urethra, for sexual gratification and ending up in the urinary bladder, are rarely encountered. Patients usually present at emergency departments, reporting abdominal pain, recurrent urinary tract infections (UTIs), or haematuria. Only a few cases present without any symptoms and are incidental findings, commonly during diagnostic work-up for bladder lithiasis or recurrent UTIs. We report a case of an encrusted intermittent catheter, discovered in the bladder of a 72-year-old female patient, with a history of multiple sclerosis (MS) and recurrent UTIs. The foreign body was removed following laser defragmentation of the calculus. No indication of stone recurrence was documented during the six-month follow-up.
