Unusual case of Munchausen's syndrome: factitious vesical lithiasis.

We report an uncommon case of a 38-year-old woman who admitted for bladder lithiasis undergoing repeated surgical management and being apparently recurrent. The intravenous pyelography and retrograde urethrocystography clear the urinary tract. Biologic evaluation eliminates any metabolic or endocrine cause. The confirmation of a factitious origin is given by fluorescence X analysis of the extracted stones which conclude to calcium carbonate structure and psychiatric care. The self-intromission of these calculi into the bladder is due to the personality disorder being in the frame of Munchausen's syndrome. Two years later, no recurrence is noted and an excellent psychiatric care is achieved.
