Intravesical migration of female urethral dilator: a case report of a new urologic emergency in the era of e-commerce.

BACKGROUND: The introduction of foreign bodies in the female urethra for auto-erotic stimulation or in case of psychiatric disorders is not uncommon. The occurrence of intravesical migration of these objects makes it necessary to remove it shortly after insertion, since after long term permanence complications are likely to occurr.

CASE PRESENTATION: A 47-year-old white female was referred at our Urology department for migration inside the bladder of a metallic urethral dilator used for sexual stimulation. An ultrasound study and an X-ray plate of the pelvis clearly visualized the presence of an object shaped like a rifle bullet located in the bladder. Twenty-four hours later, the patient reported its spontaneous emission through the urethra during micturition. This was confirmed by US and X-ray imaging.

CONCLUSIONS: The retrieval of foreign objects introduced through body orifices with purpose of sexual gratification is a known urological expertise. Curiously, in the case reported, the patient was able to manipulate the object thus facilitating its correct orientation and passage outside the bladder during micturition. To the best of our knowledge this is the first case of documented spontaneous emission through the urethra of a sizable intravesical foreign body. Sexual gratification in females though the insertion of urethral dilators is a growing practice, as demonstrated by the broad proposal of such instruments on the web. Therefore, the occurrence of accidental intravesical displacement of such kind of foreign body is increasingly likely, and the Urologists must be aware of this possibility.
