Modern literature has many similar instances.
In the older literature it was not uncommon to find accounts of persons passing worms from the bladder, no explanations being given to account for their presence in this organ.

Some of these cases were doubtless instances of echinococcus, trichinae, or the result of rectovesical fistula, but Riverius mentions an instance in which, after drinking water containing worms, a person passed worms in the urine.

In the old Journal de physique de Rozier is an account of a man of forty-five who enjoyed good health, but who periodically urinated small worms from the bladder.

They were described as being about 1 1/2 lines long, and caused no inconvenience.

There is also mentioned the case of a woman who voided worms from the bladder.
