Foreign body stone of the ureter as a complication of acupuncture.

Aso Y, Murahashi I, Yokoyama M.

A case of spontaneous passage of a foreign body in the upper urinary tract is reported. Approximately 60 cases have been collected and reported in the world, 18 in Japan. Our case is, however, the first with spontaneous passage. As complications may occur if these foreign bodies are left behind, we advocate the surgical removal as treatment of choice.
