Two calculi were discovered in an 84-year-old woman who was a bedridden resident of a nursing home. One calculus was just external to the vagina, and the other was inside. Both were foul smelling, 1 to 3 cm in diameter, tan in color, porous, and crispy (Fig. 1). A chemical analysis revealed the calculi to be composed of magnesium and ammonium phosphate. The patient did not have a urethrovaginal fistula.
