Doctors in China solved the years-old mystery of why one 26-year-old patient was experiencing abdominal pain when they found her IUD in her bladder.
The patient got the IUD inserted in 2011, but got pregnant months later and gave birth February 2012.
But when her child was born via a c-section doctors found no trace of the IUD and assumed it had become embedded into her uterus.
However, an x-ray of the woman’s pelvis finally explained why she had become pregnant despite having taken the preventative measure: the IUD had perforated her uterus and traveled to her bladder, which was causing urinary tract complications.
