Syndi Miske underwent a six-hour surgery in 2011 because she thought it would help her have another baby, but she never got pregnant, according to a complaint she and her husband filed in Nebraska.
Instead, Miske of Wibaux, Mont., immediately began experiencing "significant hot flashes, night sweats and bloating, pain and discomfort in her abdomen," according to a malpractice lawsuit she and her husband filed this month against physicians at Pope Paul VI Institute for the Study of Human Reproduction and Creighton University Medical Center in Omaha, Neb.
When the pain persisted, a radiologist found what appeared to be a large ovarian cyst in 2012, according to the lawsuit. Another doctor told her she should see an oncologist, it said.
After undergoing "repeated intrusive diagnostic procedures, investigations and treatments," Miske had a total hysterectomy Sept. 4, 2013.
That's when they found it, according to the lawsuit.
Instead of a cyst, surgeons discovered a surgical glove in Miske's abdominal cavity. It was tied in a knot, filled with clear fluid and surrounded by Miske's own tissue.
Miske and her husband have sued her doctors in Nebraska for professional negligence, failure to tell her the initial surgery was unlikely to help her get pregnant, and damaging her family relationships.
"Darin Miske personally suffers from injuries to his wife, Syndi Miske, in the form of loss of consortium, namely his wife's affection, companionship, comfort, assistance and conjugal society," according to their lawsuit.
It alleges that the glove was left after the six-hour surgery in 2011. The suit requests "future compensatory damages in an amount to be specified at a later time."
Neither Miske, her lawyers nor the Pope Paul VI Institute and Creighton medical center have responded to ABC News' requests for comment.
