SIOUX FALLS, S.D. — An Iowa woman is suing a South Dakota surgeon and his practice for wrongly removing one of her kidneys.

The lawsuit filed by Dena Knapp alleges that Dr. Scott Baker erroneously removed her healthy right kidney instead of removing an adrenal gland and a mass on the gland during a surgery in Sioux Falls in 2016.

The Argus Leader reports the lawsuit alleges the erroneous surgery resulted in an incurable and progressive kidney disease in Knapp’s remaining kidney that has caused pain and mental distress.

Knapp eventually had a second surgery at the Mayo Clinic in Rochester, Minnesota, to remove the gland and mass.
