Melania Trump undergoes procedure 'to treat a benign kidney condition'

First lady Melania Trump underwent a medical procedure to "treat a benign kidney condition" on Monday morning (local time) at Walter Reed National Military Medical Center and is expected to remain hospitalised for the rest of the week, according to her communications director.

"The procedure was successful and there were no complications," according to a statement released by the White House. "Mrs. Trump is at Walter Reed National Military Medical Center and will likely remain there for the duration of the week. The First Lady looks forward to a full recovery so she can continue her work on behalf of children everywhere."

The statement vaguely described the procedure as "an embolisation procedure to treat a benign kidney condition" but offered no additional details about the first lady's condition or treatment.
