Melania Trump returns to White House after successful kidney surgery

US First Lady Melania Trump returned to the White House today after undergoing a procedure to address a "benign" kidney condition.

"She is resting comfortably and remains in high spirits," the White House said in a statement.

The Slovenia-born former model underwent an embolization procedure, according to her communications director Stephanie Grisham.

Embolization is most frequently used to cut off the flow of blood to a tumor or growth.

It is common to stay overnight after the procedure to treat the pain.

Earlier, Melania Trump said she felt "great" after a kidney procedure and expects to return to the White House before long. Her husband is visiting her in the hospital for the third straight day.

The first lady's comments on Twitter on Thursday were her first since she was hospitalised for an embolization on Monday. She tweeted "a sincere thank you to Walter Reed Medical Unit" and to her well-wishers.

Melania added, "I am feeling great & look forward to getting back home."

President Donald Trump is visiting his 48-year-old wife for the third day in a row. The 72-year-old president joked during a visit to the Capitol today that the first lady should be the one visiting him in the hospital, not the other way around.

Melania Trump, underwent a surgical procedure to treat a benign kidney condition and remained at Walter Reed medical centre for the a week.
