Melania to leave hospital 'in a few days', says Trump
US President Donald Trump has said his wife Melania will leave hospital in a few days, after receiving medical treatment for a kidney condition the White House said is non-cancerous.
"Our great First Lady is doing really well. Will be leaving hospital in two or three days. Thank you for so much love and support!" Mr Trump tweeted.
The first lady (48) underwent an "embolisation" procedure at Walter Reed National Military Medical Centre outside Washington on Monday morning, her office announced.
The president visited her on Monday evening and tweeted that the procedure was "successful" and that his wife was in "good spirits".
Ms Trump's spokeswoman had said on Monday that the first lady was likely to remain in hospital for "the duration of the week".
The White House has not offered any additional information about her condition, citing her privacy.
Vice President Mike Pence, however, described the procedure as "long-planned" as he opened a speech in Washington on Monday night.
She was last seen in public last Wednesday at a White House event, where she and the president honoured military mothers and spouses for Mother's Day in the US.
She later accompanied the president to Joint Base Andrews in Maryland to welcome home three Americans who had been detained in North Korea.
Two urologists who have no personal knowledge of Ms Trump's condition said that the most likely explanation for the embolisation procedure is a kind of non-cancerous kidney tumour called an angiomyolipoma.
They are not common but tend to occur in middle-aged women and can cause problematic bleeding if they become large enough, said Dr Keith Kowalczyk of MedStar Georgetown University Hospital.
