Melania Trump is "doing really well" following a kidney procedure, President Trump said Tuesday.
He gave the update during an annual ceremony honoring fallen police officers.
"Melania is in the hospital doing really well," he said from the steps of the U.S. Capitol. "And I want to thank the incredible doctors [at] Walter Reed Medical Center. They did a fantastic job, so thank you, and she sends her love."
The first lady underwent an embolization, according to her office. The procedure is carried out to cut off blood supply to a growth.
So how would you know if you were affected by a similar condition?
"You might not have symptoms," Dr. Joseph Vassalotti, of the National Kidney Foundation, told Inside Edition. "This might have been detected through imaging, like a CAT scan or an ultrasound."
Symptoms could include blood in the urine and pain in the abdominal area or side, he said.
CNN reporter Kate Bennett told Inside Edition that it's incredible how Melania's staff of about 10 people managed to keep her surgery under wraps.
"I think it's somewhat remarkable that they were able to pull off a surgery with the first lady of the United States being hospitalized and no one found out about it until she was out of the procedure," she said.
Melania is expected to remain at Walter Reed for the remainder of the week. Bennett said it's likely just a precaution.
"This was a significant medical procedure and therefore they just want to keep an eye on her," she said.
