CHARLOTTE, N.C. — Patients at Levine's Children's Hospital got the chance to pie their nurses and doctors on National Pi and World Kidney Day. 

The event was to raise awareness for kidney disease, a serious disease that affects hundreds of local patients. 

Several past and present Levine's patients took aim and threw whipped cream pies at their doctors and nurses to help raise funds for Levine Children’s Pediatric Nephrology Center of Excellence. 

Dr. Susan Massengill, Director of Nephrology and Hypertension at Levine Children's Hospital, said Thursday's event is a great way to raise awareness for a disease that doesn't get the same amount of attention as heart or liver disease. 

"You could look at these kids today," Dr. Massengill said." And as sick as they may be, you'd have no idea." 

As well as raising awareness, Dr. Massengill also said today is all about "fun for the patients." 

"Because it's World Kidney Day as well as Pi Day, we're allowing some of our patients and some of the staff to pie those of us in my division," Dr. Massengill said. 

Massengill said one of the main issues surrounding Chronic Kidney Disease is that most people don't know they have it.  

"It affects 1 in 10 people worldwide," Dr. Massengill said. "There is no cure for it. You may be transplanted but you'll need another transplant at some time."  

Dr. Massengill hopes to educate those who might not know much about the disease. If you want to donate a kidney, Dr. Massengill said all you need to know is your blood type. 

According to Dr. Massengill there are over 1000,000 people waiting for kidneys and about 500 children who are waiting for kidneys in the nation.

"It's the greatest that anyone could ever could give," Dr. Massengill said. 

Narciso Ocampo, a father of two boys who both received kidney transplants at Levine Children's Hospital, said he is forever grateful for the doctors who saved his sons' lives. 

"They have become our second family," Ocampo said. 

He also said by allowing patients to throw pies at the doctors, it shows another side of them that many may not see. 

"It shows you the heart and soul of the doctors, [they're] willing to submit to embarrassment and just the attitude they have for keeping this on the front page as far as kidney awareness," Ocampo said.  

Levine Children’s pediatric nephrology program is ranked 20th in the nation by U.S. News & World Report and in just 3 years, $2.5M has been raised to fund research and improve care outcomes for the center of excellence.
