As one of the top-ranked kidney care programs in the nation, the Division of Pediatric Nephrology at Children’s Mercy provides family-centered care for children and teens with kidney and urinary tract disorders. Our leadership in innovative research projects—like CKiD, the largest study of children with chronic kidney disease in North America—is actively improving the way we care for kids.


Kidney care that puts your family first


Our expert care team puts their experience to work every day to provide comprehensive care for children and families.

Children’s Mercy doctors have made significant contributions to the study and understanding of kidney disease and related issues in children.

We work closely and collaboratively with other professionals and institutions in the U.S. and around the world to advance the care of children with kidney disorders. Our doctors helped create a set of internationally accepted guidelines for health care professionals who care for children with kidney disorders.

Our dialysis program is nationally and internationally recognized as a leader in pediatric dialysis care and research.


Why choose a top-ranked program


Children with significant kidney disease tend to be extremely complex patients, and centers that are ranked high have excellent patient outcomes. Children’s Mercy has a 100% successful transplant rate and our dialysis program has one of the lowest infection rates in the country. In the video below, Nephrology Division Director Bradley Warady, MD, shares the division’s #4 national ranking of best pediatric kidney programs by U.S. News and World Report, the program’s outstanding transplant outcomes, and leadership in research and quality initiatives that are helping children with kidney disease around the world.

This level of expertise, along with our transition to adulthood program and our focus on family-centered care, make us stand out as a leader in pediatric kidney care.

Clinical Services

The Hypertension Clinic at Children's Mercy provides specialized care for children with high blood pressure, a common complication of chronic kidney disease. Our pediatric nephrologists develop care plans tailored for each child's needs while collaborating with highly trained nurse practitioners to manage ongoing care.

Children with all types of bone disorders are evaluated and treated in the Bone and Mineral Health Clinic. We can also help children with kidney stones and problems with the way their body processes minerals.

The Enuresis and Voiding Disorder Clinic evaluates and treats children who have urinary problems in the daytime or bedwetting at night. We take a collaborative approach to treatment, making sure your child receives the unique and compassionate care they need.

The Dialysis Program at Children's Mercy cares for children with all types of kidney disorders who need renal replacement therapy with dialysis. Our program is nationally and internationally recognized as a leader in pediatric dialysis care and research.

Children's Mercy operates the largest pediatric kidney transplant program in Missouri and Kansas. The transplant program complements the nationally recognized pediatric dialysis program and is a key component of the Division of Nephrology, which ranks as one of the top 5 programs in the country by U. S. News and World Report.

When your child is comfortable and familiar with their Children’s Mercy care team, the thought of leaving the doctors and nurses they’ve known for several years can be overwhelming. To make sure that they’re set up for success, the dialysis and transplant patients we care for go through our transition to adulthood program.
