Now Offering Virtual Visits

Life seems very different during these challenging times, but Washington University Department of Pediatrics is here to care for your child’s needs, just as we’ve always been.

The health of our patients and staff is our top priority. During the COVID-19 pandemic, here is what we are doing to keep everyone safe during your office visit:

  • We require all patients and visitors over 2 years old to wear a mask.
  • Each patient may have two visitors accompany them.
  • You will be screened for symptoms of COVID-19 when you arrive for your appointment. You may be asked to reschedule if symptoms are present.
  • Practice social distancing and stay at least 6 feet apart from others when possible.
  • If you have a MyChart account, please complete the online check-in and payment before your visit.

The Division of Pediatric Nephrology, Hypertension & Pheresis of the Department of Pediatrics at Washington University School of Medicine has outstanding capabilities in cutting-edge research, trainee education and all levels of clinical patient care. Links on this page provide additional descriptions of each of these missions. As of August 1, 2020, the division comprises ten faculty members, two nurse practitioners and two nurse coordinators.

The division provides comprehensive treatment for children who suffer from kidney or genito-urologic disorders, both acute and chronic. This includes evaluation, specialized testing, education and ongoing care, such as the provision of dialysis and kidney transplantation as treatment for chronic kidney disease.

The pediatric nephrology division works closely with outstanding programs in Adult Nephrology, Pediatric Urology, Pediatric Rheumatology, and Transplant Surgery.
