  • Background

    Christopher J. Long, MD, has roots in the Philadelphia area, having grown up in Southern New Jersey. He stayed close to home where he received his bachelor’s degree from the University of Pennsylvania and his medical degree from Rutgers New Jersey Medical School. Dr. Long completed his internship and residency in Urology at Temple University Hospital in Philadelphia, and a Pediatric Urology fellowship in the Division of Urology at The Children’s Hospital of Philadelphia.

    Dr. Long was awarded the prestigious Urologic Care Foundation Research Scholar Award for his work during his fellowship examining the pathophysiology behind the bladder’s response to outlet obstruction. Expanding upon his research interests, Dr. Long will be part of the team caring for children with neurogenic and non-neurogenic bladder dysfunction.

    His additional clinical interests include complex reconstruction, hypospadias, oncology and stone disease, as well as applying both laparoscopic and robotic-assisted minimally invasive techniques to pediatric genitourinary reconstruction.

    Dr. Long’s clinical research interests include the renal trauma experience at The Children’s Hospital of Philadelphia along with establishing a standardized assessment model for hypospadias outcomes and risk assessment. His basic science research includes developing and studying collangenase as a potential medical therapy for bladder hypertrophy.
