About Christopher J. Long, MD
In the Division of Urology, Christopher Long, MD, takes a personalized approach to patient care. He believes treatment starts with an understanding of each patient’s needs and goals.
“I try to spend time in the visit getting to know the family and making this more than a doctor's visit for a specific diagnosis,” he explains. “Since we are specialists, patients typically present with a very focused and specific problem. As part of the visit, I want each patient, regardless of the number of times I have to see them or what I have to do for them, to feel as though we've impacted their life in a positive and meaningful way.”
Dr. Long became interested in pediatric urology during his residency training, which was focused primarily on treating adult patients.
“Having the ability to treat and help patients across a very diverse set of medical problems, from infancy through adulthood, was very appealing to me,” he explains. “I really enjoy the challenge of such a diverse patient population and find it rewarding to help so many people live better lives. The impact of our intervention lasts a lifetime!”
One of Dr. Long’s areas of expertise is the treatment of hypospadias, a condition in which the penis has not formed normally. He has been selected to participate on a national committee designed to improve the care of boys with this condition. Much of Dr. Long’s current research focuses on hypospadias surgery and improving the experience of boys and men who have this condition.
“Our studies have identified the best approach towards treating boys with the most severe forms of hypospadias. Our studies have the largest number of patients from a single hospital in the world, and this experience will continue to improve the outcomes for our patients,” he explains. “We continue to raise the bar by improving the care delivered to our patients. This has spanned over many years and includes how patients are assessed in the office, standardizing our efforts across surgeons in order to decrease the variability in care delivery, and the duration of follow up. We are always pushing to improve the outcomes for our patients.”
Dr. Long’s research and experience treating hypospadias has led him to share the work being done at CHOP in presentations at several national and international meetings, including Moscow, Cairo and Frankfurt. In 2019, CHOP hosted the international meeting in Philadelphia, with over 250 guests discussing the latest trends in hypospadias management.
The international efforts extended beyond meetings. Dr. Long has led an annual surgical trip to Trinidad, where there is a large number of boys with uncorrected hypospadias.”
“Because there are so few pediatric urologists in the world, there is a great need for our services as well as an opportunity to share our experiences with other surgeons,” he says.
He also treats patients with neurogenic bladder related to spina bifida or other disorders of the spine. These patients are seen at birth and followed through adulthood.
“I really enjoy the lasting relationships I can develop with these families,” says Dr. Long. “I first meet them as newborns and get to see them grow into adults, working to make sure their kidneys are safe and they achieve urinary continence. A special bond is formed with families whose children have spina bifida.”
Dr. Long has been active in other areas of pediatric urology including complex reconstruction, minimally invasive surgery and oncology. He performs minimally invasive procedures using laparoscopic and robotic surgery.
“I really enjoy seeing the benefits my patients receive from an operation performed through smaller incisions,” he notes. “We are one of the few centers in the U.S. able to perform these complex operations through incisions as small as a half a centimeter. This provides us with a unique view of the child’s anatomy which really allows us to achieve a successful operation. It also results in a smoother recovery.”
“At CHOP, we dedicate a lot of our time and resources towards constantly improving the care we deliver to patients and their families,” he says, noting that the future of pediatric urology continues to evolve and improve. “As a national leader, we set the bar for patient improvement.”
Advances in personalized medicine will continue to push the envelope in patient care and improve outcomes. Individualized medicine and personal care are part of an approach that connects Dr. Long with patients and families and helps them reach the best possible health outcomes.
”I think patients will undergo very focused blood and urine tests, genetic screening, and possibly even new imaging tests that will identify anatomic concerns for a unique course of action and improve the outcome of their disease,” he says. “We are already using images from MRI scans to print 3-D models to personalize and improve our surgical approach for several procedures in patients with very abnormal anatomy. I expect this will be applied across even more diagnoses over time and will help to further individualize care.”
“As we continue to push toward discovering better approaches to our patients we also are driven towards education,” he says. “As an academic center, we are driven to objectively record the art of surgery into elements that allow for comparison across patients. Monitoring trends in these variables in our surgical techniques and anatomic variations that may be modified to ensure a more successful operation. This is how we push to deliver groundbreaking care for hypospadias, urologic oncology, neurogenic bladder, and our minimally invasive techniques. This does create extra work as we monitor not only our own individual progress but our entire group. It also facilitates transition of knowledge to our resident and fellow teams as we train the next generation of surgeons, a core element of our mission at CHOP urology.”
