Dana A. Weiss, MD, is an attending pediatric urologist in the Division of Urology at Children’s Hopsital of Philadelphia. She is also a staff urologist at the Hospital of the University of Pennsylvania and an Assistant Professor of Surgery in Urology at the Perelman School of Medicine at the University of Pennsylvania.

Dr. Weiss’ top priority is to make sure her patients and families feel comfortable and completely understand the assessment and plan at each visit. She encourages open conversations in her practice to ensure this. When it comes to surgery, she makes sure families are aware of all the risks and benefits of treatment so they know exactly what will take place. Through this process, she loves getting to know her patients and caring for them over time.

Dr. Weiss is passionate about treating a variety of urologic conditions and anatomic defects that require reconstruction. She studies and treats bladder exstrophy, neurogenic bladder, other bladder ureteral and kidney abnormalities, and hypospadias in the Division of Urology.

Dr. Weiss earned her medical degree from the Yale School of Medicine and then completed a residency in Urology at University of California San Francisco. She first came to CHOP in 2012 as she continued her urologic training with a fellowship in Pediatric Urology. In 2014, Dr. Weiss joined the Division of Urology at CHOP as an attending urologist.

Dr. Weiss’ research is focused on several areas, including bladder exstrophy and neurogenic bladder, among other projects. She is the director of research for the CHOP team within the Multi-Institutional Bladder Exstrophy Consortium, and has led studies on continence outcomes. She is working on developing research methods to create a continence grading scale that is more useful to patients and families.

Dr. Weiss is also working on radiographic and 3-D modeling of the pelvis to provide greater insights into surgical repair. She participates in a yearly trip to Ahmedabad, India, led by colleague Aseem Shukla, MD, where she is involved in analyzing the outcomes of a large cohort of patients and plans to study the genetic associations of bladder exstrophy. In addition, she has created a biorepository of urine and is working with the CHOP Proteomics core to investigate biomarkers for high-risk bladders in children with spina bifida. Her ultimate goal is to understand how the condition affects all aspects of the lives of patients and improve treatment outcomes.

In addition to clinical work and research endeavors, Dr. Weiss strives to create a valuable and fun education experience for all residents, fellows and medical students rotating through CHOP. In her time at CHOP, she has mentored more than 27 residents and fellows. She still believes in the Socratic method, asking probing questions to promote careful thought about each step in patient care. She actively teaches with hands-on interaction in the OR, demanding technical excellence while providing anecdotes and tales of adventures and misadventures that are key to avoid. On the floor with patients and ER consults, she learns about the patients in partnership, paying prompt attention to the pertinent details and encouraging the in-depth assessment of each patient condition. These efforts have been recognized by the residents, as she was the recipient of the 2020 MAGPI (Mentorship and Guidance in Physician Improvement) teaching award.
