Background

Pediatric urologist Gregory Tasian, MD, MSc, MSCE, is dedicated to a practice of compassionate care for children and adolescents. He strives to make sure families know all the available treatment options for their child. And he supports shared decision-making with families when considering alternative treatments.

Dr. Tasian knew he wanted to be a surgeon from the time he was 7 years old. He loved using his mind and hands to “fix” things as a child. It wasn’t until medical school that he discovered that he wanted to become a urologist.

“Urology offers the opportunity to improve the quality of patient’s lives. Whether it be removing a kidney stone that is blocking the flow of urine from the kidney or creating a new bladder to restore function due to congenital abnormalities or cancer. I wanted an area of medicine where I could apply discoveries in research to improve patients’ lives. There are so many opportunities to do this in Urology,” he explains.

In the Division of Urology, Dr. Tasian focuses his clinical efforts on the surgical and medical management of children with kidney stones. He holds the Cheers for CHOP Chair in Clinical Epidemiology of Pediatric Urological Disease and became interested in pediatric kidney stone disease during his residency. As he explains, the condition was once uncommon.

“When I was in medical school in the early 2000s, very few children developed kidney stones. In the last 20 years, the number of youth who develop kidney stones has increased for reasons that are still unclear. My interest, what I am most passionate about, is to understand what is causing this modern epidemic. This understanding will provide insight into how to reduce kidney stone recurrence across a lifespan.”

Advancements in technology are improving surgery for kidney stones. For example, the instruments used for this surgery are becoming smaller. Urology is (and always will be) at the cusp of technological innovation,” Dr. Tasian explains. “This means that we have the opportunity to use new devices and procedures to make surgery more effective, safer and less painful in the future.”

Dr. Tasian’s research group uses a large data analysis, behavioral economics, dietary assessment, and evaluation of urine and stool to discover determinants of kidney stone disease with the goal of translating this knowledge into new treatments for kidney stone prevention. He directs a large microbiome research program that recently published the first evidence that oral antibiotics increase the risk of kidney stones.

His group also analyzes ultrasound of the kidney to discover novel biomarkers of chronic kidney disease progression for children with congenital urologic disease. He collaborates with imaging experts at the University of Pennsylvania to use machine learning to develop automated methods to predict the risk of chronic kidney disease early in life when kidney function is still preserved.

The long-term goal of Dr. Tasian’s research program is to improve the lives of children with nephrolithiasis and congenital urologic disease.

Research Interests

Dr. Tasian's research focuses on two areas: epidemiology and clinical trials in nephrolithiasis (kidney stone disease) among children and adults, and applying machine learning to improve understanding of the pathophysiology, prediction of outcomes and identification of therapeutics in children and adults with benign urologic disease.

As PI of the CHOP/Penn Clinical Center for the NIDDK-supported Urinary Stone Disease Research Network (USDRN), Dr. Tasian co-leads the Prevention of Urinary Stones with Hydration (PUSH) randomized controlled trial, which is examining the effect of behavioral economic approaches to maintain high fluid intake to decrease stone recurrence, and is the first and largest clinical trial in kidney stone disease to include adolescents and adults. Dr. Tasian is also the Director of the Pediatric KIDney Stone (PKIDS) Care Improvement Network. PKIDS is a community of investigators, patients, caregivers, clinicians, industry partners, and payers who generate and apply knowledge that improves outcomes for children with kidney stones at 26 health systems in North America. Dr. Tasian also directs a large microbiome research program that published the first evidence that antibiotics increase risk of kidney stones, particularly for children. His group also discovered that dysbiosis of the gut microbiome is associated with early-onset calcium kidney stones. These studies identified a network of bacteria involved in butyrate production and oxalate degradation that is less abundant in kidney stone formers.

In addition, Dr. Tasian also leads a large NIH-funded program that applies machine learning to complex data to improve the diagnosis, risk stratification, and prediction of treatment responses of children and adults with benign urological disease. He is the Director of the NIDDK P20 CHOP/Penn Center for Machine Learning in Urology, which is automating the measurement of kidney stones and predicting the probability of spontaneous stone passage for children and adults with ureteral stones. His group partners with Yong Fan at Penn to apply deep learning to extract informative features from renal ultrasound and urodynamics tracings to identify children at increased risk of chronic kidney disease progression early in life when glomerular filtration is still preserved. These features, which can be measured in real-time, will identify children who are most likely to benefit from early interventions to preserve kidney function.
