Dr. Antoine Khoury
Dr. Antoine Khoury is a pediatric urologist and Professor of Urology at the University of California, Irvine (UCI). He is the Chief of Pediatric Urology and leads the Children’s Hospital of Orange County (CHOC) Children’s Urology Center. Additionally, Dr. Khoury is the Walter R.

At the CHOC Children’s Urology Center, Dr. Khoury participates in several ongoing clinical research projects with the ultimate goal of providing patients and their families with the most current, innovative, and research-based diagnostics and care. His role as a bladder, ureter and kidney specialist in Orange County, CA is a vital piece of the CHOC Children’s Urology Center team.

Part of Dr. Khoury’s role involves providing support for patients suffering from exstrophy of the bladder, a complex combination of disorders that occur during fetal development. In this condition, the bladder and its other structures are on the outside of the body. This condition involves the urinary tract, muscles and bones, and the digestive system, so a dedicated team of professionals is essential. The team at CHOC Children’s Urology Center understands how this condition can be overwhelming for families, and Dr. Khoury has sought to provide thorough and easy-to-understand information.

The treatment that is recommended for exstrophy of the bladder can be based on the patient’s age and medical history, the disorder’s extend and expected course, and the family’s preference. There are often multiple stages of surgical repair that are needed, and the team at CHOC Children’s Urology Center helps to provide families with access to an international support group network and local support groups.

In his role at CHOC Children’s Urology Center, Dr. Khoury is part of a team that is ranked among the top pediatric urology hospitals according to U.S. News and World Report. The focus is on providing patients and their families the latest in treatment options and working together alongside other specialists to provide a complete range of care for all issues relating to pediatric male and female genitalia.

Dr. Khoury obtained his undergraduate degree at Ain Shams University and his medical doctorate at Ain Shams Medical School. He completed his residency training at the University of Toronto and completed his fellowship training in pediatric urology at The Hospital for Sick Children in Toronto under Dr. B. Churchill.

He went on to spend time at the University of Calgary, where he carried out research in biomaterials and infection. This work resulted in several publications, as well as a patent award on the bioelectric mechanism to eliminate bacterial biofilms. To date, Dr. Khoury has been published in 33 book chapters and more than 200 publications and journals. He has delivered over 160 lectures as a visiting professor or invited speaker and more than 250 presentations at national and international meetings.
