Laurence Baskin, M.D.

Chief of Pediatric Urology

Dr. Laurence S. Baskin is chief of Pediatric Urology and an expert in genital development and reconstructive surgery. He specializes in treating urological conditions in children including hypospadias, urinary tract reconstruction, adolescent varicoceles and genitourinary malignancies. He is the founder of the Center for the Treatment and Study of Hypospadias, a center that focuses on a congenital defect of the penis that results in incomplete development of the penile urethra.

Baskin earned a medical degree at the University of California, Los Angeles, followed by general surgery training and residency at UCSF Medical Center. He completed a fellowship in pediatric urology at Children's Hospital of Philadelphia. He has participated in humanitarian surgical trips to San Pedro Sula, Honduras and Saigon, Vietnam. He is the primary author on more than 200 research articles and is editor of the Handbook of Pediatric Urology and Hinman's Atlas of Pediatric Urologic Surgery. He is the president of the Society of Pediatric Urology; an active member the American Academy of Pediatrics and American Urological Association; he is a fellow of the American College of Surgeons; and past president of the Society of Fetal Urology and Society of Genitourinary Reconstructive Surgeons.
