Warren Snodgrass
Warren Snodgrass is a pediatric urologist specializing in the repair of hypospadias, the second most common birth defect. In 1994 he described the tubularized incised plate (TIP) repair of hypospadias, which has become known as the Snodgrass repair and has become the most common approach to repairing most forms of hypospadias. Together with Dr. Nicol Bush, he also developed the STAG repair for severe hypospadias and the Snodbush repair used mainly for reoperations after unsuccessful surgery. Snodgrass is internationally known for his advocacy of evidence-based surgery, and was the editor of a textbook on pediatric urology. He is in private practice near Dallas, Texas.
Biography
Snodgrass received his medical degree from the University of Texas Medical Branch in 1980, and then completed urology residency training at Baylor College of Medicine in 1986. He spent 12 years in private practice with his father, a urologist, in Lubbock, Texas.[1] He worked at Children's Medical Center until 2014, serving as the Chief of Pediatric Urology for 12 years.[2] He was involved in a controversy at UT Southwestern Medical Center in 2013 after he invited two world-renowned surgeons to participate in a teaching conference, unaware that one of them had his medical license revoked.[3]
In 2014, Snodgrass and Nicol Bush left UT Southwestern to establish PARC Urology for complex hypospadias in children and adults, the only practice in North America devoted to hypospadias and related penis birth defects.[4] In 1994, Snodgrass published a description of the TIP repair of hypospadias.[5] The technique has become popularly known as the Snodgrass urethroplasty or Snodgrass technique.[6] The technique became widely employed across the world.[7] In 2011, the Snodgrass technique was described as the dominant procedure for repairing most forms of hypospadias.[8] In 2017, Snodgrass and Bush published the STAG repair, an improvement on older 2-stage graft operations for proximal hypospadias.[9] In 2015, an analysis of all published articles regarding hypospadias since 1945 reported Snodgrass to be the most cited author.[10][11][12]
Snodgrass has lectured and demonstrated surgical techniques internationally to pediatric urologists and surgeons. He established an annual live surgery course broadcast on the World Wide Web to teach surgeons performing hypospadias repair.[13] Snodgrass served as editor of a pediatric urology textbook, Pediatric Urology: Evidence for Optimal Patient Management.[14] In 2015, Snodgrass and his colleague Nicol Bush self-published a surgical textbook entitled Hypospadiology through a charity, Operation Happenis.[15]
At his outpatient center, Snodgrass cares for patients with hypospadias and teaches evidence-based urology to other physicians.[2][16]
Snodgrass published a book describing the fall of Communism in East Germany entitled Swords to Plowshares.[17]
Honors and awards
Snodgrass was awarded honorary fellowship in the Royal College of Surgeons of Edinburgh.[18] He has been designated a U.S. News & World Report Top Doctor.[19] Snodgrass has been listed in Marquis Who's Who.[20] A review of the top 150 influential scientific publications on hypospadias from 1945 to 2013 reported Snodgrass was the most frequently cited author [21] Snodgrass has also been designated a Best Doctor in America and a Texas Super Doctor. He was the Best Reviewer for the Journal of Urology Pediatric Section, and a Top 10 Reviewer for the Journal of Pediatric Urology. Snodgrass has been an invited visiting professor, lecturer and surgeon to over 75 medical conferences in 36 countries.
