Challenges in pediatric urologic practice: a lifelong view.


The role of the pediatric urologic surgeon does not end with initial reconstructive surgery. Many of the congenital anomalies encountered require multiple staged operations while others may not involve further surgery but require a life-long follow-up and often revisions. Management of most of these disorders must extend into and through adolescence before transitioning these patients to adult colleagues. The primary goal of management of all congenital uropathies is protection and/or reversal of renal insult. For posterior urethral valves, in particular, avoidance of end-stage renal failure may not be possible in severe cases due to the congenital nephropathy but usually can be prolonged. Likewise, prevention or minimization of urinary tract infections is important for overall health and eventual renal function. Attainment of urinary continence is an important goal for most with a proven positive impact on quality of life; however, measures to achieve that goal can require significant efforts for those with neuropathic bladder dysfunction, obstructive uropathies, and bladder exstrophy. A particular challenge is maximizing future self-esteem, sexual function, and reproductive potential for those with genital anomalies such as hypospadias, the bladder exstrophy epispadias complex, prune belly syndrome, and Mullerian anomalies. Few endeavors are rewarding as working with children and their families throughout childhood and adolescence to help them attain these goals, and modern advances have enhanced our ability to get them to adulthood in better physical and mental health than ever before.

John Samuel Wiener

Professor of Urology

As a general pediatric urologist, Dr. Wiener is involved with all aspects of pediatric urology as a clinician and researcher.  His research interests are most focused, however, on the urologic management of neurogenic bladder and spina bifida and the molecular biology involving development of the genitourinary tract and disorders.

Dr. Wiener is the principal investigator at Duke for The National Spina Bifida Patient Registry and Urologic Management of Young Children with Spina Bifida protocol administered by the Centers for Disease Control and Prevention.  These projects began at Duke in 2011 and 2015, respectively.

Dr. Wiener was previously a project director for the P50 Center for Undiagnosed Pediatric and Urogenital Disorders.

Dr. Wiener has served in national leadership positions in pediatric urology including President of the Society of Fetal Urology, Executive Council of Society for Pediatric Urology, and the Examination Committee of the American Board of Urology.  He is currently on the Board of Directors of the Spina Bifida Association
