Pediatric Urology

The Division of Pediatric Urology offers evaluation, medical treatment and surgery for newborns, infants, children and adolescents. Our multidisciplinary team approach utilizes the extensive knowledge and experience of Mount Sinai’s obstetricians, perinatologists, neonatologists and pediatric urologists to manage prenatally detected genitourinary anomalies. Among the many perinatal conditions we treat are: hydronephrosis, posterior urethral valves, ureteropelvic junction obstruction, vesicoureteral reflux, and multicystic dysplastic kidneys. Surgical repairs of common genitourinary anomalies such as hydroceles, undescended testis, hypospadias and chordee are routinely performed during the first year of life. The Mount Sinai team offers the most advanced minimally invasive treatments, often on an outpatient basis. 

Dr. Jeffrey A. Stock is the Director of Pediatric Urology and evaluates and treats children with hypospadias, hydronephrosis and undescended testicles. Dr. Stock has developed several minimally invasive procedures as alternatives to open surgery. He is one of the most experienced urologists in the New York metropolitan area performing robotic-assisted surgery on children as young as eight months old. 

Dr. Grace Hyun is the Associate Director of Pediatric Urology and treats children with a variety of urological disorders, including hypospadias, undescended testicles, acute and chronic urinary tract infections, kidney stone disease, and varicoceles.
