  • Residency: New York Medical College Affiliated Hospitals, Westchester County Medical Center, Valhalla, NY
  • Fellowship: Children’s Memorial Hospital, Chicago, IL (pediatric urology and renal transplantation)
  • Clinical interests: laparoscopic surgery and neurology in pediatric urology, urinary incontinence and dysfunctional voiding
  • Israel Franco, MD is a Pediatric urologist with 25 years experience in the field and has been listed in Castle Connolly’s top doctors. He will be directing our new Yale/New Haven Children’s Bladder and Continence Program. Dr. Franco received his medical degree from Albert Einstein College and is fellowship trained At Children’s Memorial Hospital in Chicago, now the Lurie Children’s Hospital. Dr Franco has been an early innovator in laparoscopic surgery and neurourology in pediatric urology. Dr Franco is the treasurer and board member of the International Children’s Continence Society, which plays a vital role in the education of physicians, nurses and physiotherapist in the care of children’s urinary and bowel continence issues. Dr Franco was one of the earliest practitioners of biofeedback therapy in the in the United States and established the paradigm of using nurse practitioners and other physician extenders to help manage the children with urinary incontinence and dysfunctional voiding allowing for extended contact time with caretakers.

    Dr. Franco has been a visiting professor at several prestigious urology programs throughout the country. He has also been an invited professor in Italy, Brazil, China, South Korea, Venezuela, Ecuador and Columbia. Dr Franco has published over 90 articles in peer reviewed journals and has contributed 19 chapters for textbooks with the most recent contributions to Chancellor and Diokno’s textbook on Underactive Bladder in Children and Swaiman’s Neurology: Practices and Principles. He is the lead editor and contributor to a multidisciplinary textbook on Pediatric Urinary Incontinence published by Blackwell Publishing, which was released October 2015.

    Since Dr. Franco’s publication on the Management and Treatment of Overactive in Bladder in Children in 2007 in Journal of Urology he has driven the pediatric community to look at CNS mechanisms as the cause of most incontinence and dysfunctional voiding issues in children. Since that time a more concerted effort to explore these mechanisms has continued to confirm a central role for many children with refractory incontinence.Dr. Franco is involved in clinical research to elucidate the mechanisms of incontinence in children and to find methods to predict incontinence episodes in children with new non invasive technologies.

    Dr Franco has been involved in clinical trials that have lead to the approval of the only anticholinergic approved for use in children and is involved in trials that will hopefully lead to the approval of a new anticholinergic as well Botulimun toxin A for use in children.

    Always an early innovator and on the cutting edge of technology he brings a proven track record of successful innovative therapies to children with neurogenic bladder problems as well as children with non neurogenic bladder and continence issues.

    Dr. Adam B. Hittelman is an Associate Professor of Urology and Pediatrics who specializes in treating children and adolescents with urogenital problems. He is also the Residency Director of Urology. His practice at Yale’s Pediatric Specialty Center is dedicated to accommodating the specific needs of younger patients and their families. “Any surgery on your child, big or small, is always big when it’s your child,” says Dr. Hittelman. To ease the anxiety and strain on parents and caretakers, “we strive to coordinate all of the child’s care in a comfortable, child-friendly environment with as few visits as possible.”

    Because children with complex urologic issues often develop associated medical conditions, Dr. Hittelman works closely with pediatric specialists in multi-disciplinary clinics, improving family access and continuity of care. “I always try to make myself available to parents and families,” he says. “We take the time to ensure that their questions and concerns are addressed and answered to everyone’s satisfaction.”

    Dr. Hittelman earned his MD and a PhD in molecular and cellular biology from New York University. He later completed his residency and fellowship at the University of California, San Francisco, a program renowned for its multidisciplinary approach to training and research in the field of pediatric urology.

    Clinically, Hittelman’s primary focus is in reconstructive surgeries for children born with congenital anomalies like hydronephrosis (swelling of a kidney(s) due to a build-up of urine), primary vesicoureteral reflux (a valve defect that can prevent urine from flowing backward from the bladder into the ureters) and disorders of sexual development (congenital anomalies of the internal and external genitalia). Kidney stones, hypospadias, hydroceles and hernia are also part of his clinical work. He offers traditional and minimally invasive approaches to pediatric procedures, including laparoscopic, endoscopic and robotic-assisted techniques.

    “As technology has improved and instruments are getting smaller, I have been able to apply this to younger and younger patients,” he says. “This has allowed for shorter hospital stays, decreased postoperative pain and smaller incisions.”

    Dr. Hittelman is the author of a large body of peer-reviewed articles and research related to pediatric urologic conditions. He is also an active member of several national medical organizations, including the American Urologic Association, the Society of Pediatric Urology, the Society of Fetal Urology and the American College of Surgeons.

    Dr. Stanton Honig is a nationally known expert on male fertility, sexual medicine and surgery. In his large clinical urology practice, he focuses on providing compassionate, personalized care to men struggling with infertility, sexual problems and gender affirming surgery for male to female, in addition to general urology. This involves working with couples that are having trouble conceiving because of male reproductive issues, such as no sperm in the ejaculate, low sperm counts, or blockage of the vas deferens, the tiny tubes that deliver sperm.

    Dr. Honig has been at the forefront of many groundbreaking techniques in urology, including sperm retrieval techniques, medical and surgical treatment of erectile dysfunction, treatment of peyronie’s disease (curvature of the penis) and unique treatments for low testosterone, vasectomy and testis implants. 

    To provide coordinated care for fertility patients, he works closely with reproductive endocrinologists, doctors who specialize in female fertility issues. “It’s so rewarding to help couples achieve pregnancy, and to improve intimacy in couples,” Dr. Honig says. He often tells patients, “as long as we can find sperm, we can help you to start a family. In cases of erectile dysfunction, we can help everyone! It’s just a matter of what treatment you would like to choose.”

    Dr. Honig has more than two decades of experience in microsurgery and is the most experienced fellowship-trained urologist in microsurgery, male reproduction and sexual medicine in Connecticut. He is the past president of the Society for the Study of Male Reproduction (SSMR), a sub society of the American Urological Society. He is currently on the American Urology Association’s (AUA) Vasectomy Guidelines Committee, Center for Disease Control’s (CDC) Male Infertility Working Group and the Male Reproductive Health Alliance.

    Dr. Honig regularly presents at the AUA’s national meetings on the latest developments in his field, and has served as a reviewer on the editorial board of many peer-reviewed academic journals. He speaks widely, lecturing at conferences, regionally, nationally and internationally. He works to promote public awareness of men’s health issues, specifically addressing issues related to preservation of fertility for cancer patients, testis self-examination, and the prevention of male reproductive health issues and has spoken at the CDC on these topics.

    Mary Grey Maher, MD is board certified in both General Urology and Urogynecology.

    Dr. Maher earned her undergraduate degree at Wellesley College, and her medical degree at Yale University.

She has trained extensively in pelvic floor reconstruction and can offer a range of surgical repairs, customized to the patient’s condition and wishes, including robotic surgery. She provides innovative, and high quality care to help patients regain function and improve their quality of life.
