Our incredible clinical psychologist

Cortney Wolfe-Christensen, Ph.D.

Cortney Wolfe-Christensen, Ph.D., is a psychologist with Cook Children's Urology/Genitourinary Institute. She works with children, teens and families who are affected by genitourinary conditions.

Wolfe-Christensen offers behavioral help for children with voiding dysfunction (problems going to the bathroom) and other conditions. She also offers psychological support and therapy for parents of children with genitourinary conditions, including differences in sex development. She believes an essential part of her work is to help parents understand their child's diagnosis and become comfortable with it. Dr. Wolf-Christensen knows that children do best when their parents are comfortable with their condition and treatment. She also enjoys serving as a patient and family liaison for the program, to help patients and families understand all aspects of children's condition and care.

In addition to providing support and care to patients and families, Dr. Wolfe-Christensen does research on:

  • The psychosocial difficulties of children with voiding dysfunction
  • How parents and children adjust to a disorder of sexual development

She has published more than 50 articles in peer-reviewed journals, including the Journal of Urology, the Journal of Pediatric Urology and the Journal of Pediatric Psychology. The National Institutes of Health recently awarded her funding to develop an intervention to help parents cope when their child is born with atypical genitalia.

Dr. Wolfe-Christensen received her bachelor's degree in biopsychology and cognitive science from the University of Michigan and received her master's and Ph.D. degrees in clinical psychology from Oklahoma State University. She completed an internship in pediatric psychology and a fellowship in neuroimaging at the Children's Hospital of Michigan.

What is genitourinary?

Genitourinary refers to the genitourinary system which is made up of the genital and urologic organs and parts of the body. Pediatric Urology at Cook Children's focuses on conditions of the kidneys, renal system, pelvis, bladder, urethra, ureter, penis and vagina.

Cook Children's Pediatric Urology specializes in providing advanced care for newborns, infants, children, teens, and young adults with genitourinary conditions. We treat a wide variety of diagnoses, some of them very rare and requiring unique services such as robotic surgery and our clinical research in urodynamics.

  • Hypospadias
  • Undescended testicles (UDT)
  • Hernias/hydroceles
  • Urinary tract infections
  • Incontinence/bedwetting
  • Bowel and bladder dysfunction
  • Vesicoureteral reflux (VUR)
  • Kidney stones
  • Hydronephrosis
  • Genitourinary tumors
  • Ambiguous genitalia
  • Disorders of sex development (DSD)

Advanced technology

At Cook Children's our goal is to constantly improve the care we deliver to our patients. To keep that commitment we provide the absolute latest technology and treatments available. Today that means making complicated surgeries simpler, so kids can get better, heal faster, and be home quicker.

The da Vinci Xi Surgical System provides minimally invasive surgery, but the robotic technology also allows the surgeons performing the procedure the latest in technology to operate the precision control system.

Performed by our renowned urology robotic surgical team, the surgery itself looks like a cross between the latest in futuristic robot technology and the coolest video game you could ever play. The surgeon sits in a chair and looks into a screen that looks similar to what people wear to play a virtual reality game. Using the video screen and a gloved device the surgeon directs the robot arm to deliver the most precise and meticulous operation possible.

Along with the precision of the surgery itself, the minimally invasive procedure reduces much of the pain and many complications associated with open procedures surgeons usually perform. This means safer surgeries, with much faster recovery times for the kids we see.

An amazing advancement for surgery, the da Vinci Xi robotic technology allows us to provide minimally invasive surgery on any number of procedures, ranging from the most routine to the most complex cases.

Of course, no surgery seems routine when it is your child. But because the surgery is minimally invasive, we are able to return your children home more quickly than most parents ever thought possible—sometimes as early as the same day or the next day. At Cook Children's, our goal is to return your child back to being a kid as quickly as possible.

Exceptional network of care

When it comes to your child, you want the best care possible. Our team of genitourologists has undergone rigorous education and training in pediatrics, urology, and other related specialties. Many of them are also noted educators and pioneers in research.

Because of its complexity, the genitourinary system often affects other systems in the body. This means your child may be seen by other pediatric specialists such as: a urologist, nephrologist, neonatologist, perinatologist, pediatrician, surgeons, transplant surgeons, geneticists, endocrinologists, neurologists, neurodevelopment specialists, psychologists, nutritionists and/or dietitians and social workers. You and your child also have access to variety of patient and family support such as our Child Life specialists and parent mentors.
