Your Comprehensive Care Team

Your child's care team will include every specialist you child might need. They will work with you and your child to determine a treatment plan that considers the impact one treatment might have on another area of the body.

Diagnosis and treatment — what to expect


We provide team-based care that centers on the best possible outcome for your child. We will work with you to create an integrated and personalized care plan specific to your family's needs. 

Depending on your child’s age and condition, we will:

  • Carefully examine your child's symptoms and diagnose any related conditions.
  • Help your child achieve independence with their fecal and urinary control.
  • Provide a second opinion or re-evaluation for children with complex conditions.
  • Coordinate complex, multi-system surgery to correct or reconstruct your child’s anorectal, urological and gynecological systems using the least invasive approach, always keeping your child’s future in mind.
  • Evaluate internationally adopted children with colorectal or pelvic floor conditions in coordination with Children’s Mercy’s International Adoption Clinic.
