Kidney, Bladder, Pelvis and Testicle Tumor Program

A close-up of a boy with dark brown hair and wearing a gray shirt.The Urologic Tumor Program at Children's Hospital Colorado specializes in the diagnosis and surgical treatment and/or removal of benign (non-cancerous) and malignant (cancerous) tumors of the kidney, bladder, pelvis and testicles in children, teens and young adults.

Children’s Colorado is the only hospital in the Rocky Mountain region with a specialized team of experts dedicated to the care and treatment of urologic pediatric tumors of the kidney, bladder, pelvis and testicles.  

Surgeons in the Urologic Oncology Program successfully perform minimally-invasive surgery (laparoscopic and robotic-assisted surgery), as well as, organ-sparing surgery (partial nephrectomy and partial orchiectomy) as part of treatment for tumors. Minimally-invasive surgery allows shorter recovery times for patients, whereas organ-sparing surgery saves the function of a kidney or testicle by only removing the part of the organ that is affected by the tumor.
