An article about Dr. Atala and his pioneering work in making new bladders out of cells grown from the patient.

Dr. Atala performed this for children and his main focus is in making organs out of a patient's own cells that could be used transplantation.

I can also envision the day when we have bladders available for replacements in patients with bladder cancer, avoiding the need for bowel segments. This would be an excellent thing to have for patients needing cystectomies for bladder cancer, where the entire operation could be performed with robotics.
