Question

Which organ obtained from a cadaver is not used for transplantation?

• A. Blood vessel
• B. Lung
• C. Liver
• D. Bladder

Hint:

When this organ fails, surgeons rebuild it from the patient's own bowel rather than graft a donor one.

Answer 1

The Correct Option is D

The question asks us to identify the one structure on the list that is never grafted from a deceased donor. To do this, run through each option against real-world transplant practice. Blood vessels are retrieved and stored as vascular conduits and are used as grafts when a patient needs a bypass, so they are transplantable. Lung transplantation is an established treatment for end-stage lung disease such as cystic fibrosis, COPD and pulmonary fibrosis, so the lung is transplantable. The liver is among the most frequently performed solid-organ transplants worldwide and is life-saving in fulminant hepatic failure and cirrhosis, so it too is transplantable. That leaves the bladder. Surgeons do not graft a donor bladder; when bladder function or storage is lost, urinary diversion is created from the patient's own intestine (ileal conduit or orthotopic neobladder). Because there is no clinical practice of cadaveric bladder transplantation, the bladder is the correct answer.
