An Invisible Bladder Stone Causing Silent Obstructive Kidney Failure

Key takeaways

A 60 year old man felt completely fine, but a routine work physical found severe kidney failure and new diabetes. His creatinine, a waste product that rises when kidneys fail, was 6.5 mg/dl, which is very high. The cause was a bladder stone blocking the flow of urine, and it did not show up on a plain X-ray. This is one patient's story, not a study, so it shows what can happen, not how often it happens.
