Prune-belly syndrome in a 54-year-old man.

A 54-year-old man was diagnosed as having prune-belly syndrome, a deficiency of abdominal musculature, cryptorchidism, abnormalities of the urinary tract, and chronic renal failure. The patient was asymptomatic until the diagnosis was made at the age of 54 years; he is one of the oldest living patients to be reported in detail. Recognition of the syndrome in adults with chronic renal failure is important.
