THE PARENTS of a 3-year-old boy sought
consultation regarding a brownish discoloration of their son's clothing and bed
sheets noted after episodes of enuresis. The parents report that the
discoloration became more intense over time. Their son had been healthy and
without other complaints. There was no history of illness or trauma. There were
no urinary tract symptoms. The medical history was unremarkable as was the
family history.
There were no abnormal findings noted on the physical
examination. Urine was obtained for examination. The urine was clear and yellow
in color with a specific gravity of 1.010, pH of 6.5, and without evidence of
hemoglobin, myoglobin, red or white blood cells, or protein. A sample of the
urine was observed at room temperature for 48 hours with the color changes
shown
