Keys to the diagnosis of occult urologic disease in children.

All physicians who care for children should be aware of the many indications for further urologic examination. A straightforward algorithmic approach to urologic diagnosis is not possible. The physician must individualize and carefully weight the indications for the often-times expensive and uncomfortable tests that are required for urologic diagnosis. The reward is ample when a significant correctable lesion is recognized early enough for salvage on the basis of seemingly unrelated signs or symptoms.
