Unilateral renal agenesis associated with multiple skeletal abnormalities

Two cases are presented in which an association between unilateral renal agenesis and multiple skeletal abnormalities is found. The pathologic agents responsible for the URA act similarily on other organ systems, including the skeleton. The skeletal abnormality can be diagnosed easily and promptly and may be an indicator for anomalies in other systems as well, especially the urogenital system.
