Sacral agenesis and associated anomalies.

Sacral agenesis can no longer be considered an uncommon disorder. The condition occurs often enough that the clinician should be alert to any signs that may suggest its presence in a newborn. This disease is frequently associated with other anomalies, especially those of musculoskeletal, GU and GI systems. Diagnosis--early diagnosis--is the key to prevention of permanent damage to the kidneys and urinary tract in patients with the disease.
