Abstract

Specific congenital malformations of the spine are consistently associated with characteristic types of urinary tract malformation. Patients with defects of the spine such as spina bifida occulta, partial or complete absence of the sacrum, unilateral or bilateral failure of segmentation, and wedged vertebrae are not usually associated with congenital urinary tract malformations. Spina bifida and myelomeningocele have a low incidence of urinary tract abnormalities (2.1% in this study). If there are other spine abnormalities associated with spina bifida, the incidence or urinary abnormalities increase 10 times. However, hemivertebrae occurring alone in patients or occurring in conjunction with other anomalies of the spine, are most frequently associated with urinary tract abnormalities (66%). Hemivertebrae of the low cervical and upper thoracic spine carries the highest incidence of associated urinary tract malformation.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
