Maternal exposure to diethylene glycol monomethyl ether: a possible role in the etiology of retrocaval ureter.

Retrocaval ureter is a very rare condition. In light of the experimental studies, one of the etiologic factors seems to be maternal contact with diethylene glycol monomethyl ether or ethylene glycol monomethyl ether. A case of cardiovascular, skeletal, and retrocaval ureter anomalies caused by possible maternal contact while pregnant with these materials at her work in a textile factory is presented.
