Urinary tract involvement in EEC syndrome: a clinical study in 25 Brazilian patients.

We have evaluated 25 patients (14 isolated and 11 familial cases) with the EEC syndrome for genitourinary (GU) tract anomalies through intravenous pyelogram (IVP), voiding urethrocystography, and sonographic examination. Fifty-two percent of the patients (7 isolated and 6 familial cases) had involvement of the urinary tract, with no significant difference between isolated and familial cases. The present data seem to reflect the best estimate of the prevalence of genitourinary anomalies in patients with the EEC syndrome.
