EXSTROPHY OF THE URORECTAL SEPTUM - REPORT OF 2 CASES AND EMBRYOLOGICAL REVIEW

For the first time two cases of an unusual congenital malformation are described. Both patients had an isolated defect at the median raphe covered by colonic mucosa extending from a hypospadiac urethral orifice to the anal orifice. After a thorough review of the embryology, the authors designate this anomaly as exstrophy of the urorectal septum.
