[Superior vesical fissure]

Although vesical extrophy is a well-known anomaly, the variants of vesical extrophy are exceptional. We present the case of a newborn child, who upon exploration, revealed a defect of closure in the infra-umbilical abdominal wall through which vesical mucous membrane protruded. A probe introduced into the urethra appeared externally at the place of the infraumbilical defect. Following the diagnosis of superior vesical fissure, resection of the protruding vesical mucous membrane and closure were carried out. The authors reviewed the bibliography published in order to study the different kinds of variants of vesical extrophy and the associated congenital anomalies. Although these children are usually continent, a urodynamic study and a VCU are recommended in order to discard the existence of a post closure-uretheral-vesical reflux of the umbilical defect.
