  • Title: Pyourachus: study of two cases.
    Author: Thapar RB, Jha VU, Mehta RU, Shah GR.
    Journal: Br J Radiol; 2006 Jul; 79(943):e1-4. PubMed ID: 16823045.
    Abstract:
    The urachus, or median umbilical ligament, is a midline tubular structure that extends upward from the anterior dome of the bladder toward, the umbilicus and represents the vestigial remnant of at least two embryonic structures, the cloaca and the allantois. The tubular urachus normally involutes before birth, remaining as a fibrous band, however its persistence can give rise to various clinical problems, not only in infants and children but also in adults. We report two cases of pyourachus at our institute with a review of the clinical presentation, imaging findings and surgical management. Both our patients were young males, with haematuria being the presenting feature in one case which has not been previously described in literature.
