Examples

  • The lowest part of the allantoic pedicle (or the "urachus") remains hollow, and forms the bladder.

    The Evolution of Man — Volume 2

  • It also has a narrow canal (the urachus) which serves to remove the urine of the foetus; in fact the subsequently formed bladder takes its origin from a dilation of the urachus.

    The Veterinarian

  • In very rare cases open urachus may exist without any joint inflammation.

    The Veterinarian

  • In this disease, inflammation of the joints and open urachus are almost always co-existent.

    The Veterinarian

  • TREATMENT: In the treatment of this disease, we have to attend to constitutional disturbances, inflamed joints, open urachus and complications such as constipation and diarrhoea.

    The Veterinarian

  • Occasionally foals two or three months old which have the urachus closed and are in an apparently healthy condition contract this disease in a form of painful swelling of the joints.

    The Veterinarian

  • As examples of the former may be mentioned that in which the organ is deficient in front, and has become everted and protruded like a fungous mass through an opening at the median line of the hypogastrium; that in which the rectum terminates in the bladder posteriorly; and that in which the foetal urachus remains pervious as a uniform canal, or assumes a sacculated shape between the summit of the bladder and the umbilicus.

    Surgical Anatomy

  • The vertex of the bladder is joined to the umbilicus by the remains of the urachus which forms the middle umbilical ligament, a fibromuscular cord, broad at its attachment to the bladder but narrowing as it ascends.

    XI. Splanchnology. 3b. 3. The Urinary Bladder

  • The remainder of the vesico-urethral portion forms the body of the bladder and part of the prostatic urethra; its apex is prolonged to the umbilicus as a narrow canal, which later is obliterated and becomes the medial umbilical ligament (urachus).

    XI. Splanchnology. 3. The Urogenital Apparatus

  • There is a case described 6.328 of a man who evidently suffered from a patent urachus, as the urine passed in jets as if controlled by a sphincter from his umbilicus.
