Bladder: cystoplasty

Contributor(s): David Moll, Graham Munroe

Introduction

  • Persistent or patent urachus is a common condition of young foals Urachus: patent in which the urachus fails to close spontaneously at, or shortly after birth, thereby serving as a portal for entry of bacteria.
  • Medical treatment is usually effective.
  • Infection of umbilical structures is common in foals and may be due to failure of passive transfer of immunity, poor hygiene, and environmental contamination. Medical treatment may be effective but chronic cases are often poorly responsive.
  • Surgical removal of the urachus and associated umbilial vascular elements (umbilical vein and two umbilical arteries) (cystoplasty) is recommended if medical therapy does not cause resolution in 5-7 days or where internal structures are involved and no external drainage has been established.
