Umbilical evagination of the urinary bladder in a neonatal filly.

This research article explores a unique case where an 8-hour-old Standardbred filly exhibited an unusually large umbilical mass and difficulties in urination, which was confirmed as an abnormality of the urinary bladder growing through the umbilical stalk. The issue was rectified through surgical procedures and resulted in a good clinical outcome for the filly.

Case Introduction

• The article begins with a brief introduction of an 8-hour-old Standardbred filly, which was brought under examination due to an enlarging umbilical mass and stranguria, a condition marked by slow and painful urination.

Surgical Investigation

• The researchers suspected the umbilical mass as the urinary bladder and confirmed it upon surgical exploration of the filly’s abdomen.
• Despite the filly having a normal umbilical ring, the bladder had descended and partially everted through its urachal communication with the umbilical stalk, a quite rare and unique situation. This condition is referred to as ‘evagination of the urinary bladder’.

Surgical Rectification

• To rectify the situation, partial cystectomy (partial removal of the bladder) and umbilical resection (surgical removal of the umbilicus) were performed.
• These surgical interventions proved successful and resulted in an excellent clinical outcome for the filly, implying a significant improvement in its health and wellbeing following the procedures.

Discussion on Rarity of the Case

• In the closing discussion, the researchers highlight the rarity of the case. Evagination of the urinary bladder via the umbilicus has been infrequently described in human infants; furthermore, according to the authors’ awareness, it has not been previously reported in veterinary literature.
• This rare occurrence, detailed insight, and successful resolution provide a valuable contribution to the repertoire of veterinary literature and surgical practice.
