Inguinal rupture with herniation of the urinary bladder through the scrotal fascia in a Shetland pony foal

Summary Herniation of the urinary bladder in the inguinal region has not previously been described in the horse. A case of inguinal rupture with herniation of the bladder through the scrotal fascia in a 3-month-old Shetland pony, diagnosed by external palpation, urinary catheterisation and external ultrasonographic examination is reported. Surgical management of the case was by dissection of the scrotal fascia, partial cystectomy and unilateral castration. During the period of hospitalisation the only complication was a slight seroma, which resolved spontaneously. Follow-up after 6 months did not reveal any abnormality.
