A six-week-old male Shetland pony is presented with pollakiuria and a
scrotal mass. The diagnostic procedures conducted included a thorough
clinical examination, external palpation, a scrotal ultrasonographic
exam and urinary catheterization. These revealed an indirect herniation
of the urinary bladder into the tunica vaginalis. Subsequently, the case
was managed surgically by performing a partial cystectomy through an
inguinal approach. Bilateral castration was performed with the affected
side an additional closure of the superficial inguinal ring. Five months
post-surgery, a routine telephone questionnaire highlighted no
post-operative concerns. Gross examination of the inguinal region
revealed no abnormalities and the foal was maturing as expected.
