Urogenital: rectal palpation

pequis

Introduction

Uses

  • Rectal examination of horses allows examination of approximately one-third of the abdominal cavity.
  • Investigation of:
    • The reproductive cycle in mares, and disease of the urogenital system in mares, stallions and geldings.
    • Gastrointestinal disorders, particularly colic Abdomen: pain - adult.
    • Cases where a pelvic fracture is suspected Pelvis: fracture.

Advantages

  • Non-invasive, simple, cheap, and useful technique.
  • Easily performed on farm.
  • Allows surface palpation of organs that cannot be imaged by percutaneous ultrasonographic examination.
  • Three-dimensional assessment of the shape and position of those organs (whereas 2D ultrasonography and radiography are limited to images in two dimensions).
  • Assessment of the texture of the organs, as well as their shape and position.

Disadvantages

  • Rectal tears Rectum: tear.
  • Limited to caudal abdomen.
  • Injury to the handler or veterinarian is not uncommon.
