A case of urachal abscess resection via colpotomy in a cow.

This study describes a novel surgical method to remove urinary bladder-related urachal abscesses in a cow. Traditional methods, such as the midline or paramedian approach in calves and the preinguinal approach, can be challenging in adult cattle, especially for lesions situated near the pelvic cavity. In this case, a 4-year-old cow had a urachal abscess attached to the bladder apex, making it difficult to approach via abdominal wall incision. Colpotomy and pulling the abscess through a vaginal wall incision allowed for complete exteriorization of the lesion and comfortable accessibility of the abscess and the resection site. This report suggests that colpotomy is an effective new route in adult cattle for accessing urachal abscesses not accessible via traditional surgical approaches.
