Urinary bladder herniation through a vaginal tear in a Rottweiller with dystocia

摘要

A four-year old female Rottweiler presented with a 34-hour history of dystocia. Physical examination revealed a purple-black, fluid-filled sac protruding from the vulva and suspended by a similar colored stalk. Digital vaginal examination indicated that the stalk of tissue extended up into the cervix and beyond. Due to the grossly necrotic appearance, the stalk of tissue was ligated, and the sac was removed. Three puppies were delivered vaginally, but a subsequent caesarian section was required dueto uterine inertia likely secondary to exhaustion. Three more live puppies were delivered via the c-section. Further abdominal exploration revealed a tear in the left vaginal wall, one ligated ureter, and the second ureter free at its distal end and leaking urine into the abdomen. The surgical findings indicated that the bladder, ureters, and urethra had herniated through the vaginal tear and prolapsed through the vulva.
