“…The latter occurs because the mare's urethra has a large diameter, and the bladder may be everted into the vagina after severe straining during parturition or associated with colic (Canisso et al, 2013). Prolapse of the pelvic flexure into the bladder has been reported in a mare following perineal laceration repair (Haynes & McClure, 1980).…”

SummaryBladder prolapse is rare in mares but may occur as a result of excessive straining during parturition or postpartum. We report a case of dystocia‐associated prolapse and entrapment of the small colon through the external urethral opening into a prolapsed urinary bladder. No previous reports of this condition were found. An 11‐year‐old Thoroughbred mare was presented to The Equine Hospital of the Jockey Club of Saudi Arabia for evaluation and treatment of dystocia. Prolapse of the urinary bladder was concomitantly diagnosed. After initial assessment, replacement of the urinary bladder in the normal position did not appear possible. The mare was immediately prepared for caesarean section. The foal was successfully delivered and resuscitated. Detailed assessment of the bladder during surgery revealed that the small colon had prolapsed through the external urethral opening and was inside the space formed by the everted bladder. The urinary bladder was opened. The small colon was replaced into the abdominal cavity; a surgeon gently replaced the small colon through the external urethral sphincter and a second surgeon retrieved the small colon by gentle traction until normally aligned. The bladder was closed and replaced. The mare recovered uneventfully. The mare and the foal were discharged from the hospital 17 days post‐operatively.
