A 12-year-old stallion was evaluated because of pollakiuria; endoscopy of the urinary tract during general anesthesia revealed that the urinary bladder was intact. After recovery, the stallion developed clinical and biochemical signs of bladder rupture, which was confirmed by endoscopy. Cystoplasty in adult stallions represents a unique surgical dilemma; the large distance between the incision site and the bladder necessitates the repair be accomplished under maximum tension with minimal exposure. Because traditional surgical approaches through ventral midline or paramedian incisions provide limited access and viewing, laparoscopy was used to provide a definitive diagnosis, good viewing, easy access, tension-free dissection, and a secure repair. Lack of surgical complications and postoperative discomfort, rapid and uncomplicated healing, and patient-client satisfaction make laparoscopic cystoplasty the preferred method for surgical repair of ruptured urinary bladder in adult stallions.

Results indicate that PSGAG is distributed to the SDFT, serum, and urine after IM administration in rabbits. Further study is needed to determine whether the same is true in horses and to determine what effect, if any, PSGAG has on inflammation of the SDFT.
