Laparoscopy for percutaneous tube cystostomy in dogs

Abstract

Objective: To describe a laparoscopic technique for percutaneous tube cystostomy in dogs. Design: Prospective cohort study. Animals: 8 healthy mixed-breed dogs. Procedures: A laparoscope portal and 2 instrumental portals were created in the abdomen of anesthetized dogs that were in dorsal recumbency. Intracorporeal suturing was performed to place 2 simple interrupted sutures between the ventral body wall and urinary bladder. A purse-string suture was placed in the urinary bladder wall approximately 1 cm cranial to the 2 simple interrupted sutures. A stab incision was made into the urinary bladder in the middle of the purse-string suture; an 8F Foley catheter was inserted through the stab incision and into the urinary bladder. Two other sutures were placed between the ventral body wall and bladder 1 cm cranial to the Foley catheter to create a cystopexy.The Foley catheter was secured to the skin with a finger-trap suture and was attached to a closed urine collection bag. All dogs underwent follow-up laparoscopy 1 month later. Results: Median time for laparoscopic percutaneous tube cystostomy was 85 minutes (range, 72 to 103 minutes); there were no major intraoperative or postoperative complications. On follow-up laparoscopy, focal fibrous adhesions between the ventral body wall and bladder were observed in all dogs and omentum attached to the cystopexy site was observed in 2 dogs. Conclusions and Clinical Relevance: In this study, a laparoscopic percutaneous tube cystostomy was accomplished in healthy dogs by use of a 3-portal technique and appeared to be an effective and safe procedure.
