Laparoscopic-Assisted Cystotomy and Cystostomy for Treatment of Cystic Calculus in a Gelding.

Objective: To report laparoscopic-assisted cystotomy and inguinal cystostomy fortreating bladder urolithiasis in a gelding.Study Design: Clinical report.Animals: Twelve-year-old Appaloosa gelding.Methods: A laparoscopic approach was used to locate and grasp the bladder,which was exteriorized through an enlarged instrument portal for cystotomy toremove the calculus. During withdrawal, the calculus fragmented into multiplepieces. To avoid urethral occlusion and facilitate elimination of these fragments,an inguinal cystostomy was created. The seromuscular layer of the bladder wascircumferentially secured to the abdominal fascia and bladder mucosa marginswere sutured to the skin.Results: At 2-year follow-up, the gelding was in good condition with mild urinescald of the left ventral abdomen.Conclusion: Laparoscopic-assisted cystotomy was used for calculus removal andinguinal cystostomy for successful fragment elimination.[...]
