Laparoscopic-assisted cystotomy and cystostomy for treatment of cystic calculus in a gelding

Objective: To report laparoscopic-assisted cystotomy and inguinal cystostomy for treating 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 to remove the calculus. During withdrawal, the calculus fragmented into multiple pieces. To avoid urethral occlusion and facilitate elimination of these fragments, an inguinal cystostomy was created. The seromuscular layer of the bladder was circumferentially secured to the abdominal fascia and bladder mucosa margins were sutured to the skin.

Results: At 2-year follow-up, the gelding was in good condition with mild urine scald of the left ventral abdomen.

Conclusion: Laparoscopic-assisted cystotomy was used for calculus removal and inguinal cystostomy for successful fragment elimination.
