Objective:
To describe a method for laparoscopic cystotomy in an alpaca.
Study Design:
Case report.
Animals:
Female alpaca.
Methods:
An 8-month-old female alpaca was admitted with a 6-week history of straining to urinate and vulvar swelling. Transrectal ultrasound examination revealed a 1.5 x 1.5 x 2 cm polyp within the bladder.
Results:
The mass was excised using laparoscopic cystotomy. Leakage from the cystotomy site resolved over 12 days using a Foley catheter. The alpaca was healthy and urinating normally at 9 months after surgery.
Conclusion:
Minimally invasive surgery by laparoscopic cystotomy can be used to remove large urinary polyps in alpacas.
Clinical Relevance:
Urinary bladder polyps should be considered as differential diagnosis in alpacas with stranguria.
