Summary
Egg retention in a leopard tortoise
Area of Science:
- Veterinary Medicine
- Herpetology
- Comparative Biology
Background:
- Egg retention, or dystocia, is a critical condition in female reptiles.
- Urinary bladder egg impaction can cause significant health issues in tortoises.
- Accurate diagnosis and effective treatment are vital for successful outcomes.
Purpose of the Study:
- To describe a minimally invasive endoscopic technique for removing a retained urinary bladder egg in a leopard tortoise.
- To document the successful application of a modified polypectomy snare for egg extraction.
- To report the complete recovery of the tortoise post-procedure.
Main Methods:
- Diagnosis of urinary bladder egg retention using radiography.
- Confirmation of diagnosis via cystoscopy.
- Surgical removal of the egg using a flexible endoscope, insufflation, and a modified polypectomy snare.
Main Results:
- Successful removal of the retained egg from the urinary bladder.
- No intraoperative or postoperative complications were observed.
- The leopard tortoise exhibited a full recovery following the procedure.
Conclusions:
- Endoscopic removal of urinary bladder eggs is a safe and effective treatment for tortoises.
- Minimally invasive techniques can resolve egg retention without significant morbidity.
- This approach offers a viable alternative to traditional surgical methods for egg removal.
