Summary
This study reports the first case of transurethral urinary bladder eversion in a male rabbit. Surgical intervention (cystopexy) was successful, resolving the rare condition.
Area of Science:
- Veterinary Medicine
- Urology
Background:
- Transurethral urinary bladder eversion is a rare condition.
- It has been previously documented in various species, including humans and female animals.
Observation:
- A 7-year-old castrated male rabbit presented with a preputial mass identified as the urinary bladder.
- The condition was diagnosed as complete transurethral urinary bladder eversion.
Findings:
- Exploratory laparotomy and cystopexy were performed to reduce and secure the prolapsed bladder.
- The surgery was successful, with no complications reported for three years post-operation.
Implications:
- This case represents the first documented instance of transurethral bladder prolapse in a male mammal.
- Highlights the importance of considering bladder eversion in male animals with preputial masses.
