This question was provided by Manson Publishing as part of the OVAL Project. See more Small Animal Soft Tissue Surgery Q&A. |
The figure shows an eight-year-old male dog at exploratory surgery. The mass adjacent to the bladder was thin walled and filled with clear yellow fluid. There were several adhesions to the prostate, but an anatomic communication with the gland was not identified.

| What are the surgical treatments for this abnormality, and what are the advantages and disadvantages of each? | Cysts resection is curative if the origin is identified. Disadvantages include more extensive prostatic manipulation needed to identify the origin of the cyst and recurrence in the case of inadequate resection. A recent report described good success using omentalization of the cyst remnant after subtotal resection.
Disadvantages include difficulty in mobilizing the cyst to reach the abdominal wall and prolonged drainage.
