Surgical management of diffuse polypoid cystitis using submucosal resection in a dog

Area of Science:

• Veterinary Medicine
• Canine Urology
• Surgical Pathology

Background:

• Polypoid cystitis is an uncommon bladder condition in dogs.
• Clinical signs include stranguria, pollakiuria, and hematuria.
• Emphysematous cystitis can coexist with polypoid cystitis.

Observation:

• A 6-year-old spayed female Labrador retriever presented with a 12-week history of urinary signs.
• Diagnosis included bacterial urinary tract infection, diffuse polypoid cystitis, and emphysematous cystitis.

Findings:

• Combined antibiotic therapy and extensive mucosal/submucosal resection led to complete resolution of clinical signs.
• Surgical intervention effectively addressed the polypoid lesions within the urinary bladder.

Implications:

• This case highlights that polypoid cystitis is a reversible condition in dogs.
• Resection of mucosa and submucosa presents a viable surgical alternative to partial cystectomy or simple mucosal resection for treating canine polypoid cystitis.
