Plain-English summary
A 5-year-old spayed female mixed-breed dog was brought in because she had blood in her urine and was straining to urinate. An ultrasound showed a mass in her bladder. To get a sample of the mass, the vet used a special catheter and ultrasound to guide a biopsy tool into the bladder, which allowed them to take a sample without needing surgery. The biopsy results showed she had polypoid cystitis, and she later had the polyp surgically removed without any issues. This method provided a less invasive way to diagnose her condition.

Abstract
A 34.4 kg 5 yr old spayed female mixed-breed dog was presented for evaluation of a urinary bladder mass. The dog had a recent onset of hematuria and stranguria but otherwise appeared to be healthy. Abdominal ultrasound revealed a mass in the urinary bladder. The dog was sedated and a 10-French rubber catheter that had the blunt end removed was passed from the urethra to the urinary bladder. Using ultrasound guidance, ellipsoid cup biopsy forceps were advanced through the rubber catheter to the urinary bladder mass and biopsies were successfully obtained. The dog was discharged from the hospital a few hours after the procedure. Histopathology of the mass was consistent with polypoid cystitis. Follow-up surgical removal of the polyp was uneventful, and histopathology confirmed the presurgical biopsy diagnosis. Procurement of urinary bladder biopsies through a urinary catheter with ultrasound guidance was used as a minimally invasive alternative to either cystoscopy or surgery in a bitch. Use of this technique achieved a diagnosis without the need for specialized endoscopic equipment, anesthesia, or surgery.
