Plain-English summary
A group of 24 healthy male dogs were examined to see how accurately a new ultrasound device could measure their bladder volume without needing a catheter. The device, called the BladderScan Prime Plus, was tested by both an experienced and a novice operator. Results showed that while the device generally provided good estimates, there were some differences based on who was using it and the settings chosen. Overall, the device was found to be a useful tool for measuring bladder volume in dogs over 5.5 kg, but results may vary slightly depending on the operator.

Abstract
BACKGROUND: The BladderScan Prime Plus (BPP; Verathon, Bothell, Washington) is an application-specific, three-dimensional ultrasound device used for human, point-of-care volumetry of the urinary bladder. OBJECTIVE: To estimate the BPP's accuracy, repeatability, and optimized settings for assessing urinary bladder volumes in dogs, a variable utilized in assessing micturition disorders. ANIMALS: Twenty-four, client-owned, healthy, male dogs presenting for routine examination. METHODS: Prospective examinations were conducted by an experienced ultrasonographer and a novice, selecting the BPP's "man" or "child" setting, and were compared to urine volume obtained by catheterization. RESULTS: Mean urine volume significantly varied by operator (P = .05), device setting (P < .001), and weight (P = .01); the "man" setting produced mean volumes nearer to catheterized volumes. The mean difference between BPP's "man" setting and catheterized volume was 0.88 mL, with maximal positive and negative disagreement of +23.2 mL to -55.3 mL (SD 19.0). Percent disagreement between BPP and catheterized volumes demonstrated a mean of -4.5%, with maximal positive and negative disagreement of +58.1% to -74.1% (SD 34.9). The experienced operator recorded volumes significantly (P = .05) higher than the novice, with difference in means of 3.2 mL. In dogs weighing >5.5 kg (n = 18/24), mean difference between BPP's "man" setting and catheterized measurements, regardless of operator, was not significant. CONCLUSIONS: Although small magnitude interuser variability is present in BPP examinations, the device provides accurate, though imprecise quantification of bladder volume in canids weighing >5.5 kg.
