    Objectives: National guidelines recommend obtaining prostate gland volume (PGV) prior to benign prostate hyperplasia (BPH) surgery. Measurement of PGV with handheld ultrasound (HUS) probes shows promise. Objective: to compare reliability of two HUS probes (Butterfly IQ, Clarius C3) to BPH guideline recommended imaging (GIm) for both prostate and bladder volumetrics. Methods: Male patients with GIm were randomized to undergo transabdominal HUS PGV with one of the two probes. A subset underwent voided volume measurements with one of the two HUS and a conventional bladder scanner (BS). Reliability of the volume measurements was assessed for each probe via intraclass correlation coefficients (ICC). We utilized the following standard criteria: ICC < 0.5: poor reliability; 0.5 ≤ ICC < 0.75: moderate reliability; ICC ≥ 0.75: good reliability. Results: 78 men in the prostate arm (38 Butterfly, 40 Clarius) and 45 in the bladder arm (24 Butterfly, 21 Clarius) were randomized and included in this study. The mean prostate volume based on GIm was larger in the Clarius group (p=0.044). Other baseline characteristics were similar between groups (p>0.05). The ICCs were 0.78 (95% CI: 0.62, 0.88) and 0.71 (95% CI: 0.51, 0.83) for the Butterfly and Clarius probes, respectively. Regarding bladder volumetrics, the ICCs were 0.82 (95% CI: 0.19, 0.95), 0.72 (95% CI: 0.44, 0.88), and 0.69 (95% CI: 0.13, 0.87) for the Butterfly, Clarius, and bladder scanner, respectively. Conclusions: The Butterfly IQ demonstrated good reliability for PGV and voided volume measurements, in comparison to moderate reliability for Clarius C3.
