Accuracy of Clarius, handheld wireless point-of-care ultrasound (POCUS), in evaluating prostate morphology and volume compared to radical prostatectomy specimen weight: Is there a difference between transabdominal versus transrectal approach?

Background: Prostate size estimation is a valuable clinical measure widely utilized in urology. This study evaluated the accuracy of preoperative transabdominal ultrasound (TAUS) compared to radical prostatectomy specimens and transrectal ultrasound (TRUS) in estimating prostate volume and identifying presence of median lobe, across different size groups, using the standard ellipsoid formula.
