Researchers conducted this study to assess preoperative ultrasonography precision (US)-determining the prostate volume and proposing formulas for improving it.
The present retrospective study comprised 155 consecutive men who underwent open prostatectomy for BPH. Preoperative prostate volume was estimated by either the abdominal US or the transrectal US.
The median prostate volumes by AUS and TRUS were 140 ml and 108 ml, respectively. Enucleated tissue weight was lower than the AUS assessment by a median difference of 50 g and lower than the TRUS assessment by a median difference of 27 g. Mathematical calculations revealed two formulas that significantly adjusted for the actual weight: 1.082*Age + 0.523*AUS − 53.845 for AUS and 0.138*age + 2.22*prostate-specific antigen + 0.453*TRUS + 11.682 for TRUS. These formulas increased the overall US prostate volume accuracy from 65% to 85%.
Assessment of prostate volume by the US is imprecise for performing a simple open prostatectomy for BPH. Our novel formulas may enhance the stratification of patients with prostatic enlargement to a more optimal surgical approach. Future studies in larger cohorts are needed to substantiate our results.
