Novel ultrasound-based volume estimation of prostatic benign enlargement to improve decision-making on surgical approach.

ABSTRACT:

Aim

To assess the precision of preoperative ultrasonography (US)-determined prostate volume and to propose formulas for improving it.

Methods

This retrospective study comprised 155 consecutive men who underwent open prostatectomy for benign prostatic hyperplasia (BPH) between 2013 and 2019. Preoperative prostate volume was estimated by either abdominal US (AUS) (n?=?92) or transrectal US (TRUS) (n?=?63), and was compared with the weight of surgically enucleated tissue at a conversion rate of 1?ml (US)?=?1 g tissue. Statistical analysis was conducted and a novel formula for prostate volume was constructed.

Results

The median prostate volumes by AUS and TRUS were 140?ml [interquartile ratio (IQR) 111-182] and 108?ml (IQR 93-120), respectively. Enucleated tissue weight was lower than the AUS assessment by a median difference of 50?g (IQR 28.7-75.7; p?p?p?ConclusionAssessment of prostate volume by US is imprecise for decision-making of whether to perform open simple prostatectomy for BPH. Our novel formulas may enhance stratification of patients with prostatic enlargement to a more optimal surgical approach. Future studies in larger cohorts are needed to substantiate our results.
