    abstract = "Despite being formally included in the assessment of patients presenting
with lower urinary tract symptoms (LUTS), transrectal ultrasonography
(TRUS) is not routinely offered to these patients. This tactic however
might not be optimum since data exist on the superiority of TRUS over
transabdominal ultrasound in accurately predicting prostate volumes. We
aimed to evaluate TRUS as a standard tool in the evaluation of patients
with benign prostate hyperplasia (BPH) with a special focus on the
potential impact it might have on the decision of open versus
transurethral surgery.
Seventy-one patients presenting with LUTS due to BPH and eventually
managed with open surgery based on their preference and prostate volume
were included in the protocol. TRUS was performed in all patients
preoperatively and calculations of the transition zone were made. These
were compared with respective transabdominal calculations of the
prostate volume as well as the enucleated specimen weight (W).
TRUS slightly underestimated W by 4.4% (95% CI 10.5, 1.7) while
transabdominal ultrasound overestimated it by 55.7% (95% CI 31.8,
79.6). Regression analysis indicated TRUS as a better predictor of W (R
(2) = 0.817, P < 0.0005) followed by transabdominal ultrasound (R (2) =
0.669, P < 0.0005). Strictly based on European Association of Urology
(EAU) criteria, transabdominal measurements miscategorized 25 cases by
falsely assigning them to the open surgery (> 80 cc) group while TRUS
did so for four cases.
TRUS is more accurate than transabdominal ultrasound in predicting
adenoma volume in patients with BPH and its standard use might lead to
fewer open approaches, with consequent less morbidity and
hospitalization."
