Objectives:
The aim of the study is to analyze the utility of ultrasound in the evaluation and treatment selection of patients with benign prostatic hyperplasia (BPH).
Methods:
A total of 5000 patients older than 50 years and with prostatic symptoms were evaluated with abdominal ultrasound and in selected cases with transrectal ultrasound.
Results:
The first ultrasonographic sign of BPH is the increase of anteroposterior and longitudinal diameters. Prostatic volume is measured with a safety of 80%, post-void volume and indirect signs of bladder obstruction are also determined by ultrasound. Upper urinary tract pathological conditions can be also detected.
Conclusions:
Ultrasound associated with PSA and urinary flow are adequate to evaluate and select treatment in patients with BPH.
