title: [Diagnosis and follow-up of benign prostatic hyperplasia by ultrasound].
abstract: OBJECTIVE
  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.
