title: Benign prostatic hyperplasia: clinical benefits on Three-Dimensional Ultrasound eXtended Imaging (3D-XI).
abstract: OBJECTIVE
  To prospectively evaluate whether trans-rectal Three-Dimensional eXtended Imaging (3D XI) allows characterization of the prostate gland in cases of isolated benign prostate hyperplasia (BPH) so as to elucidate the motive for discrepancy of postvoiding residual urine.
  
  
  METHODS
  The study was conducted according to the standards of the local ethics committee. Patients gave informed consent. Disclosing the 3D XI display of the prostatic urethra and prostatic gland zones was a preliminary essential. The study included 113 men with a clinical diagnosis of BPH in whom transurethral resection of the prostate was planned. Patients aged from 52 to 75 years (mean 63). Other causes of infravesical obstructive uropathy and prostate neoplastic involvement were excluded. All patients were evaluated by three-dimensional Trans-Rectal Ultrasound using 3D XI methods. Patients were grouped according to the postvoiding residual urine volume into three groups, less and more than 100 mL and urine retention.
  
  
  RESULTS
  3D XI provided excellent resolution and diagnostic authority of prostate gland anatomy and for the appraisal of BPH morphology. The balance and type of nodular eruption proved responsible for the severity of symptoms aspires by extra-axial nodular effect upon the prostate urethra. The 3D XI analysis regarding the nodular stromal to glandular ratio compared to the histopathological results proved effectual in 98.3% of stromal-dominant, 100% in glandular-dominant and 93.3% in mixed type hyperplasia.
  
  
  CONCLUSIONS
  The severity of symptoms among men with BPH showed an association with the nodular credence, highlighted by 3D XI as a supportive tool in characterizing BPH.
