title: Impact of the endorectal ultrasound probe on uroflow parameters in males.
abstract: OBJECTIVE
  The aim of this study was to test the null hypothesis that the presence in the rectum of an endorectal ultrasound probe during transrectal voiding ultrasonography (TRVUS) would have no significant effect on uroflowmetry parameters.
  
  
  METHODS
  We studied 43 randomly selected men undergoing TRVUS of the prostate for non-neurogenic lower urinary tract symptoms. Uroflowmetry was performed immediately before and during the TRVUS. Results were compared with a paired Student's t test; the null hypothesis was confirmed by p values >0.05.
  
  
  RESULTS
  Forty patients were able to void with the endorectal probe inserted, and 95% described this micturition as representative of their usual voiding behavior. No significant statistical difference was found between uroflowmetry parameters before and during TRVUS, confirming our null hypothesis.
  
  
  CONCLUSIONS
  Our data suggest that uroflowmetry in combination with TRVUS can be a reliable tool for evaluating disorders of micturition in males, at least in selected cases.
