title: Evaluation of bladder contractility in men undergoing transurethral resection of the prostate.
abstract: OBJECTIVE
  We analyzed preoperative and postoperative urodynamic parameters in 26 patients who underwent transurethral prostatic resection with the aid of a computer program. The parameters URA, W and Wmax were evaluated: URA affords a monitoring of the removal of obstruction, while Wmax and W function monitor changes in detrusor contractility, which appear significant after prostatic resection in obstructed patients.
  
  
  RESULTS
  Many patients had a fading contraction, that is detrusor contractility decreased during micturition: in most of them the removal of obstruction restored this pattern to normal.
  
  
  CONCLUSIONS
  Evaluation of these parameters is recommended for preoperative assessment and postoperative follow-up.
