Objective And Methods:
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.
Conclusion:
Evaluation of these parameters is recommended for preoperative assessment and postoperative follow-up.
