Transurethral incision of the prostate: a preoperative and postoperative analysis of symptoms and urodynamic findings.

The efficacy of transurethral incision of the prostate was evaluated prospectively in 26 men with urodynamic evidence of outlet obstruction secondary to small prostate glands (estimated size less than 30 gm). All men completed preoperative and postoperative symptom questionnaires and extensive urodynamic testing with a median postoperative followup of 16.25 months. There was a significant improvement in subjective symptom analysis and objective urodynamic parameters (peak and mean uroflow rates, maximal detrusor pressure at peak flow, volume at first urge and post-void residual volume) as a result of transurethral incision of the prostate with minimal postoperative morbidity. Antegrade ejaculation was preserved in 55% of the men with normal preoperative ejaculation. Based on subjective and objective criteria, transurethral incision of the prostate is an effective treatment option for selected men with outlet obstruction.
