[Balloon dilatation vs. prostatic transurethral resection in stages I-II prostatic adenoma].

Thirty consecutive patients with benign prostatic hypertrophy St. I-II (adenom weight < 25g) were treated either by balloon dilatation (Group I) or transurethral resection (group II). Peak flow, residual urine and voided urine did not improve after balloon dilatation in a follow-up of 9 months. In contrast peak flow enhanced after TUR-P from 10.4 ml/sec. to 21.9 ml/sec. Residual urine reduced from 65 ml to 30. In group I obstructive symptom score (6.1 > 4.5) and irritative symptom score (5.5 > 3.6) decreased after 9 months, TUR-P resulted in a greater reduction of obstructive score (7.4 > 1.6) and irritative score (6.0 > 2.4). This study with selected patients does not support indications for balloon dilatation.
