RANDOMIZED CLINICAL-TRIAL COMPARING BALLOON DILATATION TO TRANSURETHRAL RESECTION OF PROSTATE FOR BENIGN PROSTATIC HYPERPLASIA

To evaluate the effectiveness and clinical outcome of patients treated by balloon dilatation of the prostate (BDP) compared with transurethr al resection of the prostate (TURP) we performed a prospective, random ized clinical trial. Fifty-one men were randomized to either BDP or TU RP. Both groups demonstrated a significant decrease in symptom score f rom preoperative levels (TURP 13.6 to 6.0 [p < 0.05]; BDP 14.1 to 8.1 [p < 0.01] at 1 year). The TURP group improved peak urinary flows; whi le, after initial improvement, the balloon group returned to pre-proce dure levels. At twelve months 14 of 19 BDP patients (74%) and 14 of 18 TURP patients (78%) considered themselves improved. BDP results in sy mptomatic improvement; however, the effect may not persist. Objective improvement after BDP does not always occur. The morbidity of BDP is l ow and compares favorably to that of TURP. Thus BDP does not appear to be as effective as TURP and may offer only temporary relief of sympto ms.
