Efficacy and safety of bladder neck incision in patients with benign prostatic hyperplasia.

Abstract

A prospective series of 104 patients underwent bladder neck incision (44 unilateral and 60 bilateral) for urinary obstruction caused by a small benign prostate enlargement. The preoperative mean peak flow value improved significantly from 11.4 ml/s to 16.2 ml/s. There were no significant differences in peak flow values between the unilateral and bilateral incision groups. Subjective results seemed to be similar but transurethral resection of the prostate was needed more often after unilateral incision than after bilateral incision. Postoperative complications were recorded only in the bilateral incision group. Altogether 62% of the patients reported changes in erection or ejaculation ability. Bladder neck incision seems to be an effective means of treating urinary obstruction but adverse effects on sexual function are common, which should be kept in mind when offering this treatment to sexually active men. It can be regarded as the treatment of choice for older men with infravesical obstruction caused by a small prostate enlargement.
