In this randomized controlled trial, we will evaluate if bipolar enucleation of the prostate (BEEP) is associated with better urinary voiding outcome than transurethral resection (TURP) in men with enlarged prostate referred to surgery. In addition we will investigate the association between symptom relief and the amount of removed tissue and if patients experience differ between the two methods. Finally, we will assess cost-effectiveness of BEEP compared to TURP. The main outcome for comparison of the two surgical methods is International Prostate Symptom Score (IPSS) assessed at 12-month follow-up. The primary outcome to assess patient experience is measured with the questionnaire Nordic Patients Experience Questionnaire (NORPEQ). Cost-effectiveness will be measured with incremental cost-effectiveness ratio (ICER).
