Our aim was to review the results of unilateral transurethral incision (TUI) of the bladder neck for the treatment of primary bladder neck obstruction. A total of 35 patients with the mean age of 40.31 years were included in the study. The international prostate symptom score (I-PSS), quality of life (QoL) score, uroflowmetry and sperm count were determined. The mean preoperative I-PSS was 32.1 points, peak urine flow rate was 7.8 cc/s and sperm count was 59.2 million/cc. There was a 28% reduction of I-PSS at 3 months, 38% at 6 months and 55% at 1 year. The urine peak flow rate increased by 54% at 3 months, 83% at 6 months and 95% at 1 year. The reduction in the sperm count was 63% at 6 months and 69% at 1 year. The QoL score improved significantly after 1 year compared with the preoperative period. Unilateral TUI of the bladder neck is an effective treatment for primary bladder neck obstruction. However, the postoperative sperm count is significantly reduced at 6–12 months (18–21 million/cc) but is probably sufficient for adequate fertility.
