Abstract
The effect of endoscopic bladder neck incision for functional bladder neck obstruction was assessed in 28 consecutive patients with a follow-up period of up to 50 months. The operation had excellent effect on the patients' symptoms consisting mainly of weak stream and/or recurrent urinary infections. Uroflowmetry at the postoperative follow-up study showed a statistically significant increase in as well maximum flow rate as mean flow rate. The bladder neck incision carried very few complications, and the average postoperative stay in hospital was 2.8 days. It is important to be aware of the condition functional bladder neck obstruction, and the diagnosis should be based upon uroflowmetry and voiding cystourethrography. In borderline cases with only slightly reduced urinary flow rate, additional pressure-flow studies should be applied to demonstrate infravesical obstruction.
