A 2-year study with 125 patients who suffered from symptoms suggestive of stenotic bladder neck with or without overlapping symptoms of 'abacterial prostatitis' is described. More than 200 balloon stretch tests were carried out in order to choose 125 patients for operation. With a knife electrode designed by one of us, two deep furrows were cut along the 5 o'clock and the 7 o'clock positions, which begin at the trigonum and continue through the entire bladder neck and the floor of the prostatic part of the urethra to the apex of the verumontanum.
