The treatment of female bladder neck dysfunction.

During the period 1981-88, 38 women who eventually had the diagnosis of bladder neck obstruction established, were treated by bladder neck incision. Their age range was 28-85 years. The preoperative investigations included a full urodynamic examination and urethro-cystoscopy. The gynecologic examination was normal. The most constant finding was an elevated, rigid bladder neck seen by endoscopy. The treatment included a bladder neck incision either at 4 or at 8 o'clock. The results four weeks postoperatively were good, the symptoms had disappeared or the patients were improved in most cases, and the flow curves were normalized. Mean observation time was 55 months. After a longer period of time the symptoms in some cases returned, and then the incision was repeated. After the final control, we found 76% of the patients symptomatically improved.
