Late results after transurethral bladder neck incision.

Objectives: To assess the long-term results of transurethral bladder neck incision with regard to symptoms and urodynamic findings.
Patients and Methods: Between September 1986 and September 1992, 73 patients were studied. The patients were examined preoperatively and 2, 6, 12, 18 and 64 months postoperatively. Evaluation of subjective symptoms according to Madsen's and Iversen's symptom score and uroflowmetry were performed.
Results: At the 64-month follow-up, 1 patient had died and 11 patients were lost to follow-up. A mean symptomatic improvement was documented in 74% of the cases (range: 60-93%) for the whole period of the follow-up. Subjective assessment showed a statistically significant reduction of the voiding complaints. Postoperative measurements of peak urinary flow rate (PFR) were above 15 ml/s in 78% of the patients. We did not find any statistically significant decrease in residual volume within the group of patients with a preoperative residual urine volume below 50 ml. Such a difference was found in patients which presented with complete urinary retention or residual volume of 150-250 ml.
Conclusions: Urodynamic and subjective improvement remained durable up to 64 months after bladder neck incision.
