Obstructive primary bladder neck disease: evaluation of the efficacy and safety of alpha1-blockers.
OBJECTIVE
The efficacy and safety of using alpha(1)-adrenergic blockers for treating primary bladder neck obstruction in young and middle-aged men was assessed as the first therapeutic step, before surgery, in a symptomatic non-neurogenic selected group of patients.


METHODS
From January 1995 to December 2001, primary bladder neck obstruction was diagnosed in 41 men whose average age was 43 years. All of them were evaluated by a complete clinical history, American Urological Association (AUA) symptom score index, physical examination, uroflowmetry, transabdominal ultrasound prostatic volume determination, ultrasound post-void residual determination, videourodynamics including pressure-flow analysis and upper urinary tract screening with renal ultrasound or an excretory urogram. A full daily dose of alpha(1)-adrenergic blockers (alfuzosin or tamsulosin) was administered for at least 6 months. Successful treatment was defined as improved symptoms, voiding diary, maximum flow rate and pressure-flow parameters. Patients who did not gain improvement of symptoms with pharmacological treatment were offered surgery.


RESULTS
Overall, pharmacological treatment was successful in 29/41 patients (70.7%) whereas bladder neck endoscopic incision was mandatory in 12/41 (29.3%).


CONCLUSIONS
alpha(1)-Blockers were effective and safe for treating young and middle-aged men with symptomatic bladder neck obstruction.
