title: Primary bladder neck obstruction: urodynamic findings and treatment results in 36 men.
abstract: OBJECTIVE
  We reviewed the urodynamic findings and treatment outcomes of a large series of men with primary bladder neck obstruction.
  
  
  METHODS
  A retrospective review was done of the presenting symptoms and urodynamic findings of 36 men with primary bladder neck obstruction. Outcomes after treatment with alpha-blockers, transurethral incision of the bladder neck and prostate, or no long-term therapy were determined by chart review and patient survey in the majority of cases.
  
  
  RESULTS
  Mean age of the men was 41 years. Patients had significant lower urinary tract symptoms, decreased peak urinary flow rates, elevated post-void residual, markedly elevated peak voiding pressures and poor funneling of the bladder neck during voiding. Although most patients initially chose alpha-blocker therapy, only 30% of those beginning alpha-blockers continued them long term, usually due to inadequate symptomatic improvement. A total of 18 men underwent transurethral incision, which resulted in significant improvements in symptom scores, peak urinary flow rates, post-void residual and peak voiding pressures. Patients reported a mean 87% overall improvement in symptoms after transurethral incision.
  
  
  CONCLUSIONS
  Video urodynamics facilitate diagnosis of primary bladder neck obstruction. Transurethral incision is the most effective therapy for primary bladder neck obstruction.
