Abstract

PURPOSE:

We reviewed the urodynamic findings and treatment outcomes of a large series of men with primary bladder neck obstruction.

MATERIALS AND 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.
