Symptomatic nonobstructive voiding dysfunction in men involves distinct urodynamic abnormalities. Age influences the prevalence of detrusor instability and impaired contractility, impacting treatment strategies.

Area of Science:

  • Urology
  • Urodynamics
  • Men's Health

Background:

  • Lower urinary tract symptoms (LUTS) in men without bladder outlet obstruction (BOO) are common but poorly understood.
  • The underlying urodynamic mechanisms are not well characterized, leading to diagnostic challenges.

Purpose of the Study:

  • To define urodynamic abnormalities in symptomatic men without BOO.
  • To investigate the relationship between patient age and the type of voiding dysfunction.

Main Methods:

  • Video urodynamic studies were performed on symptomatic men without outlet obstruction.
  • Abnormalities included detrusor instability and impaired detrusor contractility.
  • Patients were classified into four groups based on urodynamic findings.

Main Results:

  • 40.9% had detrusor instability, 31.1% impaired contractility, 10.8% both, and 17.1% were normal.
  • Younger patients were more likely to have normal urodynamics.
  • Detrusor instability prevalence increased with age; bladder contractility did not correlate with age.

Conclusions:

  • Symptomatic nonobstructed men represent functionally distinct subgroups.
  • Treating based solely on symptoms may result in ineffective pharmacological therapy.
  • Accurate urodynamic assessment is crucial for appropriate management.
