title: [Descriptive epidemiological study of the diagnosis of detrusor overactivity in urodynamic units in Spain].
abstract: OBJECTIVE
  To know the relative weight of the diagnosis of detrusor overactivity (DO) in the Urodynamic Units of Spain and relate the prevalence of the overactive bladder (OB) syndrome.
  
  
  METHODS
  An epidemiological, descriptive, retrospective, multicenter, national study conducted according to registered data in 47 Urodynamic Units covering the Spanish geographic area in the different areas of health distributed among the regional communities. These data inform about the health care received by 35% of the Spanish population. Urodynamic diagnoses and related variables, recorded during 2007 and 2008, were collected.
  
  
  RESULTS
  A mean of 346.45 (SD=304.03) and 349.72 (SD=296.49) urodynamics studies per care unit were performed in women during 2007 and 2008, respectively and 181.20 (SD=212.71) and 195.68 (SD=257.58) in men. The relative weight of the diagnosis of non-neurogenic DO in women per unit was 31.39% and 35.28%, in 2007 and 2008, and in men was 21.06% and 20.43%. The diagnostic capacity of DO was 19.28 new cases per 100,000 inhabitants/year. The diagnosis of non-neurogenic DO in the woman accounts for one third of all the urodynamic/year diagnoses and more than half of the diagnoses of DO. In men, DO accounts for 25% of the diagnoses, the most frequent one being that associated with benign prostatic hyperplasia, followed by that of neurogenic cause. Approximately half of the DO diagnoses in children correspond to non-neurogenic DO.
  
  
  CONCLUSIONS
  The differences between the capacity of diagnosis of DO (ratio per 100,000 inhabitants) is far from many of the estimations of the prevalence of OB (relationship %). The doubt may exist about whether part of this quota is secondary and not-idiopathic, given the large difference between the frequency of OB and the capacity of diagnosis of DO.
