Introduction: Detrusor underactivity (DUA) is defined by the IUGA /ICS terminology report, 2010as detrusor contraction of reduced strength and/or duration,resulting in prolonged bladder emptying and/or a failure to achievecomplete bladder emptying within a normal time span. The definitiondoes not establish a cut off value for detrusor pressure during theflow.
Objective: DUA is difficult to clinicallydifferentiate from other bladder dysfunctions. Excluding women withsignificant pelvic organ prolapse, bladder outlet obstruction is anuncommon condition, consequently data are lacking. The aim of thisstudy was to analyse the voiding volume and max flow in theurodynamic testing in different age groups.
Methods: Inthis retrospective study we sorted a database from 1998 to 2017 withrespect to gender and urodynamic testing. Nearly 1500 female patientswith a pressure flow study were collected. As inclusion criteria wedefined flow under the normal range (age dependent: <45 y = 18ml/s, 46-65 y = 15 ml/s, >65 = 10 ml/s) or residual urin. Weexcluded all patients with a mechanical obstruction oranticholinergic medication, voiding volume under 50cc and presence ofneurological diseases. Finally, patients were separated in 3different age groups (young = < 45y, middle age = 46-65, elderly => 65).
Results: We evaluated the data of 177 femalepatients. 57 women reached the criteria of detrusor underactivity.However, after application of exclusion criteria, 27 remainedeligible for the study analysis. DUA were mainly present in the groupof elderly women (13). Voiding volume and max flow decreased withage, residual urin increased (p > 0,100). Concerning the pdet@flowmax we found a trend comparing young with middle-aged (F(2;24) =3,397 p = 0,062) and young with elderly patients (p =0,075).
Conclusions: Our data give support to the fact thatthe frequency of DUA increases over time, and further studies areneeded to clarify the real prevalence of DUA and its clincalconsequences in different group ages. In our opinion, thisobservation has potential consequences in the therapy decisionprocess in patients with symtpoms of urinaryincontinence.
