detrusor underactivity
bladder out flow obstruction
according to urodynamic, patients with weak urine stream were evaluated into 2 groups, either detrusor underactivity or bladder outflow obstruction From uroflowmetry, 5 variables including maximal flow rate (Qmax), average flow rate (Qave), voiding volume (VV), post void residual urine (PVR), and value of Qmax minus Qave (DeltaQ) were obtained.
