Figure 4 Urodynamic patterns of male patients older than 45 years neurologically intact with symptoms of lower urinary tract/bladder outlet obstruction[17]. A: Pattern A [equivocal or mild bladder outlet obstruction (BOO) with sphincter synergia with or without idiopathic detrusor overactivity]; B: Pattern B (equivocal or mild BOO with idiopathic sphincter overactivity); C: Pattern C (classic BOO with sphincter synergia); D: Pattern D (classic BOO with idiopathic sphincter overactivity); E: Pattern E (BOO with only detrusor low compliance); F: Pattern F (BOO with both detrusor underactivity and low compliance); G: Pattern G (equivocal BOO with detrusor underactivity); H: Urodynamic study of a patient with pattern F; I: The same patient with pattern F as in H after 4 wk urinary draining, whose detrusor contraction recovered and urodynamic study pattern was transformed into pattern E.
