Detrusor contractility in hyperreflexic bladders (from intracerebral neuropathies) versus unstable and stable unobstructed ones.

Three male patient groups of 20 subjects each have been assessed urodynamically by pressure flow study, namely, patients with detrusor hyperreflexia (DH) due to intracerebral neuropathies were compared with subjects bearing a condition of idiopathic detrusor instability, as well as with a control group of males showing normal urodynamic findings. Detrusor contractility proved greater in the unstable patients, but did not differ significantly between those with DH and the controls. Such results may suggest that intracerebral neuropathies leading to DH have no influence on, whilst the factors responsible for detrusor instability are strongly related to, the degree of activation of bladder muscle mechanical capability.
