title: [Cholinergic and adrenergic innervation of the bladder obstructed by urethral stenosis in the rat].
abstract: In the obstructed bladder by urethral stenosis the morphometry studies show a decrease of the cholinergic and adrenergic intrinsic innervation in a different way according the tissue layer and the experimental delay. Adrenergic nerves are more affected than cholinergic ones but they recover more quickly. In the adventitia and the sub-mucosa first affected by the high pressures inside the bladder the density of the autonomous nerves decreases from the first week. The perivascular and muscular nervous fibers are less sensitive and the similar shape of their innervation histogram gives evidence of a tight bond between their adrenergic network. Beside their motor participation the adrenergic terminal fibers may play a role in the cellular trophicity of the muscle.
