[Modification of the tissue thickness of the bladder in obstruction by urethral stenosis].
In experimental obstructed bladder by urethral stenosis, the trigone and the detrusor walls thicken in a very important but different way. The thickened mucosa and submucosa of the total bladder show oedema and hypertrophy of the connective fibro-elastic tissue. Related to the different axis of the pressure inside the bladder and the specific muscular architecture of both regions, the adventitial and muscular layers show no modification in the trigone but they become thinner in the detrusor.
