What is a bladder diverticulum?

Bladder diverticulum is caused by congenital dysplasia of bladder muscle layer, high pressure in bladder, inflammation stimulation, etc.

1. Congenital

dysplasia of bladder muscle layer can lead to bladder wall muscle dysfunction, so that bladder can not be completely contracted when emptying, resulting in residual urine retention, forming bladder diverticulum.

2. High pressure in bladder

Pregnancy, childbirth and other factors will increase bladder pressure, resulting in bladder neck tissue relaxation, bladder mucosa bulging out of the pocket, called bladder diverticulum.

3. Inflammation stimulation of

urethra and bladder neck can also lead to bladder neck tissue relaxation, and then cause bladder diverticulum.
