Urinary incontinence and enuresis is what causes it?

1, causes Classification

1. Urinary incontinence, bladder stones, tuberculosis, cancer and other diseases, so that excessive detrusor contraction, urethral sphincter relaxation, or paralysis, so that the bladder to lose urine storage function, there is urine or discharge, also known as self-bladder.

2. Urinary incontinence, lower urinary tract obstruction, chronic urinary retention in patients with overactive bladder inflated, the bladder pressure is increased, so that the urine was forced to overflow, said pseudo-incontinence, also known as enuresis.

2, Mechanism

Have a certain tension normal urethral sphincter, detrusor in a state of relaxation, so that the urine stored in the bladder, the voiding reflex by a series of activities to detrusor contraction, sphincter relaxation, urine. In case of persistent urinary muscle spasm, or excessive sphincter relaxation, may allow accumulation of urine within the bladder can not be automatically out, that is, urinary incontinence, urinary incontinence, said authenticity. If there is lower urinary tract obstruction, or detrusor weakness, urinary retention in the bladder, so that over-filling of the bladder stagnation pressure was gradually increased, urine may at any time overflow, resulting in "filling urinary incontinence," namely, pseudo-incontinence, but also called enuresis.
