What are the differences between stress incontinence and fullness incontinence?

Stress urinary incontinence is caused by a decrease in the contractile force of the urethral sphincter and its ability to close the urethra. When the bladder shows excessive pressure, urine will flow out of the body without conscious control. Filling urinary incontinence is caused by a decrease in the contractile force of the bladder, a large amount of urine in the bladder, and the urethral sphincter's ability to close the urethra is normal. When there is a large amount of urine in the bladder, its pressure exceeds the urethral sphincter's force to close the urethra, and it will also show that urine flows out of the body on its own. There are also differences between the two auxiliary tests. Stress urinary incontinence checks the residual urine volume of the bladder, which is often absent. And filling urinary incontinence checks the residual urine volume of the bladder. Even if the patient has passed urine, there is still a large amount of urine in the bladder, and the residual urine volume is very large.
