When not urinating, the urethral sphincter contracts to close the urethra, the bladder forcing muscle relaxes and the bladder stores urine; when urinating, the urethral sphincter relaxes and opens the gate, the bladder forcing muscle contracts, squeezing the bladder and emptying the urine. Urination abnormalities explained in one sentence in layman’s terms 1. enhanced bladder sensation very little urine in the bladder and very early desire to urinate. 2.Weak bladder sensation has a lot of urine in the bladder and no urge to urinate occurs. 3.Lack of bladder sensation never want to urinate no matter how much urine is in the bladder. 4. overactive/unstable forced urinary muscles without conscious command and involuntary contraction of the forced urinary muscles of the bladder. 5, involuntary contraction of the bladder forcing muscle when the overactive forceps urinary incontinence does not want to urinate leads to leakage of urine. 6, Incomplete urethral closure mechanism bladder forced urinary muscle is not contracted is also occurrence of leakage. 7, low activity of the detrusor muscle bladder detrusor muscle contraction is weakened, resulting in prolonged urination and/or incomplete emptying of urine. 8, No contraction of the force of the forceps urinaryis muscle does not contract when you want to urinate. 9 .Bladder outlet obstruction The passage for urination is blocked. 10 . Synergistic dysfunction of the forced urinary sphincter muscle When urinating, the forced urinary muscle contracts at the same time as the sphincter muscle around the urethra also contracts, closing the urethra partially or even completely. 11, stress incontinence in coughing, sneezing or other actions that increase abdominal pressure, the urethral gate does not close completely and leaks urine. 12. True urinary incontinence, no matter what you do, even when you are sleeping, the urethral gate does not close completely and you leak urine.
