Typically, diminished urethral muscle contraction may be caused by dysfunction of the uroepithelium, subepithelial tissue, and/or dysfunction of the urethral muscles. Symptoms such as urinary urgency, dysuria, and urinary frequency are common with decreased contractility of the forced urethral muscles. 1. Urgency of urination: Urgency of urination is the most common symptom in more than 50% of patients with weakened forced urethral muscle contractility. Weakened detrusor contractility can cause an increase in residual urine as well as a decrease in functional bladder capacity, and is often secondary to urinary tract infections, causing changes in urinary flora, which can lead to worsening of urinary urgency symptoms. 2. Insufficient urination, frequent urination: there is still a feeling of urine after urination. It also causes a feeling of bloating in the abdomen, because of the weak contraction of the forced urinary muscles, the urine will be stored in the bladder, so the patient always feels that there is urine in the bladder can not be drained or each time you can only use abdominal pressure to urinate, in order to discharge a little bit of urine in the bladder, the patient will go to the toilet again and again, but each time the amount of urine is not much. 3. Other: If patients with prolonged forced urinary muscle weakness have fluid in the kidneys or large amount of urinary retention, it will lead to urinary tract infection, and there will also be pain in the lower abdomen, pain in urination, weakness in urination and other symptoms. Weakness of the forced urethral muscle contraction will also have other clinical symptoms, if there is obvious discomfort, it is recommended to immediately go to a professional hospital, under the guidance of the doctor for examination and treatment.
