The causes of incomplete urination in women: 1, bladder prolapse. As women age, the pelvic floor muscles will relax and the bladder will prolapse from the front wall of the vagina, and the angle between the bladder and the urethra will become larger, so some urine will remain in the bladder when urinating and cannot be drained. On physical examination, the anterior vaginal wall protrudes from the surface of the vagina with abdominal pressure and is soft to the touch. This is a functional change, and usually the effect of oral medication is not satisfactory. If the sense of incomplete urination is obvious, if the residual urine is more than 50 ml as measured by ultrasound, or if there are repeated secondary infections, surgical treatment can be performed to restore the function of urination by pelvic floor reconstruction surgery. 2. Hypoactive bladder function. It can be seen in various central nervous system lesions or peripheral nervous system lesions, which lead to the decrease of bladder contraction function, resulting in the weakening of bladder contraction force, part of the urine is excreted and part of the urine is retained in the bladder. Patients often feel a sense of incomplete urination, and when they use ultrasound to measure residual urine, the amount of residual urine is always greater than 50 ml or more, and they have sequelae of cerebral hemorrhage or cerebral infarction or have long-term chronic neurological functional diseases, such as type 2 diabetic peripheral neuropathy. The diagnosis requires urodynamic testing, and if it is confirmed that the contractility of the bladder’s forced urinary muscles is reduced, the treatment effect is relatively poor.3. Chronic infections of the urinary system, such as long-term chronic infections leading to the loss of the aminoglycoside layer in the bladder, which is often felt by patients as frequent urination and accompanied by a sense of incomplete urination. If you use ultrasound to detect residual urine, the residual urine is mostly less than 50ml, but the urine culture may have bacterial infection, and anti-infection treatment has a certain effect.
