It is a condition in which the patient has an obvious urge to urinate and the bladder area is suffocated, that is, the small stomach is suffocated, but cannot urinate on its own, sometimes manifested as urine dribbling, that is, dripping from the urethra. The causes of urinary retention in elderly women may be: i. caused by obstruction of the lower urinary tract, such as urethral stricture, contracture of the bladder neck orifice, and elevation of the trailing edge of the bladder neck, which means that there is an obstructive lesion at the bladder outlet. Second, poor bladder contraction, often due to complications such as long-term diabetes, cerebrovascular disease accidents, or long-term bed rest, generalized muscle atrophy, can cause neurogenic bladder. Third, trauma to the cerebral spinal cord, so that the urination center is affected.
