Women who urinate very little but feel that their bladder is full may be caused by congenital urethral stenosis, urinary stones, nerve injury, bladder bulge and other reasons. 1. Congenital urethral stenosis: female patients with congenital developmental abnormalities leading to structural deformities of the urethra, urethral stenosis, urine discharge is blocked, so the above symptoms. 2. Urethral stones: when bladder stones are large in size, they block the urethral orifice of the bladder, resulting in urine not being able to be discharged and urinary retention; localized narrowing of the urethra caused by urethral stones will also restrict urination, thus giving rise to the above symptoms. 3. Nerve damage: stroke, multiple sclerosis, Guillain-Barré syndrome, spinal cord injury, lumbar disc herniation, diabetic peripheral neuropathy and other diseases lead to nerve dysfunction innervating the bladder forcing muscle, and there is kinetic urinary retention, so there are the above symptoms. 4. Bladder bulge: During delivery, the bladder bulges out to the anterior wall of the vagina and squeezes the neighboring urethra due to the damage of the supporting muscles between the bladder and the vagina caused by the oversized fetus and other factors, so the symptoms mentioned above will occur. There are also other reasons that can cause women to urinate very little but feel that the bladder is holding, such as bladder tumors, etc. It is recommended that patients seek medical attention to clarify the cause of the problem and treat it under the guidance of a doctor.
