Causes of increased residual urine in women are: 1. Dynamic factors, such as neurogenic bladder, abnormal complications of diabetic bladder function and other causes of weak bladder contraction, which can lead to incomplete urination and increased residual urine, and can even cause urinary retention, which can be treated with drugs that nourish the nerves and increase bladder contraction, and if necessary, consider intermittent catheterization or long-term indwelling cystostomy tubes. 2, Obstructive factors can be seen in adenoidal cystitis, bladder neck elevation due to bladder neck tumor, and urethral stricture caused by straddling injury, urethral meatus, paraurethral cyst, urethral mucosa prolapse partially blocking the external urethral opening, and bladder stones blocking the internal urethral opening in a piston-like manner, and gynecological tumors invading the urethra. For women with increased residual urine caused by obstructive factors, active treatment of the primary disease should be the key to its treatment.
