If the bladder has decreased bladder storage function due to various reasons, the following methods can be used to observe whether the bladder storage function can be improved. 1. Intermittent clamping of the urinary catheter to train the bladder is required, and after the catheter is placed, the urinary catheter needs to be intermittently clamped to make the bladder in a full state. When the patient feels a strong urge to urinate, record the time and open the urinary catheter to record the amount of urination. After continuous recording, intermittently extend the time of clamping the urinary catheter to improve the urinary storage function of the bladder.2. Oral medication to reduce the sensitivity of the bladder and increase the urinary storage function of the bladder. The drug can be chosen from tolterodine tartrate tablets, 2mg, taken orally twice daily. Or Solifenacin succinate tablets, 5mg, orally once a day. Observe whether the function of bladder urine storage is improved by medication.3. Surgery. Bladder enlargement or bowel substitution bladder surgery, etc., can be used to enlarge the capacity of the bladder and increase the volume of the bladder. Surgery is often recommended for patients with bladder contracture due to various irreversible damages and a bladder volume of less than 50 ml.
