1. Scientifically formulate the catheterization program to reduce the incidence of urinary tract infection.

In intermittent catheterization, bladder scanner is used to measure the urine volume of the bladder to avoid early or late catheterization, reduce the number of intubation and reduce the risk of infection.

2. To provide basis for the timing of prostate surgery.

The urethral stricture caused by prostate disease leads to dysuria and other symptoms. The urine volume before and after urination is measured to evaluate the status of urination function, so as to provide basis for determining the opportunity of surgical treatment and avoid the pain of using catheterization for diagnosis of patients.

3. Provide basis for evaluating bladder function.

There are pathological changes in both high compliance and low compliance bladders. The measurement of bladder urine volume can provide a basis for clinical evaluation of bladder compliance.

4. Provide the basis for choosing the opportunity of bladder retraining.

For patients who have problems with bladder micturition function, they need to be trained in the process from artificial catheterization to self micturition: use bladder scanner to monitor urine volume and make training plan. 

For example: neurogenic bladder retraining, bladder retraining for stroke patients, and bladder retraining after cervical cancer surgery.

5. Bladder monitoring.

monitoring of chronic urinary retention, monitoring of urine output in extreme urine retention, monitoring of renal function and metabolism in critically ill patients.

6. Monitor the catheterization process.

The bladder scanner can display the real-time changes of bladder shape and urine volume, and make catheterization from blind insertion to visualization.

7. Measurement of bladder urine volume and residual urine volume, as auxiliary tools of urodynamic and uroflow rate test, is also an important tool of evidence-based medicine and evidence-based nursing.
