After stroke or spinal cord injury, patients often develop bladder dysfunction, but in clinical work, physical dysfunction is often valued and treated, and systematic bladder assessment and treatment is rare, becoming a forgotten corner in the clinic. Patients often develop urinary infections and renal dysfunction because of lack of systematic treatment, which is one of the most common factors of death. Therefore an aggressive assessment and appropriate management based on the assessment results is crucial for patients with bladder dysfunction. The bladder urometry assessment system, a new instrument used for assessment of functional assessment and training, can effectively assess the bladder volume-pressure relationship, can meet more than 90% of the needs of neurogenic bladder assessment, can provide accurate recording and analysis, is easy to operate, safe, and can be used for assessment of functional monitoring and training. At present, our department is applying this device to actively carry out the assessment of flat bladder function in spinal cord injury and stroke patients and treating more than 10 patients, all of whom have achieved good results. The scope of application of this equipment, spinal cord injury, stroke, traumatic brain injury and other causes of bladder dysfunction assessment, treatment of spastic bladder.
