How to diagnose neurogenic detrusor overactivity (NDO)
Early diagnosis and treatment of NDO is essential to prevent irreversible changes within the urinary tract.6
The diagnosis of NDO should include a detailed history, general and neurological physical examination and urinalysis.6–9
Assessment of the patient’s risk factors and quality of life is also required.6 For initial management, basic diagnostic tests should be used to exclude an underlying disease.8
For specialised management, more elaborate assessment is generally required, including imaging, endoscopy and urodynamics.8
Urodynamics assess filling and storage in the urinary tract and can be used for diagnosis and to direct targeted treatments.6
In patients with spinal cord injury, there is a high correlation between functional level of injury and urodynamic abnormalities. Unmanaged high detrusor pressure is a trigger for upper urinary tract injuries leading to deterioration of the upper urinary tract function and kidney failure.10,11
In patients with multiple sclerosis, urodynamic assessment should be repeated at regular intervals to optimise clinical management, reduce complications, and better enable patients to manage their condition.12
