Neurogenic Bladder: Epidemiology, Diagnosis, and Management

Area of Science:

• Neurology
• Urology
• Nephrology

Background:

• Lower urinary tract dysfunction (LUTD) is a frequent complication of neurological disorders, significantly diminishing patients' quality of life.
• The specific neurological lesion and its characteristics dictate the pattern of urinary dysfunction.
• Morbidity, including upper urinary tract damage and renal failure, varies based on the neurological condition, with slowly progressive disorders posing less risk than spinal cord injury or spina bifida.

Purpose of the Study:

• To review the evaluation and management strategies for lower urinary tract dysfunction in patients with neurological diseases.
• To highlight the importance of an individualized, patient-tailored approach to managing these complex conditions.

Main Methods:

• Preliminary evaluation involves patient history and bladder diaries.
• Diagnostic tools may include uroflowmetry, post-void residual measurement, renal ultrasound, urodynamics, neurophysiology, and urethrocystoscopy.
• Management strategies encompass intermittent catheterization, antimuscarinic medications, onabotulinumtoxinA injections, neuromodulation, and reconstructive urological surgery.

Main Results:

• Incomplete bladder emptying is typically managed with intermittent catheterization.
• Storage dysfunction is often treated with antimuscarinic medications.
• OnabotulinumtoxinA injections have significantly advanced the treatment of neurogenic detrusor overactivity.
• Neuromodulation shows promise for both storage and voiding dysfunctions.

Conclusions:

• An individualized, patient-tailored approach is essential for managing lower urinary tract dysfunction in patients with neurological conditions.
• Diverse therapeutic options exist, ranging from conservative measures to surgical interventions.
• Effective management can mitigate risks of upper urinary tract damage and preserve renal function.
