Loss of bladder control due to nerve damage affecting the bladder's ability to store or release urine.
Because neurogenic bladder is rated as either voiding dysfunction or urinary tract infection, the evidence that helps most is whatever documents your predominant symptoms and their severity.
For urine leakage or incontinence, records showing how frequently you change absorbent pads or use an appliance are directly relevant. A physician's note or your own statement describing daily pad use and how it affects your work and activities supports the criteria tied to change frequency.
For urinary frequency, a voiding diary or clinic notes recording your daytime voiding intervals and how many times you wake at night to void correspond directly to each rating level.
For obstructed voiding, uroflowmetry results showing peak flow rate, post-void residual measurements from ultrasound or catheterization, records of catheter use, and documentation of how often you need urethral dilation all map to specific criteria. Records of urinary tract infections — including hospitalization records, culture results, and prescriptions for suppressive antibiotic therapy — support the infection-based ratings. Your own statements describing how symptoms limit your ability to work, travel, or carry out daily activities add context to clinical findings.
