A pouch or sac that forms in the bladder wall and may trap urine or cause infection.
Because the rating depends on which dysfunction is predominant, your evidence should directly reflect your symptoms and their severity. For voiding dysfunction involving leakage or incontinence, medical records showing how often absorbent materials must be changed each day are key. For urinary frequency, records documenting your daytime voiding interval or how many times you wake at night to void support the specific rating levels. For obstructed voiding, urology records showing post-void residual measurements, uroflowmetry results, catheterization requirements, or how often stricture dilation is performed all speak to the criteria.
For urinary tract infections, records showing how often infections occur, whether any required hospitalization, whether drainage by stent or nephrostomy tube was needed, and the length of any suppressive antibiotic therapy directly tie to the rating levels. If kidney function has been affected, lab results showing glomerular filtration rate (GFR) measurements taken over at least three consecutive months are essential. Your own statements describing how bladder symptoms affect your work and daily activities also help document the full picture.
