Urinary nitrites

Urinary nitrites are higher in patients with enuresis (1) indicating a connection between nitric oxide (NO) regulation and enuresis ("over-active bladder"). "NO plays an important role in the micturition process and disorders [IC, cystitits, enuresis] of the lower urinary tract."(2) Some IC patients show significant improvement with decreasing bladder NO.(3)
Nitric oxide (NO) has been shown to be significantly higher in the prostatic urethra of NIH-IIIa patients, but not in NIH-IIIb patients.(4)
