Children with chronic urinary tract infections, a neurologic lesion, an anatomic abnormality of lower urinary tract, voiding abnormality, and less than 1 year of oxybutynin treatment were excluded.

Urinary fibronectin levels in patients treated with intravesical bacillus Calmette-Guérin for superficial bladder cancer.

Intravesical bacillus Calmette-Guérin (BCG) has been shown to be an effective treatment for superficial transitional cell carcinoma (TCC) of the bladder, but the precise mechanism of action of BCG remains poorly understood. Fibronectin (FN), an important component of the extracellular matrix, has been found to play a role in BCG therapy. Some studies have shown that the soluble form of FN can compete efficiently with the matrix form of binding to the specific receptors on the bacteria and could consequently diminish the effect of BCG treatment.
