Down Regulation of Vascular Endothelial Growth Factor Is Associated With Decreased Inflammation After Intravesical OnabotulinumtoxinA Injections Combined With Hydrodistention for Patients With Interstitial Cystitis-Clinical Results and Immunohistochemistr

Increased VEGF was associated with bladder inflammation and smaller FBC in patients with IC/BPS and decreased after repeated onabotulinumtoxinA injections and hydrodistention, suggesting VEGF plays an important role in the pathogenesis of IC/BPS.
