My colleagues & I first reported on a group of patients with vulvodynia who were noted to have IC as diagnosed by the PST1,3. This initial data collection was part of study of a larger group of patients with pelvic pain who were screened for urinary symptoms and tested for IC using the PST. Last month, we reported solely a series of patients presenting with GV who were tested for IC using the PST3. In this most recent report, 102 / 122 (84%) of patients with GV were found to have a positive PST. These data suggest that many patients with vulvodynia may have pain of bladder origin.
