Abstract
Purpose: Differences in the severity of subjective symptoms have been noted depending on whether a Hunner lesion is present in women with interstitial cystitis/bladder pain syndrome (IC/BPS). In this study, we aimed to identify differences in objective urodynamic parameters in women with IC/BPS according to the presence of a Hunner lesion. Methods: This cross-sectional study included a total of 55 patients with IC/BPS. IC/BPS and the presence of a Hunner lesion on cystoscopy were diagnosed according to American Urological Association guidelines. The patients were categorized into a Hunner IC/BPS group and a non-Hunner IC/BPS group according to the presence of a Hunner lesion on cystoscopy. At the initial visit, a medical history was taken from all patients with IC/BPS, and they underwent symptom assessment using a 3-day voiding diary and laboratory tests. A urodynamic study was then performed before any treatment was performed. Baseline characteristics and urodynamic parameters were compared between the 2 groups. Results: Of the 55 patients, 23 (41.8%) had a Hunner lesion on cystoscopy. As documented in the voiding diaries, the Hunner IC/BPS group had more frequent voids and a smaller maximal voided volume (P = 0.045, P < 0.001, respectively). Regarding urodynamic parameters, the mean volume at the first desire to void, normal desire to void, strong desire to void (SDV), and maximum cystometric bladder capacity (MBC) was significantly lower in the Hunner IC/BPS group (P = 0.001, P = 0.004, P < 0.001, and P < 0.001, respectively). On receiver operating characteristic curve analysis, patients with an SDV <= 210 mL (area under the curve [AUC] = 0.838, P < 0.001) and an MBC <= 234 mL (AUC = 0.857, P < 0.001) were likely to be in the Hunner IC/BPS group. Conclusions: The differences in patients' subjective symptoms between the Hunner IC/BPS and non-Hunner IC/BPS groups were confirmed to correspond to differences in objective urodynamic parameters.
