A botulinum toxin A (BoNT-A) intravesical injection can steely dan gaucho t-shirt improve the symptoms of interstitial cystitis/bladder pain syndrome (IC/BPS).Patients with IC/BPS have different clinical characteristics, urodynamic features, and cystoscopic findings.This study assessed the treatment outcomes of a BoNT-A intravesical injection and aimed to identify the predictive factors of a satisfactory outcome.This retrospective study included IC/BPS patients treated with 100 U BoNT-A.The treatment outcomes were assessed by global response assessment (GRA) at 6 months.
We classified patients according to different clinical, urodynamic, and cystoscopic characteristics and evaluated the treatment outcomes and predictive factors.A total of 238 patients were included.Among these patients, 113 (47.5%) had a satisfactory outcome (GRA ≥ 2) and 125 (52.5%) had an unsatisfactory outcome.
Improvements in the IC symptom score, IC problem score, O’Leary−Sant symptom score, and visual analog scale score for pain were significantly greater in patients with a satisfactory outcome than in patients with an unsatisfactory outcome (all p = 0.000).The IC disease duration and maximal bladder capacity (MBC) were significantly different between patients with bob the boxcutter and without a satisfactory outcome.Multivariate analysis revealed that only the MBC was a predictor for a satisfactory outcome.Patients with a MBC of ≥760 mL and glomerulations of 0/1 (58.
7%) or glomerulations of 2/3 (75.0%) frequently had a satisfactory outcome.We found that BoNT-A intravesical injection can effectively improve symptoms among patients with IC/BPS, with a remarkable reduction in bladder pain.A MBC of ≥760 mL is a predictive factor for a satisfactory treatment outcome.
