The data suggest that estradiol inhibits the initiation of CRC by regulating Nrf2-related pathways. Moreover, these imply the dual role of Nrf2 and NLRP3 inflammasome, including promotion of tumor progression upon tumor initiation.

Abbreviations & AcronymsObjective: To evaluate the efficacy and safety of augmentation ileocystoplasty with supratrigonal cystectomy for the treatment of refractory bladder pain syndrome/interstitial cystitis patients with Hunner's lesion. Methods: Of 45 patients who underwent augmentation ileocystoplasty with supratrigonal cystectomy between July 2006 and June 2012, 40 patients (33 women, 7 men) were included in the analysis. Primary outcome was the change in the O'Leary-Sant interstitial cystitis symptoms/problem index from baseline to 1, 3 and 6 months. Changes in pain, urgency, frequency, functional bladder capacity and maximal cystometric capacity were also assessed. Intraoperative and postoperative complications were evaluated. Results: Median preoperative symptom duration was 5.0 years (range 3.0-6.0 years). Pain decreased significantly after surgery (8.3 vs 1.3, P < 0.001). Functional bladder capacity and maximal cystometric capacity increased, whereas frequency, urgency and nocturia decreased significantly after surgery (all P < 0.001). At 6 months, significant improvements in the interstitial cystitis symptom index (17.8 vs 9.9, P < 0.001) and interstitial cystitis problem index (14.6 vs 6.5, P < 0.001) compared with baseline were noted. Seven patients developed vesicoureteral reflux and seven patients had acute pyelonephritis that resolved with antibiotic treatment. Five patients required clean intermittent self-catheterization. None of the preoperative factors were significant predictors of treatment failure. Conclusions: Augmentation ileocystoplasty with supratrigonal cystecomy decreased pain and frequency, and increased bladder capacity significantly. There were no severe complications related to surgery during follow up. Augmentation ileocystoplasty with supratrigonal cystectomy is therefore an appropriate final treatment strategy for refractory bladder pain syndrome/interstitial cystitis patients with Hunner's lesion.

TUI for failed MUS demonstrated a low cure rate but high patient satisfaction, and the procedure was minimally invasive with no significant complications.
