A single\u2010center, prospective clinical trial was carried out aiming to show the effectiveness of narrow band imaging\u2010assisted transurethral electrocoagulation for ulcer\u2010type interstitial cystitis\/painful bladder syndrome.<\/jats:p><\/jats:sec>Methods<\/jats:title>A total of 23 patients (19 women and 4 men) diagnosed as having ulcer\u2010type interstitial cystitis\/painful bladder syndrome were included. All typical H<\/jats:styled-content>unner's lesions and suspected areas identified by narrow band imaging were electrocoagulated endoscopically after the biopsy of those lesions. Therapeutic efficacy was assessed prospectively by using visual analog scale score of pain, O<\/jats:styled-content>'L<\/jats:styled-content>eary\u2013S<\/jats:styled-content>ant's symptom index, O<\/jats:styled-content>'L<\/jats:styled-content>eary\u2013S<\/jats:styled-content>ant's problem index and overactive bladder symptom score.<\/jats:p><\/jats:sec>Results<\/jats:title>The mean follow\u2010up period was 22 months. All patients (100%) experienced a substantial improvement in pain. The average visual analog scale pain scores significantly decreased from 7.3 preoperatively to 1.2 1 month postoperatively. A total of 21 patients (91.3%) who reported improvement had at least a 50% reduction in bladder pain, and five reported complete resolution. Daytime frequency was significantly decreased postoperatively. O<\/jats:styled-content>'L<\/jats:styled-content>eary\u2013S<\/jats:styled-content>ant's symptom index, O<\/jats:styled-content>'L<\/jats:styled-content>eary\u2013S<\/jats:styled-content>ant's problem index and overactive bladder symptom score were significantly decreased postoperatively. However, during the follow\u2010up period, a total of six patients had recurrence, and repeat narrow band imaging\u2010assisted transurethral electrocoagulation of the recurrent lesions was carried out for five of the six patients, with good response in relieving bladder pain.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Our results showed that narrow band imaging\u2010assisted transurethral electrocoagulation could be a valuable therapeutic alternative in patients with ulcer\u2010type interstitial cystitis\/painful bladder syndrome, with good efficacy and reduction of recurrence
