Comparison of the Efficacy Between Transurethral Coagulation and Transurethral Resection of Hunner Lesion in Interstitial Cystitis/Bladder Pain Syndrome Patients: A Prospective Randomized Controlled Trial[Formula presented]

In interstitial cystitis/bladder pain syndrome patients with Hunner lesion, either transurethral resection (TUR) or transurethral coagulation (TUC) of Hunner lesion is a definite treatment in terms of symptom improvement and quality of life. However, TUR of Hunner lesion is not superior in recurrence-free time to TUC, but may have a higher chance to develop bladder injury. Therefore, surgeons prefer a surgical method that they are familiar with, but less experienced surgeons may use TUC to reduce surgical complications.
