Our study was divided into two arms; the primary arm had no prior diagnosis of bladder malignancy (<jats:italic>N<\/jats:italic>\u00a0=\u200941), whereas secondary re\u2010resection arm had (<jats:italic>N<\/jats:italic>\u00a0=\u200957). Three patients with non\u2010urothelial bladder cancer were excluded. Patients were followed up for 24\u2009months. Data were collected on biopsy quality, histopathological characteristics and recurrence. The end points of the study were recurrence rate at 24\u2009months in both arms and detection of CIS in patients who undergo TURBT or biopsy after initial white light study in the secondary, re\u2010resection arm.
