Bladder cancer (BC) is a rather common disease. The incidence of bladder cancer in the population is gradually increasing[3,7] In non-invasive bladder carcinoma (NICM), transurethral resection of bladder tumour (TUR) is the cornerstone of treatment. Successful treatment of these tumours depends on adequate initial resection and an accurate histological diagnosis. After TUR alone, around 50 70% of patients develop recurrence. Reasons for this high rate of recurrence of NICMP have been cited for incomplete resection during the initial TUR, aggressive tumour biology, and implantation of tumour cells[6,8,9].
