  1. No. or n indicates the number of cases.
  2. TUR indicates transurethral resection of bladder tumour.
  3. *The tumor staging is based on the current World Health Organization (WHO) classification/AJCC manual 7th edition.
  4. @ 9 cases of pTa (based on the intradiverticular pathological staging), 2 out of 9 these cases were pT1 in their extradiverticular lesions. Survival statistics was based on the higher staging regardless of the tumor locations.
