title: [T1 bladder cancer: role of documentation for bladder tumor findings and targeted second resection].
abstract: BACKGROUND
  For control resection of T1 bladder tumors an exact relocalization of the previously infiltrating tumor spread can be complicated by postreactive alterations, multiple scar tissue or change of surgeons. In this study the results of control transurethral resection of the bladder (TURB) after T1 high grade bladder tumors with the focus on localization and importance of standardized exact documentation were analyzed.
  
  
  METHODS
  From July to February 2012 a control resection was performed in 167 patients due to a T1 high grade bladder cancer. The rates of residual tumor tissue and localization were investigated with standardized tumor documentation.
  
  
  RESULTS
  Out of 167 patients with T1 bladder cancer who underwent a control resection tumor tissue was found in 58.1 % (97 out of 167) and in 85.6 % (83 out of 97) the primary site was affected (41.2 % only at primary site and 44.3 % additionally at other locations). In 11 patients (11.3 %) residual tumor tissue at the initial site was only detected histologically.
  
  
  CONCLUSIONS
  Our results indicate that T1 high grade bladder cancers show a relevant rate of residual tumor tissue at control resection which confirms the clinical guidelines of the European Association of Urology (EAU) on mandatory resection. In most cases the primary tumor site is affected. The standardized bladder tumor documetation allows well-directed control resection also in patients with multiple scars and post-TUR alterations, even when performed by a different surgeon.
