title: Evaluation of new resectoscope loop for transurethral resection of bladder tumors.
abstract: OBJECTIVE
  We evaluate a new resectoscope loop for transurethral resection of bladder tumors.
  
  
  METHODS
  Of 251 transurethral resections in 226 patients 111 were done with a conventional loop and 140 with the Olympus prototype model A2186 resectoscope loop. The quality of specimens provided for histological analysis was compared.
  
  
  RESULTS
  Tissue orientation was preserved and cautery artifact was reduced with the new loop compared to the standard resectoscope loop.
  
  
  CONCLUSIONS
  Compared to a conventional resectoscope loop, the new loop resulted in a better tumor resection and helped facilitate histological evaluation of the tissue specimens.
