title: [Transurethral partial cystectomy using a 2 microm continuous wave laser in treatment of bladder carcinoma: 1-year follow-up].
abstract: OBJECTIVE
  To summarize and analyze the clinical features of bladder tumor patients who received transurethral partial cystectomy by 2 microm continuous wave laser, in 1 year post operation follow-up visits.
  
  
  METHODS
  From December 2007 to May 2008, 47 bladder carcinoma patients were treated with 2 microm laser transurethrally under sacral block. Operation characteristics, operation time, intraoperative hemorrhages and postoperative complications, and pathology staging of the tumor were observed and postoperative follow-up visits were performed.
  
  
  RESULTS
  All of the operation procedures were successful. The surgery time was 5 to 15 minutes. Blood loss in the operation was minimal. There was no obturator nerve reflection, and no hemorrhaging was detected after the operation. The pathological stages can be judged correctly with the obtained specimens. There was one case with peritoneum perforation. The patients received 12 to 17 months of postoperative follow-up visits, and there was no recurrence at the resection site. The survival rate was 100%.
  
  
  CONCLUSIONS
  Transurethral partial cystectomy in the treatment of bladder tumor by 2 microm continuous wave laser is a safe, efficient and effective method. The tumor and all the basal part of bladder wall could be excised completely and the pathological stages can be judged correctly using these specimens to fulfill partial cystectomy for the treatment of bladder carcinoma.
