[Comparison of endoscopic irsection and vaporization for superficial bladder cancer]

To evaluate the method and clinical value of endoscopic surgery by comparing endoscopic resection and vaporization for superficial bladder tumor.

396 patients with superficial bladder papillary transitional cell carcinoma were treated by endoscopic therapy. 180 patients (Group A) were treated by transurethral resection of bladder tumor (TURBT) and 216 (Group B) by transurethral vaporization of bladder tumor (TVBT). Periodic postoperative intra-vascular instillation of chemotherapy was given to both groups. Operating time, amount of bleeding during operation, complications and recurrence rate were compared.

In group B, the amount of bleeding and complications during operation were lower than those in group A, but TVBT rated better by clearer view and simplicity in maneuver. The operating time, recurrence rate in group B were similar to those in group A.

Transurethral vaporization of bladder cancer, with simplicity in maneuver, less bleeding and fewer complications, rates better in effectiveness and clinical value than resection.
