ABSTRACT
PURPOSE:
To our knowledge we established a new technique to vaporize and incise the full-thickness bladder wall and peel off the entire muscular layers with a 2 microm continuous wave laser to treat bladder carcinoma. MATERIALS ANDMETHODS:
Nine patients were treated transurethrally with a 2 microm laser under sacral block. This 2 microm laser was used to incise the full-thickness bladder wall around the tumors. The entire bladder wall was peeled between the detrusor muscle layer and outer connective tissues. Tumors with full-thickness detrusor muscle layers at the base were removed together and sent for pathological examination. Intraoperative hemorrhage and postoperative complications were observed, and pathological staging and postoperative followup were performed.RESULTS:
All operations were successful. Mean +/- SD operative time was 8.7 +/- 2.6 minutes (range 7 to 15) per patient. Perioperative blood loss was minimal. There was no obturator nerve reflection and no hemorrhage was detected after surgery. Bladder perforation occurred in 1 case. Pathological stage of the tumors was T1 and T2a. Patients were followed for 6 to 9 months postoperatively with no recurrence at the resection site. This series included highly selected patients treated by a single high volume surgeon.CONCLUSIONS:
To our knowledge this is the first report of a 2 microm laser used to treat bladder carcinoma. It can be applied to precisely vaporize and incise the full-thickness bladder wall and peel it between detrusor muscle layers and outer loose connective tissues, thus completing partial cystectomy for bladder carcinoma.
