[Initial experience of partial cystectomy in treatment of bladder tumor by 2 microm continuous wave laser].
OBJECTIVE
To analyze the clinical characteristics of partial cystectomy in treatment of bladder tumor by 2 microm continuous wave laser.


METHODS
A total of 18 patients with 21 bladder tumors treated by 2 microm laser via transurethral under sacral block. The diameters of tumors were between 1-3 cm. In the operation, we vaporized and cut whole wall of bladder, dissected the muscular layers from connective tissue, and sent them for pathology inspection. We reviewed these following variables: operation time, blood loss, complications during and after the operation, pathology staging of the tumor and follow-up visit.


RESULTS
All the patients were tolerated in the operation. The mean operative time was (7.4 +/- 3.3) min (range, 5-12 min). Blood loss in the operation was minimal. No patient experienced an obturator nerve reflection or a hemorrhage after the operation. One case has urine leakage. The pathology staging of the tumors were as follows: T1 stage 15 cases, total 18 tumors; and T2 stage 3 cases, total 3 tumors. The followup periods were between 3 to 6 months, and the mean period was 4.5 months. There was no recurrence in situ.


CONCLUSIONS
The 2 microm laser not only can vaporize and cut the wall of bladder finely, but also can dissect the muscular layers from connective tissue efficiently. So it can be partial cystectomy in the treatment of bladder tumor.
