OBJECTIVE: To analyze the clinical characteristics of 2 microm continuous wave laser vaporization resection for the treatment of @entity150 . METHODS: A total of 56 @entity1 with 68 @entity150 underwent 2 microm laser vaporization resection via a transurethral cystoscope under caudal anesthesia. In the operation, the wall of the urinary bladder was vaporized and cut, the muscular layers were removed, and then the specimens were sent for pathological inspection separately. The following variables were recorded: operation time, @entity190 , complications during and after the operation, pathology staging of the @entity5 , and follow-up visit time. RESULTS: All @entity1 endured the operation. The mean surgery time was 8.8 +/- 3.3 minutes (range, 4 to 15 minutes). @entity190 was minimal, no @entity1 experienced an obturator nerve reflection, or a @entity548 after the operation. The pathology staging of the @entity5 were as follows: 40 cases (total 47 @entity5 ) were T1 stage; 16 cases (total 21 @entity5 ) were T2 stage. The follow-up periods were between 12 to 17 months, and the mean period was 14.5 months. @entity5 recurrences were found in 3 cases, and one @entity1 suffered two recurrences, the total recurrence rate was 5.3%. There was no primary recurrence. CONCLUSIONS: The 2 microm continuous wave laser is a new, safe and efficacious method for the treatment of @entity150 . Because the 2 microm laser can vaporize and cut the muscular layers of the bladder finely, it can not only treat superficial @entity150 efficiently, but also treat some types of invasive @entity5 of the bladder.
