ホルミウム・ヤグレーザーによる表在性膀胱腫瘍切除術（Holmium : YAG Laser Resection of Bladder Tumor : HoLRBT）の1例

Abstract

We present a case of holmium : YAG laser resection of superficial bladder tumor (HoLRBT). A 73-year-old male was referred to our hospital with elevated prostatic specific antigen. Due to difficulty ofurination, holmium : YAG laser enucleation of the prostate was performed under the diagnosis of benignprostatic hyperplasia. During the surgery, superficial bladder tumor was incidentally identified, and HoLRBT was performed. After the operation, histopathological examination revealed urothelialcarcinoma，G2＞G1，pTa. The patient has been subsequently followed up for 9 months, and there areno evidence of recurrence. Changing the holmium : YAG laser energy setting can potentially be effectiveand safe to approach a superficial bladder tumor.
