BCG膀胱内注入療法により膀胱保存が可能となつた多発性乳頭状膀胱腫瘍症例

CONSERVATIVE TREATMENT OF MULTIPLE PAPILLARY TUMORS OF THE BLADDER WITH INTRAVESICAL BACILLUS CALMETTE-GUERIN

　他院にて膀胱全摘をすすめられた多発性乳頭状膀胱腫瘍の2例にBCG膀胱内注入療法を施行したところ，著明な腫瘍数の減少が得られ，残存腫瘍を経尿道的に切除することにより，膀胱保存が可能となつた。

We report 2 patients with superficial papillary tumors of the bladder who were treated with intra-vesical bacillus Calmette-Guerin (BCG). In both cases numerous tumors were located in the whole bladder mucosa and not amenable to transurethral resection. These patients initially received a total of 12 intravesical instillations of 80mg BCG (Tokyo 172 strain) with marked reduction in the number of tumors and subsequently underwent a complete transurethral resection of the residual tumor. Thus, intravesical BCG is useful in the treatment of multiple papillary tumors of the bladder that are not amenable to transurethral resection.
