膀胱憩室に対する憩室口拡張術の1例

A CASE WITH BLADDER DIVERTICULUM MANAGED BY TRANSVESICAL ENLARGEMENT OF ITS ORIFICE

緒言

　膀胱憩室に対する手術法としては，専らその摘除術が胱胱内または外式に，あるいは両者の混合による方法によつて行なわれることが多く，憩室粘膜剥離術がこれにつぐと思われる。われわれは最近，血尿，混濁尿および2回排尿を主訴として来院した23歳，男性の先天性と思われる憩室例に対して，経膀胱的にその憩室口の拡張のみを行ない，術後6ヵ月以上経過した現在，尿所見，排尿効率その他の臨床症状に異常をみとめていないので，その経過について報告したい。

A 23-year-old man with a congenital bladder diverticulum, complaining of symptom as cystitis, was treated only by transvesical enlargement of its orifice. This management was employed because there were neither a stone nor a tumor in the diverticulum and it was thought that if this diverticulum was totally removed, his bladder volume would not be large enough for normal urination.

The operative method was transverse cutting of the thickened muscular bar surrounding the orifice of diverticulum, adding resection of its small area.
