神経因性膀胱に合併した膀胱周囲膿瘍の2症例

Abstract

We report two cases of perivesical abscess associated with neurogenic bladders. One patient suffered from diabetic neurogenic bladder, and the other spinal cord injury. Both patients had an uninhibited contraction at the low capacity on cystometry. They complained of difficulty in micturition and presented with large lower abdominal tumors. Although the extravasation of contrast medium was not confirmed on cystography, we believe that the perivesical abscess was the consequence of urinary leakage out of the bladder. The abscesses disappeared after drainage. We have discussed the possible mechanism involved in the abscess formation which occurred in the neurogenic bladders.
