脊髄損傷男子に発生した後天性前部尿道憩室の1例

Abstract

A case of acquired diverticulum of the male anterior urethra is reported. A 67-year-old man with Pott paralysis caused by tuberculous spondylitis, visited our clinic due to recurrent urinary tract infection. He had used a condom penile sheath to collect urine. Voiding and retrograde cystourethrograms revealed anterior urethral diverticulum. Magnetic resonance imaging (MRI) clearly demonstrated diverticulum and corpus cavernosum penis, but corpus spongiosum penis was not defined. Urethroscopy showed diverticulum in the shape of partially dilated urethra with normal urethral mucosa. After diverticulectomy, self catheterization was endorsed. Histological study of removed diverticulum revealed squamous epithelium and fibrous connective tissue in the wall. The urethral diverticulum of this patient might have arisen from the elevated urethral pressure caused by the condom penile sheath.
