精管皮膚尿瘻症例

Abstract

A case of urethro-vaso-cutaneous fistula based on urethrovasal reflux was presented. A 27-year-old man was admitted to the Kinki University Hospital on August 22, 1980. He had a history of urinary leakage from the right scrotum and scrotal swelling. This annoying leakage appeared when he bore to urinate. There was an orifice which was about 1mm in diameter on right scrotum. A cord like structure was palpated between this fistula and the vas deferens. A urethrocystogram demonstrated bilateral vesicoureteral reflux and right urethrovasal reflux. A fistelogram depicted right epididymis, vas deferens and posterior urethra. After his urination following bladder instillation of indigocarmine solution, endoscopy revealed a jet of blue dye from the ejaculatory duct. Young et al. first described on urethro-vaso-cutaneous fistula in 1926. Fourteen cases of urethro-vaso-cutaneous fistula including our case were reviewed and the pathophysiolcgy of retrograde urination was discussed.
