腹部圧迫法によるIVPにおいて腎盂外溢流をきたしたと考えられる1例

Abstract

Peripelvic extravasation during retrograde pyelography is not rare, but that during intravenous pyelography is rare. A case of a 32-year-old man is reported. The urinalysis showed microscopic hematuria. Intravenous urography was done with abdominal compression. He complained of a sudden colicky pain in the left flank after 10 or 12 minutes. The pyelogram of the left kidney showed peripelvic extravasation and pyelolymphatic backflow. The retrograde pyelogram of the left kidney showed same changes. Drip infusion pyelography and renal angiography showed normal, and renal function was normal. Even in the normal kidney in this case, as the intrapelvic pressure increased suddenly, peripelvic extravasation occurred at the microscopic tear in the forniceal calices and then extravasated contrast material was absorbed by lymphatics.
