後腹膜仮性嚢腫の1例

Abstract

This is a case report of extrarenocapsular urinary pseudocyst seen in a 68-year-old woman who had no history of surgery or trauma, She came to the hospital with an abdominal mass, She experienced severe pain in the flank on the left side two months prior to admission, The above-mentioned mass was noticed one month later which disappeared after a small incision by her home physician, The mass again appeared, however. KUB and IVP showed a stone in the right kidney and hydronephrosis on the left. The mass seemed having no direct anatomical relation with the kidney. Retrograde pyelography met the obstruction at the fourth lumbar vertebral level. A communication was demonstrated between this strictured site and the mass by transfer of the dye. Blood chemistry was normal Blood pressure was 170/100 mmHg. Presence of RBC and WBC in urinalysis was thought to be due to renal lithiasis. Resection of the pseudocyst was performed. Content of the cyst was clear fluid of pale yellow with urine odor. Nephrostomy was placed for urinary diversion.
