Abstract

Retroperitoneal sarcoma is a rare tumor accounting for 1-2% of all solid malignancies. These tumors are usually large when diagnosed because of their typically silent nature and should be distinguished from other retroperitoneal masses for adequate management. In spite of an apparent complete resection which is the only potential curative treatment, the high rate of local recurrence is the major problem of retroperitoneal sarcoma; therefore, patients with high-grade tumors should undergo regular and continuous follow-ups. Postrenal acute kidney injury (AKI) results from a urinary outflow tract compression due to the mass effect of retroperitoneal sarcoma, which is one of less common causes of postrenal AKI and has not been reported in Korea. We report a case that an 81-year-old-woman with undifferentiated retroperitoneal sarcoma presented with post-renal AKI and improved after complete resection.

Key Words: Retroperitoneal neoplasm, Acute renal failure
