Reflex anuria following retrograde pyelography: A case report and literature review

Abstract

A case of acute kidney injury due to reflex anuria that was caused by retrograde pyelography and required temporary hemodialysis is reported. An 83-year-old Japanese woman presented with anuria 2 days after undergoing bilateral retrograde pyelography for the investigation of gross hematuria. Retrograde pyelography showed no apparent abnormality, such as malignancy or urolithiasis, but pyelorenal extravasation of contrast medium was remarkable. Her anuria improved promptly after hemodialysis, allowing her treatment to conclude with only one hemodialysis session, and a normal renal function was restored with no sequelae. The details of this case and a review of the relevant literature are presented.
