Abstract
-
We report on a patient with spontaneous rupture of hemorrhagic renal cyst into the pyelocaliceal system. He had no history of trauma, bleeding disorders, urinary tract infection or urinary tract obstruction. Gross hematuria followed by left flank pain occurred 1 day prior to admission. Although radiologic findings were suggestive of rupture of renal cyst into the calyx or calyceal diverticulum. exclusion of malignant disease or renal carbuncle was difficult. He was managed by partial nephrectomy. Microscopic findings revealed ruptured cyst lined with low cuboidal epithelium without evidence of malignancy.
