OBJECTIVES: Renal pelvic subepithelial @entity1410 is a rare but significant clinical mimic of @entity5 . Investigation and treatment of this diagnostic problem are uncertain. METHODS: We add 6 @entity1 with this entity to the 15 previously published cases. All 6 were clinically suspected of having @entity5 , and 5 underwent nephrectomy. RESULTS: The most common clinical findings are gross @entity811 (19 of 21 cases) and acute onset of @entity812 (13 of 21 cases). Intravenous urogram usually reveals a filling defect at the ureteropelvic junction. Pathologic findings include massive @entity548 , @entity3041 , cortical @entity1188 , and renomegaly. Two of our @entity1 have previously undescribed clinical associations, including one who was 2 weeks postpartum and another with @entity4145 . In addition, our @entity1 with obstruction is the first with subepithelial @entity1410 to be treated successfully with pyeloplasty. CONCLUSIONS: @entity1410 may be effectively treated with pyeloplasty or partial nephrectomy if distinguished from @entity5 preoperatively. Awareness of this rare entity may allow preoperative identification, but this has not been possible to date.
