title: Upper urinary tract lipoma: A case report.
abstract: Upper urinary tract (UUT) benign tumours are rare. We present a case of UUT lipoma in a 41-year-old man with left flank pain. A computed tomographic urography scan revealed an irregular thickening of the left renal collecting system wall extending from the upper calices to the renal pelvis. The diagnosis of UUT was made and the patient underwent a nephroureterectomy with bladder cuff excision, as standard treatment. However, macroscopic and histological examination revealed a lipomatous tumour with no sign of malignancy. To our knowledge this is the first reported case of its kind of a UUT managed first with a minimally invasive approach.
