ABSTRACT
Ureteral transitional cell carcinoma [TCC] is the most common cellular type of upper urinary tract cancers which remains undiagnosed for a long time due to its nonspecific symptoms and the unlikelihood of being detected at early stages of investigation. As a result, it is often so well-developed and progressed at the time of admission that it usually leads to a poor survival and high rate of recurrence, even by applying appropriate medical and surgical approaches. Conversely, early diagnosis and therapy is usually associated with a good prognosis. A report of a 65 year old woman with a history of 3 years of recurrent, painless hematuria is presented. The IVP showed a masked left ureteral turtusity associated with mild dilatation of the left ureteral and renal pelvic. The CT scan revealed hypodence foci at the left upper ureter accompanied with dilatation of the left pyelocalyciel system as well as that of the upper and middle parts of the left ureter. Finally, as a result of removing the bladder cuff through a left nephroureterectomy, both ureteroscopy and tissue sampling confirmed a low grade TCC
