Lack of visual endoscopic appearance of ureteropelvic urothelial cancer; Is it a deterrence for nephroureterectomy? A case study and literature review

Two case reports are presented with an important question what should be done when an endoscopic appearance of the urotherial lesion is unavailable. as seen in clinical practice, many patients choose nephroureterectomy with frequent follow up procedures. the other question raised is that what should be done when the lesions are ureteroscopically inaccessible. these patients can avail the advantages of radical treatment without accepting the probable as initial form of treatment to evade the risk and detriments of unnecessary additional endoscopic procedures.
