The polyp was excised and the kidney spared. The diagnosis and management of fibroepitheli- al polyps are discussed and the literature reviewed. However, patients with solitary kidneys, bilateral tumors, renal insufficiency, or medical comorbidities require more conservative management. When the TCC is low grade, it would be desirable to manage such tumors endoscopically. All tumors have been managed successfully without evidence of progression.
Recurrence is frequent in some patients and requires repeat treatment and vigilant surveillance.
It can also ablate tissue including neoplasms. Because the laser light can be carried through small flexible quartz fibers, it is ideally suited for use through small-diameter rigid and flexible ureteroscopes in the upper urinary tract. Although care must be used in application of the laser, the combination of fine control and limited tissue penetration allow it to be used safely in the ureter. Techniques for stone fragmentation, tumor ablation and stricture incision are described in detail. The authors submit a report on four patients with urothelial carcinomas of the upper urinary pathways, as in each of them the development of the disease was interesting.
