title: Ureteroscopic approach to upper-tract urothelial tumors.
abstract: Transitional-cell carcinoma (TCC) of the upper urinary tract has traditionally been managed by nephroureterectomy, whereas nephron-sparing surgery has been reserved for those few patients with solitary kidneys or bilateral lesions. However, with the introduction of improved diagnostic and therapeutic technology, including smaller ureteroscopes and working instruments, and the concomitant ease of surveillance, ureteroscopic treatment of upper-tract urothelial tumors has become a reasonable alternative to open operative intervention in patients requiring conservative management. Furthermore, as preoperative grading and staging have improved, ureteroscopic treatment of upper-tract urothelial tumors is assuming an increasingly important role in the management of some patients who might have otherwise been treated with a nephroureterectomy. The technique of ureteroscopic resection is described in detail.
