Abstract
Endoscopic therapy for the management of upper urinary tract TCC is mainly indicated for patients with an anatomically or functionally solitary kidney, renal insufficiency, bilateral tumors, or severe medical comorbidity. It may be a reasonable alternative to distal ureterectomy with bladder-cuff resection in individuals with low-grade superficial distal ureteral tumors. Although use of this approach has been suggested for treating standard patients with low-grade, low-stage collecting system tumors, this recommendation should not be embraced until more supporting evidence is generated. The efficacy of adjuvant therapy for the prevention of recurrent or progressive disease needs to be defined. If current adjuvant strategies prove ineffective, alternative ones will need to be developed. It is anticipated that advancements in endoscopic technology will facilitate the performance of this type of surgery in the future.
