Endoscopic management of upper tract transitional cell carcinoma

Area of Science:

• Urology
• Oncology

Background:

• Upper urinary tract transitional cell carcinoma (TCC) represents up to 10% of upper tract neoplasms.
• Nephroureterectomy is the traditional gold standard for managing upper tract TCC.

Purpose of the Study:

• To review current techniques, indications, contraindications, and outcomes of endoscopic management for upper tract TCC.
• To highlight the importance of patient selection in endoscopic treatment strategies.

Main Methods:

• Review of current literature on endoscopic management of upper tract TCC.
• Discussion of percutaneous (antegrade) and retrograde endoscopic approaches.
• Analysis of patient selection criteria including tumor characteristics and comorbidities.

Main Results:

• Technological advancements enable endoscopic management via flexible ureterorenoscopy (retrograde) and percutaneous approaches.
• Endoscopic methods allow for chemotherapeutic agent instillation.
• Successful outcomes depend heavily on careful patient selection and compliance.

Conclusions:

• Endoscopic management is a viable option for carefully selected upper tract TCC patients, particularly those with small, low-grade tumors or specific comorbidities.
• Further large randomized trials are needed to establish long-term efficacy.
• Patient motivation and compliance are essential for successful long-term results.
