Summary
Upper urinary tract urothelial tumors, primarily transitional cell carcinomas, often present with hematuria. Diagnosis involves imaging like CT and EU, with radical nephroureterectomy as primary treatment, followed by regular surveillance for recurrence.
Area of Science:
- Urology
- Oncology
Context:
- Urothelial tumors of the upper urinary tract are predominantly transitional cell carcinomas.
- These tumors can be multifocal, occurring synchronously or metachronously.
Purpose:
- To outline the diagnosis, treatment, and follow-up of upper urinary tract urothelial tumors.
- To emphasize the importance of accurate staging and regular surveillance.
Summary:
- Patients typically present with hematuria.
- Diagnosis relies on excretory urography (EU) and computed tomography (CT), with staging based on grade and invasion.
- Radical nephroureterectomy with a bladder cuff is the standard treatment.
Impact:
- Early and frequent recurrence necessitates diligent follow-up.
- Regular surveillance using imaging, endoscopy, and cytology is crucial for managing recurrence and assessing tumoral aggressiveness.
