Photodynamic Diagnosis of Upper Tract Urothelial Carcinoma Using Fluorescence Endoscopy and Oral 5-ALA
A Phase II Study on Photodynamic Diagnosis of Urological Cancer in the Upper Urinary Tract Using Fluorescence Endoscopy With Cystoscopy and Ureteroscopy With 5-ALA
Henry Ford Health System
10 participants
Apr 1, 2026
INTERVENTIONAL
Conditions
Summary
This study is evaluating whether a medication called 5-aminolevulinic acid (5-ALA), approved by the FDA for use in brain surgery, can help improve the visibility of upper tract urothelial tumors during surgery. Patients undergoing ureteroscopic tumor resection will receive 5-ALA prior to surgery, and surgeons will use special blue light to help identify abnormal tissue that might not be seen under standard white light. The goal is to assess whether this technique can enhance tumor detection and removal.

Interventions
Participants will receive a single oral dose of 5-aminolevulinic acid (20 mg/kg) approximately 2 to 4 hours prior to surgery. The goal is to evaluate the feasibility of using fluorescence cystoscopy with blue light to improve tumor detection and visualization during ureteroscopic resection of upper tract urothelial carcinoma.
