Clinical Experience with URO17® in the Diagnosis and Surveillance of Bladder Cancer.

Objective: To describe the clinical use of URO17®, a noninvasive, urine-based immunocytochemistry assay targeting Keratin 17 (K17), as an adjunct to conventional diagnostic methods for urothelial carcinoma. Materials and Methods: These illustrative cases summarize the real-world use of URO17® in diagnostic workflows for patients presenting with hematuria and those undergoing surveillance for non-muscle invasive bladder cancer (NMIBC). Urine samples were processed via standard immunocytochemistry and interpreted alongside cystoscopic, cytological, and radiographic findings. Discussion: URO17® was used as a complementary diagnostic tool to help guide clinical management. Negative results supported deferral of invasive procedures in selected patients, while positive findings prompted further evaluation when standard tests were inconclusive. Conclusions: In the seven illustrative cases presented, URO17® aided clinical decision-making as part of routine diagnostic and surveillance workflows. The test's integration with existing cytology processes supports its potential role as a noninvasive adjunct for evaluating patients with suspected or recurrent urothelial carcinoma.
