Resumen
Positive UroVysionTM fluorescence in situ hybridization (U-FISH) is generally considered urothelial carcinoma (UC). However, in our clinical practice, we found that U-FISH also showed positive findings in non-urothelial carcinomas or even metastatic carcinomas. A review is needed to increase awareness to avoid misdiagnosis. This review focuses on summarizing the research status of U-FISH in UC, non-urothelial carcinoma and metastatic tumor, so as to strengthen urologists? comprehensive understanding of the application value of U-FISH and better complete the accurate diagnosis of urological cancers.
