Multicolor FISH (UroVysion) facilitates follow-up of patients with high-grade urothelial carcinoma of the bladder.

The aim of the present prospective study was to assess the diagnostic benefit of UroVysion (Vysis-Abbott Laboratories, Downers Grove, IL) in the follow-up of patients with a history of high-grade non-muscle-invasive urothelial carcinoma of the bladder (NMIBC). An unselected cohort of 25 patients with a history of high-grade NMIBC was prospectively followed up by office-based cystoscopy, cytology, and UroVysion in 210 events. The sensitivity and specificity for standard combined cystoscopy and cytology were 78% and 83%, respectively.

Adenocarcinoma of the bladder following nephrogenic adenoma: a case report.

Introduction: Nephrogenic adenomas are generally considered to be benign lesions, but there remains a risk for malignant transformation. Patients with immunosuppression in particular appear to be at a higher risk of malignant disease. We report a case of post-traumatic nephrogenic adenoma in a young patient without immunosuppression, which transformed into an adenocarcinoma of the bladder.
