Effect of blue‐light cystoscopy on contemporary performance of urine cytology

Abstract

Based on analysis of contemporary data, the sensitivity of cytology for detecting high-grade tumours and CIS remains low. On a per-patient analysis, cytology sensitivity was not affected by the use of advanced cystoscopic techniques except in patients with CIS. The use of cytology as the main adjunct to cystoscopy in patients at high risk can lead to missed opportunities for early detection of recurrence and for determining which patients are not responding to intravesical therapies such as bacille Calmette-Guérin.
