According to European Association of Urology (EAU) guidelines, urinary cytology is most helpful in diagnosing high-grade tumors and carcinoma in situ (CIS). Low-grade, noninvasive tumors may be missed by routine cytologic analysis. The guidelines caution that cystoscopy is still required and cannot be replaced by cytology or any other noninvasive test. [69] National Comprehensive Cancer Network (NCCN) guidelines state that urine cytology may be obtained around the time of cystoscopy. [1]
