Abstract

What's known on the subject? and What does the study add?

Urine cytology is frequently used by urologists to evaluate patients with microscopic or gross haematuria. The results of urine cytology can be used as impetus to perform or triage further diagnostic studies, e.g. cystoscopy.

The impact of urine cytology results on patient care warrants clarifying. This evidence-based medicine article explores how positive or negative urine cytology will impact the probability that a patient has urothelial carcinoma of the bladder before cystoscopy.
