New guidelines (2012) have been published by the American Urological Association (AUA) for the investigation of symptomatic haematuria. There are several differences between these guidelines and UK guidelines. For example, UK guidelines suggest investigating all patients with cystoscopy over 40 years old, whereas AUA guidelines suggest over 35. AUA guidelines suggest CT urogram or MR urogram imaging, but UK guidelines do not specify. AUA guidelines suggest full reevaluation of persistent asymptomatic haematuria within 3 to 5 years, whereas UK guidelines suggest limited annual reevaluation with blood pressure and urinary protein:creatinine testing, with full evaluation only in the presence of symptoms or visible haematuria.
