Q

Investigation - gold standard for haematuria (and others to consider)

A

CT IVP gold standard
Urine MCS
Bloods - FBE, UEC, coags
Renal tract uSS - if <50 or renal impairment

○ Heavy exercise (avoid for previous 48 hours prior to testing)
○ Recent UTI
○ BPH
○ Catheterisation/Biopsy (avoid in previous 6 weeks prior to testing)
