In this cohort of retrospectively studied patients attending a haematuria clinic, IVU could safely have been omitted without decreasing the overall detection of malignant pathologies. Nevertheless, significant non-malignant pathologies would have remained undiagnosed. The authors suggest that US combined with a MAG III renogram could be considered as a first-line investigation instead of IVU. This is likely to result in maximum detection of malignant and non-malignant conditions, while reducing the radiation exposure to the patient.
