What initial investigations should I perform for a patient presenting with visible haematuria?

For a patient presenting with visible haematuria, initial investigations should be guided by the patient's sex, age, and any associated symptoms. If a urinary tract infection (UTI) is suspected, a urine sample for culture and susceptibility testing should be sent before starting antibiotic treatment, where appropriate NICE CKS. For men with visible haematuria, a prostate-specific antigen (PSA) test and digital rectal examination (DRE) should be considered NICE NG12. For women aged 55 years and over with visible haematuria accompanied by low haemoglobin levels, thrombocytosis, high blood glucose levels, or unexplained vaginal discharge, a direct access ultrasound scan should be considered NICE NG12.
