HardMicrohematuriaPersistent invisible haematuria with A3 albuminuriaMSRA

A 59-year-old man has incidental non-visible haematuria identified during a hypertension review. He has no visible haematuria, dysuria, urinary frequency, loin pain, fever, weight loss, urinary tract infection symptoms, recent instrumentation or vigorous exercise. He stopped smoking 8 years ago (28 pack-years). Three correctly collected early-morning urine samples over 10 weeks show blood 2+, blood negative and blood 1+ on reagent strip. All midstream urine cultures show no significant growth. Urine ACR is 38 mg/mmol and 42 mg/mmol on repeat early-morning testing 12 weeks apart. His eGFR is stable at 86 mL/min/1.73 m² and blood pressure is 128/74 mmHg on ramipril 10 mg daily. Full blood count shows neutrophilia, with white cell counts of 12.4 × 10⁹/L and 12.7 × 10⁹/L 3 weeks apart. He is otherwise well and there is no clinical focus of infection. What is the most appropriate next management plan?

Correct answer: ERefer for specialist nephrology assessment and arrange review of the persistent neutrophilia with appropriate safety-netting

This man has persistent invisible haematuria because 2 of 3 appropriately collected reagent-strip tests are positive. He also has confirmed A3 albuminuria, with ACR persistently above 30 mg/mmol, and haematuria. NICE CKD guidance recommends specialist assessment for adults with ACR above 30 mg/mmol together with haematuria, irrespective of preserved eGFR. Nephrology referral is therefore indicated. He does not meet the NICE suspected cancer pathway criterion for bladder cancer: unexplained non-visible haematuria with either dysuria or raised white cell count requires age 60 years or over. His smoking history and neutrophilia make bladder malignancy an important consideration and justify careful review and safety-netting, but they do not meet this specific urgent referral threshold at age 59. A direct ultrasound is not the recommended substitute for the indicated nephrology referral. Annual monitoring applies to persistent invisible haematuria in the absence of proteinuria; it is inappropriate with confirmed A3 albuminuria. Urine microscopy should not be used to confirm a positive reagent-strip result in this setting.
