Significance of the evaluation of asymptomatic microscopic haematuria in young men

Abstract

To evaluate the extent of diagnostic evaluation that is necessary in young men with asymptomatic microscopic haematuria.A group of 157 men (mean age 24.8 years [range 18-53]) who presented with asymptomatic haematuria were investigated with repeated urine analysis. Addis count, urinary cultures, blood tests, ultrasonography, pyelography, cystourethroscopy and finally renal biopsy.The results showed pathological findings in 31.2% of patients. Of the 157 individuals, 33.1% did not complete the study. In 14.6% urological disease was found, including two patients with urothelial cancer. Renal biopsy detected glomerulopathy in 16.5% of all patients. IgA nephritis being the most common diagnosis (42% of all biopsies).Even in young patients, microscopic haematuria should be investigated and followed thoroughly. Renal biopsy seems to be optional: once a diagnosis is established repeated and unnecessary examinations can be avoided.
