[When is it meaningful to investigate hematuria? Macroscopic hematuria--investigate always. Microscopic hematuria--symptoms and age decide].

All patients (n = 578) referred during one year and for whom hematuria was mentioned in the referral form were monitored following urological evaluation including urography and cystoscopy. Evaluation of macroscopic hematuria was often associated with significant findings at both urography (stones) and cystoscopy (bladder tumors). The situation was the same even if not as pronounced for evaluation of microscopic hematuria with concomitant urinary tract symptoms. The evaluation of asymptomatic microscopic hematuria was, however, very rarely associated with significant findings, which were moreover totally lacking among women and younger males.
