The predictive value of microscopic haematuria in patients with lower urinary tract symptoms and benign prostatic hyperplasia.

Objective: To determine the additional value of the presence of microscopic haematuria in patients with benign prostatic hyperplasia (BPH).

Methods: In 750 consecutive patients with BPH urinalysis was performed and the grade of microhaematuria was correlated with other clinical findings.

Results: Microscopic haematuria was found in one third of the patients. Only 3 had a bladder tumour and 49 patients had urinary calculi for which only one patient required treatment. There was no correlations between any clinical parameter and the finding of microscopic haematuria.

Conclusion: Microscopic haematuria is a frequent finding in assessment of BPH patients and additional tests should only be performed if indicated.
