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

Abstract

To determine the additional value of the presence of microscopic haematuria in patients with benign prostatic hyperplasia (BPH). In 750 consecutive patients with BPH urinalysis was performed and the grade of microhaematuria was correlated with other clinical findings. 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. Microscopic haematuria is a frequent finding in assessment of BPH patients and additional tests should only be performed if indicated.
