The outcome of renal ultrasound in the assessment of 556 consecutive patients with benign prostatic hyperplasia.

PURPOSE: We determined the additional value of renal ultrasonography in the assessment of patients with benign prostatic hyperplasia.

MATERIALS AND

METHODS

Renal ultrasound was performed in 556 consecutive patients with benign prostatic hyperplasia and the results were correlated with other clinical parameters.

RESULTS

Of the patients 14 (2.5%) had dilatation of the renal pelvis, 65 (11.7%) had renal cysts and 1 (0.18%) had renal cell carcinoma. The serum creatinine level appeared to be correlated with dilatation of the renal pelvis. To predict dilatation additional information can be obtained by including the results of the post-void residual measurements.

CONCLUSIONS

Renal ultrasound is indicated only in patients with a specific serum creatinine level and/or post-void residual volume.
