[Correlation of benign prostatic hyperplasia with hyperlipemia].

OBJECTIVE

To investigate relationship between benign prostatic hyperplasia (BPH) and hyperlipemia, and to clear out possible factors related to BPH etiology.

METHODS

A total of 462 cases of BPH diagnosed by pathological examination were studied retrospectively.

RESULTS

Of 462 cases, BPH with hyperlipemia was noted in 232 cases (50.22%). In comparison with the data of simple BPH, both prostate volume (P = 0.029) and residual urine (P = 0.03) were significantly increased in the BPH patients with hyperlipemia. Statistical analysis regarding the effects of different components of serum lipid on BPH clinical factors showed that the level of high density lipoprotein was significantly associated with both the enlargement of prostate volume (P < 0.05) and increasing of serum PSA (P < 0.05) Further study indicated that hypertension was demonstrated in 39.2% patients of BPH with hyperlipemia. Hyperlipemia accompanied with hypertension in BPH patients was significantly related to increased IPSS (P = 0.004).

CONCLUSION

The situation of BPH with hyperlipemia is frequently noted in clinics, and the decreased level of high-density lipoprotein is significantly associated with the enlargement of prostate volume. Co-existence of hypertension with hyperlipemia in BPH patients greatly worsens the lower urinary tract symptoms (LUTS) of BPH. Hyperlipemia may be one of the risk factors in the processes of BPH growth and progression.
