Moderate-to-high cardiovascular risk is associated with increased lower urinary tract storage symptoms in patients...

To assess the association between cardiovascular risk (CVR) and lower urinary tract symptoms (LUTS) in men with benign prostatic enlargement (BPE).

We enrolled a consecutive series of men with LUTS/BPE. International Prostate Symptom Score (IPSS), voiding (vIPSS) and storage (sIPSS) subscore and prostate volume were evaluated. We defined CVR according to the European Association of Cardiologist Guidelines, and metabolic syndrome (MetS) according to the Adult Treatment Panel III (ATP III).

A total of 509 patients were enrolled. Median age was 66 years (IQR: 60-72), IPSS 9 (IQR: 5-15), vIPSS 5 (IQR: 2-9), sIPSS 4 (IQR: 2-7), Prostate volume was 54 cc (IQR: 40-73). Overall 309/509 (60.7%) patients had a moderate/high CVR and 128/509 presented MetS (25.1%). 297/509 (58.3%) men had an IPSS>7 and 282/509 (55.4%) a sIPSS>3. Men with moderate-to-severe CVR had higher IPSS (9; IQR: 4-14 vs. 10; IQR: 5-16; P=0.01), higher vIPSS (6; IQR: 2-9 vs. 4; IQR: 2-8; P=0.06) and higher sIPSS (4; IQR: 2-8 vs. 3; IQR: 1-6; P=0.005) when compared with no/low CVR patients. On multivariate analysis CVR was associated with an increased risk of IPSS>7 (OR=1.794; 95% CI: 1.111-2.888; P=0.01) and sIPSS>3 (OR=1.593; 95% CI: 1.101-2.555; P=0.04).

A moderate/high CVR is associated with an increased risk of LUTS, particularly storage LUTS. Although the pathophysiology is yet to be understood, it can be assumed that an increased CVR may be associated with LUTS/BPE presence.
