Relationship Between Chronic Periodontitis and Lower Urinary Tract Symptoms/Benign Prostatic Hyperplasia

We investigated the relationship between lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and chronic periodontitis (CP).

A total of 103 middle-aged men who had received a health checkup were included. All participant data were prospectively collected. CP was defined as a 30% increase in the number of probed sites with a clinical attachment level of ≥4 mm among all probed sites. LUTS/BPH were assessed using transrectal ultrasonography, the International Prostate Symptom Score (IPSS), uroflowmetry, and postvoiding residual urine volume.

The median age, IPSS, prostate volume, and maximal flow rate were 55.0 years, 9.0, 29.0 mL, and 20.0 mL/sec, respectively. In addition, the prevalence of CP was 27.2%. The IPSS total, IPSS voiding, IPSS storage, and quality of life (QoL) scores were significantly higher in patients with CP (median [interquartile range, IQR]-IPSS total: 8.0 [5.0-13.5] vs. 12.0 [7.5-20.5], P=0.004; IPSS voiding: 5.0 [2.0-9.0] vs. 8.5 [4.0-15.0], P=0.002; IPSS storage: 3.0 [2.0-5.0] vs. 4.0 [3.0-6.0], P=0.021; QoL: 2.0 [1.0-3.0] vs. 3.0 [2.0-4.0], P=0.015). Additionally, the average flow rate was significantly lower in patients with CP (median [IQR] (mL/sec): 9.0 [8.0-13.0] vs. 8.0 [6.0-11.0], P=0.047). After adjustment for age, testosterone level, prostate volume, glucose level, cholesterol level, and waist circumference, the IPSS total and voiding scores were significantly and positively related to CP (IPSS total: odds ratio [OR], 1.141; 95% confidence interval [CI], 1.045-1.245; P=0.003; IPSS voiding: OR, 1.243; 95% CI, 1.092-1.415; P=0.001).

Our data suggest that LUTS/BPH is significantly related to CP.
