    Prevalence of carotid artery calcification on panoramic radiographs in patients with renal stones
    (2013) Üstün, İhsan; İnci, Mehmet; Demirtaş, Abdullah; Şişman, Yıldıray; Gökçe, Cumali; Tarım Ertaş, Elif
    Aim: To determine the prevalence of carotid artery calcification (CAC) detected in routine dental radiography (PRs) in patients with kidney stones (KSs) and to investigate the relationship between CAC-atherosclerosis and KSs. Materials and methods: A total of 108 patients with renal stones were included in the present study. A history of renal colic, with confirmed hematuria and voiding of the calculus, radiographic evidence of KSs, or previous surgical and endoscopic removal of KSs, was used to define the nephrolithiasis. KS patients were evaluated by PR in terms of the presence of CAC. Subjects with either unilateral or bilateral CAC on these radiographs were identified. Results: Of the 108 patients included in the data analysis, 18 (16.6%) were detected as having CAC upon PR; of these, there were 8 males (11.5% of all males) and 10 females (25.6% of all females) (P > 0.05). There was no significant difference between the patients with CAC and the patients without CAC in any aspect of biochemical parameters, and also in the history of predisposing factors (P > 0.05). The CAC prevalence (16.6%) was significantly higher in patients with KSs when compared to the normal population (5.06%) in our previous study (P > 0.05). Conclusion: Our study shows that CAC is significantly higher in patients with KSs when compared to the normal population. This study may draw the attention of clinicians to the fact that patients with KSs should be evaluated further for atherosclerosis and treated for vascular risk factors.

    Relationship between urolithiasis and diastolic functions of the heart
    (2013) İnci, Mehmet; Şarlı, Bahadır; Çelik, Ahmet; Demirtaş, Abdullah; Baydilli, Numan; Akpek, Mahmut; Kaya, Mehmet Güngör
    Aim: Relationships between urolithiasis and cardiovascular disorders were evaluated in several studies. In this study, we aimed to investigate whether urolithiasis causes a decline in cardiac diastolic functions. Materials and methods: Seventy-seven consecutive patients and 40 age- and sex-matched controls were included in this study. Transthoracic echocardiography was performed for all patients. Results: There were 77 patients (mean age: 45 ± 14 years, 64% male) in the stone-formers group and 40 patients (mean age: 43 ± 12 years, 63% male) in the control group. Peak E wave velocity (0.67 ± 0.21 to 0.85 ± 0.18, P = 0.001) and E/A ratio (0.97 ± 0.21 to 1.37 ± 0.27, P = 0.001) were significantly lower in stone formers than in control patients. In addition, peak A wave velocity (0.74 ± 0.15 to 0.69 ± 0.14) was significantly higher in stone formers than control patients (P = 0.01). Diastolic dysfunction was more frequent in stone formers than control patients (P = 0.015). Conclusion: This study shows that there is a link between urolithiasis and cardiac diastolic dysfunction. Urolithiasis should therefore be recognized in evaluation of patients with diastolic dysfunction.
