    Association of erectile dysfunction and urolithiasis
    (Edizioni Scripta Manent s.n.c., 2014) Otunctemur A.; Ozbek E.; Cakir S.S.; Dursun M.; Polat E.C.; Ozcan L.; Kose O.; Besiroglu H.
    Objectives: In recent years, it has been shown that there is association between metabolic syndrome and urinary stone disease. Stone disease and erectile dysfunction (ED) are considered as systemic diseases which are associated with hormonal and metabolic disorders. Therefore we investigated the relationship between ED and urinary tract calculi.Material and methods: 98 male patients with urolithiasis and 59 randomly selected male patients without stone disease were included in the study. Serum testosterone (T) levels were measured and International Index of Erectile Function (IIEF)-15 questionnaire forms were used to assess ED.Results: The prevalence of ED was found 29% (29 patients) in the urolithiasis group. Sixty-nine patients (71%) had no ED; 16 (16.3%) had mild, 5 (5.1%) had moderate and 8 (8.2%) had severe ED. None of the patients in the control group had severe or modarete ED, six patients (10.2%) had mild ED. Serum T levels were detected at the level of biochemical hypogonadism on 13 patients with stones (13.3%) and T levels were detected at the lower limit in 18 (18.3%) patients.Conclusion: In our study we have shown that ED and low T levels are significantly associated with urolithiasis. We propose that the patients with urolitiasis should be evaluated for ED and hypogonadism.

    Beneficial effects montelukast, cysteinyl-leukotriene receptor antagonist, on renal damage after unilateral ureteral obstruction in rats
    (Brazilian Society of Urology, 2015) Otunctemur A.; Ozbek E.; Cakir S.S.; Dursun M.; Cekmen M.; Polat E.C.; Ozcan L.; Somay A.; Ozbay N.
    Introduction: Ureteral obstruction is a common pathology and caused kidney fibrosis and dysfunction at late period. In this present, we investigated the antifibrotic and antiinflammatory effects of montelukast which is cysteinyl leukotriene receptor antagonist, on kidney damage after unilateral ureteral obstruction(UUO) in rats. Materials and Methods: 32 rats divided four groups. Group 1 was control, group 2 was sham, group 3 was rats with UUO and group 4 was rats with UUO which were given montelukast sodium (oral 10 mg/kg/day). After 14 days, rats were killed and their kidneys were taken and blood analysis was performed. Tubular necrosis, mononuclear cell infiltration and interstitial fibrosis scoring were determined histopathologically in a part of kidneys; nitric oxide(NO), malondialdehyde(MDA) and reduced glutathione(GSH) levels were determined in the other part of kidneys. Urea-creatinine levels were investigated at blood analysis. Statistical analyses were made by the Chi-square test and one-way analysis of variance (ANOVA). Results: There was no difference significantly for urea-creatinine levels between groups. Pathologically, there was serious tubular necrosis and fibrosis in group 3 and there was significantly decreasing for tubular necrosis and fibrosis in group 4(p<0.005). Also, there was significantly increasing for NO and MDA levels; decreasing for GSH levels in group 3 compared the other groups(p<0.005). Conclusion: We can say that montelukast prevent kidney damage with antioxidant effect, independently of NO.

    Possible association between erectile dysfunction and osteoporosis in men
    (2015) Dursun M.; Özbek E.; Otunctemur A.; Cakir S.S.
    Sexual dysfunction in general and erectile dysfunction (ED) in particular significantly affect men's quality of life. Some patients who have ED, also develop osteoporosis. So, in this study we investigated the relationship between erectile dysfunction and osteoporosis in men. 95 men with erectile dysfunction and 82 men with normal sexual function were included in the study. The men's sexual functions were evaluated by International Index of Erectile Function-5 items (IIEF-5). All men received a Dual Energy X-ray Absorptiometry (DEXA; Hologic) scan to measure bone mineral density (BMD) for osteoporosis. Chi-square test was used for statistical analysis. Mean age was 53.5 (38-69) in ED group and 50.1 (31-69) in control group. In ED group the men have lower T score levels than those of the control group. In conclusion, the men who have erectile dysfunction were at more risk for osteoporosis. The results of the present study demonstrate that the men with erectile dysfunction have low bone mineral density and they are at higher risk for osteoporosis. Because of easy and noninvasive evaluation of osteoporosis, patients with ED should be checked for bone mineral density and osteoporotic male subjects should be evaluated for ED.
