    Is polycystic ovarian syndrome a risk factor for urolithiasis?
    (Springer, 2013) Kaygusuz, Ikbal; Karatas, Omer Faruk; Kafali, Hasan; Cimentepe, Ersin; Unal, Dogan
    Urinary stone disease is a complex multifactorial disorder influenced by both intrinsic and environmental factors. It is generally known that age and sex are risk factors for urinary stone disease. Also men have higher mean urinary oxalate concentrations than women. In addition, in animal and human studies, testosterone has been shown to increase the formation of urinary stones. This suggests that sex hormones are considered to be involved in the pathogenesis of stone disease. Polycystic ovary syndrome (PCOS) is one of the most frequent endocrine disorders of women in the reproductive age, affecting 5-10 % of women in this life span. It is characterized with chronic anovulation\oligo-ovulation, clinical or biochemical evidence of hyperandrogenism and polycystic ovaries on ultrasound examination. Hyperandrogenism, the main feature of PCOS, may trigger the urinary stone formation besides hirsutism, alopecia and acne. Therefore, we hypothesize that PCOS accompanied by hyperandrogenism may be a risk factor in the formation of urinary stone disease.

    The comparison of the influence between two different bowel preparation methods on sepsis after prostate biopsies
    (Polish Urological Assoc, 2015) Yildirim, Mehmet Erol; Badem, Huseyin; Cavis, Mucahit; Karatas, Omer Faruk; Cimentepe, Ersin; Unal, Dogan; Incebay, Ilkay Bekir
    Introduction Transrectal ultrasonography (TRUS) guided prostate needle biopsy has been performed to diagnose and stage prostate cancer for many years. There are many different bowel preparation protocols to diminish the infectious complications, but there is no standardized consensus among urologists. Therefore, we aimed to assess two different bowel preparation methods on the rate of infectious complications in patients who underwent TRUS-guided prostate biopsy. Material and methods A total of 387 cases of TRUS-guided prostate biopsy were included in this retrospective study. All patients received antibiotic prophylaxis with ciprofloxacin (500 mg) twice a day orally for 7 days starting on the day before the biopsy. The patients were divided into two groups according to the bowel preparation method used. Patients (Group 1, n = 164) only received self-administrated phosphate enema) on the morning of the prostate biopsy. Other patients (Group 2, n = 223) received sennasoid a-b laxatives the night before the prostate biopsy. Infectious complications were classified as sepsis, fever (greater than 38 degrees C) without sepsis, and other clinical infections. Results Major complications developed in 14 cases (3.8%), including 3 cases (0.8%) of urinary retention, and 11 (3%) infectious complications, all of which were sepsis. There were 3 and 8 cases of urosepsis in Group 1 and Group 2, respectively. There were no statistically significant differences between both Groups regarding to the rates of urosepsis (p = 0.358). Conclusions Despite both methods of bowel preparation, sodium phosphate enema or sennasoid a-b calcium laxatives, before TRUS-guided prostate biopsy have similar effect on the rate of urosepsis, so both methods of bowel preparation can be safely used.

    The effects of thyroid hormones on uroflowmetry parameters in asymptomatic women
    (Tubitak Scientific & Technological Research Council Turkey, 2013) Cimentepe, Ersin; Yildirim, Mehmet Erol; Incebay, Ilkay Bekir; Carlioglu, Ayse; Karatas, Omer Faruk; Unal, Dogan
    Aim: To investigate whether there is any association between uroflowmetry parameters and blood levels of thyroid hormones in asymptomatic women. Materials and methods: Included in the study were 110 consecutive female patients with no urinary complaints who had thyroid function tests performed in an endocrinology clinic. Uroflowmetric measurements were performed for each patient in a sitting position. The patients were divided into 3 groups, hypo-, hyper-, and euthyroidism, and were investigated for statistical difference among them regarding maximum flow rate (Qmax), average flow rate (Qave), voided volume (VV), and voiding time (VT). Results: The mean Qmax and Qave values of hypo-, eu-, and hyperthyroid groups were 25.3 +/- 9.1 and 14.9 +/- 5.8, 28.6 +/- 9.6 and 16.2 +/- 6.4, and 21.5 +/- 8.7, and 13.2 +/- 5.6, respectively. In the evaluation of all groups, a statistically significant difference was found regarding Qmax (P = 0.004) and Qave (P = 0.024). When the groups were evaluated between each other, Qmax (p = 0.003) and Qave (P = 0.027) were significantly different between hyper- and euthyroid groups, with no statistically significant differences in other groups regarding the uroflowmetry parameters (P > 0.05). Conclusion: It has been found that Qmax and Qave were significantly lower in the hyperthyroid group as compared with the euthyroid group. According to these findings, it may be thought that hyperthyroidism negatively affects uroflowmetry parameters. To reach a definitive judgment, more investigations supported by urodynamic studies are necessary.
