    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 effectiveness of local steroid injection after internal urethrotomy to avoid recurrence
    (Pagepress Publ, 2015) Yildirim, Mehmet Erol; Kaynar, Mehmet; Ozyuvali, Ekrem; Badem, Huseyin; Cakmak, Muzaffer; Kosem, Bahadir; Cimentepe, Ersin
    Objective: Local steroid injection to the stricture region after internal urethrotomy (IU) is a promising technique to avoid the recurrence, although the effectiveness and safety of this technique is still controversial. We aimed to determine the efficacy and safety of local steroids as applied with the IU procedure. Material-Method: A total of 83 patients data with urethral stricture in men were examined retrospectively. Patients classified in two groups who had steroid injection with internal urethrotomy or not. Metil prednisolone 40 mg was injected with transurethral injection needle in the stricture region at the 5, 7 and 12 o'clock sites at the same session with internal urethrotomy. Procedure was considered successful if patient did not report any voiding difficulty and maximum flow rate > 15 mL/second for a voided volume of at least 150 mL after removal of the catheter. Patient's age, time to recurrence, previous recurrences were evaluated. Results: The mean age was 56.4 (18-83) years. Of those patients 33/83 had recurrent stenosis. Nineteen out of these 33 recurrent stenosis patients were treated with local steroid injection and 14/33 had no injection. Only two patients of the steroid treated group had recurrence. Despite that 12 patients had recurrence in the steroid non-treated group. Also the primary stenosis patients showed no recurrence at the steroid+ IU group. Conclusions: The use of local steroids with IU seems to decrease the high stricture recurrence rate following IU. When local steroids were administered with complementary intention, the disease control outcomes are encouraging. Further robust comparative effectiveness studies are now required.

    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.

    Urethral Caruncle Causing Bilateral Bladder Diverticula: A Case Report
    (Aves, 2016) Ozyuvali, Ekrem; Yildirim, Mehmet Erol; Kosem, Bahadir; Cimentepe, Ersin
    An urethral caruncle is a benign vascular tumor usually originating from the rear lip of the external urethral meatus and is usually observed in postmenopausal women. It is not included within the list of causes of bladder overdistension in women. We present a case of a urethral caruncle as a rare cause of acute urinary obstruction in a 71-year-old woman. The 71-year-old woman had occasional bleeding from a mass in the urethral meatus for 3 years. A reddish mass, measuring 3 cm in diameter, was noted at the posterior lip of the urethral meatus. The mass was diagnosed to be a urethral caruncle and was removed. Microscopically, the squamous epithelium, which covered the urethral caruncle, was found to be keratinized, with the proliferation of atypical cells with swollen nuclei in the entire mucosal layer. The patient could urinate better after the indwelling urethral catheter was taken out.

    What is harmful for male fertility: Cell phone or the wireless internet?
    (Wiley, 2015) Yildirim, Mehmet Erol; Kaynar, Mehmet; Badem, Huseyin; Cavis, Mucahit; Karatas, Omer Faruk; Cimentepe, Ersin
    In this study, we aimed to assess the potential harmful effects of radiofrequency-electromagnetic radiation on sperm parameters. We requested semen for analyses from the male patients coming to our infertility division and also asked them to fill out an anonymous questionnaire. We queried their mobile phone and wireless internet usage frequencies in order to determine their radiofrequency-electromagnetic radiation exposure. A total of 1082 patients filled the questionnaire but 51 of them were excluded from the study because of azoospermia. There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, (p = 0.074, p = 0.909, and p = 0.05, respectively). The total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage (p = 0.032 and p = 0.033, respectively). In line with the total motile sperm count, progressive motile sperm count also decreased with wireless internet usage compared with the wired internet connection usage (p = 0.009 and p = 0.018, respectively). There was a negative correlation between wireless internet usage duration and the total sperm count (r = -0.089, p = 0.039). We have also explored the negative effect of wireless internet use on sperm motility according to our preliminary results. Copyright (C) 2015, Kaohsiung Medical University.
