Öğe Asymmetric dimethyl arginine levels in testicular tissue and blood of rats with induced experimental varicocele(Elsevier Espana Slu, 2014) Alan, Cabir; Ertung, Yunus; Cakir, Dilek Ulker; Topaloglu, Naci; Ersay, Ahmet Resit; Basturk, GokhanIntroduction: Varicocele is one of the reasons for testicular dysfunction and is frequently known to accompany infertility. The basic pathology of varicocele is the development of endothelial dysfunction. The most important factors in development of endothelial dysfunction are impaired endothelial-linked vasodilatation, increase in free oxygen radicals, reduced synthesis and release of nitric oxide (NO), abnormal vasoconstriction and increased levels of dimethyl arginine. Our aim was to identify and illustrate the relationship between asymmetric dimethyl arginine (ADMA) and NO levels in testicular tissue and plasma of rats with induced experimental varicocele. Materials and methods: Twenty-one adolescent (average 6 weeks) male rats were included in the study and randomly divided into 3 groups. Group 1 (control, n=6) did not undergo any procedure. Group 2 (sham, n=6) had the left renal vein circled proximally but ligation was not performed. Group 3 (varicocele-induced, n=9) had partial ligation of the proximal left renal vein to induce left varicocele. Superoxide dismutase (SOD) enzyme activity and levels of end-products of NO, nitrite and nitrate salts were investigated in testis tissue. Nitrite/nitrate and ADMA levels were investigated in plasma. Histopathological examination was completed with routine hematoxylin-eosine and TUNEL dyes. Results: Tissue SOD and plasma ADMA values were clearly increased in the varicocele group compared to the other groups; tissue and plasma nitrite/nitrate levels were clearly reduced in the varicocele group and this was observed to be statistically significant between the groups. Conclusion: We believe our study has opened an important window on the relationship between infertility observed in varicocele patients and ADMA. We believe that broad-series prospective studies to support this are required. (C) 2014 Asociacion Espanola de Andrologia, Medicina Sexual y Reproductiva. Published by Elsevier Espana, S.L.U.

Biofeedback in the treatment of dysfunctional voiding and urinary incontinence can be used. However, in the treatment of nocturnal enuresis is not included in the routine treatment options. We aimed to investigate the feasibility and effectiveness of biofeedback in the treatment of nocturnal enuresis. Material and Method: 50 children aged 5 years or older, who suffered a case of not wetting more than six-month period and admitted complaints of nocturnal urinary incontinence were included in the study. The mean age of patients was 9,4 +/- 2,52 (6-15). 27 patients (54%) were female and 23 patients (46%) were males. Biofeedback treatment performed to patients as 4 sessions. Each sessions were 30 minutes long every week. All patients were informed and advised to do the same exercise for 30 minutes every day at home. Results: Following the biofeedback treatment, incidence of wetting was found to have decreased significantly. 13% (3) of male patients and 11,1% (3) of female patients have not benefits from treatment. 87% (20) of male and 88,9% (24) of female patients have benefits from the treatment, frequency of urinary incontinence was reduced. Following the treatment, clinical improvement was 88%, while the rate of completely dryness was 54%. Statistical difference was found significantly at the incidence of wetting between before and after the treatment (p<0,05). Discussion: The positive results achieved in a short time indicates that the biofeedback method including the active participation of the child and the family in an environment of play, without medication, is candidate for the alternative treatment to nocturnal enuresis treatment.Öğe Diagnostic Value of Plasma Pentraxin3-Level For Diagnosis of Erectile Dysfunction(Urol & Nephrol Res Ctr-Unrc, 2018) Eren, Ali Erhan; Ersay, Ahmet Resit; Demirci, Emrah; Alan, Cabir; Basturk, GokhanPurpose: Erectile dysfunction (ED) is a sexual dysfunction described as the inability to develop or maintain an erection of the penis adequate for sexual intercourse, and its prevalence increases with age. Seen as a common sexual disorder worldwide, organic causes are the underlying reason for 80 percent of ED cases, with the most characteristic pathology responsible for organic ED being atherosclerosis. This study investigates the diagnostic value of plasma PTX-3 levels in arterial ED. Materials and Methods: This study included a total of 45 patients who were admitted to the urology and cardiology outpatient clinics of the Medical Faculty of Canakkale Onsekiz Mart University (COMU) and consented to participate in this study. Patients were categorized into three equal groups in number: (1) patients with ED diagnosed with coronary artery disease (CAD) (15 patients in total); (2) patients with ED not having coronary artery disease or any other equivalent diseases (diabetes mellitus, hypertension and hyperlipidemia) (15 patients in total); and (3) ordinary patients with no ED (15 patients in total). An interview was conducted at the andrology polyclinic with each patient in order to ascertain detailed information on their medical and sexual history and on demographic characteristics. All patients were also administered the International Index of Erectile Function (IIEF) questionnaire. Result: The findings from this study investigating the diagnostic value of plasma PTX-3 levels in ED were statistically significant for two comparisons: the differences between the peripheral blood and cavernous blood values of the patient groups (group 1 and 2) and the control group (group 3), and the differences between the peripheral blood and cavernous blood values of group 2 (patients with ED who do not have CAD) and the control group (group 3). Conclusion: As PTX-3 is more specific than the formerly recognized biochemical markers in endothelial dysfunction, it can be used in the diagnosis of vascular originated ED.Öğe Efficacy of duloxetine in the early management of urinary continence after radical prostatectomy(S. Karger AG, 2014) Alan, Cabir; Eren, Ali E.; Ersay, Ahmet R.; Kocoglu, Hasan; Basturk, Gokhan; Demirci, EmrahAim: To evaluate the efficacy of early duloxetine therapy in stress urinary incontinence occurring after radical prostatectomy (RP). Material and Method: Patients that had RP were randomly divided into 2 groups following the removal of the urinary catheter. Group A patients (n = 28) had pelvic floor exercise and duloxetine therapy. Group B patients (n = 30) had only pelvic floor exercise. The incontinence status of the patients and number of pads were recorded and 1-hour pad test and Turkish validation of International Consultation on Incontinence Questionnaire-Short Form test were applied to the patients at the follow-up. Results: When the dry state of the patients was evaluated, 5, 17, 3, and 2 of 28 Group A patients stated that they were completely dry in the 3rd, 6th, 9th and 12th month respectively and pad use was stopped. There was no continence in 30 Group B in the first 3 months. Twelve, 6, and 8 patients stated that they were completely dry in the 6th, 9th and 12th month, respectively. But 3 of 4 patients in whom dryness could not be provided were using a mean of 7.6 pads in the first day and a mean of 1.3 pads after 1 year. When pad use of the patients was evaluated, the mean monthly number of pad use was determined to be 6.2 (4-8) in the initial evaluation, 2.7 (0-5) in the in 3rd month, 2 (0-3) in the 6th month and 1.6 (0-2) pad/d in the 9th month in the group taking medicine. The mean monthly number of pads used was determined to be 5.8 (4-8) in the initial evaluation, 4.3 (3-8) in the 3rd month, 3 (0-6) in the 6th month and 1.6 (0-6) pad/d in the 9th month in the group not taking medicine. Conclusion: According to the results, early duloxetine therapy in stress urinary incontinence that occurred after RP provided early continence. © 2014 S.

Material and Methods: The study included 21 adolescent (average age 6 weeks) Sprague-Dawley male rats weighing between 240-290g divided at random into 3 groups. Group-1: Control group (n= 6): underwent no procedures. Group-2: Sham group ( n= 6): underwent the same procedures as the experimental group without ureter and psoas muscle dissection. Group-3: Group with induced partial unilateral ureteral obstruction (n= 9). All rats were sacrificed after 12 weeks. Superoxide dismutase enzyme activity and nitrite and nitrate salt levels were measured in renal tissue. Plasma nitrite-nitrate and ADMA levels were examined. Results: In the experimental group histopathological changes observed included renal pelvis dilatation, flattened papillae, sclerotic glomerulus and fibrosis. In the experimental group tissue SOD and blood ADMA levels were higher than the control and sham groups (p< 0.05) while tissue NO and plasma NO values were lower than in the sham and control groups (p< 0.05). Conclusion: Oxidative stress and disruption of NO synthesis play an important role in renal function and histopathological changes after obstructive renal disease. To prevent renal complications developing after obstructive nephropathy we believe that a new strategy may be research on reducing ADMA.
