Öğe The Effect of Double J Stents on the Sexual Life of Male Patients and Their Partners(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2019) Kaya, Coskun; Aykac, Aykut; Kaya, YelizObjective: In this study, it was aimed to show the changes in the sexual function of the male patients who underwent ureterorenoscopic (URS) and who had JJ stent (DJS) because of ureteral calculi and their spouses before and after the procedure. Methods: The male patients and their spouses who were admitted to the Urology Outpatient Clinic of Eskisehir State Hospital between May and August 2018 due to unilateral ureteral stones were included in the study. In order to determine sexual life, all of the male patients filled the International Index of Erectile Function (IIEF) form while their spouses filled the Female Sexual Function Index (FSFI) form. The patients with DJS and their spouses completed the forms just before the removal of DJS while the patients without DJS and their spouses filled the same forms 4 weeks after the procedure. The patients who were applied DJS after the operation of URS were defined as the study group, the patients who were not applied DJS after the operation of URS were defined as the control group. Results: Thirty one (34.4%) of 90 males who participated in the study were included in the study group. Fifty nine males (65.6%) without DJS included in the control group. There was no statistically significant difference between preoperational and post-operational scores of the male patients and their spouses on the scales of IIEF and FSFI, respectively (p>0.05). There was statistically significant decreases in the post-operational total and subscale scores of the male patients on the IIEF scale and the female patients on the FSFI scale compared to their total and subscale pre-operational scores (p<0.001). Conclusion: The male patients should be informed about their sexual life before endo-urologic procedures while their spouses should be informed about their sexual life after the procedure. DJSs should not be inserted except unavoidable circumstances; if they are inserted, they should be removed as soon as possible for minimizing their effects on the sexual lives of couples.Öğe The effect of modifiable lifestyle factors on semen quality(Elsevier Espana Slu, 2020) Kaya, Coskun; Aykac, Aykut; Kaya, Yeliz; Tas, MuratIntroduction and objectives: To examine the association between lifestyle factors (body mass index, smoking, alcohol consumption, coffee intake, physical activity, sauna and cell phone usage, wearing tight-fitting underwear), and conventional semen parameters. Materials and methods: 1311 participants who attended the Andrology Clinic were included in the study. All participants were separated into two groups as men with normozoospermia and dysspermia. All participants answered a questionnaire which contains questions about the modifiable lifestyle factors. The total risk scores were calculated after all the positive lifestyle factors had been counted. Results: Men with normozoospermia and dysspermia consisted of 852 (65.0%) and 459 (35.0%) participants respectively. A negative relationship between the wearing of tight underwear and having normal semen parameters was detected between the two groups (p=0.004). While going to a sauna regularly was negatively related to semen concentration, wearing tight underwear was also related to both lower motility, normal morphology as well as semen concentration (p < 0.05). While the total score of all participants was 5.22 +/- 1.34 point, there were no statistical differences between the two groups (p=0.332). It was found that having 3 more or fewer points was not related to any type of semen parameters and results of a spermiogram. Conclusion: The clinicians should give advice to infertile male patients about changing their risky lifestyle, for infertility, to a healthy lifestyle for fertility. Better designed studies, with larger sample sizes using conventional semen analysis with sperm DNA analysis methods, should be planned to identify the possible effects of lifestyle factors on semen quality.

Does common etiology cause togetherness?(2021) Baran, Özer; Aykaç, Aykut; Kaya, Coskun; Aktaş, HabibullahAim: We tried to determine the frequency of co-occurrence of erectile dysfunction (ED) and Onychomycosis (OM). Material and Methods: The sociodemographic form and IIEF-5 form were filled by the male patients who were admitted to the Urology Polyclinic of Karabük University Medical Faculty with the complaints of ED between April 2019 - April 2020. The patients with ED were included in the study. All the male patients were divided into three groups as mild, moderate and severe according to ED severity. The dermatologist (H.A) examined the presence of OM by taking samples from the toenails of the male patients. Results: Looking at the IIEF-5 scores of 95 patients accepted to the study, it was found that 22 (23.1%) had mild, 20 (21%) moderate and 53 (55.9%) severe ED. Smoking history was higher in the severe ED group (p <0.001). It was found that a total of 32 (33.7%) patients had OM. However, there was no relationship between the severity of ED and the presence of OM (p> 0.114). Conclusion: Erectile dysfunction and OM disease can often be seen together. However, no relationship was found with the severity of ED.Öğe The Predictive Role of Abdominal Fat Parameters and Stone Density on SWL Outcomes(Bentham Science Publ Ltd, 2020) Kaya, Coskun; Kaynak, Yurdaer; Karabag, Aral; Aykac, AykutBackground: Our aim was to detect the role of radiological abdominal fat parameters by tomography and stone density by plain X-ray on extracorporeal Shock Wave Lithotripsy (SWL) stone-free rate. Methods: The patients who had undergone SWL for a single opaque renal stone < 2 cm in diameter and proximal ureteric stone < 1 cm in diameter were collected retrospectively. The characteristics of patients and stones were recorded. The stone attitude, HU, abdominal fat parameters, paraperirenal fat area, perirenal infiltration and severity of hydronephrosis with pre-treatment Non-Contrast Computed Tomography (NCCT) and stone density with radiography were evaluated by a radiologist. Four weeks after the last SWL; all patients were evaluated by plain X-ray and categorized as Stone Free (SF) and Residual Fragment (RF) group. Results: 51 patients with renal stones and 88 patients with proximal ureteral stones were included in the study. 24 (47%) and 63 (71%) patients were classified as SF for renal and ureteral stones respectively. Only stone size was an independent predictor for stone-free rates after SWL for renal and proximal ureteral stones on multivariate analysis. The Receiver Operating Characteristic (ROC) curves for renal calculi revealed that creatinine level, stone size, stone attitude, Houns-Field Unit (HU) and Skin-to-Stone Distance (SSD) were the predictive factors for the SWL outcome (p<0.05). The ROC curve for ureteral calculi demonstrated that HU, stone size and attitude were the predictive factors (p<0.05). Conclusion: All abdominal fat parameters and the stone density were not related to SWL failure. A large follow-up with more patients is essential to confirm the role of radiological parameters on the outcome of SWL.Öğe Simultaneous Measurement of Pressure in the Calyces During RIRS in a Human Cadaver Model(Galenos Yayincilik, 2019) Aykac, Aykut; Baran, Ozer; Oner, Zulal; Kaya, Coskun; Ozok, Ugur; Sunay, MelihObjective: The aim of this study was to evaluate calyceal pressure caused by irrigation of the upper, mid and lower calyces in a cadaver kidney model and to examine the interactions. Materials and Methods: The kidney was dissected together with the ureter from a human cadaver from a 75-year-old without a history of renal disease. Catheters were placed in the bases of the calyces to perform pressure measurements. After recording baseline pressures while the flexible ureteroscope working channel was empty during irrigation, pressures were then measured by administering fluid with a hand pump, 5 cc and 50 cc syringe. Then, 272 mu and 350 mu laser probes were placed in the flexible ureteroscope and, after recording the baseline calyceal pressures, the measurements were repeated 3 times during hand pump irrigation. Results: Lowest calyceal pressures were measured when a 300 mu laser probe in the working channel of the flexible ureteroscope was placed in the upper calyx during irrigation at 60 cm H2O. Independent of the location of the flexible ureteroscope, the pressure in all the calyces was observed to be >= 50 mmHg during all types of fluid irrigation. All the calyceal pressures were observed to be affected by each other. The pressure within the calyx where the flexible ureteroscope was located was statistically significantly higher than in the other calyces (p<0.001). Conclusion: Application of additional fluid irrigation during flexible ureteroscopy causes a serious increase in intrarenal pressure. If fluid irrigation is to be applied, it should be done using a very small amount of fluid and for a very short duration.Öğe YouTube as a source of premature ejaculation(Elsevier Espana Slu, 2020) Kaynak, Yurdaer; Kaya, Coskun; Aykac, AykutIntroduction and objectives: To evaluate the quality of information in You Tube videos pertaining to premature ejaculation. Materials and methods: A search for premature ejaculation (PE) was performed on You Tube in August 2018. Two senior urologist viewers watched and categorized each video for their sources, suggestions and information contents (excellent, fair or poor). Results: Of the three hundred videos viewed on You Tube, 155 videos were included and analyzed. Mean video length (mean +/- standard deviation) was 3.08 +/- 2.02 min. The information content was excellent only in 17 (10.9%) of all videos while for a majority of them it was poor (57.4% n= 89). Fair videos constituted 31.7% (n =49) of the videos. There was no relation between the trustworthiness of the videos' contents and either their viewings or ratings (p= 0.561, p = 0.0966, respectively). Videos uploaded by health professionals were more reliable than those uploaded by laypersons (p < 0.001). Conclusions: The study suggests that although some videos, especially those uploaded by healthcare professionals, are useful; the majority of them have misleading information. Therefore, they are not a reliable source of PE information for patients. It is incumbent on urologists to counsel patients for other available useful internet information sources on PE.
