Nötrofil lenfosit oranı (NLR), trombosit lenfosit oranı (PLR) ve kırmızı hücre dağılım genişliği (RDW) inflamatuar hastalıklar ve kanserler için önemli bir belirteçtir. Çalışmamızda NLR, PLR, RDW’nin prostat biyopsi kararı almada belirleyici olup olmadığı değerlendirildi. 2017 Mayıs ile 2019 Aralık tarihleri arasında prostat spesifik antijen (PSA) yüksekliği olması veya prostat muayenesinde bulgular olması nedeniyle transrektal ultrasonografi (TRUS) eşliğinde prostat biyopsisi yapılan hastaların patoloji sonuçları ve labaratuvar değerleri retrospektif olarak incelendi. Kontrol grubu olarak prostatla ilgili şikayeti olmayan ve inflamatuar hastalık öyküsü ve kanser tanısı olmayan kişiler alındı. Biyopsi sonucu benign ve prostat kanseri (Pca) gelen hastalar ve kontrol grubu arasında NLR, PLR ve RDW açısından farklılık olup olmadığı incelendi. Biyopsi yapılan hastalar benign ve Pca olarak karşılaştırıldığında; prostat spesifik antijen (PSA) ve yaşın Pca grubunda istatistiksel olarak yüksek olduğu, hemoglobin değerinin ise düşük olduğu görüldü. NLR, PLR ve RDW açısından gruplar arasında farklılık olmadığı görüldü. Kontrol grubu ile Pca grubu karşılaştırıldığında NLR ve RDW değerlerinin Pca grubunda istatistiksel olarak daha yüksek olduğu görüldü. Prostat biyopsisi yapılan hastalarda Pca veya benign nedenlere bağlı inflamatuar bir durum mevcuttur. İnflamatuar belirteçler olan NLR, PLR ve RDW ‘nin prostat biyopsisi öncesinde Pca ve benign ayrımı açısından belirteç olarak kullanılamayacağı saptandı. Kontrol grubu ile Pca arasında olan farkın ise kansere bağlı meydana gelen inflamasyona bağlı olduğu düşünüldü. Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and red cell distribution width (RDW) are important markers for inflammatory diseases and cancers. In our study, it was evaluated whether NLR, PLR, RDW were determinative for prostate biopsy decision. The pathology results and laboratory values of the patients who underwent transrectal ultrasonography (TRUS)-guided prostate biopsy between May 2017 and December 2019 due to elevated prostate specific antigen (PSA) or findings in prostate examination were analyzed retrospectively. People who had no prostate-related complaints, cancer diagnosis and no history of inflammatory disease were included as the control group. It was investigated whether there was a difference in NLR, PLR and RDW between the patients with benign prostate cancer (Pca) biopsy and the control group. When the biopsy patients were compared as benign and PCa; Prostate specific antigen (PSA) and age were found to be statistically higher in the Pca group, while the hemoglobin value was lower. There was no difference between the groups in terms of NLR, PLR and RDW. When the control group and the Pca group were compared, it was observed that the NLR and RDW values were statistically higher in the Pca group. Patients who underwent prostate biopsy have an inflammatory condition due to PCa or benign causes. It was determined that NLR, PLR and RDW, which are inflammatory markers, cannot be used as markers for the differentiation of PCa and benign before prostate biopsy. The difference between the control group and PCa was thought to be due to cancer-related inflammation

Objective: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey. Material and methods: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period. An analysis was made of whether there was a difference in the number of radical prostatectomies performed for prostate cancer, the time from biopsy to operation, and the biopsy and radical prostatectomy pathology between the 2 periods. Results: It was found that the number of radical prostatectomies performed for localized prostate cancer during the coronavirus disease 2019 pandemic was statistically and highly significantly fewer than in the pre-coronavirus disease 2019 period (P < .001). The patients diagnosed with Gleason 3 + 3 (low risk) prostate cancer were statistically significantly fewer in number in the coronavirus disease 2019 period (P < .001). The pathological Gleason score was upgrading than the biopsy Gleason score in all patients who underwent in both periods (P < .001). When the periods were compared, the pathological involvement determined by lymph node dissection performed during radical prostatectomy was found to be decreased in the coronavirus disease 2019 period, although the difference was not statistically significant (P = .051). Conclusion: As with many diseases, the diagnosis and treatment of prostate cancer have been adversely affected by the coronavirus disease 2019 pandemic. © 2022, AVES. All rights reserved.

Objective: Coronavirus disease-2019 (COVID-19) pandemic changed various priorities in health area. Many elective surgeries for renal cell cancers (RCC) have been postponed. We examined the influence of the COVID-19 pandemic on the surgical treatment of RCC in Turkey. Materials and Methods: Surgically treated 457 patients for kidney tumor, from March 1, 2019 to February 28, 2021 in 9 centers in Turkey were analyzed retrospectively. Results: The number of surgical treatments for RCC during the COVID-19 pandemic has decreased significantly, in contrast to the same period before COVID-19. Admission symptoms were similar in these two periods (p=0.32). However, although not statistically significant, the rate of admission to hospital due to hematuria was higher during the pandemic period compared to the prepandemic period (14.4% vs 9.8%, respectively). The two study periods differed significantly in terms of the rate of metastatic RCC detected in preoperative imaging (13.1% vs 6.1%, during COVID-19 and pre-COVID-19, respectively) (p=0.01). Moreover, the study periods differed significantly in terms of time between imaging and operation [35 (2-240) vs 30 (1-210) days, during COVID-19 and pre-COVID-19, respectively] (p=0.01). However, these two periods were similar in terms of tumor size, type of surgery, and pathological stage (p≤0.05). Although the pathological stages were similar among the groups, nephrectomies due to the metastatic disease were significantly higher in the pandemic period (p=0.01). Conclusion: The number of RCC-related surgeries were significantly decreased during the pandemic period. However, the rate of surgery for metastatic disease has significantly increased.

ÖZETAmaç: Endoskopik üriner sistem taşı tedavisinde kullanılan irrigasyon sıvısı miktarının enfektif süreçlere etkisini araştırmak.Gereç ve Yöntemler: Çalışmaya, Ocak 2018 ile Ocak 2020 tarihleri arasında hastanemiz üroloji kliniğine üriner sistem taşı nedeniyle başvurmuş ve bu nedenle endoskopik litotripsi uygulanmış 77 hastanın verileri dahil edildi. İşlem sonrasında enfeksiyon gelişmeyen hastalar Grup 1, postoperatif enfeksiyon gelişen hastalar ise Grup 2 olarak kategorize edildi. Sonrasında bu iki grup arasında kullanılan irrigasyon sıvısı miktarı açısından fark olup olmadığı araştırıldı.Bulgular: Grup 1’de 45 hasta, Grup 2’de 32 hasta mevcuttu. İrrigasyon amaçlı kullanılan %0,9 NaCl sıvısı miktarı ortalama olarak 2142±1126,01 ml’dir. Kullanılan irrigasyon sıvısı miktarı postoperatif enfeksiyon gelişen grup için ortalama 2309,38±1220,4 ml, postoperatif enfeksiyon gözlenmeyen grup içinse ortalama 2023,3±1051,6 ml’dir ve her iki grup kullanılan irrigasyon sıvısının miktarı açısından karşılaştırıldığında anlamlı bir farklılık saptanmamıştır (p=0,275).Sonuç: Kullanılan irrigasyon sıvı miktarının bu süreçte önemli bir faktör olduğunu düşünsek de çalışmamız sonucunda anlamlı bir fark saptayamadık. Bu durum enfeksiyöz süreçlerde bir faktörün tek başına yol açmadığını diğer birçok etmenin bir araya gelip kümülatif bir etki yarattığı yönündedir.Anahtar Kelimeler: Üriner Taş Hastalığı; Lazer; Yıkama; EnfeksiyonABSTRACTObjective: To investigate the effect of irrigation fluid amount used in the treatment of endoscopic urinary tract stones on infective processes.Material and Methods: The data of 77 patients who applied to the urology clinic of our hospital between January 2018 and January 2020 due to urinary tract stones and therefore performed endoscopic lithotripsy were included in the study. Patients who did not develop infection after the procedure were categorized as Group 1 and patients who developed postoperative infection were classified as Group 2. Afterwards, it was investigated whether there is a difference in the amount of irrigation fluid used between these two groups.Results: Group 1 had 45 patients and Group 2 had 32. The amount of 0.9% NaCl fluid used for irrigation is 2142 ± 1126.01 ml on average. The average amount of irrigation fluid used was 2309.38 ± 1220.4 ml for the group developing postoperative infection, and 2023.3 ± 1051.6 ml for the group without postoperative infection, and no significant difference was found in terms of the amount of irrigation fluid used in both groups ( p = 0.275).Conclusion: Although we thought that the amount of irrigation fluid used was an important factor in this process, we could not detect a significant difference as a result of our study. This situation is that one factor does not cause alone in infectious processes and many other factors come together and create a cumulative effect.Keywords: Urinary Stone Disease; Laser; Irrigation; Infection

Elektronik destek sistemlerinde, elektronik harp ortamında bulunan tehdit radarların tespiti, ayrıştırılması ve kimliklendirilmesi işlemleri gerçekleştirilir. Elektronik destek sistemleri belirtilen işlemleri yerine getirebilmek için tespit edilen tehdit radar sinyallerinin karakteristik parametrelerini gerçek zamanlı olarak çıkarır. Tehdit radar sinyalinden çıkartılan parametrelerden bir tanesi tehdit yön bilgisidir. Tehdit yön bilgisinin radarın konumsal yerleşimi nedeni ile anlık olarak değiştirilememesi özellikle tehdit yoğun ortamlarda ayrıştırma işlemlerini kolaylaştırmaktadır. Bu nedenle tehdit yön bilgisinin yüksek doğrulukta tespit edilmesi elektronik destek sistemleri için kritik öneme sahiptir. Bu tez kapsamında elektronik destek sistemlerinde kullanılan tek darbe yön bulma algoritmaları analiz edilmiştir. Alan ve doğruluk parametreleri göz önüne alınarak önerilen optimum anten yerleşimi için hibrit yön bulma algoritması gerçek zamanlı olarak uygulanmıştır. Benzetim ortamında yapılan analizler sonucunda önerilen gerçek zamanlı algoritmanın 180 derece bakış açısında, en yüksek 0,24 derece RMS hata ile 188 nano saniye içinde tehdit yön tespiti gerçekleştirdiği gösterilmiştir. In electronic support systems; detection, separation and identification of threat radars in electronic warfare environment are performed. Electronic support systems obtain the characteristic parameters of the detected threat radar signals in real time to execute the specified tasks. One of the parameters achieved from the detected threat signal is the direction information of the threat. The threat direction information cannot be manupulated instantly due to the location of the radar. This facilitate threat separation especially in threat-intensive environment. Therefore, high accuracy detection of the threat direction information is critical for electronic support systems. In this thesis, monopulse direction finding algorithms used in electronic support systems are analyzed. Hybrid direction finding algorithm is applied in real time for the proposed optimum antenna placement considering the area and accuracy parameters. As a result of the analysis in simulation environment, it is shown that proposed real time algorithm provides threat direction finding in 188 nano seconds with the highest 0.24 degree RMS error in 180 degree angle of view. 82

Turizm ,Tourism - Abstract
Bu çalışmanın amacı, girişimcilikle ilgili temel kavramları ortaya koyduktan sonra, Giresun'daki turizm girişimciliği uygulamalarını değerlendirmek ve bir alan araştırması ile Giresun'daki turizm işletmelerinin mevcut durumu, olanakları ve paydaşların beklentilerini tespit etmektir. Bu çerçevede, tez üç bölümden oluşmuştur. Birinci bölümde, girişimcilikle ilgili temel kavramlar tanımlanmış ve bu kavramların turizm sektöründeki yeri belirlenmiştir. İkinci bölümde, Giresun'daki turizm işletmelerinin durumu, Giresun'da, turizm faaliyetleri ile ilgili olanaklar, Giresun'un doğal, tarihi ve kültürel değerleri ayrıntılı olarak ortaya konulmuştur. Tezin üçüncü bölümünde, Giresun'daki turizm işletmelerinin mevcut durumu, olanakları ve paydaş beklentileri konusundaki bir alan araştırmasının sonuçları verilmiştir. Tez çalışması, sonuç ve önerilerin ortaya konulmasıyla sona ermiştir. Alan araştırmasında, Giresun'da turizm sektörünün mevcut durumu bir GZTF (Güçlü yönler, zayıf yönler, tehditler ve fırsatlar) testi ve ilişkili bir anket formuna verilen yanıtların sıklık analizi çerçevesinde değerlendirilmesiyle elde edilen bulgularla ortaya konmuştur. Alan araştırmasının örneklemi, Giresun'u iyi tanıyan, kırk (40) kişiden oluşmuştur. Alan araştırması sonucunda elde edilen temel bulgu, Giresun İli'nin turizm sektörü açısından sunduğu yenilik olanakları, fırsatlar ve yüksek kazanç imkânları ile girişimcilik açısından uygun bir il olmasıdır. Diğer taraftan, Giresun İli özellikle, deniz turizmini ve yaylacılığı da içeren doğa turizmi açısından fırsatlar sunmaktadır. Bu alanların yanı sıra, inanç turizmi, tarih turizmi gibi bileşenleri de içeren kültürel turizm açısından Giresun İli yeniliklere açıktır. GZTF analizi çerçevesinde: Giresun İli'nin turizm sektörü açısından temel üstünlüğü sahip olduğu doğal ve tarihi varlıklardır. Bu çerçevede, İl'in temel zayıflıkları da altyapı yetersizliği, tanıtım ve lobicilik faaliyetlerinin eksikliği, farkındalık eksikliği ve özel sektör ilgisinin ve yatırımlarının azlığıdır. Giresun İli'nin önündeki başlıca fırsat, Karadeniz Bölgesi'nin yeni bir turizm destinasyonu olarak öne çıkmasıdır. Başlıca tehdit ise, bölge illeri arasındaki rekabet ve çevre kirliliğidir. Bu tez çalışmasında elde edilen diğer bulgular şunlardır: Giresun, kendine özgü coğrafi yapısı, kentsel ve kırsal yerleşim alanları, yaylaları, yayla göçleri, bir festivale dönüşen fındık hasat dönemi, sonbaharda gerçekleşen ve her yıl tekrarlanan büyükşehirlere göçleri, denizi ve buna özgü davranış şekilleriyle, kültürel açıdan çok zenginlik barındıran bir ildir. Karadeniz Bölgesi'nde yer alan Giresun İli, özellikle sıcak ve kurak ülkelerden gelen ve gelebilecek turistler için çok önemli bir uğrak noktası, `turizm destinasyonu` olabilir. Altyapı geliştirildiğinde, Giresun'a daha çok turist gelebilecektir; şehir ve çevresi daha cazip, daha çekici olabilecektir. Giresun'da mevcut durumda ya da sağlık hizmetlerinin daha da geliştirilmesiyle, sağlık turizmi faaliyetlerinin de yoğunlaşabileceği açıktır. Giresun'daki turizm işletmeleri, faaliyetlerinde, Giresun'un yöresel mutfağını, yöresel lezzetlerin daha çok öne çıkarmalıdırlar. Giresun, aynı zamanda, il olarak da güvenlik düzeyi yüksek olan bir ildir. Deniz ve karayolu ile ulaşım, yöresel güzelliklerin tadına varılarak seyahat etme imkânı sunmaktadır. Giresun ilini yerli ve yabancı turistler için çekici kılan en önemli unsurlardan biri de ilin sahip olduğu yaylalardır. Konaklama tesisleri, iç ve dış tasarım, sunulan hizmetler, çalışanların yetkinlikleri açılarından müşteri gereksinimlerini tatmin etmelidirler. Turistlerin misafirperver yerli halkla bütünleşmeleri teşvik edilmelidir. Bu çerçevede, Giresun'da da esnafın yardımsever olması ve işletme çalışanların nezaketi son derece olağan bir durumdur. Göreli olarak düşük ücret ve fiyatlarla, yöre, daha cazip kılınabilir. Giresun ili, farklı heyecanlar yaşamak, yeni dostluklar kurmak, sakin bir ortamda yaşamak, denizi, plajları, manzara ve doğal cazibe alanlarıyla yaşam sevincini hissetmek in son derece uygun bir yöredir. Giresun'un turizm alanında en önemli eksikliği hizmet kalitesi ve tesislerdir. The aim of this study is to put forward the basic terms about entrepreneurship, to evaluate the entrepreneurship activities in tourism sector in the Giresun province of Turkey, and to identify and evaluate the current conditions of tourism enterprises operating in this province, with a field research. The research also aims to learn the expectations of stakeholders. In this framework, the thesis includes three chapters. In the first chapter, the basic concepts about entrepreneurship and their situation in tourism sector is given. Then, in the second chapter, the conditions of Giresun's tourism enterprises, the probabilities of tourism in this province, the natural, historical and cultural values of this area are shown in details. The third chapter of the thesis includes an case study about the current conditions of tourism firms in Giresun province. This last chapter also includes evaluations about the probabilities of the sector, and the expectations of stakeholders. The thesis ends with a conclusion and several proposals.In the field research, the current situation of the tourism sector of Giresun province was evaluated with a SWOT (Strengths, weaknesses, opportunities, threats) analysis, and the frequency results of the answers of participants to a survey form. The sample consisted of forty (40) participants, who are knowledgeable about the province of Giresun. The basic finding after the field research is: Giresun is a suitable province for entrepreneurship, because it presents innovation, opportunities, and high income opportunities in tourism sector. On the other hand, Giresun province presents opportunities especially for nature tourism which includes sea tourism and plateau tourism. In addition to these areas, the province of Giresun is open to innovation for also the cultural tourism that includes elements as the tourism activities related with religious belief, or history based tourism. In the frame of SWOT analysis: the basic strength of Giresun province in the tourism sector is its natural and historical properties. Again, the basic weaknesses of the province are the insufficiency in infrastructure, advertisement and lobbying activities, awareness, and the insufficiency of private sector interests and investments. The major opportunity for Giresun province is, the rise of Black Sea region in tourism sector. Finally, the major threats are the competition between the neighbor provinces, and the environmental pollution. The other findings achieved in this study are the followings: The province of Giresun includes a cultural richness with its special geographical structure, urban and rural territories, plateaus, plateaus migrations, hazelnut harvest seasons, migrations to the large cities which is done in every autumn, and its sea and behavioral types special to the Black Sea culture. Giresun province, which is located in Black Sea region, can be a very important tourism destination point for especially tourist from hot and droughty countries. Accordingly, when the infrastructure is improved, the city and its environment will be more attractive, the number of incoming tourists will increase. Moreover, the health tourism activities can increase, due to the developments in health service infrastructure. The tourism firms of Giresun should put forward the local cuisine, local tastes among their services. On the other hand, the province of Giresun has a high security level. Again, there are many choices to reach Giresun. It can be reached by highway, airlines, or by ferries. The province of Giresun has many plateaus, which make the province more attractive for tourists. Accommodation opportunities, internal and external design, presented services, the competencies of employees should satisfy the customer needs. The integration of tourists with local people should be encouraged. In this framework, the kindness and helpfulness of business owners and their employees are important. The province can be made more attractive with lower prices. The province of Giresun is a very suitable province to live different excitements, to set up new friendships, to live in a restful environment. In addition, it has beautiful sea, seaside, beaches, landscape, and natural attraction areas which give the happiness of living. The most important weaknesses of Giresun are the quality of services, and facilities. 109

Gürel, A. Üriner sistem taş hastalığı ve klotho gen polimorfizmi arasındaki ilşikinin araştırılması. Eskişehir Osmangazi Üniversitesi Tıp Fakültesi Üroloji Anabilim Dalı Tıpta Uzmanlık Tezi, Eskişehir 2014. Üriner sistemde taş oluşumu; çevresel, anatomik ve genetik faktörlerin karşılıklı etkileşimine dayanan multifaktöryel bir olaydır. Epidemiyolojik çalışmalarda elde edilen veriler taş hastalığı prevalansının %3.5-18.5 arasında değiştiğini göstermiştir. Üriner sistem taş hastalığının (ÜSTH) en önemli özelliklerinden biri tekrarlama olasılığının fazla olmasıdır. Girişimsel tedavilerin maliyetinin yüksek olması, profilaktik tedaviye olan ilgiyi arttırmıştır. Taş hastalığının multifaktöryel doğası nedeniyle genetiğin katkısını tespit etmek zorluk arz etmektedir. Yapılan çalışmalarda yaşlanma karşıtı hormon (antiaging hormone) olarak bilinen Klotho geninin kalsiyum ve fosfor homeostazisinde son derece önemli rol oynadığı gösterilmiştir. Klotho, kalsiyum ve fosfor metabolizması üzerindeki etkisini B glukrodinaz aktivitesi ile göstermektedir. Yakın zamanda yapılan iki çalışma da klotho genindeki polimorfizmler ile üriner sistem taş hastalığı arasındaki ilişki bulunduğu saptanmıştır. Bu çalışmada üriner sistem taş hastalığı bulunan 103 hasta ve üriner sistemde taşı olmayan ve daha önceden taş öyküsü olmayan 102 kontrol grubu çalışmaya dahil edildi. Hasta ve kontrol grubu arasında yaş, cinsiyet açısından farklılık saptanmadı. Hasta ve kontrol grubu karşılaştırıldığında; hasta grupta yer alanların daha çok sedanter işlerde çalıştığı, beslenme şekli olarak daha çok hayvansal gıda ağırlıklı beslendikleri, vücut kitle indekslerinin daha yüksek değerlerde olduğu ve ailelerinde taş öyküsünün daha fazla görüldüğü sonucuna varıldı. Hasta grupta 24 saatlik idrar kalsiyum değeri kontrol grubuna göre yüksek saptandı. Hasta ve kontrol grubunda, klotho genindeki G395A, F352V ve C18118T polimorfizmleri karşılaştırıldığında hasta grupta G395A polimorfizmi, kontrol grubuna göre istatistiksel olarak anlamlı oranda fazla saptandı. Β glukrodinaz düzeyi karşılaştırıldığında; hasta ve kontrol grubunda istatistiksel olarak anlamlı farklılık saptanmadı. Anahtar Kelimeler: Üriner sistem taş hastalığı, klotho gen polimorfizmi, β glukrodinaz. Gürel, A. Investigation of the association between urinary system stone disease and klotho gene polymorphism. Eskişehir Osmangazi University School of Medicine Department of Urology Thesis in Medicine, Eskişehir 2014. Stone formation in urinary system is a multifactorial event which based on interaction among environmental, anatomical and genetic factors. Data from epidemiological studies showed that prevalence of stone disease varies between % 3.5 and 18.5. The most important feature of urinary system stone disease (USSD) is high recurrence possibility. Because of higher cost of interventional treatments, prophylactic treatment has been get considerable attention. It is difficult to identify the genetic contribution due to the multifactorial nature of stone disease. It was shown that Klotho gen which known as antiaging hormone has a critical role for calcium and phosphorus homeostasis. Klotho initiates own effect on calcium and phosphorus metabolism by the β-glucurodinase activity. In recent two studies, an association between klotho gene polymorphism and urinary system stone disease has been demonstrated. In this study, 103 patients with USSD and 102 controls without stone in urinary system or previous stone history were included. No difference was found between the patient and control groups for age and gender. When the patient and control groups were compared, it was concluded that cases from patient group work more sedentary occupations, feed with more foods of animal origin, have higher body mass index and more family history of stone. 24-hour urinary calcium level was higher in the patient group compared to control group. When G395A, F352V and C18118T polymorphisms in klotho gene were compared between groups, the ratio of G395A polymorphism was statistically higher in the patient group than control group. There was no statistical difference for β-glucurodinase between groups. Key Words: Urinary system stone disease, klotho gene polymorphism, β-glucurodinase. 77

Objectives: To investigate the effect of klotho gene and β-glucuronidase activity on stone formation in patients with urinary tract stone disease (UTSD). Methods: A total of 103 patients with UTSD and 102 controls with no specific urolithiasis history were enrolled into the study. G395A and C1818T polymorphisms of klotho gene were analyzed with PCR method. Serum levels of calcium and phosphorus and 24-h urine levels of β-glucuronidase activity, calcium and phosphorus levels were measured biochemically. Results: A total of 103 of patients were male (50.2 %) and 102 were female (49.8 %) ( p 0.945). Twenty-four-hour urine levels of calcium were significantly higher in UTSD group, whereas no difference was observed in phosphorus levels ( p < 0.001, p 0.074, respectively). As for the G395A polymorphism, type of GG was significantly higher in the patient group compared to the controls ( p = 0.02), while GA genotype was significantly higher in the controls ( p = 0.001). There was no significant difference in F352V and C1818T polymorphism between the patient and control groups. β-glucuronidase activity was slightly lower in the patient group without significance ( p 0.932).When patients with GG genotype and the rest were compared, there were no significant difference in all parameters. Conclusions: Any polymorphism altering the function of klotho gene may result with stone formation. We found that there are more GG sequences of G395A gene in patients with UTSD. That may be a polymorphism of klotho gene which results with stone formation. Further studies with more patients should be accomplished which are combining the genetic and epigenetic factors associated with urolithiasis and klotho gene to enlighten the etiology of this disease.

Objective: Coronavirus disease-2019 (COVID-19) pandemic changed various priorities in health area. Many elective surgeries for renal cell cancers (RCC) have been postponed. We examined the influence of the COVID-19 pandemic on the surgical treatment of RCC in Turkey. Materials and Methods: Surgically treated 457 patients for kidney tumor, from March 1, 2019 to February 28, 2021 in 9 centers in Turkey were analyzed retrospectively. Results: The number of surgical treatments for RCC during the COVID-19 pandemic has decreased significantly, in contrast to the same period before COVID-19. Admission symptoms were similar in these two periods (p=0.32). However, although not statistically significant, the rate of admission to hospital due to hematuria was higher during the pandemic period compared to the prepandemic period (14.4% vs 9.8%, respectively). The two study periods differed significantly in terms of the rate of metastatic RCC detected in preoperative imaging (13.1% vs 6.1%, during COVID-19 and pre-COVID-19, respectively) (p=0.01). Moreover, the study periods differed significantly in terms of time between imaging and operation [35 (2-240) vs 30 (1-210) days, during COVID-19 and pre-COVID-19, respectively] (p=0.01). However, these two periods were similar in terms of tumor size, type of surgery, and pathological stage (p≥0.05). Although the pathological stages were similar among the groups, nephrectomies due to the metastatic disease were significantly higher in the pandemic period (p=0.01). Conclusion: The number of RCC-related surgeries were significantly decreased during the pandemic period. However, the rate of surgery for metastatic disease has significantly increased.

Objective In this study, we aimed to determine if there was any relationship between patients with erectile dysfunction (ED) who do not seek medical help at the hospitals and their health literacy (HL) levels. Materials and methods The study included 68 patients. Patients with a main complaint of ED were included in Group 1, and those with benign prostatic hyperplasia (BPH) or who requested an age-related check-up were included in Group 2. Questions 1-5 and 15 of the International Index of Erectile Function (IIEF)-15 scale evaluating erectile functions were collected as IIEF-6 for the purpose of this study. Severe ED was defined as having a score of 0-10, while moderate ED was defined as a score of 11-16. Both patients with severe and moderate ED were considered and included in the study. The European Health Literacy Scale (HLS-EU) and the Turkey Health Literacy Scale-32 (THLS-32) were used for the evaluation of HL. Results The HLS-EU person-specific mean index was found to be 37.22 ±5.29 in Group 1 and 30.46 ±6.32 in Group 2. The THLS-32 person-specific mean index was determined to be 37.68 ±5.41 in Group 1 and 30.94 ±6.13 in Group 2. In Group 1, 58.3% of patients were classified as having sufficient HL and 22.2% were classified as having excellent HL. In Group 2, 21.9% of patients were classified as having sufficient HL and 3.1% were classified as having excellent HL. Conclusions As societal income, education levels, and HL levels increase, ED will become more important to individuals, motivating them to seek timely medical attention, and thereby leading to earlier diagnoses of potential primary pathologies.

Giriş: Üriner sistem taş hastalığı, görülme sıklığı iklim, etnik özellikler, genetik ve diyet alışkanlıklarına göre değişir. Taş hastalığı olanların ömür boyu en az bir kere olmak üzere nüks oranı yaklaşık % 50 olarak belirtilmiştir.Üriner sistem taş hastalığının değerlendirilmesinde kontrastsız BT altın standarttır. Taşın boyutu, hacmi, dansitesi gibi birçok özelliğini göstermede bize yardımcı olur.Üriner sistem taş hastalığı tedavisinde; ESWL, URS, RİRC, PNL, açık cerrahi ve laparoskopik cerrahi gibi yöntemler mevcuttur. Cerrahi yöntemin belirlenmesinde taşın boyutu, taşın hacmi, taş dansitesi, hastaya ait faktörler göz önünde bulunmalıdır. Tedavi yöntemleri belirlenirken cerrahi süre, skopi süresi, hastanede yatış süresi, olabilecek komplikasyonlar ve tedavi başarı oranı unutulmamalıdır. Holmium laser ile yapılan URS ve RİRC'de kısa süreli yatış, kısa cerrahi süre, kısa skopi süresi ve düşük komplikasyon nedeniyle tercih edilmektedir. Bu çalışmadaki amacımız; URS ve RİRC tedavisinin başarı oranın belirlemek için HU 'nun kullanılmasını göstemekti.Materyal ve Metod: Çalışmamızda 186 kadın, 380 erkek olmak üzere URS ve RİRC yapılan 566 hasta mevcuttu. Hastaların yaşı, cinsiyeti, taşın lateralitesi, preop ESWL öyküsü, preop DJ öyküsü, genitoüriner operasyon öyküsü, taş lokalizasyonu taş boyutu, taş dansitesi, taş hacmi, operasyon süresi, stone free olup olmaması verezidü taş boyutu kaydedildi.Elde edilen veriler, bilgisayar ortamında IBM-SPSS istatistik paket programı kullanılarak değerlendirildi.

- Abstract
Objective: This study is an investigation of the relationship between erectile dysfunction and epicardial adipose tissue and carotid intima-media thickness, which are indicators of endothelial dysfunction and subclinical atherosclerosis, in patients with newly diagnosed hypertension., Methods: The epicardial adipose tissue and carotid intima-media thickness of 101 male patients with newly diagnosed hypertension were measured using echocardiography between May 1, 2018 and May 31, 2019. Evaluation of erectile dysfunction was performed using the 5-item version of the International Index of Erectile Function (IIEF-5) in a face-to-face interview in the urology outpatient clinic. The data of patients with and without erectile dysfunction were compared., Results: There was a significant relationship between the presence and severity of erectile dysfunction and epicardial fat tissue and carotid intima-media thickness in patients with newly diagnosed hypertension. Left ventricular diastolic function was found to be more impaired in patients with erectile dysfunction., Conclusion: Erectile dysfunction was determined to be related to increased epicardial fat tissue and carotid intima-media thicknesses in patients with newly-diagnosed hypertension.
