Approach of the Clinicians Practicing in Intensive Care Units to Brain Death Diagnosis and Training Expectations in Turkey: A Web-Based Survey
(Elsevier Science inc, 2020) Ferhatoglu, Sibel Yilmaz; Ferhatoglu, Murat Ferhat; Gurkan, Alp; Genel Cerrahi / General Surgery
Background. For health professionals, recognizing and diagnosing brain death is vital for the development of organ transplantation. However, cadaveric organ donation rates remain insufficient, and this problem has become one of the most serious obstacles in the treatment of end-organ failure. Objectives. This study examines the attitude and knowledge level of clinicians who practice in intensive care units (ICUs) concerning the determination of brain death and describes the hindrances in diagnosing brain death. Materials and Methods. A survey study was designed with 26 questions, including questions regarding the determination of characteristics of respondents' trainings, prac-ticing preferences, and their knowledge and approach toward brain death diagnosis. Clinicians practicing in ICUs in Turkey were invited to the survey. Results. A total of 244 surveys were fully completed. Physicians working at the university hospitals or university-affiliated hospitals answered the basic knowledge questions about brain death more accurately (P < .001). Also, physicians employed in university or university-affiliated hospitals feel more capable in diagnosing brain death (P 1/4 .002) and are more willing to receive education on the brain death issue (P < .001). Conclusion. There is a gap separating the practices suggested in guidelines and the daily practice of ICU clinicians working in state hospitals or private institutions. Academic organizations producing and leading the education curricula may assist in informing ICU clinicians who should be trained.

Channels of being informed about kidney transplantation centers for patients with end stage kidney disease
(Aves, 2012) Gurkan, Alp; Gulhan, Yildirim B.; Tilif, Suleyman; Gul, Yeliz; Genel Cerrahi / General Surgery
Purpose: There are around 60,000 patients going through dialysis in our country. Although there are numerous successful transplant teams, the number of transplantations achieved has not reached the desired level. For this reason, kidney transplantation centers which keep increasing in number, have started different activities to inform these patients about the kidney transplantation. In our study, the patients having applied to three of the transplant centers in Istanbul were observed on how efficacious the activities were on the subjects. Patients and method: Patients having applied to the transplant centers in A (n: 1314), B (n: 27) and C (n: 229) hospitals, in the period between January 2, 2008 and December 31, 2010 were investigated by the organ transplant coordinators about how they were informed about these centers. In this study, it was observed that the patients got to know about the centers through dialysis centers stuffs, nephrologists, other patients, media and internet, etc. sources. We investigated on the differences these sources created in the different hospitals. In addition to these, on July 1, 2010; a website was established by A hospital with the same purpose. Also, the effect of this site in referring patients to the clinic was investigated. Results: We found out that patients were informed about organ transplantation centers from other patients, who have had organ transplantation (40.6%); dialysis centers (32.9%), media (9.6%), nephrologists (8.0%), internet (5.2%) and others (3.6%) (p=0.011). In A hospital, the mean average application number which was 34.6 patients/month went up to 44.5 patients/month after the establishment of the website. The website was found to be the only reason for the increase. Conclusion: Besides the mentioned factors; the internet which lately plays a great role in our daily life, also becomes an important guide for information for patients who want to have organ transplantation.

Clinicopathologic and Prognostic Features in Gallbladder Malignancies: Retrospective Analysis of 5206 Cases
(Galenos Yayincilik, 2019) Ferhatoglu, Murat Ferhat; Senol, Kazim; Kivilcim, Taner; Kartal, Abdulcabbar; Gurkan, Alp; Genel Cerrahi / General Surgery
Aim: Gallbladder cancer is the sixth most common cancer of the gastrointestinal system. Clinical presentation may not be distinguished from cholelithiasis or cholecystitis and most patients are diagnosed intraoperatively or in the postoperative histologic examination. In this study, we aimed to investigate the association of incidentally detected gallbladder cancer with gallbladder premalignant lesions, age, gender, ultrasonography features and gallbladder stones. Methods: Demographic and clinical characteristics and pathology results of 5206 patients who underwent cholecystectomy between January 2012 and December 2015 were evaluated retrospectively. Results: Three thousand eight hundred and eighty four (74.6%) patients were female. Pathologic reports showed pre-malignant and malignant lesions in 102 (1.95%) cases. Metaplasia was significantly more common in females, while no significant difference was found in development of dysplasia and cancer between genders. Gallbladder stone was found to be a risk factor for the development of metaplasia. Gallbladder wall thickening and advanced age are the most important risk factors for gallbladder cancer. Conclusion: Female gender and gallstone are important risk factors for the development of metaplasia. Advanced age, gallstone and gallbladder wall thickening on ultrasonography are the most important factors in the development cancer. Cholecystectomy should be kept in mind as the most effective method to prevent cancer development in elderly patients with gallbladder stones.

A Comparative Analysis of Once-daily and Twice-daily Formulation of Tacrolimus in De Novo Kidney Transplant Recipients
(Kare Publ, 2021) Ferhatoglu, Murat Ferhat; Kartal, Abdulcabbar; Kivilcim, Taner; Filiz, Ali Ilker; Yildiz, Gursel; Gurkan, Alp; Genel Cerrahi / General Surgery
Objectives: We aimed to compare the once-daily and twice-daily formulation of tacrolimus concerning the efficiency and effects on graft function in de novo kidney transplant patients. Methods: Twenty once-daily (TAC-OD) and twenty twice-daily (TAC-BID) tacrolimus administrated de novo kidney recipients who had received initial immunosuppressive therapy according to protocols at our institution (0.2 mg/kg of tacrolimus combined with 1000 milligrams of steroid taper plus 720 mg of mycophenolate and with 2.5mg/kg anti-thymocyte globulin) assessed concerning demographics, drug doses and blood concentration, and graft function. Results: The mean tacrolimus blood concentration measurements were higher in the TAC-OD group in the first sixty days after transplantation, and the TAC- OD group showed more blood concentration overshoots/fluctuations in the first 30 days of the treatment. The initial drug dose was significantly higher in the TAC-OD group than the TAC-BID group (p=0.04). There was no meaningful difference among groups according to graft function (creatinine measurements) (p>0.05). Conclusion: Between de novo kidney recipients, the new TAC-OD formulation presents a similar short-term efficacy profile as TACBID. However, a higher daily dosage of TAC-OD is needed to achieve similar blood concentrations in the early postoperative period.

Description and Outcomes of Three Different End-to-Side Microsurgical Techniques for the Anastomosis of Accessory Renal Artery With the Dominant Renal Artery in Kidney Transplantation
(Elsevier Science inc, 2021) Colak, Hulya; Kivilcim, Taner; Unverdi, Omer Faruk; Yildiz, Gursel; Gurkan, Alp; Genel Cerrahi / General Surgery
Background. In this study, we compared the outcomes of three different surgical microscope-assisted end-to-side anastomosis techniques between the dominant and accessory renal arteries during living donor kidney transplant. Methods. The demographics, serum creatinine levels, warm and cold ischemia times, rate of complications, and incidence of delayed graft function of 135 kidney recipients were analyzed according to the type of arterial anastomosis. Group A (n = 98) had one dominant renal artery (DRA) with one end-to-side anastomosis to the external iliac artery (EIA) using a surgical microscope. Group B (n = 17) had one DRA plus one accessory renal artery (ARA) with two separate end-to-side anastomoses to the EIA using a surgical microscope. Group C (n = 20) had one DRA with end-to-side anastomosis to the EIA and one ARA with an ex vivo on-bench end-to-side anastomosis to the DRA using a surgical microscope. Results. Compared with groups A and B, the cold ischemia time and the rate of delayed graft function were significantly higher in group C (P <= .001). At 6 months after transplant, group B demonstrated a higher creatinine value (2.40 +/- 3.41 mg/dL) than group A and group B (P = .032). Also, the decrease in creatinine at postoperative month 6 was limited in group B as compared with groups A and C. Conclusions. An end-to-side anastomosis between ARA (group B) and DRA (group A) of the kidney graft using a surgical microscope on the bench ex vivo results in superior outcomes. Single arterial anastomosis techniques are associated with a better function in a 6-month follow-up than two separate arterial anastomoses.

Effect of Visceral, Subcutaneous and Retroperitoneal Adipose Tissue on Renal Function After Living Donor Nephrectomy: A Retrospective Analysis of 69 Cases
(Urol & Nephrol Res Ctr-unrc, 2020) Ferhatoglu, Murat Ferhat; Atli, Eray; Gurkan, Alp; Genel Cerrahi / General Surgery
Purpose: Recent studies reported that the presence of metabolic syndrome is closely correlated with impaired kidney function after living donor nephrectomy. Since the measurement of body mass index cannot differentiate the amount of body adipose tissue from total body weight, body mass index is not a reliable parameter for determining metabolic syndrome. In the present study, we investigated the correlation between body adipose tissue and kidney function recovery following living donor nephrectomy. Materials and Methods: The patients who underwent living kidney donor nephrectomy consequently from July 2016 through December 2017 were enrolled in the study. We preoperatively measured the visceral (VAdT), retroperitoneal (RPAdT), and subcutaneous (SCAdT) adipose tissue volume by a computed tomography scan. Body mass index, adipose tissue measurements, and postoperative estimated glomerular filtration rate (eGFR) were evaluated. Results: The decrease between preoperative eGFR, and the first day, the first month and the sixth month eGFR after surgery were statistically significant (P = .001; P = .001; P = .001, respectively). The negative correlation between VAdT/SCAdT measurements and changes in eGFR at the first and the sixth postoperative month compared to preoperative eGFR were statistically significant (P = .049; P = .041, respectively). Additionally, RPAdT measurements and changes in eGFR at the first and the sixth postoperative month compared to preoperative eGFR (decreasing as RPAdT value increased) were statistically significant (P = .035; P = .026, respectively). Conclusion: According to a preoperative computed tomography scan, VAdT, RPAdT, and VAdT-to-SAdT ratio can predict impaired kidney function recovery. Furthermore, RPAdT measurement is a new variable to predict the impaired kidney function after living donor nephrectomy.

Evaluation of Male Circumcision: Retrospective Analysis of One Hundred and Ninety-eight Patients
(Springernature, 2019) Ferhatoglu, Murat F.; Kartal, Abdulcabbar; Gurkan, Alp; Genel Cerrahi / General Surgery
Introduction Circumcision is the oldest and most frequently used surgical procedure. It dates back to at least 10,000 years from today. The debate on the benefits and necessity of circumcision is ongoing. In this study, we aimed to determine the complications and complication rate of circumcisions occurring in our circumcision clinic and to compare these with the complication rates in the world. Methods A total of 198 male patients circumcised between 2011 at 2019 at Bursa State Hospital was enrolled in the presented retrospective study. Demographic data of the patients were assessed and the height and weight of the patients were evaluated according to the child growth standards and weight for age percentile charts for boys of the World Health Organization (WHO). All early or late complications were noted after circumcision. Results The mean age of the patients was 93.57 +/- 40.12 (2-248) months. The mean follow-up time was 16.32 +/- 9.24 (2-35) months. Sixteen patients had bleeding, four patients had a penile hematoma, and 108 patients had penile edema. There is no statistically significant difference in the penile edema occurrence according to the weight of the patients (p=0.58). Conclusion Circumcision is a frequently applied procedure. Like any other surgery, perioperative and postoperative complications can be observed. More importantly, a significant number of these complications can be prevented by careful surgery and postoperative care.

(2019) Murat Ferhat FERHATOĞLU; Ali İlker FİLİZ; Abut KEBUDİ; Abdülcabbar KARTAL; Alp GÜRKAN; Taner KIVILCIM; Gürsel YILDIZ; Genel Cerrahi / General Surgery
Aim: The aim of the study was to determine the prevalence and risk factors of bacterial urinary tract infection (UTI) in patientsundergoing renal transplantation and to evaluate the possible bacterial agents that colonize the bladder in patients with or withoutmicturition beforehand.Material and Methods: A total of 89 renal transplant patients were included in the study. Demographic characteristics of the patientssuch as age and gender, as well as the presence of micturition before transplantation, clinical findings, urine culture, and agents thatshowed growth were all retrospectively analyzed and the relevant data were recorded.Results: Of the total 89 patients, 17 (19.10%) developed a urinary tract infection within 12 months after transplantation. Eight ofthese patients required hospitalization for treatment, while four had at least two infection episodes. Escherichia coli and Klebsiellapneumonia were the two most common causative agents. A comparison of the groups with and without UTI revealed that micturitionbefore transplantation was not a factor that affected the development of UTI (p > 0.05).Conclusion: Because UTI represents a severe problem for renal transplant patients, it must be evaluated in all patients. No correlationwas found between preoperative micturition and postoperative UTI.

Evaluation of the Reliability, Utility, and Quality of the Information in Sleeve Gastrectomy Videos Shared on Open Access Video Sharing Platform YouTube
(Springer, 2019) Ferhatoglu, Murat Ferhat; Kartal, Abdulcabbar; Ekici, Ugur; Gurkan, Alp; Genel Cerrahi / General Surgery
Background The internet is a widely used source for obtaining medical information both by patients and physicians. YouTube (R) is a valuable information resource which can improve the learning experience of both public and medical professionals if appropriately used. In this study, we want to evaluate quality and accuracy of videos about sleeve gastrectomy procedure. Methods We included the first 100 videos returned by YouTube (R) search engine in response to "sleeve gastrectomy" keyword query to the study. The popularity of the videos was evaluated with an index called the video power index (VPI). Educational quality of videos was measured using the DISCERN score (DISCERN), Journal of American Medical Association (JAMAS) benchmark criteria, and Global Quality Scores (GQS). The technical quality was measured by Sleeve Gastrectomy Scoring System (SGSS) which was utilized by three bariatric surgeons. Results The source in 31% of the videos was a patient. The content in 53% of the videos was surgical technique. According to sources, videos uploaded by a university-affiliated physician had significantly higher DISCERN, JAMAS, GQS, and SGSS scores. Videos uploaded by a university-affiliated physician also had lower video power index than videos uploaded by patients. Surgical technique videos had significantly higher DISCERN, JAMAS, GQS, and SGSS scores. Patient experiences and advertisement videos had higher VPI scores. Also, negative correlations were found between video power index and JAMAS, GQS, and SGSS scores. Conclusions Online information on sleeve gastrectomy is of low quality, and its contents are of unknown source and accuracy. However, educational potential of YouTube (R) cannot be ignored.

(2019) Murat Ferhat FERHATOĞLU; Alp GÜRKAN; Taner KIVILCIM; Abdulcabbar KARTAL; Abut KEBUDİ; Ali İlker FİLİZ; Genel Cerrahi / General Surgery
Aim: In this study, we aimed to determine the approach of general surgeons toward laparoscopic inguinal hernia surgery and trainingneeds of surgeons and to collate data that will help formation of training programs or the development of current training programs.Material and Methods: A survey study was designed with 15 questions, including questions regarding determination of characteristicsof their trainings, surgical preferences, and their knowledge and approach toward laparoscopic inguinal hernia surgery. Generalsurgeons in Turkey invited to study on a voluntary basis by using Turkish Surgical Association’s official website.Results: A total of 160 surveys were completed included to the study. Of the total participants, 54.4% included laparoscopic herniasurgery in their daily applications. It was observed that most prevalently used surgical method (60.9%) was total extraperitonealapproach. Of 73 participants, 39 (52.8%) who did not include laparoscopic inguinal hernia surgery into daily surgical proceduresstated that they inform the patients about laparoscopic inguinal hernia surgery during the pre-operative evaluation. The rate ofperforming laparoscopic inguinal hernia surgery was found to be lower among those who had been working for ≥10 years (p = 0.001).Moreover, it was observed that only 18 (34.6%) of the 52 participants, who had been working for ≥10 years and who did not includelaparoscopic hernia repair into their daily surgical procedures, wanted to receive training.Conclusion: General surgeons have a difference of opinion on the benefits of laparoscopic inguinal hernia repair. It is necessary todetermine the obstacles for laparoscopic inguinal hernia surgery to be performed prevalently. Academic institutions designing andbringing the training programs into action can help inform surgeons who want and need the trainings, and success can be obtainedin shortening the time the learning curve takes and lowering of the recurrence and complication rates by continuous medical trainingprograms conducted routinely.

(Elsevier Science inc, 2022) Ferhatoglu, Murat Ferhat; Filiz, Ali Ilker; Sahin, Osman Z.; Gurkan, Alp; Genel Cerrahi / General Surgery
Background. Uncertainty raises questions in kidney transplant during the severe acute respira-tory syndrome coronavirus 2 (SARS-CoV-2) pandemic regarding the recipient, the donor, and health care professionals. The pandemic not only has disrupted kidney transplanted patients but also has influenced transplant systems, donation chains, and timely and safe transplant surgeries. In the present study, we aimed to explore the global effects of the SARS-CoV-2 pandemic on kidney transplant.Methods. We collected transplantation statistics and SARS-CoV-2 pandemic data from the World Health Organization website on June 15, 2021. Spearman correlation analysis was applied to assess the strength of a monotonic relationship among quantitative variables. We also demon-strated the clinical characteristics of our kidney recipients with SARS-CoV-2 infection.Results. Comparison of the mean of global kidney transplantation statistics between 2010 and 2019 with 2020 statistics showed a significant decrease in kidney transplant from living donors (P < .001). From the beginning of the pandemic to June 15, 2021, 1 of the 43 kidney transplant patients we treated in our clinic died of SARS-CoV-2 infection after discharge. Two of the patients we transplanted and saw in follow-up before the pandemic died of SARS-CoV-2 infection.Conclusion. While the overall kidney transplant numbers have increased in the year to date, kidney transplants decreased drastically at the onset of the pandemic.

The positive effects of preoperative chlorhexidine rinse to reduce postoperative pneumonia after kidney transplantation surgery
(Elsevier Ltd, 2024) Ferhatoglu,M.F.; Sahin,O.Z.; Kivilcim,T.; Gurkan,A.; Genel Cerrahi / General Surgery
Background: Postoperative pneumonia is one of the most observed hospital-acquired infections and increases the postoperative mortality rate. Further, it drives the healthcare systems under a severe financial burden. Preventing postoperative pneumonia is an incredibly challenging issue for clinicians. Since immunosuppression therapy, the patients who had kidney transplants are more vulnerable to postoperative infections. There is no data in the scientific literature focusing on the effects of preoperative oral care with chlorhexidine antiseptic solutions on postoperative pneumonia in kidney transplantation surgery cases. In the present research, we studied this topic. Methods: A prospective, randomized clinical trial was conducted at our institution between August 2020 and August 2022. Group A: Received 0.12 % chlorhexidine oral rinse preoperatively; Group B: Not received 0.12 % chlorhexidine oral rinse preoperatively. We analyzed the differences between the two trial groups using a chi-square or t-test. The Mann-Whitney U test was used for the categorical data. Results: Nine patients (17.6 %) were diagnosed with postoperative pneumonia in Group A and fourteen (25.9 %) in Group B (p < 0.05). Hospitalization time of Group B was prolonged (p < 0.05). In multivariate analysis, significant risk factors associated with postoperative pneumonia were advanced age, diabetes mellitus, smoking, delayed graft function and not gargling with 0.12 % chlorhexidine (p < 0.05). Conclusions: To reduce postoperative pneumonia risk in patients undergoing kidney transplantation surgery, an oral health protocol including 0.12 % chlorhexidine mouth rinse seems beneficial. © 2024 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland

(2024) Doğan, Demet; Gökce, Kağan; Kıvılcım, Taner; Gürkan, Alp; Genel Cerrahi / General Surgery
Amaç: Böbrek donör adayı olarak başvuran kişilere uygulanan Multidedektörlü Bilgisayarlı Tomografi Anjiyografi (MDBTA) incelemesinde; kişinin donör olmasını engelleyebilecek veya cerrahi yaklaşımın değişmesine neden olabilecek renal ve ekstra renal bulgularımızı bildirmeyi amaçlamaktayız. Nakil öncesi donör değerlendirmesi için yapılan MDBTA incelemesinin ve sonuçlarının transplantasyon planlaması üzerindeki etkisinin altını çizmeyi hedeflemekteyiz. Yöntem: Çalışmamızda Ocak 2017 ile Kasım 2022 tarihleri arasında 496 böbrek verici adayına uygulanan renal MDBTA tetkiki retrospektif olarak değerlendirdi. Her iki böbreğin boyutu ve parankim kalınlığı ölçüldü. Her iki taraf renal arter ve venin çapı, sayıları, varyasyonları, anomalileri tespit edildi. Renal ve diğer batın içi patolojiler belirlendi. Tüm bu değerlendirmelerin sonucunda böbrek nakline engel olan bulgular saptandı. Böbrek nakli için donör adaylarının preoperatif değerlendirilmesinde MDBTA bulguları ve bu bulguların cerrahi yaklaşımı ne oranda etkilediği belirlendi. Bulgular: 496 böbrek verici adayının 273’ü erkek, 223’ü kadın idi. Verici adaylarının yaş aralığı 20-85 arasındaydı, yaş ortalaması ise 46,25±13,2 idi. 278 tanesi donör adayı olmuş, 218 aday çeşitli nedenler ile elenmiştir. Bunların 22 tanesi MDBTA’de tespit edilen bulgulara bağlı olarak donör olamamıştır. Nakile engel olan en sık MDBTA bulgusu ise bilateral böbrek taşı idi. Sonuç: Renal transplant öncesi nakile engel olacak batın içi renal ve ekstrarenal patolojilerin değerlendirilmesi oldukça önemlidir. Renal MDBTA; canlı böbrek donörlerinin minimal invaziv, hızlı ve doğru bir şekilde değerlendirilmesini sağlar. Bu nedenle MDBTA renal transplantasyon öncesi değerlendirmede kullanımı gittikçe yaygınlaşan bir görüntüleme yöntemidir.

(Kare Publ, 2019) Ferhatoglu, Murat Ferhat; Kartal, Abdulcabbar; Kivilcim, Taner; Filiz, Ali Ilker; Kebudi, Abut; Gurkan, Alp; Genel Cerrahi / General Surgery
Objectives: The renal transplant program of Istanbul Okan University Hospital started in August 2017. Five cadaveric and 95 living donor kidney transplants have been performed for over 16 months. In this study, we aimed to share our experiences regarding kidney transplantation. Methods: In this study, a retrospective analysis of 100 patients who underwent kidney transplantation at the Istanbul Okan University over 16 months, the Health Application and Research Center was carried out. Patients' demographics, creatinine levels of donors and recipients, co-morbid conditions, postoperative complications, features of arterial anastomosis and arterial variations observed on computed tomography angiography of donor-patient were assessed. Results: Mean age of donor patients was 44.05 +/- 13.76 (18-71) years. All living donors had computed tomography angiography for assessment of the vascular structure of both kidneys. Accessory right kidney artery was the most dominant vascular variation (16.5%). The primary cause of chronic renal disease was diabetes mellitus (36.4%) and hypertension (15.6%). Mean warm and cold ischemia time was 1.82 +/- 0.44 (1-3) and 40.25 +/- 6.12 (31-57) minutes, respectively. The most observed postoperative complication was stenosis of ureter anastomosis (4.1%). End-to-end arterial anastomosis between renal and internal iliac arteries was the most preferred anastomosis (57.2%). Conclusion: Increasing kidney transplantation, which is the most appropriate treatment in terms of cost-effectiveness, will be beneficial for patient health and economy of the country.

Vascular variations of the kidney, retrospective analysis of computed tomography images of ninety-one laparoscopic donor nephrectomies, and comparison of computed tomography images with perioperative findings
(Via Medica, 2020) Ferhatoglu, M. F.; Atli, E.; Gurkan, A.; Kebudi, A.; Genel Cerrahi / General Surgery
Background: In this retrospective study, we aimed to determine the variations of kidney arteries and veins in kidney donor patients who underwent preoperative, computed tomography angiography (CTA). Materials and methods: We analysed kidney CTA findings of 91 donor nephrectomy patients operated from July 2016 through December 2017. Demographics, vascular diameters, abnormalities, numbers, branching variations, routing variations of arteries, and veins were assessed according to CTA images. We also compared the radiological findings with perioperative findings. Two radiologists evaluated CTA images, and the same surgical team performed all donor nephrectomies by laparoscopic approach. Results: Ninety-one of the 96 patients involved to study. Forty-six (50.5%) patients were female. Thirty-five (38.4%) of 91 cases had accessory arteries. Seven (7.6%) right, 1 (1.1%) left and 8 (8.7%) bilateral double hilar artery was observed on CTA. No statistically significant difference was observed in the evaluation of the side of accessory/polar arteries (p > 0.05), and in the evaluation of the distribution of arterial/venous variations according to perioperative findings (p > 0.05). However, in the evaluation of CTA images, we found that the diameter of the kidney artery and vein differed according to gender and side. Conclusions: The knowledge of the vascular variations of the kidney is essential for surgeons performing kidney transplantation. It is also essential for urologist and vascular surgeons. Incompatible with the literature, the right kidney has more vascular variations and, one kidney artery is found in the majority of Turkish kidney donor patients.
