    (Springer, 2021-11-26) Ünal, Ufuk; Çeçener, Gülşah; Ünlü, Havva Tezcan; Vuruşkan, Berna Aytaç; Erdem, Ecem Efendi; Egeli, Ünal; Nazlıoğlu, Hülya Öztürk; Kaygısız, Onur; Tunca, Berrin; Vuruşkan, Hakan; Ünal, Ufuk; ÇEÇENER, GÜLŞAH; Ünlü, Havva Tezcan; AYTAÇ VURUŞKAN, BERNA; Erdem, Ecem Efendi; EGELİ, ÜNAL; ÖZTÜRK NAZLIOĞLU, HÜLYA; KAYGISIZ, ONUR; TUNCA, BERRİN; VURUŞKAN, HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.; 0000-0003-4913-3616; 0000-0002-3820-424X; 0000-0002-0910-4258; 0000-0001-7904-883X; 0000-0002-9790-7295; 0000-0002-1619-6680; AAH-1420-2021; L-9439-2019; GYU-0252-2022; ABC-1357-2020; AAP-9988-2020; GYU-0252-2022; EEJ-1452-2022; ESY-2704-2022; FLN-9596-2022; ABI-6078-2020; EFH-9523-2022
    Background Clear cell type renal cell carcinoma (ccRCC) is the most common renal cell carcinoma (RCC). In this study, we examined the expressions of VHL and miR-223 in ccRCC patients' tissues to investigate the possible role in the development of ccRCC.Methods and results This study collected five expression profiles (GSE36139, GSE3, GSE73731, GSE40435, and GSE26032) from Gene Omnibus Data. Expressions of VHL and miR-223 in paraffinized tumor and normal tissues of 100 Turkish patients' ccRCC tissues were determined by bioinformatic data mining and real-time quantitative polymerase chain reaction (qRT-PCR). The VHL gene was subjected to mutational analysis by DNA sequencing, and pVHL was analyzed using western blotting. Our study's t-test and Pearson correlation analysis showed that VHL gene expression in tumoral tissues with a - 0.39-fold decrease was not significantly lower than normal tissues (p = 0.441), and a 0.97-fold increase miR-223 (p = 0.045) was determined by real-time PCR. Also, as a result of DNA sequence analysis performed in the VHL gene, it was found that 26% of the patients have mutations. The mutations for (VHL):c.60C>A (p.Val20=) and (VHL):c.467delA (p.Tyr156Leu) was detected for the first time in Turkish patients.Conclusions The present study demonstrated that the differences in the expression levels of miR-223 have the potential to be biomarkers to determine the poor prognosis in ccRCC.

    Challenging risk factors for right and left laparoscopic adrenalectomy: A single centre experience with 272 cases
    (Brazilian Soc Urol, 2019-07-01) Kordan, Yakup; Günseren, Kadir Ömür; GÜNSEREN, KADİR ÖMÜR; Çiçek, Mehmet Cağatay; ÇİÇEK, MEHMET ÇAĞATAY; Vuruşkan, Hakan; VURUŞKAN, HAKAN; Yavaşçaoğlu, İsmet; YAVAŞCAOĞLU, İSMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.; 0000-0001-8673-3093; 0000-0002-0471-5404; 0000-0002-9947-848X; ABC-9924-2020
    Purpose: This study aimed to compare perioperative and postoperative results of right and left laparoscopic adrenalectomy (LA), and to evaluate the impact of challenging factors on these outcomes.Materials and Methods: A total of 272 patient's medical records that underwent single side LA between October 2006 and September 2017 were retrospectively reviewed. The patients were divided into 2 groups according to operation side. Moreover, pheochromocytoma, metastatic masses and adrenal lesions >5cm in size were considered to be difficult adrenalectomy cases and the outcomes of these cases were compared between two groups.Results: 135 patients (49.6%) underwent right LA and 137 patients (50.4%) underwent left LA. Operation time, estimated blood loss (EBL) and hospitalization time were similar between the groups (p=0.415, p=0.242, p=0.741, respectively). Although EBL was higher on the right side than the left (p=0.038) in the first 20 cases, after this learning period has been completed, there was no significant difference between the groups. In patients with pheochromocytoma, metastatic mass and a mass >5cm in size, despite bleeding complications were clinically higher on the right side, this difference was not statistically significant.Conclusions: During the learning period of LA, EBL is higher on the right side. Due to the greater risk of bleeding complications on the right side even on the hands of experienced surgeons, extra care and preoperative planning are required in patients with pheochromocytoma, metastatic masses and masses >5cm in size.

    (Aves, 2020-07-01) Çiçek, Mehmet Çağatay; Kaynak, Yurdaer; Gunseren, Kadir Ömur; Kaygısız, Onur; Vuruşkan, Hakan; ÇİÇEK, MEHMET ÇAĞATAY; GÜNSEREN, KADİR ÖMÜR; KAYGISIZ, ONUR; VURUŞKAN, HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.; 0000-0002-0471-5404; 0000-0001-8673-3093; 0000-0002-9790-7295; ABC-9924-2020; L-9439-2019; HGM-5995-2022 ; EFH-9523-2022
    Objective: The aim of this study is to evaluate the effects of laparoscopic urologic surgery on cardiac functions by the parameter pulse wave velocity (PWV), a noninvasive method.Material and methods: Between July 2012 and February 2013, a total of 47 patients were included in this prospective controlled study. Patients who have been scheduled for laparoscopic surgery (LS) (n=30) and open surgery (n=17) were enrolled in the study. Preoperative, perioperative, and postoperative cardiovascular parameters were measured by a PWV instrument, and the results were compared between laparoscopic (L) group and open (C) group.Results: In the L group, compared to preoperative values, perioperative systolic arterial pressure, diastolic arterial pressure, and mean arterial pressure increased considerably, by 2.6%, 7.9%, and 4.7%, respectively. This was in contrary to reductions in these parameters by 9.5%, 5.7%, and 10%, respectively, in the C group. For the I. group, cardiac output (CO) and cardiac index (CI) were increased in the perioperative period and decreased in the postoperative period. For the C group, there were no changes in measurements of perioperative and postoperative CO and CI. However, these changes in CO and CI were not significantly different between the L and C groups. Postoperative large artery elasticity index decreased in both groups. However, these changes did not represent significant difference between groups.Conclusion: Compared to open surgery, LS may cause increases in perioperative blood pressures. In addition, increased blood pressures may last even on the first postoperative day. These effects may be more important for patients with high cardiovascular risk.

    (Wiley, 2021-06-12) Günseren, Kadir Ömur; Çiçek, Mehmet Çağatay; Bolat, Deniz; Yeni, Sezgin; Vuruşkan, Hakan; Gül, Özen Öz; Yavaşcaoğlu, İsmet; GÜNSEREN, KADİR ÖMÜR; ÇİÇEK, MEHMET ÇAĞATAY; VURUŞKAN, HAKAN; ÖZ GÜL, ÖZEN; YAVAŞCAOĞLU, İSMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Endokrinoloji ve Metabolizma Anabilim Dalı.; 0000-0001-8673-3093; 0000-0002-0471-5404; 0000-0002-1332-4165; ABC-9924-2020; HGM-5995-2022 ; GFT-1275-2022; EFH-9523-2022; GBT-4320-2022; EIN-0828-2022
    Objectives The study aimed to assess the haemodynamic changes of laparoscopic adrenalectomy (LA) in geriatric patients with pheochromocytoma (PHEO). To the best of our knowledge, this is the first study to evaluate the haemodynamic outcomes of LA in this patient population.Methods Data of 350 patients who underwent single-side transperitoneal LA between 2000 and 2020 were reviewed retrospectively. Patients with a histopathological diagnosis of PHEO were included in the study and classified into two groups according to their ages at the date of surgery. Patients older than 65 years were accepted as elderly according to the World Health Organisation (WHO) recommendations.Results A total of 54 patients underwent LA for PHEO. Fifteen patients were enrolled in the elderly and 39 in the young groups. There were no significant differences in terms of the operation site (0.564), tumour size (0.878), perioperative results such as mean anaesthesia; operation times, blood loss and haemodynamic changes. There were no significant differences in mean hospitalisation and intensive care unit times. One patient in both groups had grade 1 complication according to Clavien Dindo classification (prolonged ileus, managed with medical treatment and transfusion during surgery, respectively).Conclusion Young and elderly patients had similar outcomes in terms of haemodynamic changes that occurred with LA. LA in elderly patients with PHEO is as safe and effective as in younger patients.

    Single center experience with laparoscopic adrenalectomy on a large clinical series: Lessons learned from 273 cases: A retrospective cohort study
    (Kuwait Medical Association, 2022-12) Çelen, Sinan; Günseren, Kadir Ömur; Vuruşkan, Hakan; Acımış, Nurhan Meydan; Kordan, Yakup; Yavaşcaoğlu, İsmet; GÜNSEREN, KADİR ÖMÜR; VURUŞKAN, HAKAN; YAVAŞCAOĞLU, İSMET; Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Bölümü; ITO-9188-2023; EFH-9523-2022; EIN-0828-2022
    Objectives: We aim to evaluate the risk of laparoscopic adrenalectomy (LA) for large adrenal tumors and the risk of learning curve.Design: Single centre, retrospective studySetting: Uludag University, Bursa, TurkeySubjects: A study in a large patient population (N=273) who underwent LA between 2006 and 2017.Interventions: The patients were divided into two study groups according to tumour size as estimated by pathologic specimen maximum diameter, Group A (less than 5cm) and group B (larger than 5cm). In addition, to evaluate learning curve of LA, the patients were divided into two groups according to time interval: the first period was 2006 to 2011, and the second period 2012-2017.Main outcome measures: To evaluate the risk of learning curve and tumour sizeResults: There was no statistical difference between the two groups for per-operative and postoperative complications according to tumour size <5 or >= 5 cm, and there was statistical difference between the two groups for operation time, length of hospital stay; but no statistical difference for postoperative complications according to time interval.Conclusion: LA in large adrenal masses (5 cm or larger) is not associated with longer operative time, increased blood loss and longer hospital stay, without affecting perioperative morbidity, Hence, the size of an adrenal mass should not be the only factor in determining whether LA or not. Besides, learning curve may affect outcomes of LA.

    Objectives: To compare the effectiveness and complications of ureteroscopic laser lithotripsy with laparoscopic ureter laparoscopic ureterolithotomy in mid- or proximal portion of large ureteral stones. Material and Methods: We reviewed patients with large (>15 mm) ureteral stone and those who underwent ureteroscopic laser lithotripsy CURS group) or laparoscopic ureterolithotomy (LU group). The first attempt was considered successful in patients who had residual fragments smaller than 2 mm and no conversion of the primary procedure to another. Results: Sixty patients (URS group 29, LU group 31) met inclusion criteria. FURS was used as an adjunctive procedure in one patient for URS group and in two patients for LU group in the same season. LU had a higher success rate and the first-day stone-free rate when compared with URS. Number of procedures was also significantly higher in URS group. There was no difference in stone-free rates at the first and third months, and length of hospitalization and operation were higher in the LU group. Only two patients in the LU group and one patient in the URS group had major complications. Conclusions: Laparoscopy is an effective option of large proximal and mid-ureter stone treatment; however, URS provides similar stone-free rates at three months as a minimal invasive procedure.

    Background: Laparoscopic and robotic simple prostatectomy (SP) have been introduced with the aim of reducing the morbidity of the standard open technique. Objective: To report a large multi-institutional series of minimally invasive SP (MISP).Design, setting, and participants: Consecutive cases of MISP done for the treatment of bladder outlet obstruction (BOO) due to benign prostatic enlargement (BPE) between 2000 and 2014 at 23 participating institutions in the Americas and Europe were included in this retrospective analysis. Intervention: Laparoscopic or robotic SP.Outcome measurements and statistical analysis: Demographic data and main perioperative outcomes were gathered and analyzed. A multivariable analysis was conducted to identify factors associated with a favorable trifecta outcome, arbitrarily defined as a combination of the following postoperative events: International Prostate Symptom Score <8, maximum flow rate >15 ml/s, and no perioperative complications.Results and limitations: Overall, 1330 consecutive cases were analyzed, including 487 robotic (36.6%) and 843 laparoscopic (63.4%) SP cases. Median overall prostate volume was 100 ml (range: 89-128). Median estimated blood loss was 200 ml (range: 150-300). An intraoperative transfusion was required in 3.5% of cases, an intraoperative complication was recorded in 2.2% of cases, and the conversion rate was 3%. Median length of stay was 4 d (range: 3-5). On pathology, prostate cancer was found in 4% of cases. Overall postoperative complication rate was 10.6%, mostly of low grade. At a median follow-up of 12 mo, a significant improvement was observed for subjective and objective indicators of BOO. Trifecta outcome was not significantly influenced by the type of procedure (robotic vs laparoscopic; p = 0.136; odds ratio [OR]: 1.6; 95% confidence interval [CI], 0.8-2.9), whereas operative time (p = 0.01; OR: 0.9; 95% CI, 0.9-1.0) and estimated blood loss (p = 0.03; OR: 0.9; 95% CI, 0.9-1.0) were the only two significant factors. Retrospective study design, lack of a control arm, and limited follow-up represent major limitations of the present analysis.Conclusions: This study provides the largest outcome analysis reported for MISP for BOO/BPE. These findings confirm that SP can be safely and effectively performed in a minimally invasive fashion in a variety of healthcare settings in which specific surgical expertise and technology is available. MISP can be considered a viable surgical treatment in cases of large prostatic adenomas. The use of robotic technology for this indication can be considered in centers that have a robotic program in place for other urologic indications.Patient summary: Analysis of a large data set from multiple institutions shows that surgical removal of symptomatic large prostatic adenomas can be carried out with good outcomes by using robot-assisted laparoscopy.

    Estrogen receptors in prostate cancer (PCa) are a subject of debate. The aim of the present study was to investigate whether estrogen receptor-alpha (ER alpha) and estrogen receptor-beta (ER beta) impact the biochemical recurrence (BCR) of non-metastatic PCa after surgery. Following the application of the exclusion criteria, data from 108 patients who underwent laparoscopic radical prostatectomy between January 2011 and December 2019 were retrospectively evaluated. A total of 36 patients with BCR constituted the BCR group. The control group was formed using the Propensity Score Matching (PSM) method with a 1:2 ratio, including parameters with well-studied effects on BCR. The median follow-up time was 74.3 (range, 30-127.5) months in the BCR group and 66.6 (range, 31.5-130) months in the control group. Pathology specimens from the two groups were immunohistochemically stained with ER alpha and ER beta antibodies. Logistic regression analysis and survival analysis were performed. No differences in clinicopathological characteristics were detected between the two groups. The patients with ER alpha(-)/ER beta(+) staining results had a significantly fewer BCRs than other patients (P=0.024). In the logistic regression analysis, patients with ER alpha(-)/ER beta(+) PCa also had a significantly lower risk of recurrence (P=0.048). In the survival analysis, the 5-year BCR-free survival rate of patients with ER alpha(-)/ER beta(+) PCa was higher than that of other patients (85.7 vs. 66.1%; P=0.031). Excluding the effects of well-studied risk factors for recurrence by the PSM method, the present study showed that ER alpha and ER beta have prognostic value for non-metastatic PCa. The 5-year BCR-free survival rate is significantly higher in patients whose PCa tissue has ER alpha(-)/ER beta(+) staining results.

    Objectives: Lymphocele is a well-known postoperative surgical complication after kidney transplant. In this study, our aim was to analyze incidence, risk factors, and outcomes of posttransplant lymphocele in a large cohort.Materials and Methods: This observational study included 395 consecutive patients (219 males and 176 females) who underwent kidney transplant procedures from 183 living and 212 deceased donors in our center between January 2007 and 2014. A lymphocele was diagnosed with ultrasonography.Results: The incidence of lymphoceles in our cohort was 31.9% (n = 126). There were no significant differences with regard to body mass indexes, age of donors, deceased donor ratios, acute rejection episodes, and history of abdominal surgery between those with and without lymphoceles. The pretransplant serum albumin levels (3.29 +/- 0.67 vs 3.48 +/- 0.69 g/dL; P = .009) in the lymphocele group and diabetes mellitus ratios (15.9% vs 4.5%; P < .001) in the nonlymphocele group were lower than levels shown in the other group. The lymphocele ratio in patients who received cyclosporine was higher than that shown in patients who did not received it (37.5% vs. 27.4%; P = .032). There was no difference in lymphocele incidence between patients who were taking and those who were not taking mammalian target of rapamycin inhibitors, mycophenolate mofetil, or mycophenolate sodium. In regression analysis, presence of diabetes mellitus, transplant from deceased donors, older age of donors, and lower albumin levels were independent risk factors for posttransplant lymphocele occurrence.Conclusions: Posttransplant lymphocele was a relatively common surgical complication in our cohort. We concluded that diabetes mellitus, use of kidneys from deceased donors, older donor age, and hypoalbuminemia were independent risk factors for lymphocele development.
