    • As far as we know, UPJO swine model has not been used for training. Zhang et al [7] reported the use of a healthy porcine animal model for laparoscopic pyeloplasty training by using a small intestine segment to simulate the enlarged renal pelvis. In our opinion, this model is perfect for enhancing intracorporeal suturing skills, whereas it is not as suitable as ours for dissection maneuvers, as it lacks fibrosis, adhesions, etc.
    [Show abstract] [Hide abstract] ABSTRACT: This study aims firstly to assess the most adequate surgical approach for the creation of an ureteropelvic juntion obstruction (UPJO) animal model, and secondly to validate this model for laparoscopic pyeloplasty training among urologists. Thirty six Large White pigs (28.29±5.48 Kg) were used. The left ureteropelvic junction was occluded by means of an endoclip. According to the surgical approach for model creation, pigs were randomized into: laparoscopic conventional surgery (LAP) or single port surgery (LSP). Each group was further divided into transperitoneal (+T) or retroperitoneal (+R) approach. Time needed for access, surgical field preparation, wound closure, and total surgical times were registered. Social behavior, tenderness to the touch and wound inflammation were evaluated in the early postoperative period. After ten days, all animals underwent an Anderson-Hynes pyeloplasty carried out by 9 urologists, who subsequently assessed the model by means of a subjective validation questionnaire. Total operative time was significantly greater in LSP+R (p=0.001). Tenderness to the touch was significantly increased in both retroperitoneal approaches, (p=0.0001). Surgeons rated the UPJO porcine model for training on laparoscopic pyeloplasty with high or very high scores, all above 4 on a 1-5 point Likert scale. Our UPJO animal model is useful for laparoscopic pyeloplasty training. The model created by retroperitoneal single port approach presented the best score in the subjective evaluation, whereas, as a whole, transabdominal laparoscopic approach was preferred.

    • This initial experience has been followed by others using the same approach or, alternatively , the retroperitoneal approach with the patient in the prone or in the lateral decubitus position [6, 7] and the transperitoneal approach with the patient supine [8]. Several reports have confirmed the safety and efficacy of these techniques, and minimally, invasive adrenalectomy is presently considered the treatment of choice for a variety of benign lesions, including lesions of the medulla [9, 10]. The aim of the present chapter is to report the authors' experience with left laparoscopic adrenalectomy (LA) using an original transperitoneal submesocolic and retropancreatic approach with patient supine, to describe the patient's preparation for surgery as well as the operative details of this procedure.
    [Show abstract] [Hide abstract] ABSTRACT: Introduction: The safety and efficacy of laparoscopic transperitoneal lateral adrenalec-tomy and retroperitoneoscopic adrenalectomy have been reported. The aim is to report the authors' experience in laparoscopic left adrenalectomy with an alternative trans-peritoneal submesocolic and retropancreatic approach with patient supine. Research methods: The authors have performed laparoscopic transperitoneal submesocolic, retropancreatic adrenalectomy for both benign and malignant, functioning lesions >4cm in diameter or with smaller lesions but having an imaging pattern suspicious of malig-nancy or of sub-clinically secreting tumors. After opening the posterior peritoneum at the root of the transverse mesocolon and Gerota's fascia, the junction of the inferior adrenal vein with the left renal vein is identified. The adrenal vein is then prepared and divided, followed by mobilization and removal of the left adrenal gland. Conclusion: Early ligation of the adrenal vein is the most relevant technical feature of this procedure to avoid the release of catecholamines, hormones or neoplastic cells which could occur during manipulation of the gland prior to ligation of the main adrenal vein. Moreover, this approach makes it possible to perform associated procedures , including a bilateral adrenalectomy, without the need to reposition the patient on the operative table, but simply by positioning additional trocars.

    • but not in black and white Americans [10]. Three case-control studies have observed that the A allele of E-cadherin C/A SNP confers higher risk for bladder cancer in the Chinese [53], Japanese [54], and Dutch [55] and is associated with invasive cancer [53]. Of particular note is a clinical outcome study following 302 patients with superficial bladder cancer after transurethral resection of the tumors for a median follow-up of 27.65 months [56].
    [Show abstract] [Hide abstract] ABSTRACT: Single nucleotide polymorphisms (SNPs) occurring in noncoding sequences have largely been ignored in genome-wide association studies (GWAS). Yet, amounting evidence suggests that many noncoding SNPs especially those that are in the vicinity of protein coding genes play important roles in shaping chromatin structure and regulate gene expression and, as such, are implicated in a wide variety of diseases. One of such regulatory SNPs (rSNPs) is the E-cadherin (CDH1) promoter -160C/A SNP (rs16260) which is known to affect E-cadherin promoter transcription by displacing transcription factor binding and has been extensively scrutinized for its association with several diseases especially malignancies. Findings from studying this SNP highlight important clinical relevance of rSNPs and justify their inclusion in future GWAS to identify novel disease causing SNPs.

    • There was no analysis of risk factors for conversions. Other smaller series reported complications in two patients (postoperative angina and contralateral atelectasis) of 19 patients who underwent LESS adrenalectomy [26].
    [Show abstract] [Hide abstract] ABSTRACT: Objective To comprehensively review current reports on the complications of laparoendoscopic single-site surgery (LESS), introduced recently into urology as an option for treating various urological pathologies.Methods We reviewed previous reports to August 2011 using Medline, focusing on LESS in urology, with special interest in the complications, evaluating those during and after surgery, as well as conversions to reduced-port laparoscopy, conventional laparoscopy and open surgery.ResultsThere are increasing reports of LESS in urology, with expanding indications. Complication rates both during and after surgery are low and related mostly to the technical difficulty and dexterity with the currently available instruments. Overall, intraoperative complications were reported by 11 published studies, while postoperative complications were reported by 15. Although the overall conversion rates to open surgery and conventional laparoscopy were low, the incidence of reduced-port laparoscopy was significantly higher.Conclusions Although there are expanding indications for LESS in urology, the risk of complications is low. This might be related to the fact that LESS is still restricted to experienced laparoscopic surgeons, and to the criteria for selecting patients.

    • For instance, Single-port LRP was preferred by Wen et al. [67] and has been shown to achieve better results in selected patients. Extraperitoneal LRP was preferred by Zheng et al. [66] for its advantages in preventing intra-abdominal complications and combined the advantages of minimally invasive laparoscopy and retropubic open prostatectomy. There are now several high-volume centers for RP with a well-designed follow-up system that makes the long-term assessment of the surgery result possible in developed countries such as Japan, Korea, Israel and developing countries such as China and India.
    [Show abstract] [Hide abstract] ABSTRACT: The incidence of prostate cancer (PCa) within Asian population used to be much lower than in the Western population; however, in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly. This collaborative report summarized the latest epidemiology information, risk factors, and racial differences in PCa diagnosis, current status and new trends in surgery management and novel agents for castration-resistant prostate cancer. We believe such information would be helpful in clinical decision making for urologists and oncologists, health-care ministries and medical researchers.

    • Adenomectomy is possible and entails no extra complications compared to total adrenalectomy [8,9] . Operative times are similar , although intraoperative blood loss is significantly greater in adenectomy, without, however, requiring supplementary trans- fusion [8,9]. The rationale supporting conservative surgery, however, is unclear in lateralized PA, which never shows recurrence in the contralateral adrenal; moreover, 10–25% of patients have several adjacent nodules, whether or not visible on preoperative imaging, and there is no way of knowing which is responsible for the PA, entailing a risk of incomplete treatment if part of the adrenal is spared [10].
    [Show abstract] [Hide abstract] ABSTRACT: Treatment of primary aldosteronism (PA) aims at preventing or correcting hypertension, hypokalemia and target organ damage. Patients with lateralized PA and candidates for surgery may be managed by laparoscopic adrenalectomy. Partial adrenalectomy and non-surgical ablation have no proven advantage over total adrenalectomy. Intraoperative morbidity and mortality are low in reference centers, and day-surgery is warranted in selected cases. Spironolactone administered during the weeks preceding surgery controls hypertension and hypokalemia and may prevent postoperative hypoaldosteronism. In most cases, surgery corrects hypokalemia, improves control of hypertension and reduces the burden of pharmacologic treatment; in about 40% of cases, it resolves hypertension. However, success in controlling hypertension and reversing target organ damage is comparable with mineralocorticoid receptor antagonists. Informed patient preference with regard to surgery is thus an important factor in therapeutic decision-making.

    • The ECM protein Fibulin-5, a transforming growth factor (TGF)-β-induced glycoprotein, is a multifunctional molecule that regulates various cellular processes, including proliferation, motility and invasion, in normal and malignant cells (Hu et al., 2011;Li et al., 2012;Xiao et al., 2013). Reduced expression of Fibulin-5 has been observed in a number of human cancers (Schiemann et al., 2002;Wlazlinski et al., 2007;Yanagisawa et al., 2009;Hu et al., 2011;Ohara et al., 2011). In this study, the expression of Fibulin-5 was detected in 86 glioma tissues and 20 NB tissues using immunohistochemical staining.
    [Show abstract] [Hide abstract] ABSTRACT: Fibulin-5 has recently been considered as a potential tumor suppressor in human cancers. Several studies have shown that it is down-regulated in a variety of tumor types and inhibits tumor growth and metastasis. This study was aimed to investigate the clinical significance of fibulin-5 in glioma and its role in cell proliferation and invasion. We found that the expression of fibulin-5 in glioma tissues was significantly lower than those in normal brain (NB) tissues. Negative expression was significantly correlated with advanced clinical stage (grade III+IV) . Furthermore, Fibulin-5 negative expression was correlated with a shorter overall survival of glioma patients. Multivariate Cox repression analysis indicated that fibulin-5 was an independent factor for predicting overall survival of glioma patients. Overexpression obviously inhibited cell proliferation in U251 and U87 cells. Furthermore, it significantly reduced the number of migrating and invading glioma cells. In conclusion, impaired expression of fibulin-5 is correlated with the advanced tumor stage in glioma. Otherwise, Fibulin-5 is an independent prognostic marker for predicting overall survival of glioma patients. Mechanistically, it may function as a tumor suppressor via inhibiting cell proliferation and invasion in gliomas.

    • NOTCH1 and DLL1 were most consistently diminished in both cell lines and tissues. Downregulation of these factors is in accord with a previous report [19], whereas another paper reported decreased NOTCH1 expression in high-grade invasive UC tissues only, with more pervasive cytoplasmic localization [28]. The mechanisms underlying these changes remain to be determined.
    [Show abstract] [Hide abstract] ABSTRACT: Background: Notch signalling regulates cell fate in most tissues, promoting precursor cell proliferation in some, but differentiation in others. Accordingly, downregulation or overactivity variously contributes to cancer development. So far, little is known about Notch pathway activity and function in the normal urothelium and in urothelial carcinoma (UC). We have therefore investigated expression of Notch pathway components in UC tissues and cell lines and studied the function of one receptor, NOTCH1, in detail. Methods: Expression of canonical Notch pathway components were studied in UC and normal bladder tissues by immunohistochemistry and quantitative RT-PCR and in UC cell lines and normal cultured urothelial cells by qRT-PCR, immunocytochemistry and Western blotting. Pathway activity was measured by reporter gene assays. Its influence on cell proliferation was investigated by γ-secretase inhibition. Effects of NOTCH1 restoration were followed by measuring cell cycle distribution, proliferation, clonogenicity and nuclear morphology. Results: NOTCH1 and its ligand, DLL1, were expressed at plasma membranes and in the cytoplasm of cells in the upper normal urothelium layer, but became downregulated in UC tissues, especially in high-stage tumours. In addition, the proteins were often delocalized intracellularly. According differences were observed in UC cell lines compared to normal urothelial cells. Canonical Notch pathway activity in reporter assays was repressed in UC cell lines compared to normal cells and a mammary carcinoma cell line, but was induced by transfected NOTCH1. Inhibitors of Notch signalling acting at the γ-secretase step did not affect UC cell proliferation at concentrations efficacious against a cell line with known Notch activity. Surprisingly, overexpression of NOTCH1 into UC cell lines did not significantly affect short-term cell proliferation, but induced nuclear abnormalities and diminished clonogenicity. Conclusion: Our data indicate that canonical Notch signalling is suppressed in urothelial carcinoma mainly through downregulation of NOTCH1. These findings can be explained by proposing that canonical Notch signalling may promote differentiation in the urothelium, like in many squamous epithelia, and its suppression may therefore be advantageous for tumour progression. As an important corollary, inhibition of canonical Notch signalling is unlikely to be efficacious and might be counter-productive in the treatment of urothelial carcinoma.

    • Their tendons are shaped as a tendinous arc in front of T12 (median arcuate ligament), and is crossed by the aortic artery and thoracic duct.8,12 The lateral pillars insert here and split into two robust tendons: one, the medial arcuate ligament (above the psoas muscle) bridging the L1 vertebra and the transverse apophysis,13 and the other, the lateral arcuate ligament (above the quadratus lumborum muscle) connecting the transverse process of L1 and the apex of the twelfth rib.14 The medial and lateral arcuate ligaments act as a bridge between the thoracolumbar fascia posteriorly and the transversalis fascia anteriorly.15–17
    [Show abstract] [Hide abstract] ABSTRACT: The article explains the scientific reasons for the diaphragm muscle being an important crossroads for information involving the entire body. The diaphragm muscle extends from the trigeminal system to the pelvic floor, passing from the thoracic diaphragm to the floor of the mouth. Like many structures in the human body, the diaphragm muscle has more than one function, and has links throughout the body, and provides the network necessary for breathing. To assess and treat this muscle effectively, it is necessary to be aware of its anatomic, fascial, and neurologic complexity in the control of breathing. The patient is never a symptom localized, but a system that adapts to a corporeal dysfunction.

    • Both retroperitoneoscopic (R‑LESS‑A) and transperitoneal (T‑LESS‑A) approaches to LESS‑A have been described, and different variations in the technique are practiced for each. Zhang et al. attempted 25 R‑LESS‑A using a TriPort (Advanced Surgical Concepts, Bray, Ireland) through a 2.5‑3 cm incision and two conventional instruments. [3] An additional 5 mm port was required in one patient and one patient required a conversion to LA. They noticed a reduction in the mean operative time from 62 minutes in the first 10 cases to 52 minutes in the subsequent 15. Chung et al. reported R‑LESS‑A in 7 patients using a glove‑port made with an Alexis wound retractor combined with s
    [Show abstract] [Hide abstract] ABSTRACT: Laparo-endoscopic single-site adrenalectomy (LESS-A) is commonly performed using specialized access devices and/or instruments. We report a LESS-A in a 47-year-old woman with a left aldosteranoma via a subcostal approach utilizing conventional laparoscopic ports and instruments. The feasibility and cost-effectiveness of this approach are highlighted and the literature on the subject is reviewed.

    [Show abstract] [Hide abstract] ABSTRACT: . Retrocaval ureter is a rare congenital anomaly. Open surgery was the classic treatment for this condition. Laparoscopy is currently an admitted procedure to treat many urological diseases. The objective of our study is to present our experience and discuss the safety and the feasibility of transperitoneal laparoscopic pyelopyelostomy for treatment of retrocaval ureter (RCU). Materials and Methods . Three symptomatic patients underwent laparoscopic repair for RCU in our department. The diagnosis was suspected on the computed tomography scan (CT) and confirmed on ascending pyelography. After placement of a JJ stent, and, using the transperitoneal approach, the retro peritoneum was exposed; the ureter was identified in both sides of the vena cava. The retrocaval segment was entirely mobilized and pulled from behind of the vena cava after section of renal pelvis. A pyelopyelostomy was done in a normal anatomic position. Results . All operations were achieved laparoscopically without conversion to open surgery. The mean operative time was 140 minutes (110–190). No intraoperative complication occurred. Blood loss was less than 50 mL in all patients. The mean hospital stay was 5 days (4–6 days). All patients were symptom-free after surgery and had reduction of hydronephrosis in control imagery. Conclusion . Laparoscopy seems safe, feasible, and reproducible in managing retrocaval ureter.
