Abstract
Introduction and importance Horseshoe kidney has unique anatomical features, such as a complex blood supply. We report a patient with renal tumor in a horseshoe kidney in close contact with the vena cava, who underwent open tumorectomy. Case presentation A 72-year-old woman was referred to our hospital with a 4-cm enhancing mid-pole mass in the right moiety of a horseshoe kidney. Open tumorectomy was performed with parenchymal clamping. The warm ischemia time was 18 min. Pathologic examination confirmed a diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins. At 3 months postoperatively, computed tomography showed no local recurrence or metastasis and renal function was intact. Clinical discussion Horseshoe kidney is a rare congenital abnormality. Renal cell carcinoma is the most frequent tumor in adults having this anomaly and treatment in localised tumors if usually tumorectomy. Surgery may be challenging in some cases because of its difficulty. Conclusion Open surgery remains the standard treatment for horseshoe kidney tumors because of anatomic complexity and especially in cases where the tumor is difficult to extirpate. Renal cell carcinoma tumors in horseshoe kidneys are a very rare entity. Management of localised tumors in horseshoe kidney is surgical and surgery is challenging due to anatomical difficulties. Open surgery is usually the best option for tumors having a posterior development in the horseshoe kidney.

Abstract
Introduction as COVID-19 pandemic is rapidly evolving, there is a whole reorganization in hospitals to concentrate more resources to face the crisis. The purpose of this study is to evaluate the impact of COVID-19 disease on urological activity in Tunisia. To assess the differences in the management of urological conditions between the private and the public field. Methods a survey was addressed to all certified urologists working in Tunisia in both the public and private sectors (n=194) using the national database of active urologists available and updated. We either called them or looked them up through email or social media. The form was open from March the 28th to April the 3rd. Results were obtained via spreadsheet and analysed using SPSS 23.0. Results one hundred and twenty urologists have filled in the form. Consultations at the outpatient office were restricted to urgent cases in 66% (n=79). Telemedicine was more used by urologists in private than in public fields p=0.03. Urologists in private sector followed more the sterilization protocol of the hospital/clinic and used more disposable materials whenever possible p=0.011. Elective surgical activity has completely stopped in 85% of the responders (n=102). Elective surgery requiring transfusion or intensive care unit was performed in 38% (n=46) and 26% (n=31) if there was a risk of disease progression. Benign Prostate Hyperplasia (BPH) surgery was more performed as usual in private sector than in public sector p=0.012. It was the only condition managed differently between both sectors. Conclusion the drop of the urological activity is essential in order to give relevant stakeholders room to act efficiently against the spread of the virus. The context of the pandemic and the hospital´s condition must be taken into consideration without compromising the patient´s outcome.

Abstract
Surgical procedures for benign prostate hyperplasia (BPH) had considerably evolved during last decades. New techniques can nowadays treat prostate big in size, which are classically treated by open prostatectomy (OP). Therefore, the place of this procedure that has been used for over 150 years is nowadays questioned. Is it outdated? Is there emerging techniques that are more efficient, safer and cost effective? This state of the art based on literature review will assess the place of OP in BPH surgery from efficacy on functional outcomes, security, competitiveness with modern and minimally invasive techniques and socio-economic perspectives. Currently, OP has excellent functional outcomes, with low rate of retreatment after surgery, low morbidity and affordable cost in our country. It remains competitive with new surgery techniques for BPH, even if the latter offer the advantages of a minimally invasive surgery, especially in hospitalization length. Taking in consideration the social and economic context in Tunisia, it remains the most accessible and affordable surgical technique. Besides, OP is a procedure that has to be handled by every urologist given the theoretical risk of conversion during endoscopic surgery of BPH, and its use under certain circumstances (In case of bladder lithiasis ou diverticle or impossibility of lithotomy position).

Abstract
PURPOSE To assess whether progressive and primary muscle invasive bladder cancer (MIBC) have different prognosis after radical cystectomy or not. To date only a few data are available on this topic with conflicting results. Further studies on large cohort are needed to clarify these outcomes that may influence bladder cancer management for these patients. MATERIAL AND METHODS A multicentre retrospective study was conducted on patient treated for MIBC at 5 centres between 2005 and 2015 by radical cystectomy. Patients' outcomes were compared between patients with primary MIBC vs. progressive MIBC subsequent to a history of non-muscle invasive bladder cancer (NMIBC). RESULTS A total of 1197 patients were included. Median (IQ) age was 65 (58-72) years and median follow-up was 65 months. Baseline characteristics were similar between the groups as well as the Tumour pT stage, N status and positive surgical margins. Patients with progressive MIBC had worse overall survival (OS) (hazard ratio [HR] 1.36, [95%CI 1.10-1.76]; P = 0.004), cancer specific survival (CSS) (HR 1.41 [1.13-1.78]; P = 0.002), and recurrence-free survival (RFS) (HR 1.21 [1.01-1.49]; P = 0.05). Pathological stage ≥pT3, positive surgical margins, and positive lymph nodes status (pN+) were also found as predictors of OS, CSS, and RFS. CONCLUSIONS Our results suggest that patient having a progressive BC have a worse prognosis in terms of OS, PFS, and CSS than patient with primary disease. These 2 groups may require different management and patients with high risk NMIBC should be assessed properly to avoid progression and be offered early cystectomy.

Abstract
BACKGROUND Given the high recurrence and progression rates and the absence of reliable markers for early detection and prognosis prediction of patients with urothelial bladder cancer (BCa), the exploration of new biomarkers with high specificity is imperative. Mainly, microRNAs (miRNAs), which are involved in the initiation and the progression of BCa. Herein, the expression patterns of miR-182, miR-205, miR-27a and miR-369 were evaluated in patients with urothelial BCa. METHODS AND RESULTS The expression levels of the miRNAs were investigated in 90 FFPE tissue samples (23 LG NMIBC, 44 HG NMIBC, 23 MIBC) and 10 non tumoral bladder tissues using TaqMan based RT-qPCR. Data analysis was performed using 2-ΔΔCT method. Correlation to clinical characteristics of the patients was performed using descriptive statistics and the receiver operating characteristic (ROC) curve was performed to evaluate the diagnostic value of all miRNAs. MiR-27a, miR-205 and miR-369 were down-regulated whereas miR-182 was up-regulated in patients compared to controls (p < 0.001). MiR-205 and miR-182 positively segregate between NMIBC and MIBC (p = 0.002 and p = 0.000 respectively) whereas the distribution of miR-27a's expression among these tumor groups was almost significant (p = 0.05) and that of miR-369's expression was irrelevant (p = 0.618). Interestingly, miR-182 was discriminative between LG NMIBC and HG NMIBC (p < 0.001) and Ta/T1 tumors (p = 0.000). Furthermore, high levels of miR-182 were potentially predictive of progression in NMIBC patients (p = 0.01). CONCLUSION Collectively, a selection of miRNAs was found to be aberrantly expressed in BCa suggesting a potential diagnostic value in BCa. In addition, the clinical value of miR-182 and miR-205 as potential prognosis biomarkers was highlighted. Indeed, our data provide additional insights into cancer biology. Further functional or target studies are mandatory to strengthen these findings.

Abstract
AIM OF THE STUDY The main difficulties during retroperitoneal laparoscopic adrenalectomies are due to its location. Our objective was to define the relationship of the adrenals with the diaphragm and the psoas muscle. METHODS Our work is an anatomical dissection of 80 fresh cadavers' adrenals. To study the right adrenal, we performed a right nephrectomy and adrenal remained attached to the Inferior vena cava by its main vein. On the left, the edges of the adrenal have been identified by needles and the adrenal was reclined to study its projection on the posterior muscular wall. RESULTS The right adrenal is located higher, 13mm [4-20mm] above the medial arcuate ligament (MAL) in 16 cases (40%). Its lower border was at the same level as the MAL in 18 cases (45%) and 11mm [10-17mm] below the MAL in 6 cases (15%). The posterior support of the right adrenal was the right crus of the diaphragm (Right-CD) in 34 cases (85%) and straddling the Right-CD and the psoas in 6 cases (15%). The study of the relationships of the left adrenal with the MAL showed that the lower edge of the gland was at its same level in 16 cases (40%) and below in 24 cases (60%) by 14mm [8-24mm]. The posterior support of the left adrenal was the left crus of the diaphragm (Left-CD) in 16 cases (40%) and straddling the Left-CD and the psoas in 24 cases (60%). CONCLUSIONS Our results showed that the right adrenal is higher. The MAL is an important posterior element to the adrenal gland that could serve as an anatomical landmark to identify the adrenal during laparoscopic adrenalectomy.

Abstract
To evaluate the efficacy of endoscopic meatotomy in the treatment of ureterocele in adults. A retrospective study of adult patients with ureterocele, treated between January 1987 and December 2014. In 47 patients, 55 intravesical ureteroceles were diagnosed and classified as 18 right, 21 left and eight bilateral (38%, 44% and 17% respectively). According to the Bruézière classification, 41 (75%) ureteroceles were type A and 14 (25%) others were type C. These ureteroceles were complicated by calculus formation in 22 cases, moderately dilated excretory pathways in 16 cases and both complications in a total of 9 cases. Four patients had a complicated ureterocele with pyelonephritis, one of which was emphysematous. The endoscopic treatment was performed in cases of complicated and/or symptomatic ureteroceles. Fifty one cases were treated by a “smiling mouth” meatotomy consisting in a transverse horizontal incision, with the treatment of any associated complication. The mean operative time was 35 minutes (10-90). The operative follow-up was uneventful in 42 patients and complications occurred in 5 patients (2 urinary retentions, 2 infectious complications and one hematuria). The mean duration of postoperative stay was 1-2 days. The mean follow-up was 15 months. Four patients developed vesicoureteral reflux and no stenosis was noted. The endoscopic incision of the ureteroceles seems today, after reviewing the results, to be a good treatment of adult ureterocele. It is a simple, minimally invasive and has a low morbidity rate.

Abstract
Multilocular cystadenoma are benign lesions located most commonly between the rectum and the bladder. Their presence manifests as obstructive or/and irritative lower urinary tract symptoms or transit disorders. Computed tomography scan and magnetic resonance imaging may help to establish the diagnosis. Surgery is the established treatment standard, with a high risk of recurrence in case of incomplete excision of the lesions. Here we report a case of 59-year-old man presenting with an acute urinary retention due to a giant multilocular prostatic cystadenoma treated by complete excision. The diagnosis has never been suspected before surgery and has been confirmed histologically after complete excision.

Abstract
To better understand the link between obesity and prostate cancer (PC) aggressiveness, we investigate the role of leptin, an obesity associated adipokine, and its receptor (Ob-R) in PC cells migration. The migration assay (Wound-healing) was used to study the leptin impact on DU-145 and PC3 cells lines. STAT3 activation was performed by Western Blot. E-cadherin expression was studied using fluorescence microscopy and Ob-R expression in PC and benign prostatic Hyperplasia (BPH) biopsies was assessed by RT-PCR. In this study we demonstrate that high dose of leptin promotes PC cells migration and EMT transition via the stimulation of STAT3 pathway. In addition, we report that although Ob-R mRNA is expressed by ADK and BPH resections biopsies, significant higher levels were observed for ADK patients. Finally, we found a positive association between Ob-R mRNA expression and worse PC prognosis. A better understanding of the molecular processes of leptin signaling is crucial for identifying appropriate approaches for treatment of obesity-related PC patients.

Abstract
BACKGROUND Stratification and risk-evaluation of bladder cancer (BCa) patients are far-reached issues, especially for those with non muscle invasive disease. Thus, setting-up biomarkers, especially after resection of the primary tumor, is crucial. Specifically, Neutrophil to lymphocyte ratio NLR and let-7 deregulation which have been preliminarily but not consistently described to be associated to unfavorable prognosis. OBJECTIVE To explore the clinical value of pre-treatment Neutrophil to Lymphocyte Ratio (NLR), let-7c and let-7g's deregulation. METHODS Data were extracted from ninety BCa samples. Pre-treatment NLR was estimated as the absolute neutrophil count divided by the absolute lymphocyte count. Expression patterns of let-7c and let-7g were assessed by qRT-PCR. Correlation with clinical characteristics was performed by descriptive statistics. RESULTS Both let-7 miRs were upregulated. Interestingly, let-7g was associated to pathological stage (p= 0.001) and tumor multiplicity (p= 0.003). NLR was associated to histological grade (p= 0.005) and clinical stage (p= 0.006). They were both associated to more aggressive phenotype and their worth as potential stratification biomarkers was confirmed by ROC curve. CONCLUSIONS Our data demonstrated the potential clinical value of all markers, especially pretreatment NLR and let-7g. Further studies are recommended to confirm their utility in improving the clinical decision-making regarding treatment and follow-up scheduling.

Abstract
INTRODUCTION The subdivision into two entities of papillary renal cell carcinoma (PRCC) was established on histological criteria. It's in fact possible to distinguish the two subtypes by the means of radiological and progressive data. The subtype 1 is associated with the favorable profile. The ultrasound and especially CT urography ensure an accurate diagnostic approach with substantial therapeutic and prognostic involvement. The aim of the study is to define the radiological features that distinguish the two subtypes of renal papillary carcinoma, and to study the radiological predictive factors of locoregional recurrence, metastases free survival and specific survival. METHODS It's about a monocentric, retrospective study led between January 2005 and June 2017, gathering 49 cases of operated PRCC. The study concerned patients over the age of 18, who were diagnosed after anatomopathological examination of the operative specimen (enlarged nephrectomy or conservative surgery). Cases in which diagnosis was made by renal biopsy were excluded. The comparative study concerned ultrasound and CT scan data. Univariate and multivariate analysis were performed to determine factors having a prognostic value in terms of locoregional recurrence, metastases-free and specific survival. RESULTS On the ultrasound, the subtype 1 tumors were significantly homogenous with regular contours. Tumors were globally spontaneously hypodense and hypo vascular in 97,8% of cases. Enhancement was significantly more heterogonous for subtype 2 (p=0,01). Intratumoral necrosis and adenomegalies were associated with subtype 2 (p=0,0001 and 0,005). The predictive factors of locoregional recurrence, metastases-free survival and specific survival in univariate analysis were the contours' aspect, moderate enhancement and the presence of adenomegalies. On multivariate analysis, only the irregular contours were retained for locoregional recurrence-free survival and specific survival. CONCLUSIONS Significant differences between the PRCC subtypes were observed when studying the radiological data. Irregular contours, adenomegalies and enhancement degree seemed to predict the progression of PRCC after curative surgery.
