RESUMEN
INTRODUCTION: Physical examination appears to be a limiting factor of teleconsultation (TC). We evaluated the feasibility of self-percussion of the lumbar fossae (sPLF) and TC for simple renal colic (SRC) in comparison with a face-to-face consultation (FC). MATERIAL AND METHODS: We performed a comparative prospective study in two steps. First: evaluation of the quality of an sPLF on a standardized patient in TC, without and with tutorial. Secondarily: evaluation of a TC and a FC for a SRC with a standardized patient in real conditions. Evaluation using objective clinical scores and qualitative scales by an observer, the standardized patient and the practitioner himself. RESULTS: Forty-two practitioners were included in the study. In the absence of a tutorial, the sPLF was most often "poorly done". The tutorial led to a significant improvement in the quality of sPLF. There was no difference in diagnostic and therapeutic performance among senior physicians between TC and FC. The therapeutic performances of the interns were significantly lower in TC without his being aware of it. The qualitative scores were significantly lower in TC vs FC according to the practitioners, the standardized patient and the observer. CONCLUSION: An sPLF is feasible but its practice should be taught. Unlike interns, senior physicians were able to perform a TC comparable to FC for the management of SRC. TC and telesemiology therefore require dedicated training and an experienced practitioner.

INTRODUCTION: Almost half of the patients have had recurrent nephrolithiasis despite undergoing effective treatment. Our objective is to determine the recurrence rate of lithiasis after endourological management of nephrolithiasis and identify the risk factors for these recurrences. METHODS: Data were gathered retrospectively from all patients who were treated for nephrolithiasis by endourological management from May 2014 to January 2017 in our university hospital. The patients were devised into two groups: with and without recurrence. Many variables were also compared between these two groups. RESULTS: During this period 265 patients were treated for upper urinary tract stone. A total of 190 patients were included in the study. The median age and median BMI of the patients were 57.5 years and 25.2kg/m2, respectively. A biochemical analysis of the stones was performed in 117 (61.5%) patients. The most common types of stones were calcium oxalate monohydrate stones (n=44, 23.2%), mixed stones (n=39, 20.5%) including mixed calcium oxalate (n=10; 8.5%), calcium oxalate dihydrate stones (n=13, 6.8%) and uric acid stones (n=11, 5.8%). At the end of a median follow-up of 32 months (range, 13-61 monthes), 49 patients (25.8%) had a recurrent stone. In univariate analysis, the risk factors for recurrence were BMI greater than 25kg/m2 (HR: 2; P<0.05), diabetes (HR: 3.73; P<0.008) and smoking (HR: 3.1; P<0.039). However age (HR: 0.96: P<0.003) and high blood pressure (HR: 0.37; P<0.027) were protective factors. In multivariate analysis, diabetes, smoking, hypertension, and age are still risk factors for recurrence. CONCLUSION: Stone recurrence is common after the management of urinary stones. In this study 25.8% of patients had recurred stone disease after endourological management with a median follow-up of 32 months. Our study findings showed that diabetes and smoking are risk factors for recurrence, while age and blood hypertension are protective factors that decreased the risk of recurrence.

AIM: To update the recommendations for the management of kidney cancers. METHODS: A systematic review of the literature was conducted from 2015 to 2022. The most relevant articles on the diagnosis, classification, surgical treatment, medical treatment and follow-up of kidney cancer were selected and incorporated into the recommendations. Therefore, the recommendations were updated while specifying the level of evidence (high or low). RESULTS: The gold standard for the diagnosis and evaluation of kidney cancer is contrast-enhanced chest and abdominal CT. MRI and contrast-enhanced ultrasound are indicated in special cases. Percutaneous biopsy is recommended in situations where the results will influence the therapeutic decision. Renal tumours should be classified according to the pTNM 2017 classification, the WHO 2022 classification and the ISUP nucleolar grade. Metastatic kidney cancer should be classified according to the IMDC criteria. Partial nephrectomy is the gold standard treatment for T1a tumours and can be performed by an open approach, by laparoscopy or by robot-guidance. Active surveillance of tumours less than 2cm in size can be considered regardless of the patient's age. Ablative therapies and active surveillance are options in elderly patients with comorbidity. T1b tumours should be treated by partial or radical nephrectomy depending on the complexity of the tumour. Radical nephrectomy is the first-line treatment for locally advanced cancers. Adjuvant treatment with pembrolizumab should be considered in patients at intermediate and high risk for recurrence after nephrectomy. In metastatic patients: Immediate cytoreductive nephrectomy may be offered to oligometastatic patients in combination with local treatment of metastases if this can be complete and delayed cytoreductive nephrectomy can be proposed for patients with a complete response or a significant partial response. Medical treatment should be proposed as first-line therapy for patients with a poor or intermediate prognosis. Surgical or local treatment of metastases can be proposed in case of single or oligo-metastases. The recommended first-line drugs for metastatic patients with clear cell renal carcinoma are the combinations axitinib/pembrolizumab, nivolumab/ipililumab, nivolumab/cabozantinib and lenvatinib/pembrolizumab. Cabozantinib is the recommended first-line treatment for patients with metastatic papillary carcinoma. Cystic tumours should be classified according to the Bosniak classification. Surgical removal should be proposed as a priority for Bosniak III and IV lesions. It is recommended that patient monitoring be adapted to the aggressiveness of the tumour. CONCLUSION: These updated recommendations are a reference that will allow French and French-speaking practitioners to improve kidney cancer management.

OBJECTIVE: To propose recommendations for the management of renal cell carcinomas (RCC) of the renal transplant. METHOD: Following a systematic approach, a review of the literature (Medline) was conducted by the CTAFU to evaluate prevalence, diagnosis and management of RCC arousing in the renal transplant. References were assessed according to a predefined process to propose recommendations with levels of evidence. RESULTS: Renal cell carcinomas of the renal transplant affect approximately 0.2% of recipients. Mostly asymptomatic, these tumors are mainly diagnosed on a routine imaging of the renal transplant. Predominant pathology is clear cell carcinomas but papillary carcinomas are more frequent than in general population (up to 40-50%). RCC of the renal transplant is often localized, of low stage and low grade. According to tumor characteristics and renal function, preferred treatment is radical (transplantectomy) or nephron sparing through partial nephrectomy (open or minimally invasive approach) or thermoablation after percutaneous biopsy. Although no robust data support a switch of immunosuppressive regimen, some authors suggest to favor the use of mTOR inhibitors. CTAFU does not recommend a mandatory waiting time after transplantectomy for RCC in candidates for a subsequent renal tranplantation when tumor stageAsunto(s)

RESUMEN
OBJECTIVE: To define guidelines for the management of renal cell carcinoma of the native kidney (NKRCC) in kidney transplant (KTx) recipients and renal cell carcinoma (RCC) in end-stage renal disease (ESRD) patients candidates for renal transplantation. METHOD: A review of the literature following a systematic approach (Medline) was conducted by the CTAFU to report renal cell carcinoma epidemiology, screening, diagnosis and management in KTx candidates and recipients. References were assessed according to a predefined process to propose recommendations with the corresponding levels of evidence. RESULTS: ESRD patients are at higher risk of RCC with a standardized incidence ratio of approximately 4,5 as compared with general population. NKRCC tumors occur in 1 to 3 % of KTx recipients with a 10 to 15-fold increased risk as compared with general population, especially in patients with acquired multicystic kidney disease. Most authors suggest yearly monitoring of the native kidneys using ultrasound imaging. Radical nephrectomy (either open or laparoscopic approach) is the preferred treatment of NKRCC in KTx recipients and RCC in ESRD. Surveillance in a valid option in small or cystic renal masses. In the localized setting, change in immunosuppressive therapy is not recommended besides perioperative avoidance of mTOR inhibitor to limit morbidity. CTAFU does not recommend a mandatory waiting time after nephrectomy for RCC in ESRD patients candidates for renal tranplantation when tumor stageAsunto(s)

RESUMEN
INTRODUCTION: Bourneville's tuberous sclerosis or Tuberous Sclerosis Complex (TSC) is an autosomal dominant hereditary phakomatosis associated with angiomyolipomas (AML) of the kidney. The aim of this study was to identify the prevalence of TSC in patients diagnosed and cared for AML in our department of urology. MATERIALS AND METHODS: All the patients with AML were included between March 2009 and June 2016 in a French university hospital. Each patient was reviewed in consultation with a clinical examination and imaging. Specific clinical criteria were used to refer patients to genetic analysis. Patients with a high TSC probability had a genetic analysis to search TSC1 and TSC2 genes mutations. RESULTS: In all, 28 patients were included and 3 (11%) were diagnosed TSC. The median age of the patients was 62 years (36-82 years). The most frequent clinical criteria were facial angiofibromas in 7 patients (25%). Among the 8 patients (29%) with evocative clinical criteria, a mutation of the TSC1 and TSC2 genes was identified in 3 patients (11%) with a diagnosis of TSC made before the AML diagnosis. CONCLUSION: In this study, 8 patients (29%) presented clinical criteria suggestive of TSC, preferentially dermatological. The diagnosis was confirmed by screening TSC1 and TSC2 genes mutations in 3 patients (11%), nevertheless prevalence of TSC is most probably underestimated by the genetic mosaïcisme of this pathology.

OBJECTIVE: - To update the French guidelines on kidney cancer. METHODS: - A systematic review of the literature between 2015 and 2020 was performed. The most relevant articles regarding the diagnosis, the classification, surgical treatment, medical treatment and follow-up of kidney cancer were retrieved and included in the new guidelines. The guidelines were updated with corresponding levels of evidence. RESULTS: - Thoraco-abdominal CT scan with injection is the best radiological exam for the diagnosis of kidney cancer. MRI and contrast ultra-sound can be useful in some cases. Percutaneous biopsy is recommended when histological results will affect clinical decision. Renal tumours must be classified according to pTNM 2017 classification and ISUP grade. Metastatic kidney cancers must be classified according to IMDC criteria. Partial nephrectomy is the recommended treatment for T1a tumours and can be done through an open, laparoscopic or robotic access. T1b tumours can be treated by partial or total nephrectomy according to tumour complexity. Radical nephrectomy is the recommended treatment of advanced localized tumours. There is no recommended adjuvant treatment. In metastatic patients: cyto-reductive nephrectomy can be offered in case of good prognosis; medical treatment must be counseled first in case of intermediate or bad prognosis. Surgical or local treatment of metastases should be considered in case of solitary lesion or oligo-metastases. First line recommended drugs in metastatic patients include the associations axitinib/pembrolizumab and nivolumab/ipilimumab. Cystic tumours must be classified according to Bosniak Classification. Surgical excision should be offered to patients with Bosniak III and IV lesions. It is recommended to follow patients clinically and with imaging according to tumour aggressiveness. CONCLUSION: - These updated recommendations should assist French speaking urologists for their management of kidney cancers.

INTRODUCTION: Partial nephrectomy (NP) after embolization of tumor vessels (NPESH) in a hybrid room combines embolization of tumor vessels and enucleation of the tumor under laparoscopy in the same operative time. The purpose of this study was to assess the impact of the use of NPESH in the management of patients treated with surgery for a localized kidney tumor. MATERIAL AND METHODS: Using the uroCCR database, we included all consecutive patients operated in a university hospital for localized kidney tumor. From 2011 to May 2015, patients were treated by Standard Partial Nephrectomy (NPS) Laparoscopic or Open and from May 2015 to May 2019 by NPESH. We evaluated characteristics of patients, tumors, perioperative data and complications. These data were compared by Student and Khi2 tests. RESULTS: 87 NPS were performed during Period 1 and 137 NPS were performed during period 2. The ASA score of patients undergoing NPESH was higher than NPS (P<0.0001). The tumor complexity and median tumor size were similar in the two groups (P=0.852 and P=0.48). The complication rate for NPS and NPESH was 55.2% and 33.6% (P=0.002). There were less severe complications in the NEPSH group (P=0.012). The median length of stay was 8 and 4 days for the NPS and NPESH groups (P<0.0001). Positive surgical margins were 2 (2.3%) and 6 (4.6%) for the NPS and NPESH group (P=0.713). DISCUSSION: NPESH is an efficient technique compared to NPS. It seems to be an interesting alternative to limit renal ischemia, complication rate and length of stay for the management of localized kidney tumors.

OBJECTIVES: During ureteroscopy for urolithiasis, postoperative ureteral drainage with double J stent is frequently used. It may reduce acute postoperative pain and late ureteral stenosis. Double J stent can have negative impact on life quality. After uncomplicated intervention, double J stent is not mandatory. Objective of our study was to evaluate pain and complications after ureteroscopy with or without stent. METHODS: We retrospectively analyzed ureteroscopy performed between May 2014 and January 2017. Interventions were compared regarding ureteral drainage with double J stent or not. Our primary outcome was early postoperative pain evaluated with an oral pain scale form 1 to 10 on day one after intervention. Clinical characteristics, per- and postoperative data were collected. We also looked for risks factors of complications. RESULTS: Three hundred and sixty-six interventions were included, 259 (70.8%) with and 107 (29.2%) without double J stent. Stone burden was higher in stented group (18.3 vs 9.4mm, P<0.0001). Patients without postoperative stents had more ureteral preparation with double J stent (78.5% vs 62.5%, P=0.0032) and had more ambulatory interventions (75.7% vs 52.5%, P<0.0001). Postoperative pain was not different (22% vs 17.75%, P=0.398). Complication rate was similar (29% vs 20.5%, P=0.1181), so was rehospitalization rate (0.8% vs 0.9%, P=1). In multivariate analysis, complications factors were unprepared ureter, experienced surgeons and access sheath. CONCLUSION: Not stenting after ureteroscopy do not increase pain or complications. Stenting should not be used after uncomplicated interventions for centimetric stones. LEVEL OF EVIDENCE: 4.

BACKGROUND AND METHODS: Nephrectomy is the treatment for renal cell cancer from T1-4 tumors but remains at risk. To determine the thirty-day mortality rate after nephrectomy for cancer and to identify causes and risk factors of death in order to find clinical applications. From 2014 to 2017, we performed a retrospective multicentric analysis of prospectively collected data study involving the French network for research on kidney cancer (UroCCR). All patients who died after nephrectomy for cancer during the first thirty days were identified. Patients' characteristics, causes of death and morbidity and mortality reviews reports were analyzed for each death. RESULTS AND LIMITATIONS: In total, 2578 patients underwent nephrectomy and 35 deaths occurred. The thirty-day mortality rate was 1.4%. In univariate analysis, symptoms at diagnosis (P=0.006, OR=2.56 IC (1.3-5.03)), c stage superior to cT1 (P<0.0001, OR=6.13 IC (2.8-13.2)), cT stage superior to cT2 (P<0.0001, OR=8.8 IC (4.39-17.8)), nodal invasion (P<0.0001, OR=4.6 IC (1.9-10.7)), distant metastasis (P=0.001, OR=4.01 IC (1.7-8.9)), open surgery (P<0.0001, OR=0.272 IC (0.13-0.54)) and radical nephrectomy (P=0.007, OR=2.737 IC (1.3-5.7)) were risk factors of thirty-day mortality. In a multivariable model, only cT stage superior to T2 (P=0.015, OR=3.55 IC (1.27-10.01)) was a risk factor of thirty-day mortality. The main cause of postoperative death was pulmonary (n=15; 43%). The second cause was postoperative digestive sepsis for 7 patients (20%). Only 2 morbidity and mortality reviews had been done for the 35 deaths. Limitations are related to the thirty-day mortality criteria and descriptive study design. CONCLUSIONS: Symptomatic patients, stage cTNM and type and techniques of surgery are determinants of thirty-day mortality after nephrectomy for cancer. The first cause of postoperative death is pulmonary. Morbidity and mortality reviews should be considered to better understand causes of death and to reduce early mortality after nephrectomy for cancer. LEVEL OF EVIDENCE: 4.

PURPOSE: For survivors of perineal gangrene (PG), quality of life and functional prognosis of pelvic functions are probably overestimated. The aim of this study was to report long-term anal and urinary sphincter dysfunctions, sexual sequelae, and patients' quality of life after treatment of perineal gangrene. METHODS: This retrospective observational study was conducted in one university hospital over 16 years. Seventy-three patients experienced PG; 22 were subject to long-term follow-up. Three questionnaires were sent to patients to assess pelvic dysfunction and quality of life: the GIQLI, the Cleveland Incontinence Score, and the USP score for urinary dysfunction. Sexual sequelae were considered if orchiectomy or penile resection for male patients and vulvar resection for female patients were performed. RESULTS: Of the 72 patients included, seven died before discharge (9.7%) and at least 14 died during follow-up (19.4%), despite a mean age of 62 years (± 13). Among the surviving patients, seven experienced an alteration of their quality of life (44%) (GIQLI < 96). Six patients still had a colostomy, and among the remaining patients, 11 experienced minimal to mild incontinence (68.7%), while one experienced constipation (6.2%). One patient suffered from urinary incontinence (4.5%), and six suffered from dysuria (27.3%). Three male patients (14%) underwent an orchiectomy, and one female patient (100%) underwent a vulvar resection. CONCLUSION: PG leads to a high rate of anal and urinary dysfunctions. Urinary dysfunctions are taken into account and treated; however, anal incontinence is not investigated even though it could lead to decreased quality of life.

CONTEXT: Nivolumab, an anti-PD1 immune control point inhibitor, is the first treatment that has improved the overall survival of patients after first-line metastatic renal cell carcinoma in 2015. Over the past two years, a large number of trials on these treatments and the interest of associations are being evaluated. OBJECTIVE: In this article, we propose to summarize the clinical development of checkpoint inhibitors to assess the direction of clinical research in this area. DOCUMENTARY SOURCE: A systematic review of the literature was performed in PubMed/Medline database and Meeting Library Asco by searching for articles in French or English published on immunotherapy in renal cell carcinoma. The research was limited to abstracts and articles published from 2014 to 2017. SELECTION OF TRIALS: We identified 349 publications and abstracts and selected 17 references from prospective studies. RESULTS: Recent data on checkpoint inhibitors, as well as their combination with tyrosine kinase inhibitors or with anti-angiogenic agents or with indoleamine 2, 3-dioxygenase 1 in renal cell carcinoma and the latest advances in vaccine therapy have been reported. CONCLUSION: In 2017, immunotherapy combined with other treatments is likely to lead to a paradigm shift in the clinical management of patients. The combination of nivolumab and ipilimumab in the first line will revolutionize the therapeutic management of patients with metastatic renal cell carcinoma.

The management of metastatic renal cell carcinoma had changed over the last ten years with the apparition of new treatments and advances in surgery and ablative techniques. The therapies for metastatic patients have also been personalized and different prognostic groups have been established to adapt the treatment to the severity of the disease. Surgical excision, radiotherapy or ablative therapy could be proposed for patients with isolated metastasis and good condition to delay the systemic therapy initiation. Until 2006, in case of metastatic renal cell carcinoma, immunotherapy (IL-2 and TNF-alpha) was proposed. Targeted therapies acting on angiogenesis mechanisms have also been developed. Recently, immunotherapy has revolutionized the therapeutic management and has improved the overall survival of patients with metastatic renal carcinoma. For each patient, a multidisciplinary management is organized with a personal therapeutic project. This global management needs coordination with the medical team and also need a good communication with the patient, his entourage and his doctor.

BACKGROUND: Partial nephrectomy (PN) is recommended as first-line treatment for cT1 stage kidney tumors because of a better renal function and probably a better overall survival than radical nephrectomy (RN). For larger tumors, PN has a controversial position due to lack of evidence showing good cancer control. The aim of this study was to compare the results of PN and RN in cT2a stage on overall survival and oncological results. METHOD: A retrospective international multicenter study was conducted in the frame of the French kidney cancer research network (UroCCR). We considered all patients aged≥18 years who underwent surgical treatment for localized renal cell carcinoma (RCC) stage cT2a (7.1-10cm) between 2000 and 2014. Cox and Fine-Gray models were performed to analyze overall survival (OS), cancer specific survival (CSS) and cancer-free survival (CFS). Comparison between PN and RN was realized after an adjustment by propensity score considering predefined confounding factors: age, sex, tumor size, pT stage of the TNM classification, histological type, ISUP grade, ASA score. RESULTS: A total of 267 patients were included. OS at 3 and 5 years was 93.6% and 78.7% after PN and 88.0% and 76.2% after RN, respectively. CSS at 3 and 5 years was 95.4% and 80.2% after PN and 91.0% and 85.0% after RN. No significant difference between groups was found after propensity score adjustment for OS (HR 0.87, 95% CI: 0.37-2.05, P=0.75), CSS (HR 0.52, 95% CI: 0.18-1.54, P=0.24) and CFS (HR 1.02, 95% CI: 0.50-2.09, P=0.96). CONCLUSION: PN seems equivalent to RN for OS, CSS and CFS in cT2a stage kidney tumors. The risk of recurrence is probably more related to prognostic factors than the surgical technique. The decision to perform a PN should depend on technical feasibility rather than tumor size, both to imperative and elective situation. LEVEL OF EVIDENCE: 4.

Hybrid operating rooms (HOR) are rooms that mix interventional radiology and surgical equipments. They are usually used in heart, vascular, orthopedic and neurosurgery, and make it possible to consider new minimally invasive procedures in urology. Thanks to these, we developed a new partial nephrectomy technique without renal pedicle clamping and without ischemia. Renal cancer is now diagnosed at localized stage in most of the cases, and its treatment is mostly based on nephron sparing surgery. However, the hemorrhagic character of this intervention requires a renal pedicle clamping whose long-term consequences on renal function are discussed. It also exposes to a classical complication: the renal artery pseudoaneurysm. Therefore, we developed a new laparoscopic partial nephrectomy technique without clamping or approach of renal pedicle, by a selective embolization of tumor vessels through an endovascular route, immediately before the surgery. HOR allowed the combination of the two procedures in the same time and space unit. Tumor staining by Bleu Patenté also aids the surgeon in its spotting. HOR allow a new approach in localized renal cancer management, and should be used in many other urologic surgeries in years to come. They represent a technological advancement by combining interventional radiologists and surgeons' expertise.

INTRODUCTION: Urinary tract infection is the most common healthcare-association infection, especially because of urinary catheter. We evaluated our practices concerning catheter insertion and management in our institution. MATERIALS AND METHODS: We conducted a single-centre descriptive cross-sectional study during 1 week in September 2014 in all adult departments. We noted prevalence, indications, length, management of urinary catheter (UC) and symptomatic catheter-associated urinary tract infections (SCAUTI). RESULTS: Amongst 1046 patients audited, 125 (12%) had UC. The mean age was 72 years (64.8-79.2). UC prevalence was higher in surgical (88%) and medical (87%) intensive care, urology (50%), geriatrics (18%) and long-term care (18%) departments. The average catheterisation length was 7.8 days (3.8-11.8); it was shorter in surgery than in medicine departments (3.6 vs 9.7 days, P<0.001). Catheters were present for more than 4 days in 60% of the cases. Acute urinary retention was the most frequent indication (59%), significantly more in medical than surgical departments (75% vs 26%). Others indications were perioperative (17%), diuresis monitoring (12%), strict immobilization (4%) and unnecessary indications or staff comfort (4%). A SCAUTI was present in 10% of cases, mostly in medicine department (30% vs 8%). CONCLUSION: The prevalence of our institution is higher than the national prevalence (8.1%), but still below the European average (17.2%). Control of the risk of CAUTI requires compliance with UC appropriate indications, UC management, and prompt removal of unnecessary UC. LEVEL OF EVIDENCE: 4.

Recent years have seen important advances in our understanding of the etiology, biology and genetics of kidney cancer. To summarize important achievements and identify prominent research questions that remain, a workshop was organized by IARC and the US NCI. A series of 'difficult questions' were formulated, which should be given future priority in the areas of population, genomic and clinical research.

INTRODUCTION: Targeted molecules are used in the treatment of metastatic kidney cancer. Their use before surgery could reduce tumor volume, facilitate surgical resection and treat micrometastases. In this literature review, we present the main results of studies that evaluated the benefit of targeted therapies in kidney cancer. METHODS: This article is based on a systematic literature search by using Pubmed database. RESULTS: In prospective studies, a decrease in the size of the primary tumor has been reported to be 9.6 to 28.3%. In case of metastatic kidney cancer, cytoreductive nephrectomy could be possible after targeted therapies in tumors that initially were not available for surgery. In localized kidney cancer, a reduction of tumor volume of more than 30% is obtained in 5 to 45% of cases after neoadjuvant targeted therapies. Their use is associated with the occurrence of the usual side effects of targeted therapies plus a specific risk of delayed healing and metastatic progression during the perioperative period. The study of tumors after surgery shows a lower efficiency of the production of tumor necrosis in non-clear cell carcinomas. CONCLUSION: Data from the literature are not currently in favor of neoadjuvant use of targeted therapies in the treatment of kidney cancer. Prospective studies will be required to determine their interest in the prevention of metastatic recurrence after surgery.
