RESUMEN
PURPOSE: End-to-end (ETE) pyeloureterostomy is an alternative to ureteroneocystostomy for urinary anastomosis during kidney transplantation (KT). In preemptive KT from living donors (PKT-LD), end-to-side (ETS) uretero-ureteral anastomosis could have the benefits of pyeloureterostomy without ligation of the native kidney ureter. This study aimed to compare ETS to ETE uretero-ureteral anastomosis in PKT-LD. METHODS: A monocentric retrospective 8-year study included all consecutive cases of PKT-LD, excluding ureteroneocystomy anastomosis and homolateral nephrectomy. Two groups were compared: ETS and ETE. Perioperative data on graft function and urological complications were collected. RESULTS: One hundred and six patients were included: 48 patients in the ETS group and 58 patients in the ETE group. Median follow-up was 37.5 months [17.3; 57.5]. The estimated glomerular filtration rate at postoperative day ten and 3 months was similar in both groups. The overall complication rate was 16%, with no significant difference between the 2 groups. There was one ureteral stenosis in each group. None of the patients in the ETS group presented urinary fistula, whereas it occurred in one (1.7%) in the ETE group. Back pain due to native kidney obstruction occurred in 5 patients in the ETE group (8.6%), but not in the ETS group. CONCLUSION: In preemptive kidney transplantation from living donors, urinary anastomosis can safely be performed as an end-to-side uretero-ureteral anastomosis, with low urological complications. It could prevent symptoms and complications due to native kidney obstruction. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Inflammatory and sensory chronic bladder diseases have a significant impact on quality of life. These pathologies share alteration of the layer between urine and urothelium, making the use of topical agents appropriate. OBJECTIVES: Review the efficacy and tolerance of intravesical treatments for these pathologies. Give practical guidelines for the use of agents currently available in France. METHOD: A narrative review was performed in March 2021 using PubMed/MEDLINE, Google Scholar and the international guidelines. Pharmaceutical companies and pharmacies were interviewed. RESULTS: Although numerous molecules were tested over the last 5 decades, only dimethylsulfoxyde and glycosaminoglycans are available in France today. Results are promising: response rates are up to 95% and 84% respectively in bladder pain syndrome. In urinary tract infections, glycosaminoglycans could decrease annual number of cystitis by 2.56 (95% confidence interval (CI) -3.86, -1.26; P<0.001) and increase the time to first cystitis recurrence by 130 days (95% CI: 5.84 - 254.26; P=0.04). In radiation cystitis, results could be comparable to hyperbaric oxygen regarding pain and frequency of voiding (-1.31±1.3 visual analogic scale et -1.5±1.4 voiding per day, respectively, at 12 months, P<0.01). However, literature has a low level of evidence. CONCLUSION: Chronic bladder diseases have limited treatment options. Intravesical agents are a good alternative, although their cost is significant and their outcome uncertain.

OBJECTIVE: To determine the usefulness of mid-urethral slings (MUS) in the surgical management of women presenting with urinary stress incontinence (USI) METHOD: A consensus committee of multidisciplinary experts (CUROPF) was convened and focused on PICO questions concerning the efficacy and safety of MUS surgery compared to other procedures and concerning which approach (retropubic (RP) vs transobturator (TO)) should be proposed as a first-line MUS surgery for specific subpopulations (obese; intrinsic sphincteric deficiency (ISD); elderly) RESULTS: As compared to other procedures (urethral bulking agents, traditional slings and open colposuspension), the MUS procedure should be proposed as the first-line surgical therapy (strong agreement). MUS surgery can be associated with complications and proper pre-operative informed consent is mandatory (strong agreement). Mini-slings (SIS/SIMS) should only be proposed in clinical trials (strong agreement). Both RP and TO approaches may be proposed for the insertion of MUS (strong agreement). However, if the woman is willing to accept a moderate increase in per-operative risk, the RP approach should be preferred (strong agreement) since it is associated with higher very long-term cure rates and as it is possible to completely remove the sling surgically if a severe complication occurs. The RP approach should be used for the insertion of MUS in a woman presenting with ISD (strong agreement). Either the RP or TO approach should be used for the insertion of MUS in an obese woman presenting with USI (strong agreement). In very obese women (BMI ≥35-40kg/m2), weight loss should be preferred prior to MUS surgery and bariatric surgery should be discussed (strong agreement) CONCLUSION: The current Opinion provides an appropriate strategy for both the selection of patients and the best therapeutic approach in women presenting with USI.

INTRODUCTION: Placement of a mid-urethral sling is the gold standard in the surgical management of stress urinary incontinence in women in France. The cure rate of this material is no longer to be demonstrated, but the per- and post-operative complications are currently the subject of a growing controversy not only in Europe but also across the Channel and across the Atlantic, having led to the modification of operative indications. In France, recommendations are also evolving with a stricter framework for indications for surgery by multidisciplinary consultation meeting and an obligation for postoperative follow-up in the short and long term. OBJECTIVES: In this context, CUROPF realized a review of the literature bringing together the available scientific evidence concerning the occurrence of per- and post-operative complications relating to the installation of mid urethral sling. The bibliographic search was carried out using the Medline database and 123 articles were selected. RESULTS: Analysis of the data highlights various complications, depending on the implanted material, the patient and the indication for surgery. The retro-pubic mid urethral sling provides more bladder erosion during surgery (up to 14%), more suprapubic pain (up to 4%) and more acute urinary retention (up to 19,7%) and postoperative dysuria (up to 26%). The trans obturator mid-urethral sling is responsible for more vaginal erosion during the operation (up to 10,9%), more lower limb pain of neurological origin (up to 26,7%). The risk of developing over active bladder is similar in both procedures (up to 33%). But these risks of complications must be balanced by the strong impact of urinary incontinence surgery on the overall quality of life of these women. CONCLUSION: Thus, surgical failure and long term complications exist but should not limit the surgical management of stress urinary incontinence with mid urethral tape. Women should be treated with individualized decision-making process and long-term follow -up is necessary.

BACKGROUND: The success of minimally invasive parathyroidectomy (MIP) relies on accurate localization of the abnormal parathyroid glands. Concordant findings on ultrasound (US) and 99mTc-scintigraphy (sestamibi) are currently considered the 'gold standard'. Computed tomography (CT) has also recently been used in preoperative planning. We sought to assess the accuracy of CT for localization of abnormal parathyroid glands in such patients. METHODS: An audit of 75 patients with primary hyperparathyroidism (PHPT) who underwent neck US and CT between 2017 and 2019 at our center as their first-line imaging. RESULTS: All 75 patients underwent US and CT and 54 (72.0%) also had sestamibi. CT alone identified a potential target in all patients, of which the location was correct in 63 (84.0%). The overall combined sensitivity of US and CT was 88% (95% CI 78-94) and was higher than the combined sensitivity of US and sestamibi (65% [95% CI 53-76]; p < 0.001). Twenty-one patients (28.0%) had an ectopic gland, and the sensitivity of US and CT was 86% (95% CI 64-96) versus US and sestamibi (57% [95% CI 34-77]; p = 0.016). For adenomas < 1.0 g (n = 36; 48%), the accuracy of CT was 81% (95% CI 64-91) compared with 62% (95% CI 44-77) for US and sestamibi (p = 0.04). The correct preoperative diagnosis of multiglandular disease (n = 9; 12%) seemed to be the most difficult, with similar accuracy for US and sestamibi (40% [95% CI 14-73]) and US and CT (50% [95% CI 20-80]) (p > 0.99). CONCLUSION: The combination of US and CT was able to correctly identify the location of the abnormal parathyroid in 88% of patients and, in comparison with US and sestamibi, had better diagnostic accuracy, especially for smaller and ectopic adenomas. This finding suggests that US and CT could be considered as a first-line imaging modality in patients with PHPT considered for MIP.

Given the recent increase in the number of human papillomavirus (HPV)-induced cancers in other locations than gynaecological, the number of patients with two cancers at distinct sites, and because of the lack of exhaustive data, we decided to create a multidisciplinary network around an HPV consultation at the Georges-Pompidou European Hospital (HEGP). This network aims to set up the best tools for detecting HPV-associated "multisite" precancerous lesions in order to determine the possible impact of dedicated care for this at-risk population. This monthly consultation was created at the HEGP in June 2014. It is currently organized around five consultations: gynaecological, ENT, urological, digestive and immunological. Every patient who has been diagnosed with HPV-related cancer and whose care is provided at the HEGP is offered this particular follow-up: systematically, once the initial lesion has been treated, the patient is convened annually for a day during which it benefits from the consultations mentioned above. A consultation with a psychologist is systematically proposed. Local samples are taken at each site: a cytological examination, the analysis of known predictive and prognostic virological markers are carried out. This study fits more broadly in a theme of clinical and fundamental research around cancers related to HPV.

INTRODUCTION: Elderly patients represent a growing part of our society for who treatment strategy for localized renal tumors has to be chosen knowing iatrogen effects and renal function morbidity. The aim was to analyze oncological and functional results of nephron sparing surgery (PN) versus radiofrequency ablation (RFA). MATERIALS AND METHODS: All patients aged more than 75 treated by partial nephrectomy or radiofrequency ablation between 2007 and 2014 in our centre were included. Patient and tumors data were compared and these criteria were analyzed: survival (overall and without recurrence) and loss of renal function (pre- and postoperative MDRD). RESULTS: In total, 100 patients were included (26 partial nephrectomies, group 1 and 74 radiofrequency ablation, group 2) with a 32-months medium follow-up. Medium age and tumor size were significantly different (respectively, 78 versus 81 years old, P=0.001, 38mm versus 29mm, P=0.003). Perioperative results showed no differences in complications. Transfusion rate and duration of hospital stay were significantly higher in the PN group. Median overall survival were 45 vs. 27 months (P=0.23) for PN and RFA and median recurrence-free survival were 28 vs. 10 months (P=0.34). On a multivariate analysis, operative technique (PN or RFA) were not significantly linked to survival (HR 2.37 [95% CI: 0.66-8.5]), P=0.19. Loss of renal function were 1.5±14mL/min/1.73m2 for PN and 3±14mL/min/1.73m2 for RFA (P=0.69). CONCLUSION: Our study showed better perioperative results for RFA than for PN, without significant different survival. Loss of renal function were little and similar. LEVEL OF EVIDENCE: 4.

OBJECTIVES: To describe lower urinary tract symptoms (LUTS) and their management in renal transplant candidates and recipients. MATERIAL AND METHODS: Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association: "transplantation", "prostate hyperplasia", "transurethral resection of prostate", "urinary incontinence", "LUTS", "pelvic floor dysfunction". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and case reports were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 991 articles were analyzed and after careful selection, 47 publications were eligible for our review. RESULTS: Reduction of bladder capacity, due to dialysis and anuria, is correlated with dialysis duration. This reduction is reversible after renal transplantation and does not seem to put renal transplant recipients at risk for medical complications. Transplant procedure generally allows restoration of bladder maximal output, normal bladder capacity and compliance. Medical treatment of LUTS related to prostate hyperplasia (BPH) includes alpha-blockers and finasteride. Silodosin and dutasteride have not been evaluated in that setting. Antimuscarinics may be used with caution, and favor the use of solifenacin at 5mg per day. Surgical treatment of BPH requires a preserved urine output, otherwise must be delayed after transplantation; it may thus be performed safely in the early postoperative course. Botulinum toxin injections and surgical treatment of stress incontinence and prolapse are barely reported in this population. CONCLUSION: Precise assessment and optimal management of LUTS in renal transplant candidates and recipients are critical to improve quality of life and to preserve allotransplant function. Literature data lack evidence to propose robust recommendations. However, knowledge of reported specificities in this peculiar setting is mandatory for urologists to provide patients with finest options and optimal treatment timing.

AIM: To evaluate in a high volume center the practice and the performance of cancer genetic screening for patients with multiple renal tumors without a predisposition to kidney tumors known at the time of surgery. METHOD: All patients treated for multiple renal tumors from January 2000 to December 2013 in our center were included. Patients with a family history of renal cell carcinoma, a kidney disease or a genetic predisposition to renal cancer known at the time of surgery were excluded from the analysis. Our list of patients was retrospectively compared to the records from PREDIR (PREDisposition to Kidney Tumors) center of Île-de-France, which regionally centralizes the care of patients with kidney tumors associated with a genetic predisposition. RESULTS: One hundred and thirty-six patients were included. Twenty-six patients of 136 (19%) were referred to PREDIR center: 23 followed the screening and 3 did not show up in consultation. Of the 23 patients screened, three genetic predispositions to kidney tumors were identified (13%). Of the 95 patients with synchronous tumors, 48% with more than 3 tumors benefited from cancer genetics investigation against 13% of those presenting only two tumors. CONCLUSION: Our study shows that cancer genetic investigations are not routinely offered to patients with multiple kidney tumors, conversely to existing guidelines. Urologists must be aware of this screening. LEVEL OF EVIDENCE: 4.

OBJECTIVES: Ureteral stents and ureteral catheters externalized through the urethra are not ideal solutions to manage complicated upper urinary tract fistulae. We sought an effective method of drainage, minimally invasive, reproducible allowing a rapid patient's discharge. PATIENTS AND METHODS: Between November 2013 and February 2015, an ureteral stent was exteriorized in trans-vesico-parietal by an endoscopic and percutaneous access in patients with complicated upper urinary tract fistulae. Monitoring of tolerance, complications and urinary fistula healing was performed. RESULTS: Nine consecutive patients had an ureteral stent exteriorized in trans-vesico-parietal to manage complicated upper urinary tract fistulae. There was no failure in introducing the catheter, or postoperative complication. Catheters were left in place on average 36.1days (24-55). The patients were able to return home with the catheter in place in 77.8% of cases. The tolerance of the catheter was good. All fistulae were able to be treated conservatively at the end of the drainage period. CONCLUSION: Trans-vesico-parietal ureteral catheters enable efficient and reproducible conservative treatment of upper tract urinary fistulae regardless of their cause. LEVEL OF EVIDENCE: 5.

Glutathione peroxidase-1 (GPx-1) is an endogenous anti-oxidant enzyme. The T allele of the GPx-1 rs1050450 (C > T) gene variant is associated with reduced enzyme activity. Our aim was to examine the association between this gene variant and peripheral neuropathy in two cross-sectional samples of subjects with diabetes: (i) 773 Caucasian subjects were genotyped from the UCL Diabetes and Cardiovascular disease Study (UDACS) and (ii) 382 Caucasian subjects from the Ealing Diabetes Study (EDS). Peripheral neuropathy status (and oxidised-LDL [Ox-LDL:LDL] and plasma Total Ant-ioxidant Status [TAOS] in UDACS), were analysed in relation to genotype. We observed that: (i) In UDACS, the odds ratio (OR) for peripheral neuropathy in the T allele carriers compared to the CC genotype was 1.61 [1.10-2.28], p = 0.01. This remained significant after adjustment for other risk factors. Ox-LDL:LDL ratio was significantly elevated in T allele carriers (CC vs. CT/TT: 16.3 ± 2.4 v 18.0 ± 2.9 U/mmol LDL, p = 0.02). (ii) In EDS, the OR for peripheral neuropathy in the T allele carriers compared to the CC genotype was 1.95 [1.11-3.42], p = 0.02. This remained significant after adjustment for other risk factors. In conclusion, we observed a significant association between the T allele and peripheral neuropathy and LDL oxidation. This is the first paper to examine the rs1050450 variant in two samples of Caucasian subjects with diabetes. Prospective analysis of the gene variant is required in diabetic and healthy cohorts with measured plasma markers of oxidative stress to investigate the described association further.
