RESUMO
PURPOSE: Bladder infusion, which involves filling the bladder with saline prior to catheter removal, has been associated with reduced time-to-discharge and increased success rates in trials without catheter (TWOCs) in perioperative setting. The objective of this study was to evaluate the applicability of this protocol in patients with acute urinary retention (AUR) related to benign prostatic hyperplasia (BPH). METHODS: We conducted a retrospective single-center study comparing bladder infusion with at least 150mL of warm saline vs. standard catheter removal during TWOC in patients with BPH-related AUR between January and December 2021. The primary outcome was time to discharge. Secondary outcomes included: TWOC success, and early recurrence of urinary retention defined as recurrence within three months of successful TWOC. RESULTS: A total of 75 men were included: 35 in the bladder infusion protocol and 40 in the standard protocol. Baseline characteristics were well balanced between groups. Overall, 35 patients (46.7%) had a successful TWOC without statistically significant difference between groups (P=0.10). Bladder infusion protocol was associated with a shorter median time to discharge (200 vs. 240min, P=0.003). However, patients in the bladder infusion group were associated with a higher risk of early recurrence of urinary retention (30% vs. 0%, P=0.02). CONCLUSION: In patients with BPH-related AUR, the saline bladder infusion method reduced time-to-discharge with similar TWOC success rates. Larger studies are needed to properly analyze the risk of early recurrence of urinary retention before any clinical application. LEVEL OF EVIDENCE: III.

AIM: To determine the surgical indication and results of bladder augmentation (BA) during the last decade in a neurourology center in the era of intradetrusor botulinum toxin injection. MATERIAL: We conducted a retrospective study that included patients with BA between January 1, 2012 and December 31, 2022 in our centre. We collected pre-operative demographic, clinical, and urodynamic data, BA indication, and associated procedures. We analyzed early and late complications as well as continence and postoperative voiding mode in patients with first BA in a neurological pathology context. RESULTS: We performed 77 BA over the study period. The main indication was neurogenic overactive bladder, which was secondarily resistant to botulinum toxin. The main associated procedure was continent cutaneous diversion (n=31, 57.4%). Among patients who had a first BA for neurogenic bladder, 34 patients had early complications (50%) including 12 patients with≥Clavien 3 complications (17.6%). After a median follow-up of 33 [14; 55] months, 23 patients had late complications (33.8%) and 59 patients had complete continence (86.8%). CONCLUSION: In the era of botulinum toxin, the main indication of BA is the secondary failure of botulinum toxin for overactive neurogenic bladder. The BA provided continence in 86.8% of patients. It remains however an intervention with a significant rate of severe complications whose indication must be discussed by a multidisciplinary team. LEVEL OF EVIDENCE: Weak.

OBJECTIVES: To evaluate the feasibility, efficiency, and predictive factors of therapeutic success of Vibration, Diuresis and Inversion (VDI) therapy for the removal of upper urinary tract stones. METHODS: It is a retrospective, single-center study at the CHU - La Conception, Marseille, France including all patients treated with VDI from 2013 to 2018. VDI was indicated for stones <6mm in first-line treatment or for residual fragments <6mm after ureteroscopy, PCNL, microPCNL. The protocol included 4 sessions in outpatient care from 2013 to 2015 then 6 sessions from 2015 to 2018 and a final radiological evaluation. RESULTS: In total, 109 patients or 489 sessions are reported: median age was 55 years [14-84], median BMI 25kg/m2 [15-37], average cumulative size of kidney stones 3mm ±4. VDI was performed after flexible ureteroscopy (62%), SWL (20%), percutaneous treatment (9%) or as a first-line treatment (9%). Compliance was 87 %. The median VAS during the session was 0[0-8]. The incidence of post-session renal colic was 4% (all Clavien I). The postoperative fragment-free and microfragment rates were respectively 39% and 21%, i.e. an overall success of 60% for kidney stones, and 43% and 21%, i.e. an overall success of 64% for lower pole kidney stones. CONCLUSION: VDI is a simple, non invasive and well tolerated technique for the elimination of small renal lithiasis after SWL, ureteroscopy, PCNL or as a first-line treatment.

PURPOSE: To report the multi-institutional outcomes of Microperc for nephrolithiasis and to assess its feasibility in outpatient care. METHODS: We retrospectively identified all adult patients who underwent Microperc for renal stones at three centres between May 2015 and March 2021. Interventions were performed by three Surgeons. One Surgeon adopted a "one-way" strategy and all Microperc were performed on an outpatient basis, while the other two Surgeons provided inpatient monitoring for at least one day after surgery. The primary endpoint was same-day discharge after Microperc without emergency department visits or unplanned readmission within 30 days of the procedure. The secondary endpoints included treatment outcomes and the 30-day complication rate. RESULTS: Out of 72 consecutive patients included, 32 patients (44.4%) had same-day discharge. Median Charlson score (1 [0-2]) and cumulative stone size (15 [12-20] mm) were comparable between both groups. At one month post procedure, 32 patients (44.4%) were stone free and 23 patients (32%) had residual micro-fragments<3mm, conferring an overall success rate of 76.4% (inpatient Microperc group: 77.5% vs outpatient Microperc group: 75%, P=1). Analysis of the 30-day complication rate showed similar results between the two groups (Clavien I-II: 18.1%, Clavien≥III: 4.1%). After outpatient care, the rate of immediate admission and unplanned readmission was 12.5% (n=4), mainly due to urinary tract infection. CONCLUSION: In this multi-institutional study, we report that outpatient Microperc is feasible in selected patients with no significant impact on postoperative outcome.

PURPOSE: To report our management of preoperative polymicrobial urine culture and to determine its correlation with the risk of postoperative urinary tract infection (UTI). PATIENTS AND METHODS: We retrospectively identified all patients with preoperative polymicrobial urine culture in our center between January 2017 and October 2019. Preoperative urine cultures were collected 5 to 8 days before the surgery. No antibiotic prophylaxis was administered preoperatively in the absence of pyuria. Patients with pyuria (≥10 leukocytes/mm3) were treated preoperatively with Ceftriaxone. In case of beta-lactam allergy, the choice between other antibiotic therapies was left to the surgeon's discretion. A second urine culture was collected the day before surgery. The primary endpoint was the occurrence of UTI within 15 days following surgery. RESULTS: In all, 690 patients were included in the study. In line with our protocol, patients had Ceftriaxone, Fluoroquinolones, another antibiotic or no antibiotic prophylaxis in 492 cases (71.3%), 22 cases (3.2%), 31 cases (4.5%), and 145 cases (21%), respectively. The overall sterilization rate of 40.4% was similar between each treatment arm (P=0.54). Postoperative UTI occurred in 68 cases (10.5%). In multivariate analysis, a sterile urine culture the day before surgery was the only factor decreasing the risk of postoperative UTI (OR 0.39, 95%CI, 0.17-0.84; P=0.022). CONCLUSIONS: Our findings suggest that empirical antibiotic therapy for the treatment of preoperative polymicrobial urine culture is no longer adequate. Further evaluation of organisms isolated may provide the necessary antibiograms for initiation of susceptibility based antibiotic therapy that could decrease postoperative UTI rates.

INTRODUCTION: The development of robot-assisted urological surgery is held back by the lack of robust medico-economic analyses and their heterogeneity. We conducted a medico-economic study to evaluate the implementation of measures to optimize the transition to robotic surgery. METHOD: We carried out a single-center, controlled study from the point of view of the public healthcare establishment for 4 years. Economic data collection was based on a micro-costing method and revenues from stay-related groups. Clinical data corresponded to mean lengths of stay, operating duration, complications and stays in intensive care. The measures to optimize the transition to robotic, implemented mid-study period, enabled before/after comparison. RESULTS: Altogether, 668 patients undergoing robotic surgery were included. Robotic activity increased significantly from periods 1 to 2 to 256% (P=<0.001) as did the overall proportion of robotic by 45% to 85% (P=<0.001). The mean lengths of stay fell significantly, 6.8 d vs. 5.1 d (P<0.001). Costs and revenues increased significantly, resulting in a persistent deficit for the activity 226K vs. 382K (P=<0.001). With increased volume of activity, the deficit per operation and the cost per minute of robotic operating room fell significantly, 3,284 vs. 1,474/procedure (P=<0.001) and 27 vs 24/min (P=<0.029), tending towards a break-even point (=zero deficit) at 430 operations per year. CONCLUSIONS: Robotic-assisted surgery can be significantly optimized by implementing measures for the robotic turn to reach a break-even point at 430 operations per year. A better multidisciplinary case mix could lower the break-even volume of activity in short term. LEVEL OF EVIDENCE: 3.

PURPOSE: To report our preliminary experience with water vapor thermal therapy with the Rezum™ System and Prostate Artery Embolization (PAE) for treatment of medically refractory, complete urinary retention to achieve successful cessation of catheter dependency in frail-patients. PATIENTS AND METHODS: A multi-institutional study was conducted including all patients who underwent Rezum™ procedure and PAE between October 2017 and June 2020. The included population focused on frail-patients unsuitable for conventional surgery with complete urinary retention. Rezum™ patients were identified and matched (1:1) with patients who underwent PAE. The matching criteria were age, Charlson score, prostate volume and duration of follow-up. The primary outcome was catheter-free survival, defined as spontaneous voiding and release from catheter dependence. RESULTS: Eleven patients from the Rezum™ group were matched to 11 embolized patients. PAE and Rezum™ patients were comparable in age (median: 77 vs. 75 years), Charlson score (median: 6 vs. 6) and prostate volume (74 vs. 60 cc). Procedures were significantly longer in the PAE group compared to the Rezum™ procedures (median: 148 vs. 8min, P<0.001). After a median follow-up of 12 months, spontaneous voiding was conserved in all cases (100%) after the Rezum™ procedure and in 5 cases (45.4%) after PAE (P=0.01). In catheter-free patients, the rate of benign prostatic hyperplasia medication use after procedure was 40% for PAE and 18.2% for Rezum™ patients (P=0.54). CONCLUSIONS: Our preliminary experience for treatment of complete urinary retention in frail-patients shows the feasibility of PAE and Rezum™ to restore spontaneous urination without being associated with the occurrence of major complications. Early data suggests that Rezum™ may provide superior results in terms of cessation of catheter dependence. Future studies are needed to definitively assess which treatment would be best suited for each patient. LEVEL OF EVIDENCE: 3.

INTRODUCTION: Sate of the art on the indications, methods of implementation and medico-economic considerations of reusable flexible ureteroscopes (URSr) vs single use (URSuu)? METHOD: Review of the literature (Pubmed) on reusable and single-use ureteroscopes, as well as on the expertise of our center. A PubMed search and narrative review of the data was performed in July 2021. Only articles in French or English were selected. RESULTS: The URSr and URSuu have similar technical characteristics and are suitable for the exploration of the upper urinary excretory tract: treatment of stones of the kidney <2cm or of the ureter. The URSr is the most common type of ureteroscope. URSuu are newer and associated with many advantages: no sterilization procedure, immediate availability of equipment in the operating room, reduced waste production at the institutional level. A hybrid use of URSr and URSuu currently seems to be the best compromise from a medico-economic point of view for high volume centers. In the case of a smaller activity or a secondary site, URSuu are more advantageous and the reduction in purchasing costs should accentuate this benefit. CONCLUSION: URSr and URSuu are technically similar and allow identical treatment of upper urinary tract pathologies. Their complementary use optimizes the care of urology patients. The barrier to the exclusive use of URSuu remains their cost.

OBJECTIVE: To evaluate the long-term oncological and functional results of the ablative treatment of T1a kidney malignancies by percutaneous radiofrequency (RF). MATERIALS AND METHODS: Monocentric retrospective study including all patients treated for renal cell carcinoma (RCC) T1a by radiofrequency, in our center, from 2005 to 2009. All patients had a tumor biopsy before treatment. The primary endpoint was local recurrence. A total of 44 RCCs in 41 consecutive patients were treated (1 patient had 3 synchronous tumors and 1 patient had 2 tumors). There were 26 clear cell RCCs, 13 papillary RCCs and 5 chromophobe RCCs. The median age at diagnosis was 70 years [48-82]. The median American Society of Anesthesiologists (ASA) score was 2 [1-3] and the median glomerular filtration rate (GFR) was 64mL/min [26-109]. Furhman grade was defined for 39 tumors (Clear cell RCC and papillary RCC), of which 82% were grade 1-2. The median tumor size was 20mm [11-40], and the median RENAL score was 4 [4-6]. Complications were assessed according to the Clavien-Dindo classification. Overall survival, recurrence-free survival and metastasis-free survival were calculated using the Kaplan-Meier method. RESULTS: Median follow-up was 90.5 months [17.8-145.3]. Three (7%) local recurrences were reported within a median of 26 months [12-93]. All were treated by a 2nd RF. The overall 10-year survival was 70% (95% CI [56-85]). The 10-year recurrence-free survival was 72% (95% CI [57-88]). The 10-year metastasis-free survival was 87% (95% CI [74-97]). The median GFR on the date of the last news was 51mL/min [16-98] (P=0.05). Post-RFA complications consisted in 5 (11.3%) Clavien-Dindo 1-2 complications. No high grade (Clavien ≥3). CONCLUSION: Percutaneous radiofrequency for RCC T1a is an alternative. It appears to be safe with low morbidity, satisfaying long-term oncological and functional results, but a risk of reprocessing of 7%. LEVEL OF EVIDENCE: 3.

INTRODUCTION: During idiopathic Parkinson's disease (IPD), lower urinary tract symptoms and dysfunctions are frequent, dominated by overactive bladder and detrusor overactivity (OAB, DO). Intradetrusor Injection (IDI) of Botulinum Toxin A (BTA) is recommended as second-line treatment for neurogenic urinary incontinence related to DO in multiple sclerosis or spinal cord injury patients. However, there is little data on BTA IDI to treat incontinence owing to OAB and DO during idiopathic Parkinson's disease. The objective of this study is to evaluate efficacy and tolerance of BTA IDI in patients suffering IPD. PATIENTS AND METHODS: We conducted a retrospective study in IPD patients treated with BTA IDI from 2012 to 2018. For each patient we compared patient clinical and urodynamic data at baseline before the first injection and 8 weeks following the injection. We defined 3 levels of effects (perfect, improved, failure), corresponding to 3-dimension composite criteria: clinical, quality of life (Likert scale), urodynamics. RESULTS: Sixteen patients were included from 2012 to 2018. The median age was 73 (70-78.25). The median number of micturition/day before and after TBA was 13 (10-16) and 9 (6.75-13.25) (p=0.022). The median number of pad used/day before and after BTA was 5.4 (2-5) and 1 (0-5) (p=0.035). Median USP scores for OAB was 15.5 (11.75-20) and 14 (6.75-15.25). Median score on the Likert scale was 1 (0-1.5) meaning "slight improvement" felt by the patient. The median maximum cystometric capacity raised from 130cm3 (41.25-187.75) to 217cm3 (165-376.75) (p=0,013). Among the patients, 20% had a perfect result, 40% were significantly improved and in 40% TBA injections failed. After TBA 4/14 patients (28%) needed intermittent self-catheterization. No severe side effect was observed. CONCLUSION: In this retrospective study we observe some short-term efficacy of TBA IDI to treat urinary incontinence owing to OAB/DO in patients with IPD in 60% of patients. These results are consistent with findings from previous retrospective studies. Prospective data coming from larger cohorts are now tremendously needed to clarify the best patient responders profiles, the actual TBA dose, and eventually to define TBA IDI place in the therapeutic algorithm of IPD patients' incontinence.

OBJECTIVE: To compare the perioperative complications of patients who underwent flexible ureteroscopy (fURS) for the treatment of urinary stones according to the type of ureteroscope used, single-use (suURS) or reusable (rURS) flexible ureteroscope. PATIENTS AND METHODS: A retrospective and single-center study was conducted between January 2017 and May 2019, including all fURS performed for nephrolithiasis management. During the study period, 5rURS and 1suURS (UscopePU3022™) were available. The primary endpoint was the occurrence of 30-days postoperative complications, especially infectious complications, classified according to Clavien-Dindo grading system. RESULTS: Overall, 322 consecutive fURS were included corresponding to 186 rURS (57.8%) and 136 suURS (42.2%). Respectively in rURS and suURS groups, the median (IQR) age was 57 (45-65) vs. 57 (44-66) years (P=0.75), 83 (44.6%) vs. 63 (46.3%) female were included (P=0.82), and median (IQR) Charlson score was 2 (1-3) vs. 2 (0-3) (P=0.15). Fifty-one patients (15.8%) developed postoperative complications, 28 patients (15%) in rURS group and 23 patients (17.6%) in suURS group (P=0.64). Most of them (n=47, 92.1% of overall complications) were minor (Clavien I-II). Occurrence of urinary tract infection in suURS group (n=13; 9.5%) was equally comparable with rURS group (n=10; 5.4%), P=0.15. CONCLUSIONS: Our data suggests that suURS represents a safe alternative to rURS. Compared to reusable devices, UscopePU3022™ use was associated with a similar complication rates, however, did not decrease the occurrence of infectious events. LEVEL OF EVIDENCE: 3.

OBJECTIVES: To evaluate the efficacy of Continuous Saline Bladder Irrigation (CSBI) after blue light transurethral resection of bladder tumor (TURBT) to prevent recurrence of low- to intermediate-risk Non-Muscle Invasive Bladder Cancer (NMIBC). PATIENTS AND METHODS: We conducted a retrospective study including patients with low- to intermediate-risk NMIBC who underwent TURBT in two urological centers between January 2017 and December 2018. Each TURBT was performed using blue light after intravesical instillation of hexaminolaevulinic acid. The experimental group included patients who received CSBI while the control group included patients without CSBI. When practice, CSBI was started immediately after the surgery and was interrupted 24 hours thereafter. Low-risk NMIBC had a surveillance while intermediate NMIBC had 8 adjuvant endovesical instillations of Mitomycin. The primary endpoint was bladder tumor recurrence free-survival which was defined as the time between the initial TURBT and the date of TURBT for bladder recurrence. RESULTS: A total of 167 patients (median age: 71 years) were included: 20% female, 15% low-risk, 85% intermediate-risk NMIBC. CSBI was performed in 95 cases (57%). No complication related to irrigation was reported. Bladder recurrence was observed in 55 cases (32.9%): 22 (23.1%) in the CSBI group vs. 33 (45.8%) in the control group (P=0.002). Multivariate stepwise logistic regression analysis with backward selection revealed that CSBI (HR 0.47 [0.27-0.81]; P=0.006) and MMC (HR 0.55 [0.31-0.95]; P=0.034) were significantly associated with reduced risk of bladder recurrence. CONCLUSIONS: Continuous saline bladder irrigation reduced the risk of bladder recurrence after blue light TURBT in patients with low- to intermediate-risk NMIBC while being safe. Prospective randomized study is needed to confirm these results. LEVEL OF EVIDENCE: 3.

Chronic kidney disease is a gradual and irreversible decrease in the functioning of the kidneys, which no longer filter the body's blood properly. The main causes are diabetes and high blood pressure. With the aging of the population, it is a disease whose incidence is increasing. In the terminal stage of the disease, treatment of replacement of the renal function is necessary (by hemodialysis, peritoneal dialysis or renal transplantation). Currently, kidney transplantation is the best replacement treatment for kidney function, because it is more efficient than dialysis in terms of survival, quality of life and cost to the health system. But it requires the maintenance and monitoring of immunosuppressive therapy. In France, kidney transplants are mainly from deceased donors or from living donors. Kidney transplantation is a scheduled surgery when the transplant is from a living donor, and an emergency when the transplant is from a deceased donor. The surgical technique is standardized and consists of suturing the artery and vein of the transplant onto the recipient's iliac vessels and the ureter in the bladder, through an ilio-inguinal incision. The average survival time of a transplant is 10 years and some patients may receive 1, 2, 3 or more kidney transplants in succession during their lifetime.

INTRODUCTION: Oncocytomas are primitive kidney tumours, considered benign but their evolution is not fully established. The local progression is generally admitted but few data explain what makes a oncocytoma to grow more or less quickly. The objective of our study is to analyse the evolution of followed renal oncocytomas after histologic confirmation and to identify factors that can influence their growth. MATERIAL AND METHODS: This is a retrospective study in two centers (North Hospital and Hospital of the Conception of Marseille). All patients with renal oncocytoma diagnosed with percutaneous biopsy from September 2010 to April 2016 and followed for more than one year were included. Epidemiological, histological, and morphological data were collected at diagnosis, during follow-up and in case of strategy change (intervention). Statistical analysis of factors influencing oncocytomes growth was based on the Pearson correlation test. RESULTS: Fifty-three patients were included. The median age for diagnosis was 65 years [39-85]. The sex ratio H/F was 6/5. The median follow-up was 34 months [12-180]. The average diagnosis size was 29 mm [12-90]. Thirteen patients (25%) were treated secondarily, including 70% by conservative treatment. The average growth was 0.25 (±0.23) cm/yr. The patients treated were younger and had a higher growth rate than the untreated (0.48±0.23cm/yr versus 0.18±0.18cm/yr, P<0,001). According to Pearson's analysis, there was a positive linear relationship (R=0.27, P=0.047) between velocity and initial size and a negative linear relationship (ρ=-0.44, P<0.001) between velocity and age at diagnosis. So tumor growth was faster if the patients were young and the tumor voluminous at diagnosis. DISCUSSION: Rapid growth often leads to a cessation of surveillance in favour of an intervention strategy. For young patients, conservative treatment (partiel nephrectomy or ablative treatment) in the medium term is likely to be preferred, but for elderly patients or with important comorbidities follow-up is an alternative to an invasive attitude.

INTRODUCTION: Living donor kidney transplants give the best results in term of renal function and are the principal solutions for the transplant shortage. However, donors selection and kidney function evaluation after surgery are essential. The objective of this study was to evaluate the prevalence and to identify the predictive factors of chronic renal failure for the donor, after living donor nephrectomy. MATERIALS AND METHODS: It was a retrospective and monocentric study, including all the patients who underwent a living donor nephrectomy from 2007 to 2015 at the hospital of the Conception in Marseille. The primary study endpoint was renal function mesured by the glomerular filtration rate (GFR in mL/min) at 1 year and 5 years after surgery. The identification of moderate kidney failure predictive factors was achieved by an univariate and a multivariate analysis under Cox model. RESULTS: Ninety-one patients were included. There was 40,7 % of men and media nage was 49 years (21; 70). Median pre-operative GFR was 94mL/min (67; 160). Median follow-up was 24 months (1; 120). Post operative GFR at 1 month, 1 year and 5 years was respectively 63mL/min (33; 90), 65mL/min (38; 107) and 67mL/min (56; 126) ans significantly lower than pre operative GFR (respectively P<0,001, P<0,001 et P=0,005). The prevalence of moderate kidney failure at 1 month, 1 year and 5 years was respectively 43,1 %, 33,3 % ans 25 %. In univariate and multivariate analysis, the only parametre significantly associated with a 1 year GFR>60mL/min wasp re operative GFR>90mL/min OR 3,61 IC95 % (1,27; 10,28) P=0,02. CONCLUSION: Living donor nephrectomy leads to an important medium to long term loss of renal function. Donors with pre operative GFR<90mL/min should benefit from a rigorous supervision and nephrological care. LEVEL OF EVIDENCE: 3.

OBJECTIVE: The objective of our study was to evaluate, in a review of the literature, the impact of diagnostic ureteroscopy before total nephroureterectomy (NUT) on the risk of bladder recurrence. METHODS: We conducted a literature review in the Pubmed database in March 2018. Initial research identified 45 publications. Following full text screening, 9 studies were finally included, with a total of 1041 NUT with URS prior versus 2909 NUT alone. The primary endpoint was bladder recurrence. Secondary objectives were specific survival and overall survival. RESULTS: Bladder recurrence was reported in the 9 studies included. Diagnostic ureteroscopy was significantly associated with an increased risk of post-NUT bladder recurrence (HZ 1.42 [1.29-1.56], P<0.01). The specific survival and overall survival at 5 years, were reported in respectively 4 and 2 studies. There was no impact of the pre-NUT diagnostic URS on the specific survival (HZ 0.75 [0.54-1.03], P=0.08) or post-NUT overall survival (HZ 1.15 [0.68-1.96], P=0.59). CONCLUSION: The URS diagnostic before NUT for TVEUS is associated with a significant increase in the risk of postoperative bladder recurrence.

INTRODUCTION: Military people are inapt for presence of urinary stones. In this specific population, the treatment of stones is even more aggressive than for the general population without recommendation. The final decision about aptitude is the responsibility of the military doctor. Whereas, ureteroscopy has its place there and must done by any urologist. METHODS: The purpose of this study was to estimate the results of treatments by ureteroscopy in this population. Success was defined by the complete absence of fragment visualized in the imaging of control operating comment and so the end of the inaptitude time. RESULTS: Between 2009 and 2016, forty-two were treated for ureteral or renal calculi. The population comprises of 93% men, 35 years old on average. The stones were mainly multiple (more 2) and the medium size is 5mm; sixteen (42.9%) was at the left and eight (19%) was bilateral. In 78.8% (78) of the cases there was a stone in renal position whose 50% (39) still at the lower calyx. In total, 5% of the patients were stone-free in 2 sessions on average. The average deadline of inaptitude of the initial consultation in the resumption of work was of 6 months. In 4% of the cases there was a complication operating rank 4. CONCLUSION: This study confirms the feasibility, the weak harmlessness of ureteroscopy and the lesser deadline of inaptitude. Every urologist can treat this specific population. The patient must be informed and accept the treatment because of excluding referential. LEVEL OF EVIDENCE: 4.

INTRODUCTION: The REVELA13 observatory is a unique epidemiological tool listing the new cases of kidney tumors, bladder tumors and acute leukaemias in the Bouches-du-Rhône county (France). Aim was to exploit for the first time data from this observatory regarding new cases of bladder tumors≥T1 in women from 2012 to 2014. MATERIALS: This epidemiological study was observational and descriptive. Fifteen non-nominative variables from the REVELA13 database were analyzed in order to describe the clinical and pathological characteristics of the incident cases as well as their spatial and temporal distribution. The incidence rates expressed in new cases per year per 100000 inhabitants were standardized on the world age, calculated with 95 % confidence intervals and compared to national estimates for the same period. RESULTS: Incident bladder tumor cases were recorded in 291 women, corresponding to a standardized incidence on the world age of 3.85 [3.32-4.37] new cases per year per 100,000 population, 54 % higher than the national estimates of 2012 and 2015. Median age of diagnostic was 75.9 years. Sex ratio was 19.41 % (W/M). Tumors were predominantly non-muscle-invasive (52 %), high grade (69 %) and without associated carcinoma in situ (Cis) (49 %). The two most affected territories were Marseille and Aubagne-La Ciotat. CONCLUSION: The REVELA13 observatory has improved our epidemiological knowledge on female bladder tumors in Bouches-du-Rhône county and highlighted a local over incidence. LEVEL OF EVIDENCE: 3.

PURPOSE: To report oncological outcomes of patients with prostate cancer undergoing active surveillance according to SURACAP criteria. METHODS: This multicentric study included patients who were initially treated with active surveillance for localized prostate cancer according to the SURACAP criteria. The duration of active surveillance as well as the causes of discontinuing the protocol and the definitive pathological results of patients who further underwent radical prostatectomy were retrospectively evaluated. The predictors of discontinuing active surveillance were assessed using a univariable Cox Model. In addition, the predictive value of initial MRI was assessed for patients who performed such imagery. RESULTS: Between 2007 and 2013, 80 patients were included, with a median age of 64 years [47-74]. Median follow-up was 52.9 months [24-108]. At 5 years follow-up, 43.4% patients were still under surveillance. Among patients that underwent surgery, 17.8% had an extra-capsular extension. The risk of discontinuing was not significantly greater for patients with tumor size of 2 or 3mm versus 1mm (HR=0.9 [0.46-1.75], P=0.763), 2 positives cores versus 1 (HR=0.98 [0.48-2.02], P=0.967), T2a vs. T1c stage (HR=2.18 [0.77-6.18], P=0.133), increased PSA level (HR=1 [0.96-1.15], P=0.975) or the patient's age (HR=1 [0.93-1.16], P=0.966). Among the 50 patients who performed initial MRI, the results of such imagery was not significantly associated to the risk of discontinuing active surveillance MRI (HR=1.49 [0.63-3.52], P=0.36). CONCLUSION: Although this study reveals a high rate of release from active surveillance at 5 years, the rate of extra-capsular tumors reported in the group of patients that underwent surgery is among the lowest in literature.

OBJECTIVE: To assess the influence of vascular clamping and ischemia time on long-term post-operative renal function following partial nephrectomy (PN) for cancer in a solitary kidney. PATIENTS AND METHODS: This is a retrospective study including 259 patients managed by PN between 1979 and 2010 in 13 centers. Clamping use, technique choice (pedicular or parenchymal clamping), ischemia time, and peri-operative data were collected. Pre-operative and last follow-up glomerular filtration rates were compared. A multivariate analysis using a Cox model was performed to assess the impact of ischemia on post-operative chronic renal failure risk. RESULTS: Mean tumor size was 4.0±2.3cm and mean pre-operative glomerular filtration rate was 60.8±18.9mL/min. One hundred and six patients were managed with warm ischemia (40.9%) and 53 patients with cold ischemia (20.5%). Thirty patients (11.6%) have had a chronic kidney disease. In multivariate analysis, neither vascular clamping (P=0.44) nor warm ischemia time (P=0.1) were associated with a pejorative evolution of renal function. Pre-operative glomerular filtration rate (P<0.0001) and blood loss volume (P=0.02) were significant independent predictive factors of long-term renal failure. CONCLUSION: Renal function following PN in a solitary kidney seems to depend on non-reversible factors such as pre-operative glomerular filtration rate. Our findings minimize the role of vascular clamping and ischemia time, which were not significantly associated with chronic renal failure risk in our study. LEVEL OF EVIDENCE: 5.
