RESUMO
INTRODUCTION: Urolithiasis is a common chronic disease whose effect on patients' quality of life (QOL) is considerable but depends on the treatment received, differing between types of surgery. Intrarenal stones can be treated with different techniques: extracorporeal shock wave lithotripsy (ESWL), flexible ureteroscopy (fURS), and mini percutaneous nephrolithotomy (mini-PCNL), with proportional success and complication rates. The aim of this study was to qualitatively explore the impact of the different techniques on patients' QOL and understand their experiences of treatment choices. METHODS: Patients treated for medium-sized kidney stones (10-20mm in diameter) were interviewed in a semi-structured manner. The interview data were transcribed and analyzed by theme according to consolidated criteria for reporting qualitative research (COREQ) guidelines. RESULTS: Data saturation was achieved after interviewing 15 patients. The mean interview time was 34min (standard deviation (SD), 6.8min). The mean patient age was 54 years (SD, 9.5 years). Eight patients underwent ESWL, 10 were treated with fURS, and 8 underwent mini-PCNL. Twenty-seven subthemes were coded and regrouped into eight major themes, namely: no sense of choice in the decision-making process for eleven patients; extremely negative experiences of double-J stents for fourteen patients; concern about the risk of recurrence or treatment failure for thirteen patients; complicated hygiene and dietary recommendations for nine patients; technique-dependent postoperative outcomes; relatively well-tolerated operations for thirteen patients; a poor experience of sick leave, often because of a double-J stent; different views regarding future operations. In fact, a third of patients would choose the most effective treatment, a third would choose the simplest procedure and the last third would trust their urologist. Patients' experiences of these operations are variable. CONCLUSION: Urologists must support their patients by presenting the different treatment options with clear, appropriate, and unbiased information. This should ensure patients take part in treatment decisions as part of a personalized treatment plan.

INTRODUCTION: Urological emergencies represent 7% of admissions, 29% of which are acute urine retention. We report the first results of a protocol evaluating a new device in case of failure of self-catheterization, replacing a permanent catheter: the urethral device EXIME®. METHOD: Intention-to-treat study on the feasibility of inserting the EXIME® prosthesis in a day hospital after simple urethral gel instillation in men with urine retention. EXIME® was proposed to all patients after failure of Foley catheter removal and refusal or inability to learn self-catheterization. The protocol was referenced (NCT04218942) after obtaining the agreement of the committee for the protection of individuals. RESULTS: Among 278 patients admitted for a trial of Foley catheter removal, 15 patients with failed voiding resumption and refusal or failure of self-catheterization were offered the prosthesis. The median age was 73 years with a median retention volume of 700mL. The median prostatic volume was 60g. Fourteen patients had their prosthesis inserted in good conditions of comfort for the practitioner and the patient. One failed placement was noted. The difficulty of insertion was estimated by the practitioner at 0 on median (VAS from 0 to 10), and for its removal at 0. The pain during the insertion of the device was evaluated by the patients at 2.00 and for the removal at 0 (VAS from 0 to 10). 6 patients had satisfactory voiding recovery at D0. DISCUSSION: We proposed the placement of EXIME to patients who had failed the trial of Foley removal and were unable and/or unwilling to self-catheterize. These were patients with poor bladder contractility and a high risk of retention recurrence. Despite this mixed result, the simplicity of the device and the comfortable expectation of an endoscopic procedure seem promising. CONCLUSION: Insertion and retrieval of EXIME®prostatic prosthesis were easy and well tolerated in our population. Insertion failed in one patient. A comparative prospective study with self catheterization is necessary to determine its effectiveness.

INTRODUCTION: Preoperative information is a key to adherence to treatment for the patients, but may be misunderstood because of its density and complexity. The aim of this study was to assess comprehension and satisfaction of patients about preoperative information of benign prostatic hyperplasia (BPH) surgery. Factors influencing patient understanding were also studied. PATIENTS AND METHODS: It was a monocentric study on questionnaires including every patients planned for BPH surgery, whatever the surgical technique. A survey was sent at patient's home after the preoperative consultation. RESULTS: One hundred and six of 210 patients (50,5 %) returned the questionnaire. 38,68 % (n=41) found the quality of information excellent (9 or 10 out of 10), and 45,28 % (n=48) found the quality of information good (7 or 8 out of 10). The main recalled complications were retrograde ejaculation (39.6 %, n=42/106), and bleeding (29,2 %, n=31/106). 57.6 % of patients (n=61) remembered receiving the written information sheet of the French Association of Urology. 5.7 % (n=6) hesitated having the procedure. Only patient's age was significantly associated with difference of comprehension (p<0.005). CONCLUSION: Information given before a BPH surgery seems satisfactory although it was poorly understood, notably about complications. Providing complete oral information, insisting on complications, and giving the written information sheet are essential for a good doctor-patient relationship and a forensic serenity.

INTRODUCTION: Several enhanced recovery protocols after surgery showed a benefit for postoperative recovery and reduction of hospital lengths of stay. Very few studies evaluated patient's satisfaction about these enhanced recovery protocols. The aim of this study was to evaluate patient's satisfaction about our enhanced recovery protocol for robotic-assisted partial nephrectomy (RAPN). METHODS: A validated survey EORTC In PATSAT32 with a specific questionnaire about protocol was sent to the first patients included in the enhanced recovery protocol for RAPN. The survey was sent after the postoperative consultation at postoperative day 30. Responses were anonymous. Satisfaction's scores for EORTC questionnaire were calculated for each dimension with Likert's method. Scores were transformed linearly into a scale ranging from 0 to 100, where 100 represent the highest level of care satisfaction (EORTC method). RESULTS: A total of 21 patients (50%) returned the completed questionnaire. The overall satisfaction score was 75.1% (37.3; 100) in the EORTC survey. In total, 71.4% of patients (n=15) were satisfied with the discharge at postoperative day 2 (POD2) and 5 patients (23.8%) found this premature. None of the patients had a negative impression on the clinical pathway. The average overall evaluation on the protocol by patients, on a satisfaction scale of 1 to 10 was 8.9/10. CONCLUSION: In this study, patients included in the enhanced recovery protocol after RAPN were very satisfied with their pre-, per- and postoperative care. Given patients satisfaction, reduction of LOS, patient's safety and the medicoeconomic advantage, these enhanced recovery protocol have become a priority to develop and evaluate. More large studies are needed to assess the patient's experience with these clinical pathways. LEVEL OF EVIDENCE: 4.

AIMS: The objective of this study was to assess the effectiveness and the complications rate following continent cutaneous channels (CCC) procedures, at short and medium term follow-up (FU). MATERIALS & METHODS: A continuous retrospective case series (2008-2018): all patients who have undergone a CCC for neurogenic bladder were included in our department. The primary outcome was the effectiveness of CCC defined by the status of catheterizability (by the patient or a care-giver), continence of the tube, and absence of reintervention at 3 and 12 months FU. The secondary outcome was the prevalence of postoperative complications at 3 and 12 months FU. RESULTS: Fifty-three patients were included during the study period in our department. Median follow up was 3,3 years (1.5-6.1). The overall effectiveness of CCC was 67.9% (n=36/53) at 3 months FU and 45,3% (n=24) at 12 months FU. The global rate of complications was 60.4% (n=32/53) at 3 months, and 73.6% (n=39/73) at 12 months FU. The statistical analysis showed no statistical differences on efficacy and complications in the different subgroups of CCC. CONCLUSIONS: In the current series, the effectiveness and the complications rates following CCC were comparable across the procedure types. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To evaluate long-term sexual function results following plication surgery for the correction of penile curvature using patient questionnaires. METHODS: We performed a single-center, retrospective study in a cohort of patients with Peyronie's disease or congenital penile curvature. All patients who underwent plication surgery on the convex aspect using the Nesbit, Yachia or diamond-shaped techniques were included. At a mean 34 months after the interventions, the patients were asked to respond to the IIEF5 questionnaire and a 19-item questionnaire. RESULTS: Forty-six patients operated for Peyronie's disease and 12 for congenital curvature (total: 58) were included in the study. The questionnaire response rate was 69% (40/58). The shortened penis bothered 47.5% of patients in their sexuality at least regularly. Involuntary exit from the vagina occurred for 35% of the patients in at least one out of two sexual intercourse sessions. Postoperative sexual life was as good as or better than preoperative sexual life for 35% of the patients and 95% stated that they could achieve erection at least sometimes, in coherence with the mean IIEF5 result of 19.3/25. CONCLUSION: Our study suggests that even when successful, a relatively high rate of patients may be unsatisfied with the results of plication surgery, and there may be a relatively low rate of maintenance or improvement of postoperative sexual life. Furthermore, our in-house questionnaire, although not validated, shed light on how bothersome the loss of penis length is in postoperative sexuality, an aspect the IIEF5 and its sole evaluation of erectile quality cannot detect.

OBJECTIVE: To evaluate the performance of the Allium ureteral stent in the management of patients initially treated with double J stents for the long-term treatment of stenoses. MATERIALS AND METHODS: We performed a retrospective multicenter study involving 36 patients who received 37 Allium ureteral stents (metallic 24 Fr) between September 2011 and January 2015 in one of three French teaching hospital centers. The mean age of the patients was 63.8 years (min-max: 33-88 years) and most were women (70%). Of these patients, 5.6% had ureteral fistulae and 94.4% stenoses. Mean stenosis length was 4.15cm (min-max: 0.5-12cm). All analyses were two-tailed with an alpha risk of 0.05. Statistical significance was set at P<0.05. Results were expressed as hazard ratios (HR) with 95% confidence intervals and P-values. RESULTS: During the follow-up period, 37% of the stents were removed due to migration (complication occurring in 18.9% of the studied population), infection (10.8%) or intolerance (8.1%). The other stents were removed after 1 year. Clinical effectiveness, defined as a lack of stenosis or fistula recurrence, was 52.8% after a mean follow-up of 7.1 months. CONCLUSION: Clinically effective in more than 50% of cases, the Allium ureteral stent appears to be an alternative to indwelling double J stents. LEVEL OF EVIDENCE: 4.

MAIN OBJECTIVE: To identify hospitalizations directly related to a complication occurring within 30 days following a transrectal prostate biopsy (PBP). SECONDARY OBJECTIVES: Overall hospitalization rates, mortality rates, potential predisposing factors for complications. PATIENTS AND METHODS: Single-center study including all patients who underwent PBP between January 2005 and January 2012. Any hospitalization occurring within 30 days of the PBP for urgent motive was considered potentially attributable to biopsy. We identified the reason for hospitalization with direct complications (urinary infection or fever, rectal bleeding, bladder caillotage, retention) and indirect (underlying comorbidities decompensation) of the biopsy. The contributing factors were anticoagulant or antiplatelet treatment well as waning immunity factors (corticosteroid therapy, HIV, chemotherapy or immunodulateur). RESULTS: Among 2715 men who underwent PBP, there were 120 (4.4%) hospitalizations including 28 (1.03%) caused by the biopsy. Twenty-five (0.92%) were related to a direct complication of biopsy: 14 (56%) for urinary tract infection or fever including 1 hospitalization in intensive care, 5 (20%) for rectal bleeding which required several transfusions 1, 10 (40%) urinary retention and 3 (0.11%) for an indirect complication (2 coronary syndromes and 1 respiratory failure). Several direct complications were associated in 3 cases. Only two hospitalizations associated with rectal bleeding were taking an antiplatelet or anticoagulant. There was no association between hospitalization for urinary tract infections and a decreased immune status. The first death observed in our study occurred at D31 of pulmonary embolism (advanced metastatic patient with bladder cancer). Twenty (60.6%) patients urgently hospitalized did not have prostate cancer. CONCLUSIONS: Within this large sample of patients the overall rate of hospitalization due to the realization of a PBP was 1%. It has not been found predictive of complications leading to hospitalization. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To evaluate oncologic and functional outcomes after percutaneous cryoablation (PCA) for renal masses based on our single center experience. PATIENTS AND METHODS: We retrospectively identified 26 patients who underwent PCA for 28 tumors between November 2006 and June 2011. Patient's demographics and baseline clinical characteristics, tumor features, perioperative information, and postoperative outcomes we rerecorded. A biopsy was performed systematically before each procedure. Control imaging was obtained at 1, 3, 6 and 12 months, and yearly thereafter. Oncological outcomes were determined by radiographic evidence of tumor recurrence, which was defined by contrast enhancement at the cryoablation site on control imaging at M3. RESULTS: Patients had mean age of 70.1 years, mean Charlson comorbidity index (CCI) and body mass index) were 6 and 29 kg/m(2) respectively. There were 11 kidney transplants, including 4 solitary. Mean tumor size was 29.5mm and was represented mainly by clear cell renal cell carcinomas (16/28), endophytic (17/28) and midkidney (14/28) (±9.8). Twenty-five cryoablations were performed percutaneously by two lumbotomy. Mean clearance preoperative MDRD was 66,1 mL/min. Mean length of stay was 3.3 days (±2.2). Intraoperative complications consisted of 2 pneumothorax and 6 minor complications postoperative (Clavien≤2). There were no major complications. Mean follow-up was 27.5 months (±15.7), MDRD clearance distance was 61.9 mL/min. Overall survival and disease-specific survival was 100%, while the recurrence-free survival was 78.6% (5 recurrences and 1 failure treatment). CONCLUSION: The percutaneous cryoablation provides a safe and oncologically to extirpative surgery for renal masses in patients with significant medical comorbidities. LEVEL OF EVIDENCE: 5.

INTRODUCTION: The use of transplants from extended criteria donors increases the number of urological complications after renal transplantation. Two different anastomosis techniques used to restore urinary continuity are compared in this study. PATIENTS AND METHODS: Retrospective study, bi-center over a period of 5 years. One hundred and seventy six patients operated at Hospices Civils de Lyon benefited from ureteroneocystostomy according to De Campos-Freire (group 1) and 167 patients operated at the Necker Hospital in Paris had a pyelo-ureterostomy (group 2). The various urological complications (fistulas, strictures, seromas, haematomas and vesico-ureteric reflux) and their care were compared. Risk factors were sought. RESULTS: The waiting time before transplantation was longer in group 2 than in group 1 (51 and 33.84 months) as the percentage of anuric patients (52.9 % against 32.9 %) (P<0.001). The cold ischemic time was shorter in group 1 (939.3minutes on average against 1325.3minutes for group 2) (P<0.001). A double J stent was put in place in 97.6 % of cases in group 2 against 84.2 % for group 1 (P<0.001). We did not find any significant difference in the occurrence of stenosis and fistulas (major complications) between the 2 groups. There were more minor complications (hematoma, seroma and vesico-ureteric reflux) in group 1 (P=0.033). There was a difference in the treatment of these complications, especially stenosis (P=0.024) with a significantly more conservative approach in group 2. Multivariate analysis found anuria, sex of recipients and donor age as independent risk factors in the onset of complications and the double J stent as a protective factor. CONCLUSION: This study does not demonstrate the superiority of a urinary anastomosis technique. The establishment of a double J stent reduces the risk of complications. Analysis of risk factors allows to propose a decision tree to guide the surgical strategy, particularly in the population of anuric recipients. LEVEL OF EVIDENCE: 5.

INTRODUCTION: Stress urinary incontinence (SUI) is a degradation of the quality of life factor in the consequences of radical prostatectomy. Artificial urinary sphincter (AUS) is the standard treatment. Screening and preoperative treatment of anastomotic strictures (AS) is an essential step for the success of the intervention. The objective of the study was to assess the impact of AS on the results of AUA. METHODS: We retrospectively studied 147 AUS settlements from 2005 to 2013 in the urology department of the Centre Hospitalier Lyon by three operators. The demographic characteristics, the irradiation history, the severity of incontinence, the complications of AUS, the continence rate and the postoperative satisfaction were collected. Wilcoxon statistical tests and Fischer and a Kaplan-Meier curve were used to compare the two control groups and AS. Logistic regression analysis looked for predictors of surgical reintervention. RESULTS: Of the 147 patients included, 24 (16.3%) had a history of AS. Of these, 21 (87.5%) were treated with endoscopic urethrotomy. Patients in the AS group had more severe incontinence (P<0.05) than in the control group. Explantation rates, recurrence of incontinence and reoperation was 12.5%, 8.3% and 33.3% in the AS group against 4.9%, 15.4% and 27.6% in the control group. In logistic regression, history of AS has not been found as reoperation risk factor. Continents and satisfied patients rate were 77.8% and 76.5%, respectively in the AS group against 91.1% and 81.1% in the control group. CONCLUSION: The history of AS does not appear to be predictive of poor outcome after implementation of a AUS. Larger cohort studies are needed to confirm these results. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To assess preoperative renal tumor biopsy (RTB) accuracy. MATERIALS AND METHODS: As part of the prospective NEPHRON study, data from 1,237 renal tumors were collected, including the use and results of RTB and final histology following nephrectomy. During the 6 months period of inclusion, 130 preoperative biopsies were performed. We used the kappa coefficient of the McNemar test to determine the concordance between the biopsy and the nephrectomy specimen (NS) regarding four parameters: malignant/benign status, histological subtype, Fuhrman grade and microscopic necrosis. RESULTS: Preoperative biopsies were performed in 9.7 and 11.4 % of the 667 radical and 570 partial nephrectomies, respectively. Tumor biopsy was inconclusive in 7.7 % of the cases. In 117 cases, a comparison between RTB and NS was available. Benign tumors accounted for three (2.6 %) and five (4.3 %) of the RTB and NS, respectively (κ = 0.769, good). With seven (6 %) discordant results in terms of histological subtype characterization between RTB and final pathology, RTB accuracy was considered excellent (κ = 0.882). In 33 cases (31.7 %), Fuhrman grade was underestimated at biopsy resulting in an intermediate concordance level (κ = 0.498). Tumor microscopic necrosis was identified in 12 RTB (10.4 %) versus 33 NS (28.4 %) (κ = 0.357, poor). CONCLUSIONS: RTB provides good to excellent diagnostic performance for discriminating malignancy and tumor histological subtype. However, its performance is intermediate or even poor when considering prognostic criteria like Fuhrman grade or microscopic necrosis. Thus, this possible inaccuracy should be taken into consideration when using RTB for accurate guidance of treatment strategy.

OBJECTIVES: To evaluate the consequences of laparoscopic nephrectomy with vaginal extraction on sexual quality of life. METHODS: Sixteen patients (mean age: 53.8 years) who underwent laparoscopic nephrectomy with vaginal extraction between September 2010 and February 2014 were included in this monocentric prospective study. All patients underwent a preoperative gynecological examination to evaluate the feasibility of vaginal extraction. The sexual function of the patients was evaluated using the French version of the Female Sexual Function Index (FSFI). The patients completed an initial FSFI preoperatively then another postoperatively after the resumption of sexual activities. RESULTS: The mean hospital stay was 2.2 days (0-5 days). No postoperative complications were observed except for one case of bleeding at the vaginal incision 4 days after surgery, resolved with a single suture under local anesthesia. Fifteen patients (94%) completed both the pre- and postoperative FSFIs. Three patients were sexually inactive and one was a virgin. The pre- and postoperative mean FSFI overall scores were 24.2 and 24.3 respectively (p=0.39). Scores were comparable in all six of the domains assessed by the questionnaire. Particularly, the pre- and postoperative scores for satisfaction were 4.5 and 4.4 respectively. No increase in dyspareunia was observed after surgery, nor was it more difficult for our patients to reach orgasm after the intervention. No statistically significant differences were observed between the pre- and postoperative FSFI scores. CONCLUSIONS: Although preliminary, our results suggest that laparoscopic nephrectomy with vaginal extraction has no effect on the sexual quality of life of patients.

AIM: To evaluate the performance of urinary PCA3 test to predict prostate biopsy outcome in a large French cohort. PATIENTS AND METHODS: A urine sample was prospectively obtained in 1015 patients undergoing prostate biopsies to determine the PCA3 score. The predictive value of PCA3 was explored using receiver operating characteristic curve analysis (ROC), multivariable logistic regression analysis and decision curve analysis. RESULTS: The median PCA3 score was significantly higher in patients with positive biopsies. The PCA3 score AUC was 0.76 (0.73-0.79), significantly higher than that of PSA (0.55; 0.51-0.58). At the cut-off of 35, sensitivity was 68 %, specificity 71 %, positive and negative predictive values 67 % and 71 %, and accuracy 69 %. Using multivariate analysis, PCA3 score appeared as an independent predictor of biopsy outcome and its addition to a base model including usual clinico-biological parameters resulted in a significant increase in predictive accuracy. At the cut-off of 20, about 1/2 of the eventual useless biopsies would have been avoided while ignoring 7 % of cancers with Gleason score ≥ 7. PCA3 score did not correlate to Gleason score but correlated to tumor volume (proportion of invaded cores). CONCLUSION: Urinary PCA3 is a useful test with high diagnostic performance for early prostate cancer diagnosis. Its correlation with cancer aggressiveness seems rather represented by a link to prostate volume than Gleason score.

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.

PURPOSE: Similar to prostate-specific antigen (PSA) density, PCA3 density (PCA3D: ratio of urinary PCA3 score/prostate volume) can be calculated, but whether it can be an aid to decide biopsy in patients at risk of prostate cancer (PCa) is uncertain. The objective was to demonstrate that PCA3D provides better specificity than PCA3 in predicting initial prostate biopsy outcome. METHODS: Serum and urine samples were obtained from 595 consecutive patients scheduled for initial prostate biopsy. The urinary PCA3 test was performed before biopsy. Additional measures were prostate volume, PSA density (PSAD) and PCA3D. Multivariate logistic regression models including baseline characteristics and the markers were evaluated. The presumed net benefit was assessed through decision curve analyses. RESULTS: PSAD and PCA3D performed better than PSA and PCA3 score, respectively. PCA3D provided the best specificity (76 %). The best calculated cutoff for PCA3D was 1. The risk of positive biopsy significantly increased to 70 % if PCA3D ≥ 1 versus 29 % if PCA3D was <1. Using a cutoff at 0.5 for PCA3D, biopsies could have been avoided in up to 52 % of the patients without PCa while missing 15 % of any PCa and 10 % of PCa with Gleason score ≥7. Decision curve analyses showed that PSAD was the best predictor of Gleason score at biopsy while PCA3D best predicted the proportion of invaded cores. CONCLUSIONS: PCA3D showed a significant increase in specificity when compared with PSA, PSAD and PCA3. PCA3D can be considered an easy-to-use mini-nomogram with a 70 % risk of positive initial biopsy when PCA3D > 1, i.e., PCA3 score > prostate volume.

OBJECTIVE: To evaluate the feasibility and morbidity of laparoscopic nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPK). PATIENTS AND METHOD: This is a retrospective multi-centre study (University Hospitals of Lyons, Toulouse, Nantes and Rennes). Sixty-eight patients who had undergone laparoscopic nephrectomy for polycystic kidney disease between November 1999 and May 2009 were included. This involved unilateral nephrectomy 64 cases, one-stage bilateral in one case and two-stage bilateral in three cases. RESULTS: The mean operating time was 218±74min (100-420) Conversion was necessary in 7 cases. The mean weight of the removed kidney was 1291±646g (240-3400). We regret to report 20 postoperative complications, including one death on postoperative day 50, following an abscess in the renal pelvis, 6 retroperitoneal haemoatomas and 5 arteriovenous fistula thromboses. Postoperative analgesia involved PCA treatment with morphine for a mean period of 1.59±0.8 days (0.5-4). The mean length of hospital stay was 8.3±6.1 days (3-50). CONCLUSION: This study shows the feasibility of the laparoscopic approach for nephrectomy in ADPK. This procedure should be performed by experienced laparoscopic surgeons. Indeed, the complication rate is moderate but there is still a risk of severe complications. LEVEL OF EVIDENCE: 5.

PURPOSE: To study the feasibility and to present results of laparoscopic nephrectomy with vaginal extraction in overweight or obese patients. PATIENTS AND METHODS: Three patients having BMI>28 kg/m(2) underwent surgery. Median age was 56 years, median BMI was 44.4. Medical history included for the three patients type 2 diabetes mellitus and arterial hypertension. Two of the three patients were multiparous, one was nulliparous. Patients underwent standard laparoscopic nephrectomy with vaginal extraction of the specimen through a short incision of the posterior vaginal fornix. Feeding was normal on the first operating day. No morphine was prescribed during hospitalization stay. RESULTS: No intraoperative complication occurred. Mean procedure time was 224 min. Mean blood loss was 140 mL. Postoperative period was uneventful and walking was normal on the first operating day. Hospitalization stays were 2, 3 and 5 days. One month follow up found no complication including normal sexual activity. CONCLUSION: Laparoscopic nephrectomy with vaginal extraction is a feasible technique in obese or overweight patients. Wound morbidity (infection, hernia) is reduced due to the small abdominal incisions.

INTRODUCTION: Determinate if the adjunction of PCA3 score and/or prostatic MRI can improve the selection of the patients who have an indication of first prostate biopsy. PATIENTS AND METHODS: Multiparametric prostatic MRI and PCA3 score were made before biopsy to men scheduled for initial prostate biopsy for abnormal digital rectal examination and/or PSA superior to 4 ng/mL. T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced imaging looked for suspect target classified on a scale of four. It was a prospective, single centre study. The diagnostic accuracy of PCA3 score and MRI was to evaluate in comparison with biopsy results. RESULTS: Sixty-eight patients were included, median PSA was 5.2 ng/mL (3.2-28). Negative predictive value (NPV) of MRI score 0, 1 and 2 were respectively 80%, 43% and 69%. Positive predictive value (PPV) of MRI score 3 and 4 were 50% and 81%. The PCA3 cutoff with best accuracy was 21 (Se: 0.91; Sp: 0.50). Only one patient with positive biopsy (0.5mm of Gleason score 3+3) had negative MRI and PCA3 inferior to 21. CONCLUSION: MRI and PCA3 score in association allowed, in this study, to consider reduction of unnecessary initial biopsy without ignoring potential aggressive tumor.
