Impact of Enhanced Recovery after Surgery® Protocol Compliance on Length of Stay, Bowel Recovery and Complications after Radical Cystectomy.

BACKGROUND: Despite existing standardized surgical techniques and the development of new perioperative care protocols, radical cystectomy (RC) morbidity remains a serious challenge for urologists. Postoperative ileus (POI) is one of the most common postoperative complications, often leading to a longer length of stay (LOS). The aim of our study was to assess the impact of compliance to the Enhanced Recovery After Surgery (ERAS®) protocol on bowel recovery, 30-day complications and LOS after RC for bladder cancer (BC). METHODS: Data from consecutive patients undergoing RC for BC within an ERAS® dedicated protocol were analyzed. Exclusion criteria were urinary diversion other than ileal conduit and palliative RC. Patients were divided into two groups according to their compliance (A: low-compliance and B: high-compliance). ERAS® compliance was extracted from the ERAS® Interactive Audit System (EIAS) database. Postoperative complications were prospectively recorded by a dedicated study nurse 30 days after RC. POI was defined as the placement of a nasogastric tube. Logistic regression analysis was used to identify predictors of 30-day complications and POI. RESULTS: After considering the exclusion criteria, 108 patients were included for the final analysis. The median global compliance to the ERAS® protocol was 61%. A total of 78 (72%) patients had a compliance <65% (group A), while the remaining 30 (28%) had a compliance >65% (group B). No significant differences were found among the two groups regarding the 30-day complication rate (86% in group A versus 73% in group B, p = 0.82) and LOS (14 days in group A versus 15 days in group B, p = 0.82). The time to stool was significantly shorter in group B (4 days versus 6 days, p = 0.02), and the time to tolerate solid food was slightly faster in group B but not significant (8 versus 7 days, p = 0.23). The POI rate was significantly lower in patients with a higher ERAS® compliance (20% versus 46%, p = 0.01). A multivariate analysis showed that ERAS® compliance was not significantly associated with 30-day total complications. However, a lower compliance to the ERAS® protocol and age > 75 years were significant independent predictors of POI. CONCLUSIONS: Our study provides further evidence to support the beneficial effect of the ERAS® protocol in patients undergoing RC, particularly in terms of facilitating a faster recovery of bowel function and preventing POI. Future research should focus on investigating novel approaches and interventions to improve compliance with the ERAS® protocol. This may involve patient education, multidisciplinary teamwork, and continuous quality improvement initiatives.

ERAS® protocol improves survival after radical cystectomy: A single-center cohort study.

INTRODUCTION: To evaluate Enhanced recovery after surgery (ERAS®) protocol on oncological outcomes for patients treated with radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). METHODS: A prospectively maintained single-institutional database comprising 160 consecutive UCB patients who underwent open RC from 2012 to 2020 was analyzed. Patients receiving chemotherapy and those with a urinary diversion other than ileal conduit were excluded. Patients were divided into two groups according to the perioperative management (ERAS® and pre-ERAS®). The study aimed to evaluate the impact of the ERAS® protocol on survival at five years after surgery using a Kaplan-Meier log-rank test. A multivariable Cox proportional hazards model was used to identify prognostic factors for cancer-specific (CSS) and overall survival (OS). RESULTS: Of the 107 patients considered for the final analysis, 74 (69%) were included in the ERAS® group. Median follow-up for patients alive at last follow-up was 28 months (interquartile range [IQR] 12-48). Five-years CSS rate was 74% for ERAS® patients, compared to 48% for the control population (P = 0.02), while 5-years OS was 31% higher in the ERAS® (67% vs. 36%, P = .003). In the multivariable analysis, ERAS® protocol and tumor stage were independent factors of CSS, while ERAS®, tumor stage so as total blood loss were independent factors for OS. DISCUSSION: A dedicated ERAS® protocol for UCB patients treated with RC has a significant impact on survival. Reduction of stress after a major surgery and its potential improvement of perioperative patient's immunity may explain these data.

Reporting Radical Cystectomy Outcomes Following Implementation of Enhanced Recovery After Surgery Protocols: A Systematic Review and Individual Patient Data Meta-analysis.

CONTEXT: Enhanced Recovery After Surgery (ERAS) is a perioperative approach to managing surgical patients. The impact of ERAS on radical cystectomy (RC) outcomes remains understudied. OBJECTIVE: To review the literature regarding ERAS protocols and RC outcomes. The primary outcome was hospital length of stay (LOS). EVIDENCE ACQUISITION: A systematic review of the articles published from 1970 through 2018 was conducted. Individual patient data (IPD) were requested and a meta-analysis was performed. EVIDENCE SYNTHESIS: A total of 4197 articles were retrieved and 22 (reporting 4048 patients) were selected for the review. LOS followed by 30-d and that followed by 90-d complications were the most common endpoints. ERAS use was associated with reduced morbidity, quicker bowel recovery, and shorter LOS, without affecting mortality. IPD were obtained for 2077 patients from 11 studies. In multivariable models, LOS was associated with ERAS use (regression coefficient: -4.54 [95% confidence interval {CI}: -5.79 to -3.28] d with ERAS p < 0.001) and Charlson Comorbidity Index (+1.64 [1.38-1.90] d for each point increase, p < 0.001), and varied between hospitals (from -1.59 [-3.03 to -0.14] to +4.55 [1.89-7.21] d, p < 0.03). Individual ERAS components associated with shorter LOS included no nasogastric (NG) tube (-8.70 [-11.9 to -5.53] d, p < 0.001) and local anesthesia blocks compared with regional anesthesia (-3.29 [-6.31 to -0.27] d, p = 0.03). CONCLUSIONS: ERAS protocols were associated with reduced LOS and postoperative complication rate. Avoidance of NG tubes and use of local anesthesia blocks were significantly associated with reduced LOS. These findings reflect different components of recovery, which ERAS can optimize and further support documentation of the use of ERAS components when reporting RC outcomes. PATIENT SUMMARY: Use of enhanced recovery in patients undergoing surgery to remove the bladder is associated with fewer surgical complications and a shorter hospital stay. Avoidance of nasogastric tubes and use of local anesthesia after the operation were associated with a shorter length of stay.

Intramuscular Immunization Induces Antigen-specific Antibodies in Urine.

Towards the development of vaccines against urinary tract infections (UTI), we determined the ability of intramuscular (i.m.) immunization to result in antigen-specific antibodies in urine. As a model antigen/vaccine, levels of total and vaccine-specific antibodies were determined in urine as a spin-out study of a phase 1 trial. Non-muscle-invasive bladder cancer (NMIBC) patients at different risks of progression, undergoing intravesical bacillus Calmette-Guérin (BCG) immunotherapy or not, received an adjuvanted recombinant protein vaccine that resulted in high titers of vaccine-specific serum immunoglobulin G (IgG) in all patients, regardless of the risk group. Vaccine-specific IgG and immunoglobulin A (IgA) were detected in urine of half of the patients at low risk of progression NMIBC and in all the intermediary/high- (int/high) risk patients. Vaccine-specific IgG titers were correlated to total urinary IgG levels, the latter being higher in the int/high-risk patients. In contrast, vaccine-specific IgA did not correlate to urinary IgA levels. Furthermore, vaccine-specific antibodies were transiently increased by intravesical BCG instillations. Altogether, our data show that a standard i.m. immunization can effectively induce antigen-specific antibodies in urine, which, upon selection of optimal vaccine targets, may provide protection against UTI. Vaccine-specific IgG titers were dependent on conditions affecting total urinary IgG levels, while production of vaccine-specific IgA in situ might independently contribute to protection against infections in the bladder. PATIENT SUMMARY: Towards the development of vaccines able to protect against urinary tract infections, we examined the potential of the intramuscular vaccination using a model antigen. We found two types of specific antibodies in the urine, which together may locally contribute to protection against infections, thus supporting the use of such a standard immunization route.

[Myths and reality about immunonutrition in uro-oncology]. / Immunonutrition en uro-oncologie : entre mythe et réalité.

Postoperative morbidity remains a nightmare (although vivid), both for the patient and the surgeon. One phantasmagorical idea would be to give the patient a « magic potion ¼ preoperatively aiming at eliminating the risk of postoperative complication. The purpose of the present review is to summarize the current knowledge on the potential benefits of immunonutrition administered to urological cancers patients. After a brief summary on the role of immunity in cancer surveillance and treatment, the rationale about administrating oral nutritional supplements able to modulate the patient's immune system before cystectomy for bladder cancer will be highlighted.

La survenue de complications postopératoires représente un cauchemar (bien réel), tant pour le patient que pour son chirurgien. Dès lors, quoi de plus fantasmagorique que d'administrer une « potion magique ¼ au patient avant l'intervention pour éliminer ce risque ? Le but de cet article est de résumer l'état des connaissances actuelles concernant les bénéfices potentiels, liés à l'administration d'immunonutrition aux patients traités pour cancer urologique. Après un bref rappel du rôle de l'immunité dans la surveillance et le traitement uro-oncologique, le raisonnement en faveur d'une supplémentation orale pouvant moduler le système immunitaire du patient bénéficiant d'une cystectomie pour cancer sera mis en évidence.

[Local treatment in oligometastatic urological malignancies : evidence of wishful thinking ?] / Ablation du cancer primaire dans les néoplasies urologiques oligométastatiques : évidence ou vœux pieux ?

In the past, it was generally considered that the window of curability had been missed in metastatic solid cancers. At present, novel evidence suggests that oligometastatic cancer might be amenable to a multimodal curative treatment, including ablation of the primary tumour. In this article, we summarise the indications, the controversies and future perspectives of local treatment in oligometastatic urological malignancies.

Dans le passé, on considérait le plus souvent que la fenêtre de curabilité dans les cancers solides à un stade métastatique avait été manquée. De nouvelles évidences suggèrent à présent que la maladie à un stade oligométastatique est accessible, dans certains cas, à un traitement multimodal curatif, incluant l'ablation de la tumeur primaire. Dans cet article, nous résumons les indications, les controverses ainsi que les perspectives futures du traitement local dans les cancers oligométastatiques urologiques.

Initial single-centre Canadian experience with 18F-fluoromethylcholine positron emission tomography-computed tomography (18F-FCH PET/CT) for biochemical recurrence in prostate cancer patients initially treated with curative intent.

INTRODUCTION: We sought to determine predictive factors (patient and prostate-specific antigen [PSA] characteristics) for 18F-fluoromethylcholine positron emission tomography-computed tomography (18F-FCH PET/CT) positivity in the context of biochemical recurrence after local treatment of prostate cancer (PCa) with curative intent. METHODS: This is a retrospective study including 60 18F-FCH PET/CT scans of patients with biochemical recurrence after initial radical prostatectomy (RP), external beam radiation therapy (EBRT), or focal high-intensity focused ultrasound (HIFU) with curative intent. The results were compared to findings on magnetic resonance imaging (MRI), computed tomography (CT), bone scan (BS), and histological analysis when available. Univariate analysis was performed to correlate results with patient characteristics. RESULTS: Thirty-eight (63.3%) scans were positive, 17 (28.3%) negative, and 5 (8.3%) equivocal. Of the positive scans, 16 demonstrated local recurrence, 12 regional/distant lymph nodes, five bone metastasis, and five local and distant recurrences. Among the 22 PET/CTs showing metastasis, conventional imaging was performed in 16 patients (72.7%). Of these, it demonstrated the lesion(s) found on PET/CT in eight patients (50.0%), was negative in seven (43.8%), and equivocal in one (6.3%). The trigger PSA (p=0.04), prostate-specific antigen velocity (PSAV) (p=0.03), and prostate-specific antigen doubling time (PSADT) (p=0.046) were significantly different when comparing positive and negative scans. Patients with positive scans were more likely to have received EBRT initially (odds ratio [OR] 11.0, 95% confidence interval [CI] 2.2-55.3). A trigger PSA of 2.6 ng/mL had a sensitivity of 84% and specificity of 65% for a positive scan. PET/CT changed the clinical management plan in 17 patients (28.3%). CONCLUSIONS: 18F-FCH PET/CT demonstrates a high detection rate for local and distant recurrences after localized PCa treatment. A trigger PSA above 2.6 ng/mL seems optimal for appropriate patient selection.

Does teaching of robotic partial nephrectomy affect renal function and perioperative outcomes?

PURPOSE: Partial nephrectomy (PN) represents the treatment of choice for localized renal tumor<7cm. Minimally invasive approaches are considered standard of care in many institutions. Maintaining acceptable warm ischemic time (WIT) while teaching robotic PN (RPN) remains challenging. The goal of the present study was to assess the effect of teaching RPN on WIT and renal function in patients undergoing RPN. METHODS: Patients undergoing RPN for cT1-T2 renal tumors were included. RENAL nephrometry score was used to adjust for tumor complexity. Glomerular filtration rates (GFR) were determined preoperatively, at day 2 and at ≥3-month follow-up. Patients in whom the attending surgeon (staff) performed tumorectomy and renorraphy were compared with those in whom the fellow performed these steps. Primary outcomes were WIT and GFR decrease at follow-up visit. Morbidity and margin positivity represented secondary outcomes. RESULTS: Overall, 69 patients (46 "staff" vs. 23 "fellow") were included. Patient׳s characteristics did not differ significantly between the 2 groups. In particular, RENAL score and preoperative GFR were similar between both groups. Mean WIT was 22±9 in the staff and 24±7 in the fellow group (P = 0.09). At follow-up, a GFR reduction of 9% was observed in the staff group vs. 13% in the fellow group (P = 0.38). Complication rates (13% vs. 17%, P = 0.63) and positive margins (9% vs. 4%, P = 0.47) did not differ significantly between staff and fellow. CONCLUSIONS: In our experience, teaching RPN with a strict supervision and stepwise standardized procedure was oncologically and functionally safe after 3 to 6 months of follow-up.

New and Established Technology in Focal Ablation of the Prostate: A Systematic Review.

CONTEXT: Focal therapy of prostate cancer has been proposed as an alternative to whole-gland treatments. OBJECTIVE: To summarize the evidence regarding sources of energy employed in focal therapy. EVIDENCE ACQUISITION: Embase and Medline (PubMed) were searched from 1996 to October 31, 2015 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Ongoing trials were selected from electronic registries. The stage of assessment of each source of energy was determined using the Idea, Development, Exploration, Assessment, Long-term study recommendations. EVIDENCE SYNTHESIS: Thirty-seven articles reporting on 3230 patients undergoing focal therapy were selected. Thirteen reported on high-intensity focused ultrasound, 11 on cryotherapy, three on photodynamic therapy, four on laser interstitial thermotherapy, two on brachytherapy, three on irreversible electroporation, and one on radiofrequency. High-intensity focused ultrasound, cryotherapy, photodynamic therapy, and brachytherapy have been assessed in up to Stage 2b studies. Laser interstitial thermotherapy and irreversible electroporation have been evaluated in up to Stage 2a studies. Radiofrequency has been evaluated in one Stage 1 study. Median follow-up varied between 4 mo and 61 mo, and the median rate of serious adverse events ranged between 0% and 10.6%. Pad-free leak-free continence and potency were obtained in 83.3-100% and 81.5-100%, respectively. In series with intention to treat, the median rate of significant and insignificant disease at control biopsy varied between 0% and 13.4% and 5.1% and 45.9%, respectively. The main limitations were the length of follow-up, the absence of a comparator arm, and study heterogeneity. CONCLUSIONS: Focal therapy has been evaluated using seven sources of energy in single-arm retrospective and prospective development studies up to Stage 2b. Focal therapy seems to have a minor impact on quality of life and genito-urinary function. Oncological effectiveness is yet to be defined against standard of care. PATIENT SUMMARY: Seven sources of energy have been employed to selectively ablate discrete areas of prostate cancer. There is high evidence that focal therapy is safe and has low detrimental impact on continence and potency. The oncological outcome has yet to be evaluated against standard of care.

Intravesical Bacillus Calmette Guerin Combined with a Cancer Vaccine Increases Local T-Cell Responses in Non-muscle-Invasive Bladder Cancer Patients.

PURPOSE: Treatments with cancer vaccines may be delivered as combination therapies for better efficacy. Addition of intravesical immunostimulation with bacteria promotes vaccine-specific T cells in the bladder and tumor-regression in murine bladder cancer models. Here, we determined whether an adjuvanted cancer vaccine can be safely administered with concomitant standard intravesical Bacillus-Calmette-Guérin (BCG) therapy and how vaccine-specific immune responses may be modulated in patients with non-muscle-invasive bladder cancer (NMIBC). EXPERIMENTAL DESIGN: In a nonrandomized phase I open-label exploratory study, 24 NMIBC patients, apportioned in three groups, received 5 injections of a subunit cancer vaccine (recMAGE-A3 protein+AS15) alone or in two combinations of intravesical BCG-instillations. Safety profiles were compared between the three treatment groups, considering single vaccine injections or BCG instillations and concomitant interventions. Immune responses in blood and urine were compared between treatment groups and upon BCG instillations. RESULTS: The mild adverse events (AE) experienced by all the patients were similar to AE previously reported for this vaccine and standard BCG treatment. AEs were not increased by the double interventions, suggesting that BCG did not exacerbate the AE caused by the MAGE-A3 vaccine and vice-versa. All patients seroconverted after MAGE-A3 vaccination. In half of the patients, vaccine-specific T cells were induced in blood, irrespective of BCG treatment. Interestingly, such T cells were only detected in urine upon BCG-induced T-cell infiltration. CONCLUSIONS: Cancer vaccines, including strong adjuvants, can be safely combined with intravesical BCG therapy. The increase of vaccine-specific T cells in the bladder upon BCG provides proof-of-principle evidence that cancer vaccines with local immunostimulation may be beneficial.

The role of renal biopsy in small renal masses.

Renal biopsy is being increasingly proposed as a diagnostic tool to characterize small renal masses (SRM). Indeed, the wide adoption of imaging in the diagnostic workup of many diseases had led to a substantial increased incidence of SRM (diameter ≤4 cm). While modern ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) techniques have high sensitivity for detecting SRM, none is able to accurately and reliably characterize them in terms of histological features. This is currently of key importance in guiding clinical decision-making in some situations, and in these cases renal biopsy should be considered. In this review, we aim to summarize the technique, diagnostic performance, and predicting factors of nondiagnostic biopsy, as well as the future perspectives.

Cost-effectiveness of multiparametric magnetic resonance imaging and targeted biopsy in diagnosing prostate cancer.

INTRODUCTION: Transrectal ultrasound-guided biopsy (TRUSGB) is the recommended approach to diagnose prostate cancer (PCa). Overdiagnosis and sampling errors represent major limitations. Magnetic resonance imaging (MRI)-targeted biopsy (MRTB) detects higher proportion of significant PCa and reduces diagnosis of insignificant PCa. Costs prevent MRTB from becoming the new standard in PCa diagnosis. The present study aimed at assessing whether added costs of MRI outweigh benefits of MRTB in a cost-utility model. MATERIALS AND METHODS: A Markov model was developed to estimate quality-adjusted life-year gained (QALY) and costs for 2 strategies (the standard 12-core TRUSGB strategy and the MRTB strategy) over 5, 10, 15, and 20 years. MRI was used as triage test in biopsy-naive men with clinical suspicion of PCa. The model takes into account probability of men harboring PCa, diagnostic accuracy of both procedures, and probability of being assigned to various treatment options. Direct medical costs based on health care system perspective were included. RESULTS: Following standard TRUSGB pathway, calculated cumulative effects at 5, 10, 15, and 20 years were 4.25, 7.17, 9.03, and 10.09 QALY, respectively. Cumulative effects in MRTB pathway were 4.29, 7.26, 9.17, and 10.26 QALY, correspondingly. Costs related to TRUSGB strategy were $8,027, $11,406, $14,883, and $17,587 at 5, 10, 15, and 20 years, respectively, as compared with $7,231, $10,450, $13,267, and $15,400 for the MRTB strategy. At 5, 10, 15, and 20 years, MRTB was the established dominant strategy. CONCLUSIONS: Incorporation of MRI and MRTB in PCa diagnosis and management represents a cost-effective measure at 5, 10, 15, and 20 years after initial diagnosis.

Accuracy of cognitive MRI-targeted biopsy in hitting prostate cancer-positive regions of interest.

PURPOSE: Prostate cancer (PCa) diagnosis relies on clinical suspicion leading to systematic transrectal ultrasound-guided biopsy (TRUSGB). Multiparametric magnetic resonance imaging (mpMRI) allows for targeted biopsy of suspicious areas of the prostate instead of random 12-core biopsy. This method has been shown to be more accurate in detecting significant PCa. However, the precise spatial accuracy of cognitive targeting is unknown. METHODS: Consecutive patients undergoing mpMRI-targeted TRUSGB with cognitive registration (MRTB-COG) followed by robot-assisted radical prostatectomy were included in the present analysis. The regions of interest (ROIs) involved by the index lesion reported on mpMRI were subsequently targeted by two experienced urologists using the cognitive approach. The 27 ROIs were used as spatial reference. Mapping on radical prostatectomy specimen was used as reference to determine true-positive mpMRI findings. Per core correlation analysis was performed. RESULTS: Forty patients were included. Overall, 40 index lesions involving 137 ROIs (mean ROIs per index lesion 3.43) were identified on MRI. After correlating these findings with final pathology, 117 ROIs (85 %) were considered as true-positive lesions. A total of 102 biopsy cores directed toward such true-positive ROIs were available for final analysis. Cognitive targeted biopsy hit the target in 82 % of the cases (84/102). The only identified risk factor for missing the target was an anterior situated ROI (p = 0.01). CONCLUSION: In experienced hands, cognitive MRTB-COG allows for an accuracy of 82 % in hitting the correct target, given that it is a true-positive lesion. Anterior tumors are less likely to be successfully targeted.

[Assessment and treatment of genitourinary infections]. / Bilan et traitements des infections urogénitales.

Antibiotics are most commonly prescribed for urinary bacterial infections. The purpose of this article is to review the most common infections of the genitourinary tract and to guide the choice of the most appropriate treatment. This choice depends also on the patients general state, local associated conditions and can range from observation to an emergency hospitalisation. Primary care physicians remain in the first line to take care of these patients but the urologists or the infectious disease specialists can provide some help in complex situations.

Les infections urinaires bactériennes sont l'une des principales indications à la prescription d'antibiotiques. Le but de cet article est d'aider le praticien à reconnaître les diverses infections du tractus urogénital et à les traiter en utilisant les antibiotiques de façon appropriée. Le choix du traitement dépend aussi de l'état général du patient, de conditions locales associées et peut aller de l'abstention thérapeutique à l'hospitalisation en urgence. Le médecin de famille est en première ligne dans la prise en charge de ces pathologies fréquentes et l'urologue ou l'infectiologue peuvent apporter leur contribution dans les situations complexes.

Preoperative nutritional screening by the specialist instead of the nutritional risk score might prevent excess nutrition: a multivariate analysis of nutritional risk factors.

BACKGROUND: The aim of the current study was to assess whether widely used nutritional parameters are correlated with the nutritional risk score (NRS-2002) to identify postoperative morbidity and to evaluate the role of nutritionists in nutritional assessment. METHODS: A randomized trial on preoperative nutritional interventions (NCT00512213) provided the study cohort of 152 patients at nutritional risk (NRS-2002 ≥3) with a comprehensive phenotyping including diverse nutritional parameters (n=17), elaborated by nutritional specialists, and potential demographic and surgical (n=5) confounders. Risk factors for overall, severe (Dindo-Clavien 3-5) and infectious complications were identified by univariate analysis; parameters with P<0.20 were then entered in a multiple logistic regression model. RESULTS: Final analysis included 140 patients with complete datasets. Of these, 61 patients (43.6%) were overweight, and 72 patients (51.4%) experienced at least one complication of any degree of severity. Univariate analysis identified a correlation between few (≤3) active co-morbidities (OR=4.94; 95% CI: 1.47-16.56, p=0.01) and overall complications. Patients screened as being malnourished by nutritional specialists presented less overall complications compared to the not malnourished (OR=0.47; 95% CI: 0.22-0.97, p=0.043). Severe postoperative complications occurred more often in patients with low lean body mass (OR=1.06; 95% CI: 1-1.12, p=0.028). Few (≤3) active co-morbidities (OR=8.8; 95% CI: 1.12-68.99, p=0.008) were related with postoperative infections. Patients screened as being malnourished by nutritional specialists presented less infectious complications (OR=0.28; 95% CI: 0.1-0.78), p=0.014) as compared to the not malnourished. Multivariate analysis identified few co-morbidities (OR=6.33; 95% CI: 1.75-22.84, p=0.005), low weight loss (OR=1.08; 95% CI: 1.02-1.14, p=0.006) and low hemoglobin concentration (OR=2.84; 95% CI: 1.22-6.59, p=0.021) as independent risk factors for overall postoperative complications. Compliance with nutritional supplements (OR=0.37; 95% CI: 0.14-0.97, p=0.041) and supplementation of malnourished patients as assessed by nutritional specialists (OR=0.24; 95% CI: 0.08-0.69, p=0.009) were independently associated with decreased infectious complications. CONCLUSIONS: Nutritional support based upon NRS-2002 screening might result in overnutrition, with potentially deleterious clinical consequences. We emphasize the importance of detailed assessment of the nutritional status by a dedicated specialist before deciding on early nutritional intervention for patients with an initial NRS-2002 score of ≥3.

[Gender disparities in urologic cancers]. / Inégalité des sexes face au cancer en urologie.

The purpose of the present review is to summarize the current knowledge on the impact of gender on urological cancers. There is a discrepancy in the incidence of urothelial and kidney cancers, with a higher prediction for male patients. Men have a three-times greater risk of developing bladder cancer compared to women, but female gender has been identified as an independent adverse prognostic factor for both disease recurrence and progression. At diagnosis, men with renal cell carcinoma present more often with larger tumors and higher stage and grade disease compared to females. Smoking habits, tumor biology, sex steroid hormones, genetic differences and social behavior may be the main drivers of gender disparities. Therefore, the inclusion of this variable in validated prognostic tables and nomograms should be concretely discussed.

[Prostate biopsy: which strategy for which patient?]. / Biopsies de la prostate en 2015: quelle biopsie pour quel patient?

The adoption of multiparametric MRI within the diagnostic pathway has allowed urologists to move from random biopsy to targeted biopsy directed towards MR-visible lesions. The use of software for MR to TRUS fusion may enhance the diagnostic accuracy of targeted biopsy. To determine the eligibility for tissue-preserving approaches, further precision is required, and template prostate mapping biopsy may be offered. The employment of novel biopsy techniques provide better characterisation of the disease, and allows a tailored approach to a single subject.
