RESUMEN
OBJECTIVE: The routine drain placement following renal transplantation is currently under debate. Its benefit is uncertain and may cause complications, particularly infectious ones. Some renal transplant patients have low-productive drains, that might be unnecessary. The objective of this study is to bring to light factors influencing drain volume in kidney transplantation. MATERIALS AND METHODS: All kidney transplant patients in Tours between 2019 and 2020 were included. The characteristics of the two groups were analyzed: patients with low-productive redons (quantification less than 100mL/24h,) and patients with productive redons (≥ 100mL/24h). Univariate and multivariate analyses by logistic regression were performed to look for risk factors associated with productive drainage. RESULTS: One hundred and eighty-nine patients were included (67 in the low-productive group and 122 in the productive group). The results in the productive group showed a significantly higher proportion of retransplantation (P=0.015), overweight (P=0.012), low residual diuresis (P=0.041), and a significantly lower proportion of preemptive transplantation (P=0.008) and peritoneal dialysis (P=0.037). After an adjustment, the following variables remained significantly associated with greater drainage: overweight (OR=2.42, P=0.014; 95% CI [1.2-4.94]); retransplantation (OR=3.98, P=0.027; 95% CI [1.27-15.45]), and preemptive transplant (OR=0.22, P=0.013; 95% CI [0.06-0.7]). CONCLUSION: The non-implementation of a redon in renal transplantation could be considered, in a selected population of non-overweight patients, with significant residual diuresis for a first transplantation which should be preemptive. This could lead to a randomized controlled trial to determine the real benefits of a routine drain replacement in kidney transplantation. LEVEL OF EVIDENCE: IV.
RESUMEN
OBJECTIVE: characterize delayed hematuria (DH) after photoselective vaporization of the prostate (PVP) and identify its associated risk factors. METHODS: 1014 patients who underwent PVP at an expert center, from September 2005 through December 2021, were prospectively enrolled in a database registry. Risk factors of DH included age, prostate volume, ASA score, history of BPH surgery, history of prostate cancer, use of anticoagulation or 5ARIs, concomitant procedure, operative factors, and the duration of follow-up. RESULTS: The median operating time was 60 ± 11 min. The median specific applied energy was 318,500 Joules ± 101,347. After PVP, the mean catheterization duration was 1.6 days with a postoperative hospitalization time of 1.8 days. The median follow-up was 52 months (range 2-95 months). Hematuria occurred in 206 patients (20.3%), with 10% requiring an ER visit and 8.3% requiring hospital admission, transfusion or endoscopic clot removal. Almost 80% of hematuria episodes occurred within the first 3 months. The overall retreatment rate for clot retention was 3.7% after a mean time of 50 months. Hematuria-free survival was 97.2% after 1 year, and 89.3% after 4 years. Delayed hematuria occurred in 32 patients (3.1%). In the multivariate analysis, age, preoperative prostate volume, anticoagulant use, total applied energy, lasing time and operative time were identified as risk factors for delayed hematuria after PVP. CONCLUSION: Larger prostate volume, longer operative time, longer lasing time, and use of oral anticoagulation increase the odds of delayed hematuria after PVP, while older age is protective.

PURPOSE: This study was performed to assess the risk factors for artificial urinary sphincter (AUS) explantation in a large multicenter cohort. METHODS: We retrospectively reviewed the medical records for all 1,233 implantations of the AMS-800 AUS device in male nonneurological patients from 2005 to 2020 across 13 French centers. Patients with neurological conditions were excluded from the study. To identify factors associated with explantation-free survival, survival analysis was performed. Explantation was defined as the complete removal of the device, whereas revision referred to the replacement of the device or its components. RESULTS: The study included 1,107 patients, of whom 281 underwent AUS explantation. The median survival without explantation was 83 months. The leading causes of explantation were infection and erosion. Univariate analysis revealed several significant risk factors for explantation: age above 75 years (34.6% in the explanted group vs. 25.8% in the nonexplanted group, P=0.007), history of radiotherapy (43.5% vs. 31.3%, P=0.001), and anticoagulant use (15% vs. 8.6%, P<0.001). In logistic regression analysis, the only significant risk factor was previous radiotherapy (odds ratio [OR], 2.05; P<0.05). Cox proportional hazards analysis revealed 2 factors associated with earlier explantation: transcorporal cuff implantation (hazard ratio [HR], 2.67; P=0.01) and the annual caseload of the center (HR, 1.08; P=0.02). When specifically examining explantation due to erosion, radiotherapy was the sole factor significantly associated with the risk of erosion (OR, 2.47; P<0.05) as well as earlier erosion (HR, 1.90; P=0.039). CONCLUSION: In this series, conducted in a real-world setting across multiple centers with different volumes and levels of expertise, the median survival without AUS explantation was 83 months. This study confirms that radiotherapy represents the primary independent risk factor for AUS erosion in male nonneurological patients.
RESUMEN
BACKGROUND AND OBJECTIVE: A hilar location for a renal tumour is sometimes viewed as a limiting factor for safe partial nephrectomy. Our aim was to evaluate perioperative, oncological, and functional outcomes of robot-assisted partial nephrectomy (RAPN) for hilar tumours (RAPN-H) in comparison to RAPN for nonhilar tumours (RAPN-NH). METHODS: We conducted an observational, multicentre cohort study using prospectively collected data from the French Research Network on Kidney Cancer (UroCCR). The registry includes data for 3551 patients who underwent RAPN for localised or locally advanced renal masses between 2010 and 2023 in 29 hospitals in France. We studied the impact of a hilar location on surgery, postoperative renal function, tumour characteristics, and survival. We also compared rates of trifecta achievement (warm ischaemia time [WIT] <25 min, negative surgical margins, and no perioperative complications) between the groups. Finally, we performed a subgroup analysis of RAPN without vascular clamping. Variables were compared in univariable analysis and using multivariable linear, logistic, and Cox proportional-hazards models adjusted for relevant patient and tumour covariates. KEY FINDINGS AND LIMITATIONS: The analytical population included 3451 patients, of whom 2773 underwent RAPN-NH and 678 underwent RAPN-H. Longer WIT (ß = 2.4 min; p < 0.01), longer operative time (ß = 11.4 min; p < 0.01) and a higher risk of postoperative complications (odds ratio 1.33; p = 0.05) were observed in the hilar group. Blood loss, the perioperative transfusion rate, postoperative changes in the estimated glomerular filtration rate, and trifecta achievement rates were comparable between the groups (p > 0.05). At mean follow-up of 31.9 mo, there was no significant difference in recurrence-free survival (hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.58-1.2; p = 0.3), cancer-specific survival (HR 1.1, 95% CI 0.48-2.6; p = 0.79), or overall survival (HR 0.89, 95% CI 0.52-1.53; p = 0.69). CONCLUSIONS AND CLINICAL IMPLICATIONS: Patient and tumour characteristics rather than just hilar location should be the main determinants of the optimal surgical strategy for hilar tumours. PATIENT SUMMARY: We found that kidney tumours located close to major kidney blood vessels led to a longer operation and a higher risk of complications during robot-assisted surgery to remove the tumour. However, tumours in these locations were not related to a higher risk of kidney function loss, cancer recurrence, or death.
RESUMEN
PURPOSE: Current guidelines recommend screening and treatment of asymptomatic bacteriuria prior to all urological surgeries breaching the mucosa. But little evidence supports this recommendation. At the least, risk stratification for postoperative UTI to support this strategy is lacking. The aim of this study was to define the associated factors for postoperative febrile infectious complications (UTI or surgical site infection) in urological surgery. MATERIALS AND METHODS: We conducted a retrospective, multicentric study including all consecutive patients undergoing any urological surgery with preoperative urine culture. The primary outcome was the occurrence of a UTI or surgical site infection occurring within 30 days after surgery. RESULTS: From 2016 to 2023, in 10 centers, 2389 patients were included with 838 (35%) positive urine cultures (mono-/bi-/polymicrobial). Postoperative infections occurred in 106 cases (4.4%), of which 44 had negative urine cultures (41%), 42 had positive mono-/bimicrobial urine cultures (40%), and 20 had polymicrobial urine cultures (19%). In multivariable analysis, UTI during the previous 12 months of surgery (odds ratio [OR] 3.43; 95% CI 2.07-5.66; P < .001), monomicrobial/bimicrobial preoperative urine culture (OR 3.68; 95% CI 1.57-8.42; P = .002), polymicrobial preoperative urine culture (OR 2.85; 95% CI 1.52-5.14; P < .001), and operative time (OR 1.09; 95% CI 1.04-1.15; P < .001) were independent associated factors for postoperative febrile infections. CONCLUSIONS: Positive urine culture, including preoperative polymicrobial urine culture, prior to urological surgery was associated with postoperative infection. Additionally, patients experiencing infectious complications also had a higher incidence of other complications. The effectiveness of systematic preventive antibiotic therapy for a positive urine culture has not been conclusively established.

BACKGROUND AND OBJECTIVE: Urological infections significantly impact the wellbeing and quality of life of individuals owing to their widespread occurrence and diverse clinical manifestations. The objective of the guidelines panel was to provide evidence-based guidance on the diagnosis, treatment, and prevention of urinary tract infections (UTIs) and male accessory-gland infections, while addressing crucial public health aspects related to infection control and antimicrobial stewardship. METHODS: For the 2024 guidelines on urological infections, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences. KEY FINDINGS AND LIMITATIONS: Key recommendations emphasise the importance of a thorough medical history and physical examination for patients with urological infections. The guidelines stress the role of antimicrobial stewardship to combat the rising threat of antimicrobial resistance, providing recommendations for antibiotic selection, dosing, and duration on the basis of the latest evidence. CONCLUSIONS AND CLINICAL IMPLICATIONS: This overview of the 2024 EAU guidelines offers valuable insights into managing urological infections and are designed for effective integration into clinical practice. PATIENT SUMMARY: The European Association of Urology has issued an updated guideline on urological infections. The guidelines provide recommendations for diagnosis, treatment, and prevention, with a particular focus on minimising antibiotic use because of the increasing global threat of antimicrobial resistance.

PURPOSE: To provide a descriptive report of mortality and morbidity in the first 30 days of diagnosis of urosepsis. Secondary aim is to identify risk factors of unfavourable outcomes. METHODS: Prospective observational multicentre cohort study conducted from September 2014 to November 2018 in European hospitals. Adult patients (≥ 18 years) diagnosed with acute urosepsis according to Sepsis-2 criteria with confirmed microbiological infection were included. Outcomes were classified in one of four health states: death, multiple organ failure, single organ failure, and recovery at day 30 from onset of urosepsis. Descriptive statistics and ordinal logistic regression analysis was performed. RESULTS: Three hundred and fifty four patients were recruited, and 30-day mortality rate was 2.8%, rising to 4.6% for severe sepsis. All patients who died had a SOFA score of ≥ 2 at diagnosis. Upon initial diagnosis, 79% (n = 281) of patients presented with OF. Within 30 days, an additional 5% developed OF, resulting in a total of 84% affected. Charlson score (OR 1.14 CI 1.01-1.28), patients with respiratory failure at baseline (OR 2.35, CI 1.32-4.21), ICU admission within the past 12 months (OR 2.05, CI 1.00-4.19), obstruction causative of urosepsis (OR 1.76, CI 1.02-3.05), urosepsis with multi-drug-resistant(MDR) pathogens (OR 2.01, CI 1.15-3.53), and SOFA baseline score ≥ 2 (OR 2.74, CI 1.49-5.07) are significantly associated with day 30 outcomes (OF and death). CONCLUSIONS: Impact of comorbidities and MDR pathogens on outcomes highlights the existence of a distinct group of patients who are prone to mortality and morbidity. These findings underscore the need for the development of pragmatic classifications to better assess the severity of UTIs and guide management strategies. STUDY REGISTRATION: Clinicaltrials.gov registration number NCT02380170.

INTRODUCTION: There is limited evidence on the outcomes of robotic partial nephrectomy (RPN) and open partial nephrectomy (OPN) in obese patients (BMI ≥ 30 kg/m2). In this study, we aimed to compare perioperative and oncological outcomes of RPN and OPN. METHODS: We relied on data from patients who underwent PN from 2009 to 2017 at 16 departments of urology participating in the UroCCR network, which were collected prospectively. In an effort to adjust for potential confounders, a propensity-score matching was performed. Perioperative outcomes were compared between OPN and RPN patients. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS: Overall, 1277 obese patients (932 robotic and 345 open were included. After propensity score matching, 166 OPN and 166 RPN individuals were considered for the study purposes; no statistically significant difference among baseline demographic or tumor-specific characteristics was present. A higher overall complication rate and major complications rate were recorded in the OPN group (37 vs. 25%, p = 0.01 and 21 vs. 10%, p = 0.007; respectively). The length of stay was also significantly longer in the OPN group, before and after propensity-score matching (p < 0.001). There were no significant differences in Warm ischemia time (p = 0.66), absolute change in eGFR (p = 0.45) and positive surgical margins (p = 0.12). At a median postoperative follow-up period of 24 (8-40) months, DFS and OS were similar in the two groups (all p > 0.05). CONCLUSIONS: In this study, RPN was associated with better perioperative outcomes (improvement of major complications rate and LOS) than OPN. The oncological outcomes were found to be similar between the two approaches.

Background: There is no definitive evidence of the prognosis impact of histological variants (HVs) in patients who undergo surgical resection of a nonmetastatic renal cell carcinoma (nm-RCC) with venous tumor thrombus (TT). Objective: To investigate the impact of HVs on the prognosis of patients with nm-RCC with TT after radical surgery. Design setting and participants: Patients who underwent radical nephrectomy with the removal of the venous TT for an nm-RCC were included in a retrospective study. Outcome measurements and statistical analysis: Three groups were identified: clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) RCC. The primary outcome measures (disease-free and overall survival [OS]) were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate Cox proportional hazard models were used to study the impact of HVs on survival. Results and limitations: A total of 873 patients were included. The histological subtypes were distributed as follows: ccRCC in 780 cases, pRCC in 58 cases, and chRCC in 35 cases. At the time of data analysis, 612 patients were recurrence free and 228 had died. A survival analysis revealed significant differences in both OS and recurrence-free survival across histological subtypes, with the poorest outcomes observed in pRCC patients (p < 0.05). In a multivariable analysis, pRCC was independently associated with worse disease-free survival and OS (hazard ratio [HR]: 1.71; p = 0.01 and HR: 1.24; p = 0.04), while chRCC was associated with more favorable outcomes than ccRCC (HR: 0.05; p < 0.001 and HR: 0.02; p < 0.001). A limitation of the study is its retrospective nature. Conclusions: In this multicentric series, HVs appeared to impact the medium-term oncological prognosis of kidney cancer with TT. Patient summary: This study investigated the differences in oncological outcomes among histological variants (clear cell, papillary, and chromophobe) in a cohort of nonmetastatic renal cell carcinoma patients with venous tumor thrombus extension. We observed that these histological variants within this specific subgroup exhibit distinct outcomes, with papillary renal cell carcinoma being associated with the worst prognosis.
RESUMEN
INTRODUCTION: In the era of increased bacterial resistance, the main strategy is to reduce the prescription of antibiotics when possible. Nowadays, it is highly recommended to screen for asymptomatic bacteriuria (ABU), prior to urological surgery with potential mucosal breach or urine exposure. Screening and treating urinary colonization is a strategy widely adopted before radical and partial nephrectomy but without any evidence. Our main end point in this study is to analyze the relationship between preoperative urine culture and the risk of postoperative febrile urinary tract infection (UTI) or surgical-site infection (SSI) in partial or radical nephrectomy patients. METHODS: We conducted a multicenter retrospective cohort study between January 2016 and January 2023 in 11 French tertiary referral hospitals (TOCUS database). We collected the data for 269 patients including several pre-, intra-, and post-operative variables that could potentially increase the risk of postoperative UTI and SSI including preoperative urinary culture results. RESULTS: The incidence rate of postoperative UTI and SSI was 8.9% in our study. After conducting a logistic multivariate analysis, a propensity score matching analysis, and a subgroup analysis, we found no significant correlation between the urine culture and the postoperative UTI risk [OR = 1.2 (0.5-2.7) (p = 0.7)]. Only the postoperative non-infectious complications were related to a higher risk of postoperative UTI [OR = 12 (4-37), p < 0.001)]. CONCLUSION: Our research shows that screening and treating for ABU prior to radical or partial nephrectomy seems to be unnecessary to prevent postoperative UTI and SSI.

RESUMEN
INTRODUCTION: Artificial urinary sphincter (AUS) is the standard treatment for severe stress urinary incontinence in men. While the perineal access is considered the gold standard, some authors have proposed penoscrotal AUS in order to facilitate the procedure. The main objective of our study was to evaluate the duration of survival without revision surgery (SSRC) according to the surgical approach for primary implantation. MATERIAL AND METHODS: Data from 1179 patients implanted in France between 1991 and 2020 with an AMS 800 AUS were retrospectively analyzed. A total of 762 men were implanted perineally (VP) and 417 penoscrotally (VPS). RESULTS: Median follow-up was 20 vs. 25months respectively. The groups were equivalent overall, apart from the use of anticoagulants (11% VP vs. 6.3% VPS P=0.014). In our population, 54% patients were considered as "dry" in the case of VPS vs. 42% for VP. There was no significant difference in terms of survival time without reoperation, revision, replacement or explantation. In univariate and multivariate analysis, age over 70years was predictive of more reinterventions, whereas the use of a 4.5cm cuff was protective, with hazard ratios of 1.42 (P=0.001) and 0.78 (P=0.04), respectively. CONCLUSION: The penoscrotal approach does not appear to be associated with more complications, has good functional results and no significant difference in reoperation-free survival. A prospective multicenter non-inferiority study could be of interest to confirm our findings.
RESUMEN
Although tuberculosis (TB) ranks among the most frequent infectious diseases worldwide, one of its extrapulmonary (EP) manifestations, genitourinary (GU) TB, is often underestimated by urologists, particularly in areas such as Europe where TB is not endemic. The aim of this review is to give urologists a concise overview of GUTB as a supplement to the more comprehensive European Association of Urology 2023 update on urological infections guidelines. EPTB can develop in 16% of TB cases. GUTB accounts for 4.6% of EPTB and is often asymptomatic or nonspecific, so it can be confused with other urogenital diseases. GUTB can be highly destructive, leading to failure of urogenital organs. Diagnosis is via microbiological, molecular, and histological testing for urine, genital secretions, or genitourinary tissue, supported by imaging. A 6-mo combinational medical regimen is the first-line treatment for GUTB. However, surgical interventions are also frequently required for the treatment of GUTB complications. Therefore, it is important to keep GUTB in mind for differential diagnosis. PATIENT SUMMARY: We reviewed scientific studies on the occurrence, diagnosis, and treatment of tuberculosis in the genitourinary tract. Our aim is to raise awareness among urologists from countries where this disease does not occur frequently, as urogenital tuberculosis can occur without any symptoms or with unspecific symptoms that can be confused with other diseases.

PURPOSE: Persistence or recurrence of stress urinary incontinence (prSUI) after artificial urinary sphincter (AUS) implantation may be secondary to non-mechanical failure (NOMECA). It have for long been assumed to result from urethral atrophy. Its existence is now debated. As the pathophysiology of NOMECA is not elucidated, the most appropriate management remains unclear. We aimed to compare the several revision techniques for NOMECA of AUS in men. METHODS: NOMECA was defined as prSUI, with normally functioning device, no erosion, infection or fluid loss. Exclusion criteria were neurogenic SUI, revision or explantation for other causes. From 1991 to 2022, 143 AUS revisions for NOMECA, including 99 cuff DOWNSIZING, 10 cuff repositioning (RELOC), 13 TANDEM-CUFF placement, 18 cuff changing (CHANGE), three increasing balloon pressure (BALLOON-UP), were performed in 10 centers. BALLOON-UP patients weren't included in comparative analysis due to small sample size. All components could be changed during the revision. Patients were also categorized in COMPLETE-CHANGE vs. PARTIAL-CHANGE of the device. RESULTS: The three-months complete continence rate was 70.8% with a significant difference between RELOC and DOWNSIZING groups (p = 0.04). COMPLETE CHANGE was significantly associated with complete continence status at three months in multivariate analysis (83.3% vs. 63.3%, OR = 2.7; CI 95% [1.1-7.1], p = 0.03). Estimated five-year reoperation-free and explantation-free survival were respectively 63.4% and 75.9% (p = 0.16; p = 0.30). Those were significantly longer in COMPLETE-CHANGE vs PARTIAL-CHANGE (82.2% vs. 69.6%, p = 0.03); (71.2% vs. 58.2%, p = 0.047). CONCLUSIONS: AUS revision for prSUI due to NOMECA yields satisfactory outcomes regardless of the technique used. We observed better functional outcomes when repositioning the new cuff. COMPLETE-CHANGE may improve functional outcomes, explantation-free and reoperation-free survivals.

Acute pyelonephritis (AP) epidemiology has been sparsely described. This study aimed to describe the evolution of AP patients hospitalised in France and identify the factors associated with urinary diversion and fatality, in a cross-sectional study over the 2014-2019 period. Adult patients hospitalised for AP were selected by algorithms of ICD-10 codes (PPV 90.1%) and urinary diversion procedure codes (PPV 100%). 527,671 AP patients were included (76.5% female: mean age 66.1, 48.0% Escherichia coli), with 5.9% of hospital deaths. In 2019, the AP incidence was 19.2/10,000, slightly increasing over the period (17.3/10,000 in 2014). 69,313 urinary diversions (13.1%) were performed (fatality rate 6.7%), mainly in males, increasing over the period (11.7% to 14.9%). Urolithiasis (OR [95% CI] =33.1 [32.3-34.0]), sepsis (1.73 [1.69-1.77]) and a Charlson index ≥3 (1.32 [1.29-1.35]) were significantly associated with urinary diversion, whereas E. coli (0.75 [0.74-0.77]) was less likely associated. The same factors were significantly associated with fatality, plus old age and cancer (2.38 [2.32-2.45]). This nationwide study showed an increase in urolithiasis and identified, for the first time, factors associated with urinary diversion in AP along with death risk factors, which may aid urologists in clinical decision-making.

BACKGROUND: The SPARE Nephrometry Score (NS) is described as easier to implement than the RENAL and PADUA NSs, currently more widely used. Our objective was to compare the accuracy of SPARE NS in predicting renal function outcomes following RAPN. METHODS: A multicentric retrospective study was conducted using French kidney cancer network (UroCCR, NCT03293563) database. All patients included had RAPN for cT1 renal tumors between May 2010 and March 2021. SPARE was compared to RENAL, PADUA and Tumor Size to predict postoperative acute kidney injury (AKI), chronic kidney disease (CKD) upstaging, de novo CKD at 3-6 months follow-up and Trifecta failure. The ability of the different NSs and tumor size to predict renal function outcomes was evaluated using uni- and multivariate logistic regression models. RESULTS: According to our study criteria, 1171 patients were included. Mean preoperative tumor size and estimated glomerular filtration rate (eGFR) were 3.4±1.4 cm and 85.8 mL/min/1.73 m2. In total, 266 (22.7%), 87 (7.4%), 94 (8%), and 624 (53.3%) patients had AKI, de novo CKD, CKD upstaging, and Trifecta failure, respectively. In multivariate analysis, all three NSs and tumor size were independent predictors of AKI, CKD de novo, CKD upgrade and Trifecta failure. There was no significant difference between all three NS and tumor sizes in predicting renal function outcomes. CONCLUSIONS: SPARE Score seems to be a valid alternative to predict renal function outcomes after RAPN. Nevertheless, in our study, tumor size was as accurate as NSs in predicting postoperative outcomes and, therefore, seems to be the logical choice for surgical decisions.

PURPOSE: Ejaculatory dysfunction is the most common side effect of benign prostatic hyperplasia surgery. Modified techniques have emerged with the aim of preserving antegrade ejaculation without compromising obstruction relief. None are standardized or validated. The PARTURP study is a randomized study investigating partial versus complete prostate resection. We conducted an investigator consensus meeting to define the ideal surgical technique to achieve both correct obstruction relief with ejaculation preservation. METHODS: An expert consensus meeting involving all investigators of the PARTURP study took place to define a common technique using the nominal group methodology. The objectives were to define the areas to be resected and the areas to be preserved; to define the criteria for proper obstruction relief; to define the criteria for proper ejaculation preservation. RESULTS: All investigators (n = 15) attended the consensus meeting, and agreement between all the participants was obtained. The anatomical landmarks to be preserved are located around the verumontanum and along the posterior part of the prostatic urethra. These structures must be preserved up to 2 cm from the verumontanum. The participants agreed on the need to preserve the urethral mucosa in all the areas to be preserved and to reach the enucleation plane in the areas of resection. CONCLUSIONS: Anatomical landmarks for ejaculation-sparing surgery have been defined by the investigators of the PARTURP randomized study. These landmarks will be used during the study, and the clinical outcomes of this ejaculation-sparing technique will be compared with complete resection with up to 3 years follow-up.

BACKGROUND: Robot-assisted partial nephrectomy can be performed through either a transperitoneal or retroperitoneal approach. This study aimed to compare the rate of trifecta achievement between retroperitoneal (RRPN) and transperitoneal (TRPN) robot-assisted partial nephrectomy using a large multicenter prospectively-maintained database and propensity-score matching analysis. METHODS: This study was launched by the French Kidney Cancer Research Network, under the UroCCR Project (NCT03293563). Patients who underwent TRPN or RRPN by experienced surgeons in 15 participating centers were included. Data on demographic and clinical parameters, tumor characteristics, renal function, and surgical parameters were collected. The primary outcome was the rate of trifecta achievement, which was defined as a warm ischemia time of less than 25 minutes, negative surgical margins, and no major complications. Secondary outcomes included operative time, hospital length-of-stay, blood loss, postoperative complications, postoperative renal function, and each trifecta item taken alone. Subgroup analysis was done according to tumor location. RESULTS: A total of 2879 patients (2581 TRPN vs. 298 RRPN) were included in the study. Before matching, trifecta was achieved in 73.0% of the patients in the TRPN group compared to 77.5% in the RRPN group (P=0.094). After matching 157 patients who underwent TRPN to 157 patients who underwent RRPN, the trifecta rate was 82.8% in the TRPN group vs. 84.0% in the RRPN group (P=0.065). The RRPN group showed shorter operative time (123 vs. 171 min; P<0.001) and less blood loss (161 vs. 293 mL; P<0.001). RRPN showed a higher trifecta achievement for posterior tumors than TRPN (71% vs. 81%; P=0.017). CONCLUSIONS: RRPN is a viable alternative to the transperitoneal approach, particularly for posterior renal tumors, and is a safe and effective option for partial nephrectomy.

RAPN can be carried out via a transperitoneal or retroperitoneal approach. The choice between the two approaches is open to debate and usually based on surgeon preference. The perioperative outcomes of transperitoneal robot-assisted partial nephrectomy versus retroperitoneal robot-assisted partial nephrectomy were compared. A systematic review of the literature was performed up to May 2020, using PubMed, Cochrane, Scopus and Ovid databases. Articles were selected according to a search strategy based on PRISMA criteria. Only studies comparing TRAPN with RRAPN were eligible for inclusion. Eleven studies were included in the quantitative synthesis. Baseline demographics (age, BMI, ASA, tumour size, and RENAL nephrometry score), intraoperative data (operative time, estimated blood loss, and warm ischaemia time) and postoperative outcomes (major complications according to Clavien-Dindo, length of hospital stay (LOS) and positive surgical margin rate) were recorded. A total of 3139 patients were included (2052 TRAPN vs. 1087 RRAPN). There was no significant difference in demographic variables (age, BMI), tumour size (p = 0.06) nor the nephrometry score (p = 0.20) between the two groups. Operative time (p = 0.02), estimated blood loss (p < 0.00001) and LOS (p < 0.00001) were significantly lower in the RRAPN group. No differences were found in major postoperative complications (Clavien-Dindo > 3; p = 0.37), warm ischaemia time (p = 0.37) or positive surgical margins (p = 0.13). Future researchers must attempt to achieve adequately powered, expertise based, multi-surgeon and multi-centric studies comparing TRAPN and RRAPN. RRAPN gives similar outcomes to TRAPN. RRAPN is associated with reduced operative time and LOS. Ideally, surgeons should be familiar and competent in both RAPN approaches and adopt a risk-stratified and patient-centred individualised approach, dependent on the tumour and patient characteristics. RAPN is feasible via two approaches. The retroperitoneal approach seems to be associated with a shorter operation time and hospital stay.

Robot-assisted partial nephrectomy (RAPN) is the standard of care for small, localized kidney tumors. This surgery is conducted within a short hospital stay and can even be performed as outpatient surgery in selected patients. In order to allow early rehabilitation of patients, an optimal control of postoperative pain is necessary. High-pressure pneumoperitoneum during surgery seems to be the source of significant pain during the first hours postoperatively. Our study is a prospective, randomized, multicenter, controlled study which aims to compare post-operative pain at 24 h between patients undergoing RAPN at low insufflation pressure (7 mmHg) and those operated on at standard pressure (12 mmHg) using the AirSeal system.This trial is registered in the US National Library of Medicine Trial Registry (NCT number: NCT05404685).
