RESUMEN
PURPOSE: To compare outcomes of robotic-assisted partial nephrectomy (RAPN) and minimally invasive radical nephrectomy (MIS-RN) for complex renal masses (CRM). METHODS: We conducted a retrospective multicenter analysis of CRM patients who underwent MIS-RN and RAPN. CRM was defined as RENAL score 10-12. Primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival (CSS), recurrence, and complications. Multivariable analysis (MVA) and Kaplan-Meier Analysis (KMA) were used to analyze functional and survival outcomes for RN vs. PN by pathological stage. RESULTS: 926 patients were analyzed (MIS-RN = 437/RAPN = 489; median follow-up 24.0 months). MVA demonstrated lack of transfusion (HR = 1.63, p = 0.005), low-grade (HR = 1.18, p = 0.018) and smaller tumor size (HR = 1.05, p < 0.001) were associated with OS. Younger age (HR = 1.01, p = 0.017), high-grade (HR = 1.18, p = 0.017), smaller tumor size (HR = 1.05, p < 0.001), and lack of transfusion (HR = 1.39, p = 0.038) were associated with CSS. Increasing tumor size (HR = 1.18, p < 0.001), high-grade (HR = 3.21, p < 0.001), and increasing age (HR = 1.02, p = 0.009) were independent risk factors for recurrence. Type of surgery was not associated with major complications (p = 0.094). For KMA of MIS-RN vs. RAPN for pT1, pT2 and pT3, 5-year OS was 85% vs. 88% (p = 0.078); 82% vs. 80% (p = 0.442) and 84% vs. 83% (p = 0.863), respectively. 5-year CSS was 98% for both procedures (p = 0.473); 94% vs. 92% (p = 0.735) and 91% vs. 90% (p = 0.581). 5-year non-CSS was 87% vs. 93% (p = 0.107); 87% for pT2 (p = 0.485) and 92% for pT3 for both procedures (p = 0.403). CONCLUSION: RAPN in CRM is not associated with increased risk of complications or worsened oncological outcomes when compared to MIS-RN and may be preferred when clinically indicated.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms (LUTSs) in males. Curcumin exhibits anti-inflammatory and anti-tumor properties which may be effective for BPH. This multi-arm observational study evaluated the real-world efficacy of QURMIN® (Gamma-cyclodextrin-curcumin Complex-CAVACURMIN®) as single or combination therapy for BPH. METHODS: Men with moderate-severe LUTS/BPH, receiving a 6-month supplementation with QURMIN® alone or in combination with BPH-specific medication were propensity score matched with patients not taking curcumin and then divided into subgroups based on concomitant baseline treatment. Cohorts were compared in the 6-month variation of IPSS, quality of life (IPSS-QoL), Benign Prostatic Hyperplasia Impact Index (BII) and uroflowmetry parameters. Curcumin tolerability was evaluated in terms of discontinuations and adverse effects. RESULTS: The 1:1 propensity score matching resulted in a treatment-naïve (n = 152), an alpha-blocker only (AB) (n = 138) and AB + 5-alpha reductase inhibitors (5-ARIs) (n = 78) subgroup. After 6 months, drug-naïve patients taking curcumin reported significant improvement in IPSS-storage (-3.9, p < 0.001), IPSS-voiding (-2.0, p = 0.011), IPSS-total (-5.9, p < 0.001), IPSS-QoL (-3.9, p < 0.001), BII (-2.0, p < 0.001), Qmax (+3.1 mL/s, p < 0.001), Qmean (+1.9 mL/s, p = 0.005), post-void residual volume (-7.7 mL, p < 0.001), and PSA (-0.3 ng/mL, p = 0.003), compared to controls. Patients taking ABs and curcumin showed improvement in IPSS-storage (-2.7, p < 0.001), IPSS-voiding (-1.3, p = 0.033), IPSS-total (-3.5, p < 0.001), IPSS-QoL (-1.1, p = 0.004), BII (-1.7, p = 0.006), Qmax (+1.0 mL/s, p = 0.006), and PSA (-0.2 ng/mL, p = 0.01). Patients taking curcumin and AB + 5-ARI showed improvement in IPSS-storage (-1.3, p = 0.007), IPSS-total (-1.6, p = 0.034), IPSS-QoL (-1.1, p < 0.001), and BII (-2.0, p < 0.001). No adverse reactions were reported for curcumin supplementation. CONCLUSION: QURMIN® (CAVACURMIN®) led to significant improvements in symptom burden, uroflow parameters, and QoL, without significant additional side effects, thus proving to be a potential new treatment for BPH, either as a single therapy or in addition to standard treatment.

AIM: Renal leiomyoma is a rare benign mesenchymal tumor arising from the smooth muscle cells of the kidney. Renal capsule is its most common location (1). Large tumor may require surgical excision which can be challenging in case of proximity to major vessels (2). Indications of robotic partial nephrectomy (RPN) have exponentially expanded over the past few years (3). We aim to report a case of large renal leiomyoma successfully managed with RPN. METHODS: A 59-year-old female patient with BMI 51 presented with chief complaint of abdominal discomfort. The patient underwent a CT scan that revealed a massive circumscribed exophytic complex solid cystic mass of 4.5 x 7.7 x 6.2 cm, arising from the lower pole of right kidney and abutting the inferior vena cava. RENAL score was 11ah (high complexity). Past surgical history included mid-urethral sling, breast reduction, and hysterectomy with salpingectomy. Preoperative creatinine and eGFR were 0.9 (mg/dL) and 77 (mL/min), respectively. A robotic excision of this mass was successfully performed by using Da Vinci Xi platform. Main steps of the procedure are illustrated in the present video. RESULTS: Dissection and isolation of the tumor were carefully performed after identifying key anatomical structures such as the ureter, the IVC and the renal hilum. Intraoperative ultrasound was used to confirm the margins of the mass. The renal artery was clamped and then the tumor was resected/enucleated. Renal parenchyma was re-approximated with a single layer of interrupted CT-1 Vicryl 0 with sliding clip technique. Warm ischemia time was 19 min. Estimated blood loss (EBL) was 250 ml. Operative time was 165 min. No intraoperative complications occurred. No drain was placed. Patient was discharged on postoperative day 2. Post-operative hypotension was managed with fluid bolus. Postoperative creatinine and eGFR were 1,0 (mg/dL) and 69 (mL/min/1.72m2), respectively. Pathology revealed a leiomyoma of genital stromal origin with hyalinization and calcification. CONCLUSIONS: To the best of our knowledge, this is the first description of RPN for the management of a large (about 8 cm) renal leiomyoma. Robotic assisted surgery allows to expand the indications of minimally invasive conservative renal surgery whose feasibility becomes even more clinically significant in case of benign masses which can be managed without sacrificing healthy renal parenchyma.

BACKGROUND: In intermediate/high risk prostate cancer, preoperative staging exams are mandatory. The aim of these imaging studies is to evaluate eventual lymph nodes involvement and/or metastatic spread of the tumor. Nevertheless, computed tomography (CT), magnetic resonance imaging (MRI), bone scan modalities have controversial sensitivity. Introduction of PET-PSMA and its use also as preoperative exam, seems to improve diagnostic accuracy due to favorable negative predictive value. The aim of this study was to evaluate the accuracy of PET-PSMA as a preoperative staging exam and its accuracy in predicting lymph nodes involvement in intermediate/high risk prostate cancer (PCa) patients. METHODS: A retrospective analysis of 50 patients diagnosed with intermediate/high risk PCa between 2018 and 2022 has been performed. All patients underwent preoperative 68Ga-PSMA PET/CT prior to robot-assisted radical prostatectomy (RARP) + extended pelvic lymph node dissection (ePLND). The cohort was categorized into two groups: pathologically negative lymph nodes (pN0) vs. positive nodes (pN1). A descriptive and comparative analysis was conducted. Correlation analysis between continuous variables was performed using the Spearman's Rank Test. Using lymph nodes histopathological results as reference standard, the diagnostic performance of 68Ga-PSMA PET/CT was calculated. RESULTS: Overall, 50 patients were included. The mean age was 63.3 years with a median prostatic specific antigen (PSA) of 7.7 ng/dL. Forty-four percent of the patients exhibited an International Society of Urological Pathology (ISUP) score of 4 or higher, and 28% had a pT3 stage. Overall, 43 (86%) patients submitted to ePLND did not present lymph node metastases (pN0), while 8 (14%) patients were pN1. PET-PSMA showed low sensitivity in detecting lymph node metastases (25%) while a high specificity in excluding lymph-node disease (88.1%) has been observed. Finally, we noted a significant positive correlation between the total SUV

PURPOSE: The management of renal masses in the elderly population is particularly challenging, as these patients are often more frail and potentially more susceptible to surgical morbidity. This review aims to provide a comprehensive analysis of the outcomes of partial nephrectomy (PN) for treating renal masses in elderly individuals. METHODS: A systematic electronic literature search was conducted in May 2024 using the Medline (via PubMed) database by searching publications up to April 2024. The population, intervention, comparator, and outcome (PICO) model defined study eligibility. Studies were deemed eligible if assessing elderly patients (aged 70 years or older) (P) undergoing PN (I) with or without comparison between a different population (non-elderly) or a different treatment option (radical nephrectomy, ablation or active surveillance) (C) evaluating surgical, functional, and oncological outcomes (O). RESULTS: A total of 23 retrospective studies investigating the role of PN in elderly patients were finally included. PN emerged as a safe procedure also for older patients, demonstrating good outcomes. Preoperative evaluation of frailty status emerged to be paramount. Age alone was discredited as the sole reason to reject the use of PN. The main limitation is the retrospective nature of included studies and the lack of the assessment of elderly patients' frailty. CONCLUSIONS: The surgical treatment of renal masses in older patients is a challenging scenario. PN should be chosen over RN whenever possible since it can better preserve renal function. The use of minimally invasive techniques should be favored in this extremely fragile group of patients.
RESUMEN
BACKGROUND: An increasing number of novel surgical treatments (NSTs) for benign prostatic hyperplasia (BPH) have been proposed over time to achieve similar functional outcomes, but better perioperative and sexual outcomes than traditional procedures. OBJECTIVE: To assess the trends in the utilization and costs of BPH surgical procedures over the past decade, and to analyze the need for surgical retreatment after each procedure. DESIGN, SETTING, AND PARTICIPANTS: A retrospective observational population-based analysis was conducted using the PearlDiver Mariner (PearlDiver Technologies, Colorado Springs, CO, USA) database, including all-payer nationally available claims records collected from 2011 to 2022. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The number and type of BPH surgical procedures per year, costs associated with each BPH surgical treatment, incidence of BPH surgical retreatment rate, and time to BPH surgical retreatment were assessed. Negative binomial regression and Cochran-Armitage test were used for the temporal trend analysis. A multivariable logistic regression analysis evaluated the predictors of BPH surgical retreatment. RESULTS AND LIMITATIONS: In the study period, 274 808 patients received surgical treatment for BPH. The most common procedure was transurethral resection of the prostate (TURP; 71.7%). The overall utilization of BPH surgical treatment increased over the study period. Traditional surgery remained most performed for the entire period (87.8%), but a statistically significantly rising trend of NSTs was recorded. The mean reimbursements paid per procedure was 1.43 times higher (p < 0.001) for NSTs than for traditional procedures. The surgical retreatment rate was 9.4%. The mean time to surgical retreatment was 25.3 mo, with 85.5% of cases re-treated within 5 yr. At the multivariable analysis, transurethral incision of the prostate, photoselective vaporization of the prostate, prostatic urethral lift, convective water vapor energy, and prostatic artery embolization had a significantly greater likelihood of surgical retreatment than TURP. Holmium/thulium laser enucleation of the prostate (HoLEP/ThuLEP), open simple prostatectomy (SP), and laparoscopic/robot-assisted SP were associated with a lower probability of resurgery than TURP, but a similar probability between these procedures. Retrospective design and a lack of relevant clinical data were the main limitations. CONCLUSIONS: Over the past decade, there has been a progressive increase in the adoption of NSTs. The rate of surgical retreatment appears <10%, with patients undergoing SP and HoLEP/ThuLEP experiencing a statistically significantly lower probability of surgical retreatment. PATIENT SUMMARY: We investigated the trends, costs, and surgical retreatments of benign prostatic hyperplasia surgery. Transurethral resection of the prostate remains the most common procedure. Novel surgical treatments are associated with an upward trend, despite appearing more expensive overall. Retreatment is necessary in <10% of patients and generally within 5 yr.
RESUMEN
PURPOSE: Aim of the present study was to develop and validate a nomogram to accurately predict the risk of chronic kidney disease (CKD) upstaging at 3 years in patients undergoing robot-assisted partial nephrectomy (RAPN). METHODS: A multi-institutional database was queried to identify patients treated with RAPN for localized renal tumor (cT1-cT2, cN0, cM0). Significant CKD upstaging (sCKD-upstaging) was defined as development of newly onset CKD stage 3a, 3b, and 4/5. Model accuracy was calculated according to Harrell C-index. Subsequently, internal validation using bootstrapping and calibration was performed. Then nomogram was depicted to graphically calculate the 3-year sCKD-upstaging risk. Finally, regression tree analysis identified potential cut-offs in nomogram-derived probability. Based on this cut-off, four risk classes were derived with Kaplan-Meier analysis tested this classification. RESULTS: Overall, 965 patients were identified. At Kaplan-Meier analysis, 3-year sCKD-upstaging rate was 21.4%. The model included baseline (estimated glomerular filtration rate) eGFR, solitary kidney status, multiple lesions, R.E.N.A.L. nephrometry score, clamping technique, and postoperative acute kidney injury (AKI). The model accurately predicted 3-year sCKD-upstaging (C-index 84%). Based on identified nomogram cut-offs (7 vs 16 vs 26%), a statistically significant increase in sCKD-upstaging rates between low vs intermediate favorable vs intermediate unfavorable vs high-risk patients (1.3 vs 9.2 vs 22 vs 54.2%, respectively, p < 0.001) was observed. CONCLUSION: Herein we introduce a novel nomogram that can accurately predict the risk of sCKD-upstaging at 3 years. Based on this nomogram, it is possible to identify four risk categories. If externally validated, this nomogram may represent a useful tool to improve patient counseling and management.

BACKGROUND: Radical cystectomy (RC) shows an important impact on quality of life (QoL), for various clinical aspects. The aim of our study was to evaluate the short-term bowel function in patients that underwent RC. METHODS: Two hundred and six patients with MIBC underwent RC with ONB or IC urinary diversion. QoL was measured using the EORTC QLQ C30 and the Short-Form SF-36 questionnaires before surgery and at 12 months postoperatively. Baseline characteristics, including demographic profile, BMI, Charlson Comorbidity Index (CCI), modified Frailty Index (m-FI), pathological tumor stage, Clavien-Dindo grade, and neo-adjuvant chemotherapy were recorded and compared. RESULTS: The uni-variate and multivariate analysis (OR) were performed for constipation, diarrhea and m-FI of patients underwent RC for localized MIBC according to global health status score (poor/good vs. very good). Multivariate analysis showed that constipation medium/high was significant associated with global health status poor/good (OR=2.39; 95% CI: 1.22-4.71; P=0.01); Diarrhea medium/high was associated with global health status poor/good (OR=2.85; 95% CI:1.18-6.92; P=0.02), and m-FI ≥2 score (OR=2.13; 95% CI: 0.99-4.57; P=0.05). CONCLUSIONS: Diarrhea and constipation are associated with a lower QoL in cystectomized patients, both with ONB or IC urinary diversion; such association is especially significant in more fragile patients (Frailty Index ≥2).

Background and Objective: Radical nephroureterectomy (RNU) represents the gold standard treatment for non-metastatic upper tract urothelial cancer. We sought to provide a comprehensive review of reported oncologic outcomes of the RNU procedure and of factors that might impact these outcomes. Methods: A non-systematic review of the literature was conducted by performing an electronic literature search using PubMed with "radical nephroureterectomy" and "oncologic outcomes" as free text search terms. Both original articles and systematic reviews were considered. Search was limited to articles in English that were published in the last 20 years. Key Content and Findings: Open and laparoscopic RNU offer comparable oncologic outcomes. In more recent years, the discussion has de facto shifted towards the "oncological safety" of robotic RNU, which also seems to offer comparable oncologic outcomes. Several studies have looked at the impact of different treatment-, patient- and tumor-related factors. Among treatment-related factors, attention has been given to diagnostic ureteroscopy and the risk of intravesical recurrence. Surgical wait time and perioperative blood transfusion have also been studied. Perioperative chemotherapy, specifically adjuvant therapy, was shown to improve survival. Among patient-related factors, baseline chronic kidney disease, diabetes mellitus, body mass index, and systemic inflammation have gained recent attention. Some tumor related factors, such as stage, grade, location, and multifocality may negatively impact survival outcomes. Lymphovascular invasion and histologic variants are clinically significant pathological findings. Conclusions: RNU is a procedure with measured long-term oncologic outcomes. Minimally invasive techniques have gained an established role as they seem to offer comparable oncologic "safety", although special attention is needed in relation to the method of bladder cuff excision. Robotic RNU is gaining popularity, and while evidence remains limited, the current literature supports the oncologic safety of this procedure. Several factors, which can be categorized as treatment-related, patient-related, and tumor-related, might impact the oncologic outcomes of UTUC patients undergoing RNU. These factors can provide crucial information to stratify patients based on their relative risk of disease recurrence and mortality which may guide clinical decision-making.
RESUMEN
BACKGROUND: Ablative techniques emerged as effective alternative to nephron-sparing surgery for treatment of small renal masses. Radiofrequency ablation (RFA) and cryoablation (CRYO) are the two guidelines-recommended techniques. Microwave ablation (MWA) represents a newer technology, less described. The aim of the study was to compare outcomes of MWA to those of CRYO and RFA. METHODS: Retrospective investigation of patients who underwent MWA, CRYO, or RFA from seven high-volume US and European centers was performed. The first group included patients who underwent CRYO or RFA; the second MWA. We collected baseline characteristics, clinical, intraoperative, and postoperative data. Oncological data included technical success, local recurrence, and progression to metastasis. Multivariate analysis was performed to find predictors for postoperative complications. A composite outcome of "trifecta" was used to assess surgical, functional, and oncological outcomes. RESULTS: 739 patients underwent CRYO or RFA and 50 MWA. CRYO/RFA group had significantly longer operative time (P<0.001), but no difference in LOS, postprocedural Hb mean, intraprocedural complications (P=0.180), overall postprocedural complication rates (P=0.126), and in the 30-day re-admission rate (P=0.853) were detected. No predictive parameter of postprocedural complications was found. Concerning functional outcome, no differences were detected in terms of eGFR at 1 year (P=0.182), ΔeGFR at 1 year (P=0.825) and eGFR at latest follow-up (P=0.070). "Technical success" was achieved in 98.6% of the cases (MWA=100%, CRYO/RFA=98.5%; P=0.775), and there was no significant difference in terms of 2-year recurrence rate (P=0.114) and metastatic progression (P=0.203). Trifecta was achieved in 73.0% of CRYO/RFA vs. 69.6% of MWA cases (P=0.719). CONCLUSIONS: MWA is a safe and effective treatment option for small renal masses. Compared with CRYO/RFA, it seems to offer low complication rates, shorter operation time, and equivalent surgical and functional outcomes.

BACKGROUND: Incidentally diagnosed adrenal masses represent an entity that can result in either long term follow-up, surgical excision, or both. Understanding when and which adrenal masses are ultimately excised surgically is not well understood. We sought to understand the ultimate fate of these incidentalomas using a large population-based dataset. METHODS: The primary outcome of the study was determining the trend in adoption of surveillance vs. surgical excision according to socio-demographic, economic, and pathologic indices, and also provider specialty. Secondary outcomes were the assessment of perioperative complications, operative time, surgical approach, hospital stay, and provider specialty (general surgery vs. urology) among the cohort that underwent excision. RESULTS: Out of a total of N.=91,560 adrenal masses, ultimately N.=3375 (3.83%) of these underwent surgical excision. In the surgical excision cohort, the incidence of aldosteronoma, functional adenoma/Cushing's disease, and adrenocortical carcinoma was higher than in the surveillance cohort. Those patients who were older, female, and with higher Charlson Comorbidity indexes (CCI) were less likely to undergo surgical resection. Factors that predicted for an increased probability of resection included obtaining more CT/MRI scans as well as general surgeons as primary physician providers. Over the study period, the vast majority of surgeries were performed by surgeons other than urologists (12.9%) and open and laparoscopic approaches dominated, with the robotic-assisted approach accounting for a minority of the surgical cases (23.9%). The minimally invasive surgery (MIS) approach independently predicted for both lower rates of complications and shorter hospital stay. CONCLUSIONS: In the US, adrenal incidentalomas are more likely to undergo surveillance rather than surgical resection. In our study, surgery is mainly offered for functional or malignant disease and the receipt of surgery can vary by physician specialty. A MIS approach independently predicted for both lower rates of complications and shorter hospital stay.

OBJECTIVE: To create and validate 2 models called RENSAFE (RENalSAFEty) to predict postoperative acute kidney injury (AKI) and development of chronic kidney disease (CKD) stage 3b in patients undergoing partial (PN) or radical nephrectomy (RN) for kidney cancer. METHODS: Primary objective was to develop a predictive model for AKI (reduction >25% of preoperative eGFR) and de novo CKD≥3b (<45 ml/min/1.73m2), through stepwise logistic regression. Secondary outcomes include elucidation of the relationship between AKI and de novo CKD≥3a (<60 ml/min/1.73m2). Accuracy was tested with receiver operator characteristic area under the curve (AUC). RESULTS: AKI occurred in 452/1,517 patients (29.8%) and CKD≥3b in 116/903 patients (12.8%). Logistic regression demonstrated male sex (ORâ¯=â¯1.3, Pâ¯=â¯0.02), ASA score (ORâ¯=â¯1.3, P < 0.01), hypertension (ORâ¯=â¯1.6, P < 0.001), R.E.N.A.L. score (ORâ¯=â¯1.2, P < 0.001), preoperative eGFR<60 (ORâ¯=â¯1.8, Pâ¯=â¯0.009), and RN (ORâ¯=â¯10.4, P < 0.0001) as predictors for AKI. Age (OR 1.0, P < 0.001), diabetes mellitus (OR 2.5, P < 0.001), preoperative eGFR <60 (OR 3.6, P < 0.001) and RN (OR 2.2, P < 0.01) were predictors for CKD≥3b. AUC for RENSAFE AKI was 0.80 and 0.76 for CKD≥3b. AKI was predictive for CKD≥3a (ORâ¯=â¯2.2, P < 0.001), but not CKD≥3b (Pâ¯=â¯0.1). Using 21% threshold probability for AKI achieved sensitivity: 80.3%, specificity: 61.7% and negative predictive value (NPV): 88.1%. Using 8% cutoff for CKD≥3b achieved sensitivity: 75%, specificity: 65.7%, and NPV: 96%. CONCLUSION: RENSAFE models utilizing perioperative variables that can predict AKI and CKD may help guide shared decision making. Impact of postsurgical AKI was limited to less severe CKD (eGFR<60 ml/min 71.73m2). Confirmatory studies are requisite.

BACKGROUND: Utility of partial nephrectomy (PN) for complex renal mass (CRM) is controversial. We determined the impact of surgical modality on postoperative renal functional outcomes for CRM. METHODS: We retrospectively analyzed a multicenter registry (ROSULA). CRM was defined as RENAL Score 10-12. The cohort was divided into PN and radical nephrectomy (RN) for analyses. Primary outcome was development of de-novo estimated glomerular filtration rate (eGFR)<45 mL/min/1.73 m2. Secondary outcomes were de-novo eGFR<60 and ΔeGFR between diagnosis and last follow-up. Cox proportional hazards was used to elucidate predictors for de-novo eGFR<60 and <45. Linear regression was utilized to analyze ΔeGFR. Kaplan-Meier Analysis (KMA) was performed to analyze 5-year freedom from de-novo eGFR<60 and <45. RESULTS: We analyzed 969 patients (RN=429/PN=540; median follow-up 24.0 months). RN patients had lower BMI (P<0.001) and larger tumor size (P<0.001). Overall postoperative complication rate was higher for PN (P<0.001), but there was no difference in major complications (Clavien III-IV; P=0.702). MVA demonstrated age (HR=1.05, P<0.001), tumor-size (HR=1.05, P=0.046), RN (HR=2.57, P<0.001), and BMI (HR=1.04, P=0.001) to be associated with risk for de-novo eGFR<60 mL/min/1.73 m2. Age (HR=1.03, P<0.001), BMI (HR=1.06, P<0.001), baseline eGFR (HR=0.99, P=0.002), tumor size (HR=1.07, P=0.007) and RN (HR=2.39, P<0.001) were risk factors for de-novo eGFR<45 mL/min/1.73 m2. RN (B=-10.89, P<0.001) was associated with greater ΔeGFR. KMA revealed worse 5-year freedom from de-novo eGFR<60 (71% vs. 33%, P<0.001) and de-novo eGFR<45 (79% vs. 65%, P<0.001) for RN. CONCLUSIONS: PN provides functional benefit in selected patients with CRM without significant increase in major complications compared to RN, and should be considered when technically feasible.

Urachal carcinoma is a rare urological disease. The shortage of data about diagnosis and surgical treatment in literature makes it hard for clinicians to make a decision. Indeed, urachal carcinoma is an aggressive disease that requires prompt staging and treatment to ensure the best outcome for patients. We reviewed the last evidence about the management of urachal carcinoma to provide an easy-to-use guide for clinical practice. Patient summary: Urachal carcinoma is a rare malignancy. The literature on this challenging disease remains limited. Herein, we provide a practical guide for its management from diagnosis to treatment, which in most cases requires surgical intervention or chemotherapy.
RESUMEN
INTRODUCTION: The benefit of neoadjuvant systemic therapy (NAST) is not yet supported by randomized controlled trials in upper tract urothelial carcinoma (UTUC), but the evidence is increasing. This narrative systematic review was conducted to evaluate the available evidence on the role of NAST in patients undergoing radical nephroureterectomy (RNU) for UTUC. EVIDENCE ACQUISITION: We searched for all relevant articles or conference abstracts published and indexed in PubMed, Embase, and Scopus on July 19, 2021. The study was reported according to the PRISMA criteria and designed within the PICOS framework. We included studies comparing patients with non-metastatic UTUC who received neoadjuvant chemotherapy (NAC) or immunotherapy (NAI) with patients who underwent definitive surgery alone or surgery plus adjuvant systemic therapy. Prospective uncontrolled studies were also included. EVIDENCE SYNTHESIS: We identified 27 reports (NAC, N.=24 and NAI, N.=3) published between 2010 and 2021. Twenty of the 24 studies on NAC were retrospective comparative analyses, whereas the remaining four were prospective single-arm studies. One of the three NAI studies exclusively enrolled patients with UTUC. NAC was associated with improved survival and better pathological response relative to surgery alone, but there was no clear advantage when compared to surgery plus adjuvant chemotherapy. Overall, the drug-induced toxicity and risk of disease progression were acceptable but the inherent bias across study designs, inadequate reporting and heterogeneous definition of primary outcomes render it difficult to synthesize results, compare centers, and inform practice. CONCLUSIONS: The current level of evidence supporting NAST for UTUC is relatively low and the inability to predict responsiveness and thereby pinpoint the optimal candidates remains a major challenge. There is a need to compare NAST to adjuvant therapies using clearly defined primary endpoints as minimum reporting standards developed by a multidisciplinary team.

CONTEXT: Therapies based on immune checkpoint inhibitors (ICIs) are transforming the treatment landscape of urologic oncology. Nevertheless, an exhaustive overview of the toxicity spectrum of these novel therapies has yet to be provided. OBJECTIVE: To comprehensively investigate the incidence and profile of ICI therapy-related adverse events (AEs) across urologic cancers. EVIDENCE ACQUISITION: We searched for all clinical trials investigating the role of ICI therapy published between January 2010 and September 2021. Studies involving urologic cancers with reported overall incidence or tabulated data of treatment-related AEs (trAEs) or immune-related AEs (irAEs) were included. A systematic review and meta-analysis was performed after protocol registration in PROSPERO (CRD42021276435). EVIDENCE SYNTHESIS: We identified 2638 records, of which 92 studies (including 22942 participants) met the inclusion criteria. The pooled overall incidence was 81.6% (95% confidence interval [CI] 78.0-84.7) for any-grade trAEs and 29.3% (95% CI 24.9-34.1) for grade ≥3 trAEs. The pooled overall incidence was 34.3% (95% CI 28.5-40.7) for any-grade irAEs and 10.2% (95%CI 8.2-12.7) for grade ≥3 irAEs. On a multivariable analysis, cancer type, therapy combination, clinical settings (perioperative vs advanced/metastatic), and drug exposure were independently associated with the occurrence of trAEs or irAEs. The overall rate of treatment-related mortality was 0.94% (140 of 14 899 participants), with pneumonitis (9.3%), pneumonia (7.9%), and respiratory failure (7.1%) being the most common causes. Immune-related mortality occurred in 0.26% (28 of 10 723) patients, with pneumonitis (35.7%), hepatic failure (10.7%), and hepatitis (7.1%) being most common. CONCLUSIONS: Our study provides a comprehensive overview of ICI-associated AEs in urologic cancer patients. The spectrum and incidence of AEs vary across cancer types, ICI types, clinical settings, and therapy combinations. These findings provide important guidance to clinicians in counseling and management of patients with urologic cancers. PATIENT SUMMARY: A high proportion of patients experience immune checkpoint inhibitor-associated toxicity. Physician and patient education is critical for early recognition and proper management.

Background: Long-term renal function after partial nephrectomy (PN) is difficult to predict as it is influenced by several modifiable and nonmodifiable variables, often intertwined in complex relations. Objective: To identify variables influencing long-term renal function after PN and to assess their relative weight. Design setting and participants: A total of 457 patients who underwent either robotic (n = 412) or laparoscopic PN (n = 45) were identified from a multicenter international database. Outcome measurements and statistical analysis: The 1-yr estimated glomerular filtration rate (eGFR) percentage loss (1YPL), defined as the eGFR percentage change from baseline at 1 yr after surgery, was the outcome endpoint. Predictors evaluated included demographic data, tumor features, and operative and postoperative variables. Bayesian multimodel analysis of covariance was used to build all possible models and compare the fit of each model to the data via model Bayes factors. Bayesian model averaging was used to quantify the support for each predictor via the inclusion Bayes factor (BFincl). High-dimensional undirected graph estimation was used for network analysis of conditional independence between predictors. Results and limitations: Several models were found to be plausible for estimation of 1YPL. The best model, comprising postoperative eGFR percentage loss (PPL), sex, ischemia technique, and preoperative eGFR, was 207 times more likely than all the other models regarding relative predictive performance. Its components were part of the top 44 models and were the predictors with the highest BFincl. The role of cold ischemia, solitary kidney status, surgeon experience, and type of renorraphy was not assessed. Conclusions: Preoperative eGFR, sex, ischemia technique, and PPL are the best predictors of eGFR percentage loss at 1 yr after minimally invasive PN. Other predictors seem to be irrelevant, as their influence is insignificant or already nested in the effect of these four parameters. Patient summary: Kidney function at 1 year after partial removal of a kidney depends on sex, the technique used to halt blood flow to the kidney during surgery, and kidney function at baseline and in the early postoperative period.
