Matching BRCA and prostate cancer in a public health system: Report of the Italian Society for Uro-Oncology (SIUrO) consensus project.

The recent approval of PARP inhibitors for the treatment of metastatic -castration-resistant prostate cancer (mCRPC) patients with BRCA mutations firstly introduced the possibility of proposing a targeted treatment in this disease. However, the availability of this therapeutic option raises a number of questions concerning the management of prostate cancer in everyday clinical practice: the timing and method of detecting BRCA mutations, the therapeutic implications of the detection, and the screening of the members of the family of a prostate cancer patient with a BRCA alteration. These challenging issues led the Italian Society for Uro-Oncology (SIUrO) to organise a Consensus Conference aimed to develop suggestions capable of supporting clinicians managing prostate cancer patients. The present paper described the development of the statements discussed during the consensus, which involved all of the most important Italian scientific societies engaged in the multi-disciplinary and multi-professional management of the disease.

Validation of a Novel Three-Dimensional (3D Fusion) Gross Sampling Protocol for Clear Cell Renal Cell Carcinoma to Overcome Intratumoral Heterogeneity: The Meet-Uro 18 Study.

We aimed to overcome intratumoral heterogeneity in clear cell renal cell carcinoma (clearRCC). One hundred cases of clearRCC were sampled. First, usual standard sampling was applied (1 block/cm of tumor); second, the whole tumor was sampled, and 0.6 mm cores were taken from each block to construct a tissue microarray; third, the residual tissue, mapped by taking pieces 0.5 × 0.5 cm, reconstructed the entire tumor mass. Precisely, six randomly derived pieces of tissues were placed in each cassette, with the number of cassettes being based on the diameter of the tumor (called multisite 3D fusion). Angiogenic and immune markers were tested. Routine 5231 tissue blocks were obtained. Multisite 3D fusion sections showed pattern A, homogeneous high vascular density (10%), pattern B, homogeneous low vascular density (8%) and pattern C, heterogeneous angiogenic signatures (82%). PD-L1 expression was seen as diffuse (7%), low (33%) and absent (60%). Tumor-infiltrating CD8 scored high in 25% (pattern hot), low in 65% (pattern weak) and zero in 10% of cases (pattern desert). Grading was upgraded in 26% of cases (G3-G4), necrosis and sarcomatoid/rhabdoid characters were observed in, respectively, 11 and 7% of cases after 3D fusion (p = 0.03). CD8 and PD-L1 immune expressions were higher in the undifferentiated G4/rhabdoid/sarcomatoid clearRCC subtypes (p = 0.03). Again, 22% of cases were set to intermediate to high risk of clinical recurrence due to new morphological findings of all aggressive G4, sarcomatoid/rhabdoid features by using 3D fusion compared to standard methods (p = 0.04). In conclusion, we propose an easy-to-apply multisite 3D fusion sampling that negates bias due to tumor heterogeneity.

Complication rate after cystectomy following pelvic radiotherapy: an international, multicenter, retrospective series of 682 cases.

PURPOSE: Conflicting evidence exists on the complication rates after cystectomy following previous radiation (pRTC) with only a few available series. We aim to assess the complication rate of pRTC for abdominal-pelvic malignancies. METHODS: Patients treated with radical cystectomy following any previous history of RT and with available information on complications for a minimum of 1 year were included. Univariable and multivariable logistic regression models were used to assess the relationship between the variable parameters and the risk of any complication. RESULTS: 682 patients underwent pRTC after a previous RT (80.5% EBRT) for prostate, bladder (BC), gynecological or other cancers in 49.1%, 27.4%, 9.8% and 12.9%, respectively. Overall, 512 (75.1%) had at least one post-surgical complication, classified as Clavien ≥ 3 in 29.6% and Clavien V in 2.9%. At least one surgical complication occurred in 350 (51.3%), including bowel leakage in 6.2% and ureteric stricture in 9.4%. A medical complication was observed in 359 (52.6%) patients, with UTI/pyelonephritis being the most common (19%), followed by renal failure (12%). The majority of patients (86%) received an incontinent urinary diversion. In multivariable analysis adjusted for age, gender and type of RT, patients treated with RT for bladder cancer had a 1.7 times increased relative risk of experiencing any complication after RC compared to those with RT for prostate cancer (p = 0.023). The type of diversion (continent vs non-continent) did not influence the risk of complications. CONCLUSION: pRTC carries a high rate of major complications that dramatically exceeds the rates reported in RT-naïve RCs.

Oncological impact of inflammatory biomarkers in elderly patients treated with radical cystectomy for urothelial bladder cancer.

OBJECTIVE: To evaluate the impact of preoperative markers of systemic inflammation on complications and oncological outcomes in patients aged ≥75 years treated with radical cystectomy (RC) for urothelial bladder cancer (UBC). PATIENTS AND METHODS: The clinical data of 694 patients treated with open RC for UBC at our institution between January 2008 and December 2015 were retrospectively reviewed. Patients aged <75 years, with distant metastases, other-than-urothelial histological type, comorbidities that could affect the systemic inflammatory markers, and patients who received neoadjuvant chemotherapy were excluded. Multivariable regression models were built for the prediction of major postoperative surgical complications, disease recurrence, cancer-specific mortality (CSM), and overall mortality (OM). RESULTS: The median (interquartile range [IQR]) age at surgery was 79 (75-83) years. Major postoperative surgical complications were registered in 41.9% of the patients. The 5-year overall survival, cancer-specific survival and recurrence-free survival rates were 42.4% (95% confidence interval [CI] 34.7-49.9%), 70.3% (95% CI 62.3-76.9%), and 59.8% (95% CI 52.4-66.5), respectively. At multivariable analysis, higher levels of fibrinogen and a modified Glasgow Prognostic Score (mGPS) of 1 and 2 at baseline were independently associated with higher risk of major postoperative complications and of CSM. The inclusion of mGPS and fibrinogen to a standard multivariable model for recurrence and for CSM increased discrimination from 69.4% to 73.0% and from 71.3% to 73.9%, respectively. Preoperative neutrophil-to-lymphocyte ratio of >3 was independently associated with OM (hazard ratio 1.38, 95% CI 1.01-1.77; P = 0.01). CONCLUSIONS: In a cohort of elderly patients with UBC treated with RC, fibrinogen and mGPS appeared to be the most relevant prognostic measurements and increased the accuracy of clinicopathological preoperative models to predict major postoperative complications, disease recurrence and mortality. ABBREVIATIONS: ASA: American Society of Anesthesiologists; CCI: Charlson Comorbidity Index; CIS: carcinoma in situ; CRP: C-reactive protein; CSM: cancer-specific mortality; CSS: cancer-specific survival; ECOG PS: Eastern Cooperative Oncology Group Performance Status; HDL: high-density lipoprotein; (S)HR: (subdistribution) hazard ratio; LND: lymphadenectomy; LVI: lymphovascular invasion; mGPS: modified Glasgow Prognostic Score; NLR: neutrophil-to-lymphocyte ratio; NOC: non-organ-confined; OM: overall mortality; OR: odds ratio; OS: overall survival; RC: radical cystectomy; RNU: radical nephroureterectomy; UBC: urothelial bladder cancer; UTUC: upper urinary tract urothelial carcinoma.

Monitoring Patients with Metastatic Hormone-Sensitive and Metastatic Castration-Resistant Prostate Cancer: A Multidisciplinary Consensus Document.

BACKGROUND: The availability of a number of agents that are efficacious in patients with metastatic prostate cancer (mPC) has led to them being used sequentially, and this has prolonged patient survival. However, in order to maximize their efficacy, clinicians need to be able to obtain a reliable picture of disease evolution by means of monitoring procedures. METHODS: As the intensive monitoring protocols used in pivotal trials cannot be adopted in everyday clinical practice and there is no agreement among the available guidelines, a multidisciplinary panel of Italian experts met to develop recommendations for monitoring mPC patients using a modified Delphi method. RESULTS: The consensus project considered methods of clinically, radiographically, and biochemically monitoring patients with metastatic hormone-sensitive and metastatic castration-resistant prostate cancer undergoing chemotherapy and/or hormonal treatment. The panelists also considered the methods and timing of monitoring castration levels, bone health, and the metabolic syndrome during androgen deprivation therapy. CONCLUSIONS: The recommendations, which were drawn up by experts following a formal and validated consensus procedure, will help clinicians face the everyday challenges of monitoring metastatic prostate cancer patients.

Management of kidney cancer patients: 2018 guidelines of the Italian Medical Oncology Association (AIOM).

In the past two decades, the treatment landscape for patients with metastatic renal cell carcinoma has significantly changed thanks to the approval of several targeted molecular therapies (VEGF and mTOR inhibitors) and recently immune-checkpoint inhibitors. The Italian Association of Medical Oncology (AIOM) Renal Cell Cancer (RCC) Guidelines Panel has developed clinical guidelines to provide evidence-based information and recommendations to oncologists, urologists and all professionals involved in the management of patients with renal cell cancer.

Techniques and outcomes of minimally-invasive surgery for nonmetastatic renal cell carcinoma with inferior vena cava thrombosis: a systematic review of the literature.

INTRODUCTION: Current guidelines recommend considering surgical excision of non-metastatic renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombosis in patients with acceptable performance status. Of note, several authors have pioneered specific techniques for laparoscopic and robotic management of renal cancer with level I-IV IVC thrombosis. EVIDENCE ACQUISITION: A systematic review of the English-language literature on surgical techniques and perioperative outcomes of minimally-invasive radical nephrectomy (RN) and IVC thrombectomy for nonmetastatic RCC was performed without time filters using the MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials and Web of Science (WoS) databases in September 2018 according to the PRISMA statement recommendations. EVIDENCE SYNTHESIS: Overall, 28 studies were selected for qualitative analysis (N.=13 on laparoscopic surgery, N.=15 on robotic surgery). The quality of evidence according to GRADE was low. Laparoscopic techniques included hand-assisted, hybrid and pure laparoscopic approaches. Most of these series included right-sided tumors with predominantly level I or II IVC thrombi. Similarly, most robotic series reported right-sided RCC with level I-II IVC thrombosis; yet, few authors extended the indication to level III thrombi and to left-sided RCC. Surgical techniques for minimally-invasive IVC thrombectomy evolved over the years, with specific technical nuances aiming to tailor surgical strategy according to both tumor side and thrombus extent. Among the included studies, perioperative outcomes were promising. CONCLUSIONS: Minimally-invasive surgery is technically feasible and has been shown to achieve acceptable perioperative outcomes in selected patients with renal cancer and IVC thrombosis. The evidence is premature to draw conclusions on intermediate-long term oncologic outcomes. Robotic surgery allowed to extend surgical indications to more challenging cases with more extensive tumor thrombosis. Nonetheless, global experience on minimally-invasive IVC thrombectomy is limited to high-volume surgeons at high-volume Centers. Future research is needed to prove its non-inferiority as compared to open surgery and to define its benefits and limits.

Oncologic outcomes in patients treated with endoscopic robot assisted simple enucleation (ERASE) for renal cell carcinoma: Results from a tertiary referral center.

INTRODUCTION: Open Simple Enucleation (OSE) has been demonstrated to be an oncologically safe alternative to standard partial nephrectomy. We assessed the mid-term oncologic outcomes and predictors of disease recurrence in patients treated with Endoscopic Robot-Assisted Simple Enucleation (ERASE) verified through a standardized reporting system at a single institution. MATERIAL AND METHODS: The clinical data of patients treated with ERASE for renal cell carcinoma at our Institution from January 2012 to September 2018 were retrospectively reviewed. Surface-Intermediate-Base (SIB) score was evaluated immediately after surgery. Patients with a ≥2 SIB score were excluded. The local and distant recurrence rates, the recurrence-free (RFS), cancer-specific (CSS) and overall (OS) survival were assessed. Kaplan-Meier and log-rank test were used to estimate survivals and to compare recurrence-free survival. RESULTS: Overall, 259 patients were considered eligible for the present study. The median PADUA score was 7 (interquartile range [IQR] 6-9). Positive surgical margins (PSM) were registered in 7 (2.7%) cases. Median (IQR) follow-up time was 36 (27-51) months. Overall, 4 (1.5%) patients experienced systemic recurrence (SR) and 5 (1.9%) patients experienced local recurrence alone (LR) of whom 3 (1.1%) were on tumor resection bed, and 2 (0.8%) experienced recurrence elsewhere in the ipsilateral kidney. The 5-year RFS, CSS and OS were 94.2%, 98.9% and 93.6%, respectively. Higher nucleolar grade and PSM were the two factors significantly associated with worse RFS. CONCLUSIONS: ERASE is a safe procedure, achieving negative surgical margins in the vast majority of patients and providing excellent mid-term local control and oncologic outcomes.

Surgical management of a rare case of giant penile cancer.

Primary penile cancer is a rare malignant disease. In most cases, it presents as a clinically obvious lesion leading to early diagnosis in most patients. However, even in developed Countries, it carries a significant social stigma leading to diagnosis at locally advanced stages in a non-negligible proportion of patients. Yet, bulky penile lesions are becoming extremely rare in current clinical practice. We present a case of a patient with a giant primary penile cancer managed with radical penectomy, bilateral inguinal lymphadenectomy and perineal urethrostomy, who experienced disease recurrence six months after surgery and died with metastatic disease after denial of further treatment. The management of our case was challenging due to the extremely late diagnosis, the huge dimensions and the infiltrative nature of the tumor; however, from a histopathological perspective, the cancer itself did not display any microscopic peculiarity. Our case highlights that such bulky penile tumors can still occur in current urologic practice and require complex salvage surgical interventions in the context of a multidisciplinary setting.

Tumor-parenchyma interface and long-term oncologic outcomes after robotic tumor enucleation for sporadic renal cell carcinoma.

OBJECTIVE: Tumor enucleation has been shown to be oncologically safe for elective treatment of renal cell carcinoma (RCC); yet, evidence on long-term oncologic outcomes after robotic tumor enucleation is lacking. In this study we provide a detailed histopathological analysis of tumor-parenchyma interface and the long-term oncologic outcomes after robotic tumor enucleation for sporadic RCC in a high-volume referral center. MATERIALS AND METHODS: We selected consecutive patients undergoing robotic tumor enucleation for sporadic RCC by experienced surgeons with at least 4 years of follow-up. Pattern of pseudocapsule (PC) invasion, thickness of healthy renal margin removed with the tumor, margin status and recurrence rate were the main study endpoints. Multivariable models evaluated independent predictors of PC invasion. RESULTS: Overall, 140 patients were eligible for the study. Of these, 127 (91%) had complete data available for analysis. Median thickness of healthy renal margin was 0.57 mm (interquartile range [IQR] 0.24-103). A distinct peritumoral PC was present in 121/127 (95%) tumors with a median thickness of 0.28 mm (IQR 0.14-0.45). In 24/121 (19.8%) cases, RCC showed complete PC invasion. At multivariable analysis, increasing tumor diameter, endophytic rate > 50% and papillary histology were significantly associated with complete PC invasion. Positive surgical margins were reported in 3/127 (2.4%) cases. At a median follow-up of 61 months (range 48-76), one patient died due to metastatic RCC. Among patients alive at follow-up, no cases of recurrence at the enucleation site were recorded, while three cases (2.4%) of renal recurrence (elsewhere in the ipsilateral kidney) and three cases (2.4%) of systemic recurrence were found. CONCLUSIONS: Distinct RCC-related features were associated with complete PC invasion. By providing a microscopic layer of healthy renal margin in almost all cases, robotic tumor enucleation achieved negative surgical margins in the vast majority of patients, even in case of complete PC invasion. At long-term follow-up, no recurrences were found at the enucleation site. Although our findings need to be confirmed by larger studies with longer follow-up, robotic tumor enucleation appears oncologically safe in experienced hands for the treatment of sporadic RCC.

Templates of Lymph Node Dissection for Renal Cell Carcinoma: A Systematic Review of the Literature.

Background: The role of lymph node dissection (LND) for renal cell carcinoma (RCC) is controversial. Notably, the conflicting evidence on the benefits and harms of LND is inherently linked to the lack of consensus on both anatomic templates and extent of lymphadenectomy. Herein, we provide a detailed overview of the most commonly dissected templates of LND for RCC, focusing on key anatomic landmarks and patterns of lymphatic drainage. Methods: A systematic review of the English-language literature was performed without time filters in July 2018 in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement recommendations. The primary endpoint was to summarize the most commonly dissected templates of LND according to the side of RCC. Results: Overall, 25 studies were selected for qualitative analysis. Of these, most were retrospective. The LND template was heterogeneous across studies. Indications and extent of LND were either not reported or not standardized in most series. The most commonly dissected template for right-sided tumors included hilar, paracaval, and precaval nodes, with few authors extending the dissection to the inter-aortocaval, retrocaval, common iliac or pre/paraaortic nodes. Similarly, the most commonly dissected template for left-sided tumors encompassed the renal hilar, preaortic and paraaortic nodes, with few authors reporting a systematic dissection of inter-aortocaval, retro-aortic, common iliac, or para-caval nodes. Conclusions: In light of the unpredictable renal lymphatic anatomy and the evidence from available prospective mapping studies, the extent of the most commonly dissected templates might be insufficient to catch the overall anatomic pattern of lymphatic drainage from RCC.

The Tumor Entity Denominated "clear cell-papillary renal cell carcinoma" According to the WHO 2016 new Classification, have the Clinical Characters of a Renal Cell Adenoma as does Harbor a Benign Outcome.

The new WHO 2016 classification of renal neoplasia encounters the new entity called "clear cell papillary renal cell carcinoma" (ccpRCC). The ccpRCC has been long included as a subtype of clear cell RCC histotype and it actually ranges from 2 to 9% in different routinely available cohort of renal carcinomas. Of important note, ccpRCC does not show any recurrences or metastases or lymph-node invasion and the outcome is always good. We reviewed twenty-four publications with available follow-up for patients (no. 362) affected by clear cell papillary RCCs/renal adenomatoid tumours and notably ccpRCC harbors an indolent clinical behavior after a mean of 38 months (3,5 years) of follow-up. This paper reviews the histological, molecular and clinical features characterizing ccpRCC, with the goal of focusing the knowledge of the benign fashion of this new tumour entity, supporting the idea of a new renal cell adenoma recruited morphologically from ex conventional clear cell RCC tumours.

The prevention of fragility fractures in patients with non-metastatic prostate cancer: a position statement by the international osteoporosis foundation.

Androgen deprivation therapy is commonly employed for the treatment of non-metastatic prostate cancer as primary or adjuvant treatment. The skeleton is greatly compromised in men with prostate cancer during androgen deprivation therapy because of the lack of androgens and estrogens, which are trophic factors for bone. Men receiving androgen deprivation therapy sustain variable degrees of bone loss with an increased risk of fragility fractures. Several bone antiresorptive agents have been tested in randomized controlled trials in these patients. Oral bisphosphonates, such as alendronate and risedronate, and intravenous bisphosphonates, such as pamidronate and zoledronic acid, have been shown to increase bone density and decrease the risk of fractures in men receiving androgen deprivation therapy. Denosumab, a fully monoclonal antibody that inhibits osteoclastic-mediated bone resorption, is also effective in increasing bone mineral density and reducing fracture rates in these patients. The assessment of fracture risk, T-score and/or the evaluation of prevalent fragility fractures are mandatory for the selection of patients who will benefit from antiresorptive therapy. In the future, new agents modulating bone turnover and skeletal muscle metabolism will be available for testing in these subjects.

Multiple and bilateral kidney tumors with clear cells of three different histotypes: A case report with clinicopathologic and molecular study.

We describe a rare multicentric neoplastic disease arising bilteraly in the kidney. The patient was a 70-year-old man, who, during a period of 3 years, was treated for five independent tumors of three histotypes (three multilocular cystic clear cell renal cell neoplasms of low malignant potential, one clear cell renal cell carcinoma, and one clear cell papillary renal cell carcinoma, respectively). Pathologic diagnosis of the reported tumors was confirmed by immunohistochemical analyses, including CD10, CA IX, CK7, AMACR/RACEMASE, and 34 beta E12. Molecular detection of KRAS, BRAF, NRAS, PIK3CA, ALK, ERBB2, DDR2, MAP2K1, RET, and EGFR gene mutational analysis was also performed in all tumors.

Comparing Image Perception of Bladder Tumors in Four Different Storz Professional Image Enhancement System Modalities Using the íSPIES App.

OBJECTIVES: To evaluate the variation of interpretation of the same bladder urothelium image in different Storz Professional Image Enhancement System (SPIES) modalities. SPIES contains a White light (WL), Spectra A (SA), Spectra B (SB), and Clara and Chroma combined (CC) modality. MATERIALS AND METHODS: An App for the iPAD retina was developed to study evaluation of images. A total of 80 images from 20 bladder areas acquired in four modalities were included. Seventy-three participants completed the study. Images were analyzed on differences in delineated tumor margin variation, perceived quality of the image, and delineation time. RESULTS: A separation between high agreement (n = 14) and low agreement (n = 6) images was found. In high agreement images, no difference in root mean square (RMS) was found between modalities. In low agreement images, WL (26.5 pixels) and SA (33.4 pixels) had a higher RMS than CC (18 pixels) and SB (21.4 pixels). The quality of SPIES modalities images was rated significantly higher. Delineation time was similar. CONCLUSION: In low agreement cases, images in CC and SB have less variation in interpretation than WL and SA. The image quality in SPIES modalities is graded significantly higher than WL. There is no difference in delineation time between modalities.

[Clinical practice and adherence to the diagnosis and treatment of NMIBC guidelines: a report of a recognition based clinical cases study]. / Pratica clinica e aderenza a Linee Guida nella diagnosi e terapia delle neoplasie vescicali non muscolo-invasive: report di uno studio ricognitivo basato su casi clinici.

For non-muscle invasive bladder cancer, a disease with a considerable epidemiological and socio-economic impact, the introduction of the Guidelines has always evoked as a tool for the resolution of long-standing disputes in terms of diagnosis and therapy. Check the degree of routine clinical practice adherence to the Recommendations is for this disease, more than for other uro-oncology pathology, an urgent need felt by the urological community. To assess the level of Guidelines adherence's, and study issues related to the paths of diagnosis and treatment of non-muscle invasive bladder cancer, and identifying the processes actually implemented in daily clinical practice, a series of case studies has submitted to a group of experts. The acknowledgement study allowed testing the impact of the current Evidence Based Medicine Recommendations in the everyday clinical practice identifying strengths and weaknesses. Questions Responses Analysis' of 5 clinical cases (Ta low grade, T1 low grade, T1 high grade, T1 high grade + CIS, Ta low-grade multiple recurrence) showed a moderate amendment to the European Association of Urology (EAU)-Guidelines. On the other hand, it was emphasized that there are clear discrepancies between what should be done, in accordance with the Evidence Based Medicine Recommendations, and what is actually do in everyday clinical practice. The most common reason for the low Recommendations adherences are structural and organizational practical limitations.

Technical solutions to improve the management of non-muscle-invasive transitional cell carcinoma: summary of a European Association of Urology Section for Uro-Technology (ESUT) and Section for Uro-Oncology (ESOU) expert meeting and current and future perspectives.

The aim of the present review was to compare state-of-the-art care and future perspectives for the detection and treatment of non-muscle-invasive transitional cell carcinoma (TCC) of the bladder. We provide a summary of the third expert meeting on 'Optimising the management of non-muscle-invasive bladder cancer, organized by the European Association of Urology Section for Uro-Technology (ESUT) in collaboration with the Section for Uro-Oncology (ESOU), including a systematic literature review. The article includes a detailed discussion on the current and future perspectives for TCC, including photodynamic diagnosis, optical coherence tomography, narrow band imaging, the Storz Professional Image Enhancement system, magnification and high definition techniques. We also provide a detailed discussion of future surgical treatment options, including en bloc resection and tumour enucleation. Intensive research has been conducted to improve tumour detection and there are promising future perspectives, that require proven clinical efficacy. En bloc resection of bladder tumours may be advantageous, but is currently considered to be experimental.

TriMatch comparison of the efficacy of FloSeal versus TachoSil versus no hemostatic agents for partial nephrectomy: results from a large multicenter dataset.

OBJECTIVES: To evaluate the efficacy of hemostatic agents, TachoSil and FloSeal, during partial nephrectomy using a large multicenter dataset. METHODS: Data of 1055 patients who underwent partial nephrectomy between January 2009 and December 2012 in 19 Italian centers were collected within an observational multicentric study (RECORd Project). The decision whether or not to use hemostatic agents after renorrhaphy and the type of hemostatic agents applied was adopted according to the centers' and surgeons' preference. A TriMatch propensity score analysis was applied to balance three study groups (no hemostatic agents, TachoSil, FloSeal) for sex, age, surgical indication (elective/relative vs imperative), clinical stage (cT1a vs cT1b), tumor exophyticity, approach (open vs minimally invasive), technique (standard partial nephrectomy vs simple enucleation), preoperative hemoglobin and creatinine. Postoperative complications and variation of hemoglobin and creatinine values between preoperative versus third postoperative day were compared. RESULTS: TriMatch analysis allowed us to obtain 66 well-balanced triplets. No differences were found in terms of outcomes between the study groups. CONCLUSIONS: The present findings suggest that adding hemostatic agents to renorraphy during partial nephrectomy does not provide better surgical outcomes.
