Introduction: The presence of cancer in dogs was detected by Raman spectroscopy of urine samples and chemometric analysis of spectroscopic data. The procedure created a multimolecular spectral fingerprint with hundreds of features related directly to the chemical composition of the urine specimen. These were then used to detect the broad presence of cancer in dog urine as well as the specific presence of lymphoma, urothelial carcinoma, osteosarcoma, and mast cell tumor.

Methods: Multicenter retrospective analysis of patients from the REMARCC (REgistry of MetAstatic RCC) database. Patients were stratified by number of metastases into two groups, M1 (≤3, "Oligometastatic") and M2 (>3, "Polymetastatic").
We developed and tested a method to detect COVID-19 disease, using urine specimens. The technology is based on Raman spectroscopy and computational analysis. It does not detect SARS-CoV-2 virus or viral components, but rather a urine 'molecular fingerprint', representing systemic metabolic, inflammatory, and immunologic reactions to infection.

Methods: Multicenter retrospective analysis from the Registry of Metastatic RCC database.
Unlabelled: 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.

Patients who underwent RAUR or OUR for ureteral disease between 2016 and 2020 were identified. Data collected included baseline, pathologic, perioperative, and postoperative features.

Objective: To evaluate standard risk stratification features, develop an optimal model to identify ≥pT2/N+ stage at radical nephroureterectomy (RNU), and compare it with the existing unvalidated models.
Design, Setting, And Participants: This was a collaborative retrospective study that included 1214 patients who underwent ureterorenoscopy with biopsy followed by RNU for nonmetastatic UTUC between 2000 and 2017.
Background: The European Association of Urology risk stratification dichotomizes patients with upper tract urothelial carcinoma (UTUC) into two risk categories.
Objective: To evaluate the predictive value of a new classification to better risk stratify patients eligible for kidney-sparing surgery (KSS).
Design, Setting, And Participants: This was a retrospective study including 1214 patients from 21 centers who underwent ureterorenoscopy (URS) with biopsy followed by radical nephroureterectomy (RNU) for nonmetastatic UTUC between 2000 and 2017.
Background: Postoperative renal function impairment represents a main limitation for delivering adjuvant chemotherapy after radical nephroureterectomy (RNU).
Objective: To create a model predicting renal function decline after minimally invasive RNU.
Design, Setting, And Participants: A total of 490 patients with nonmetastatic UTUC who underwent minimally invasive RNU were identified from a collaborative database including 17 institutions worldwide (February 2006 to March 2020).
Background: Selection of patients for upfront cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) has to be improved.
Objective: To evaluate a new scoring system for the prediction of overall mortality (OM) in mRCC patients undergoing CN.
Design, Setting, And Participants: We identified a total of 519 patients with synchronous mRCC undergoing CN between 2005 and 2019 from a multi-institutional registry (Registry for Metastatic RCC [REMARCC]).
Background: Although breast cancer mortality is a result of distant recurrences associated with the establishment of tumor dormancy, current clinical practice guidelines recommend a wait and watch approach for tumor recurrences. This is because of our limited understanding of tumor dormancy and insufficient evidence in support of immunological control of tumor dormancy.
Methods: We used FVBN202 transgenic mice expressing rat neu oncogene in the mammary glands, and their parental FVB strain lacking neu expression.
Bladder cancer (BCA) is relatively common and potentially recurrent/progressive disease. It is also costly to detect, treat, and control. Definitive diagnosis is made by examination of urine sediment, imaging, direct visualization (cystoscopy), and invasive biopsy of suspect bladder lesions.

Methods: Within the Surveillance, Epidemiology and End Results Incidence Database, 6619 upper tract urothelial carcinoma cases were identified, including 3719 confined to the renal pelvis and 2971 to the ureter. Predictors of surgical technique (kidney sparing surgery versus radical nephroureterectomy), as well as 2- and 5-year cancer-specific survival and overall survival were evaluated.
Background: The use of organ sparing strategies to treat penile cancer (PC) is currently supported by evidence that has indicated the safety, efficacy and benefit of this surgery. However, radical penectomy still represents up to 15-20% of primary tumor treatments in PC patients. The aim of the study was to evaluate efficacy in terms of overall survival (OS) and disease-free survival (DFS) of radical penectomy in PC patients.

Objective: We aimed to evaluate morbidity associated with this procedure and identify potential predictors thereof to aid patient selection for this procedure and potentially improve patient outcomes.
Design, Setting, And Participants: Data from 736 mRCC patients undergoing CN at 14 institutions were retrospectively recorded in the Registry for Metastatic RCC (REMARCC).
Purpose: To perform a systematic review and meta-analysis of the literature inherent robotic nephroureterectomy (RNU) and to compare its outcomes with those of other nephroureterectomy (NU) techniques.
Methods: A systematic literature search was performed up to April 2019 using PubMed, Embase®, and Web of Science. The Preferred Reporting Items for Systematic Review and Meta-analysis Statement was followed for study selection.
Radical nephroureterectomy (RNU) represents the standard of care for high-risk upper tract urothelial carcinoma (UTUC). In selected patients with ureteral UTUC, a conservative approach such as segmental ureterectomy (SU) can be considered. However, this therapeutic option remains controversial.

Materials And Methods: This is a retrospective multicenter study (PEnile Cancer ADherence study, PECAD Study) on PC patients treated at 12 European and American centers between 2010 and 2016. Adherence to the EAU GL on the surgical management of the primary penile tumor and lymphadenectomy was evaluated.
The aim of the present study is to systematically review current evidence regarding the association between perioperative blood transfusions (PBT) and oncological outcomes of patients with renal cell carcinoma undergoing nephrectomy procedures. A computerized bibliographic search was conducted to identify pertinent studies. The Population, Intervention, Comparator, Outcome (PICO) study design approach was used to define study eligibility according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) criteria.

The cornerstone of many strategies includes patient education, liberalized oral intake on the day of surgery, no routine bowel prep, targeted multimodal analgesia, cautious use of IV hydration, early extubation, avoidance of NG tubes and/or surgical drains, and encouraging early postoperative ambulation. CASE REPORT We report on the successful outcome of a single patient with a rare autosomal dominant disorder (hereditary hemorrhagic telangiectasia) with multisystem involvement including pulmonary, cardiac, hematologic, gastrointestinal, renal, oncologic, and hepatic comorbidities, scheduled for open nephrectomy.
