The Challenge of External Generalisability: Insights from the Bicentric Validation of a [Ga]Ga-PSMA-11 PET Based Radiomics Signature for Primary Prostate Cancer Characterisation Using Histopathology as Reference.

: PSMA PET radiomics is a promising tool for primary prostate cancer (PCa) characterisation. However, small single-centre studies and lack of external validation hinder definitive conclusions on the potential of PSMA PET radiomics in the initial workup of PCa. We aimed to validate a radiomics signature in a larger internal cohort and in an external cohort from a separate centre.

Gold nanorod-assisted theranostic solution for nonvisible residual disease in bladder cancer.

Residual nonvisible bladder cancer after proper treatment caused by technological and therapeutic limitations is responsible for tumor relapse and progression. This study aimed to demonstrate the feasibility of a solution for simultaneous detection and treatment of bladder cancer lesions smaller than one millimeter. The α5β1 integrin was identified as a specific marker in 81% of human high-grade nonmuscle invasive bladder cancers and used as a target for the delivery of targeted gold nanorods (GNRs).

Double-face urethroplasty in patients with obliterative bulbar strictures post-transurethral resection of the prostate mid-term outcomes in high-volume referral center.

Objective: Incidences of post-transurethral resection of the prostate (post-TURP) strictures are between 2.2% and 9.8%.

Acute Kidney Disease in Oncology: A New Concept to Enhance the Understanding of the Impact of Kidney Injury in Patients with Cancer.

Background: Cancer patients are prone to developing acute kidney disease (AKD), yet this phenomenon remains understudied compared to acute kidney injury (AKI). AKD, which often develops insidiously, can cause treatment interruptions, extended hospital stays, and increased mortality.

Summary: This perspective article explores the intricate relationship between AKD and cancer, focusing on prevalence, risk factors, implications for anticancer therapy, and long-term outcomes, including chronic kidney disease progression.

Contemporary Diagnostic Work-Up for Male Infertility: Emphasizing Comprehensive Baseline Assessment.

Infertility is a prevalent issue affecting many couples during their reproductive years, with a significant number facing challenges in conceiving despite regular unprotected intercourse. Male factor infertility (MFI) contributes significantly to these cases, with a significant proportion of men lacking an identifiable etiology. As such, a thorough assessment of MFI has become increasingly vital for personalized management.

Defining the optimal target-to-background ratio to identify positive lymph nodes in prostate cancer patients undergoing robot-assisted [Tc]Tc-PSMA radioguided surgery: updated results and ad interim analyses of a prospective phase II study.

Introduction: Prostate-specific membrane antigen radioguided surgery (PSMA-RGS) might identify lymph node invasion (LNI) in prostate cancer (PCa) patients undergoing extended pelvic lymph node dissection (ePLND). The optimal target-to-background (TtB) ratio to define RGS positivity is still unknown.

Materials & Methods: Ad interim analyses which focused on 30 patients with available pathological information were conducted.

Measurement of Glomerular Filtration Rate in Patients Undergoing Renal Surgery for Cancer: Estimated Glomerular Filtration Rate versus Measured Glomerular Filtration Rate in the Era of Precision Medicine.

Background: In the era of precision medicine, determining reliable renal function assessment remains a critical and debatable issue, especially in nephrology and oncology.

Summary: This paper delves into the significance of accurately measured glomerular filtration rate (mGFR) in clinical practice, highlighting its essential role in guiding medical decisions and managing kidney health, particularly in the context of renal cancer (RC) patients undergoing nephrotoxic anti-cancer drugs. The limitations and advantages of traditional glomerular filtration rate (GFR) estimation methods, primarily using serum biomarkers like creatinine and cystatin C, are discussed, emphasizing their possible inadequacy in cancer patients.

The Association between Urinary Diversion Type and Other-Cause Mortality in Radical Cystectomy Patients.

Background: It is unknown whether more complex UD, such as orthotopic neobladder and abdominal pouch, may be associated with higher OCM rates than ileal conduit. We addressed this knowledge gap within the SEER database 2004-2020.

Methods: All T1-T4aNM radical cystectomy (RC) patients were identified.

Comparing outcomes of thulium fiber laser versus high-power Holmium:YAG laser lithotripsy in pediatric patients managed with RIRS for kidney stones. A multicenter retrospective study.

Background: The aim of this study was to evaluate thulium fiber laser (TFL) safety and efficacy compared to high-power (HP) Holmium:YAG laser in pediatric patients who have undergone retrograde intrarenal surgery (RIRS) for kidney stones.

Methods: We retrospectively reviewed data from pediatric patients who underwent RIRS for kidney stones between 2018 and 2020. Complications were assessed 4-6 weeks postoperatively.

Development and internal validation of a nomogram predicting 3-year chronic kidney disease upstaging following robot-assisted partial nephrectomy.

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.

Predictors of PSMA PET Positivity: Analysis in a Selected Cohort of Biochemical Recurrence Prostate Cancer Patients after Radical Prostatectomy.

Localized prostate cancer (PCa) can be treated with radical prostatectomy (RP). Up to 30% of patients undergoing this procedure experience biochemical recurrence (BCR), namely the rise in serum prostate-specific antigen (PSA) levels during the post-surgical follow-up, requiring further treatments and with the risk of severe disease progression. Currently, the most accurate imaging technique to confirm, detect, and locate disease relapses in BCR patients is prostate-specific membrane antigen (PSMA)-targeted PET, as recommended by international clinical guidelines.
