Modification and Validation of the System Causability Scale Using AI-Based Therapeutic Recommendations for Urological Cancer Patients: A Basis for the Development of a Prospective Comparative Study.

The integration of artificial intelligence, particularly Large Language Models (LLMs), has the potential to significantly enhance therapeutic decision-making in clinical oncology. Initial studies across various disciplines have demonstrated that LLM-based treatment recommendations can rival those of multidisciplinary tumor boards (MTBs); however, such data are currently lacking for urological cancers. This preparatory study establishes a robust methodological foundation for the forthcoming CONCORDIA trial, including the validation of the System Causability Scale (SCS) and its modified version (mSCS), as well as the selection of LLMs for urological cancer treatment recommendations based on recommendations from ChatGPT-4 and an MTB for 40 urological cancer scenarios.

Long-Term Orthopaedic and Radiological Outcomes of Symphysis Approximation without Osteotomy in Primary Bladder Exstrophy Repair.

Introduction:  Previous assumptions suggested that the technique of approximation without osteotomy in primary exstrophy repair (PER) could only be applied in newborns and anticipated poorer outcomes. Recent studies indicated that this technique can be successfully executed not only in immediate PER but also yields favorable long-term results. Therefore, we evaluated and compared the orthopaedic and radiological long-term outcomes after pubic symphysis approximation without osteotomy in immediate and delayed PER.

Patients Regret Their Choice of Therapy Significantly Less Frequently after Robot-Assisted Radical Prostatectomy as Opposed to Open Radical Prostatectomy: Patient-Reported Results of the Multicenter Cross-Sectional IMPROVE Study.

Patient’s regret (PatR) concerning the choice of therapy represents a crucial endpoint for treatment evaluation after radical prostatectomy (RP) for prostate cancer (PCA). This study aims to compare PatR following robot-assisted (RARP) and open surgical approach (ORP). A survey comprising perioperative-functional criteria was sent to 1000 patients in 20 German centers at a median of 15 months after RP.

Efficacy of Vinflunine for Patients with Metastatic Urothelial Cancer after Immune Checkpoint Inhibitor Pretreatment-A Retrospective Multicenter Analysis.

Background: Immune checkpoint inhibitors (ICI) are standard of care in patients with metastatic urothelial carcinoma (mUC) ineligible for cisplatin, and as second-line therapy after platinum-based chemotherapy. To date, few data exist about the efficacy of the former second-line chemotherapeutic agent vinflunine after the failure of sequential platinum-based chemotherapy and ICI treatment. The aim of this analysis was to examine the efficacy of vinflunine in a post-ICI third- or later-line setting.

Oncological Outcome and Value of Postoperative Magnetic Resonance Imaging after Focal High-Intensity Focused Ultrasound Therapy for Prostate Cancer.

Introduction: Focal therapy (FT) by high-intensity focused ultrasound (HIFU) is an emerging option for localized prostate cancer (PC). Due to the lack of long-term data, a close monitoring after FT is essential, but there are still uncertainties about the optimal follow-up regimen. Here we report on a series of FT-HIFU patients with the focus on oncological short-term outcome and the value of postoperative magnetic resonance imaging (MRI).

Perioperative antibiotic prophylaxis for stone therapy.

Purpose Of Review: To give an overview about state-of-the-art antibiotic prophylaxis in urolithasis therapy and focus on recent publications in this field.

Recent Findings: The number of high-quality publications within the recent time is limited. Preoperative inflammatory blood parameters like C-reactive protein and erythrocyte-sedimentation rate might help in prediction of postoperative systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL).

Prospective Evaluation of Predictive Parameters for Urinary Tract Infection in Patients with Acute Renal Colic.

Background: Acute renal colic (ARC) is an emergency that can mostly be treated conservatively, but can be life threatening in combination with urinary tract infection (UTI). Assessment for infection includes white blood cell (WBC) count and C-reactive protein (CRP), but these parameters are often unspecifically elevated and might lead to antibiotic over-therapy. In times of increasing antibiotic resistance, however, unnecessary antibiotic therapy should be avoided.
