Urological malignancies, including prostate and bladder carcinoma, represent a major clinical problem due to the frequent occurrence of therapy resistance and the formation of incurable distant metastases. As a result, there is an urgent need for versatile and predictive disease models for the assessment of the individualized drug response in urological malignancies. Compound testing on ex vivo cultured patient-derived tumor tissues could represent a promising approach. In this study, we have optimized an ex vivo culture system of explanted human prostate and bladder tumors derived from clinical specimens and human cancer cell lines xenografted in mice...

Introduction: Three percent of all new diagnosed prostate cancer (PC) patients are under the age of 50. Multiparametric MRI (mpMRI) is considered as increasingly powerful tool for decision-making in diagnosis of PC and in some active surveillance protocols. Since prostate architecture changes with age, we evaluated the sensitivity of mpMRI to detect clinically significant PC in patients under the age of 50 compared to pair-matched older patients. Methods: Data from a prospective collected and ethics approved database were retrospectively analyzed...

BACKGROUND: Clinical registries provide physicians with a means for making data-driven decisions but few opportunities exist for patients to interact with registry data to help make decisions. OBJECTIVE: We sought to develop a web-based system that uses a prostate cancer (CaP) registry to provide newly diagnosed men with a platform to view predicted treatment decisions based on patients with similar characteristics. DESIGN, SETTING, AND PARTICIPANTS: The Michigan Urological Surgery Improvement Collaborative (MUSIC) is a quality improvement consortium of urology practices that maintains a prospective registry of men with CaP...

The optimal follow-up (FU) strategy for patients treated for localised renal cell carcinoma (RCC) remains unclear. Using the RECUR database, we studied imaging intensity utilised in contemporary FU to evaluate its association with outcome after detection of disease recurrence. Consecutive patients with nonmetastatic RCC (n=1612) treated with curative intent at 12 institutes across eight European countries between 2006 and 2011 were included. Recurrence occurred in 336 patients. Cross-sectional (computed tomography, magnetic resonance imaging) and conventional (chest X-ray, ultrasound) methods were used in 47% and 53%, respectively...

INTRODUCTION: Normal voiding needs a coordinated, sustained bladder contraction of adequate size and duration. It requires a decrease in resistance of the bladder neck and urethra and no obstruction. Voiding problems can arise from abnormal storage of urine or problems with urinary control. The aim of this article was to review the functional anatomy and physiology of urinary control and micturition and the pathophysiology of urinary control problems. MATERIALS AND METHODS: The Medline (PubMed) database, Cochrane Library, and Science Citation Index were searched electronically to identify original published studies on bladder anatomy, function and urinary control...

Penile squamous cell carcinoma is a rare cancer in men. The main prognosticators of survival for penile cancer patients remain the presence and the extent of lymph node metastasis. While radical inguinal lymphadenectomy has been the cornerstone of regional lymph node management for many years, it is still associated with significant morbidity and psychological distress. Recent developments in penile squamous cell carcinoma management have been met with some controversy in the urologic oncology community. Herein, we review the current controversies and developments on the role of inguinal lymphadenectomy for penile cancer...

INTRODUCTION: Robot-assisted surgery is practiced more and more frequently in urology. Besides its place in prostatectomy for cancer, it also concerns partial nephrectomy (NP), in the treatment of renal tumors. The objective of this review is to compare the robot-assisted approach with laparoscopic or open approaches in partial nephrectomy in terms of functional or oncological outcomes and per- and postoperative complications. MATERIAL AND METHODS: A systematic review of the literature published from 2009 was carried out on PubMed...

BACKGROUND: Urological symptoms such as gross hematuria, lower and upper urinary tract symptoms, and bladder pain are common in and distressing for patients with advanced cancer. Although palliation of urological symptoms is important to improve the quality of life of cancer patients and their families and caregivers, clinical guidelines for managing urological symptoms in patients with cancer have not been published. METHODS: Following the formal guideline development process, the Japanese Society for Palliative Medicine (JSPM) developed comprehensive clinical guidelines for the management of urological symptoms in patients with cancer...

Clinical trial data forms the foundation of how we treat men with metastatic prostate cancer who are initiating therapy. However, clinical trial data does not answer everything; hence, good clinical practice, pragmatism, and occasionally extrapolation drives how we manage these patients. Fortunately, multiple international guideline committees meet regularly and offer clinical guidance. In this mini-review, we focus on the United States National Comprehensive Cancer Network, European Society for Medical Oncology, and European Association of Urology (EAU) recommendations for the initial treatment of metastatic prostate cancer...

In urology technologies and surgical practices are constantly evolving and virtual reality (VR) simulation has become a significant supplement to existing urology methods in the training curricula of urologists. However, new developments in urology also require training and simulation for a wider application. In order to achieve this VR and simulation could play a central role. The purpose of this article is a review of the principal applications for VR and simulation in the field of urology education and to demonstrate the potential for the propagation of new progressive treatments...

Background: Prostate cancer (PCa) is a heterogeneous disease that lends itself toward numerous therapeutic options depending on its risk stratification. One of the greatest challenges in PCa urologic practice is to select patients who should be referred for biopsy and, for those patients who are diagnosed with cancer, to differentiate between patients with indolent disease from those with an unfavorable prognosis and, to determine ideal patient management and avoid unnecessary interventions. Accordingly, there is a growing body of literature reporting immunohistochemical studies with the objective of determining a prostate cancer prognosis...
