BACKGROUND Ureteroscopy has traditionally been the preferred approach for treatment of distal and midureteral stones, with shock wave lithotripsy used for proximal ureteral stones. OBJECTIVE To describe the differences in the treatment and outcomes of ureteroscopic stones in different locations. DESIGN, SETTING, AND PARTICIPANTS Prospective data were(More)
Background:Prostate cancer (PCa) is characterised by great heterogeneity of the disease progression rate. Tumours range from insignificant and not life threatening to high risk for relapse ones. Consequently, a large number of patients undergo unnecessary treatment. miR-145 is a well-documented tumour suppressor and its expression, which is regulated by the(More)
BACKGROUND Recently accumulating evidences underline the central role of the kallikrein-related peptidases family (KLKs) in prostate cancer (PCa) development and progression. The KLK4 is a prostate highly expressed gene under the transcriptional control of androgens, encoding for the KLK4 extracellular serine protease. The aim of this study is to(More)
INTRODUCTION The extensive use of prostate-specific antigen as a general prostate cancer biomarker has introduced the hazards of overdiagnosis and overtreatment. Recent studies have revealed the immense biomarker capacity of microRNAs (miRNAs) in prostate cancer. The aim of this study was to analyze the expression pattern of miR-224, a cancer-related miRNA,(More)
Background:Accurate prediction of outcome for metastatic renal cell carcinoma (mRCC) patients receiving targeted therapy is essential. Most of the available models have been developed in patients treated with cytokines, while most of them are fairly complex, including at least five factors. We developed and externally validated a simple model for overall(More)
Accurate prognosis is a key factor in establishing optimal therapeutic decisions; yet in the case of bladder cancer (BlCa) current prognostic indicators cannot ensure optimal disease management. Here, we aimed to evaluate the previously unexplored clinical potential of the urological cancer-related miR-145, miR-143 and miR-224 in BlCa. A total of 279(More)
INTRODUCTION Self-inflicted foreign bodies in the male urethra and urinary bladder are an emergency that urologists may rarely have to face. A case of an electrical wire inserted in the male urethra and coiled in the bladder is presented. CASE PRESENTATION A 53-year-old male presented with the inability to void and bloody urethral discharge after having(More)
Relapsed urothelial cancer represents an unmet medical need. Vinflunine is a third-generation antimicrotubuline inhibitor and is currently the only approved drug for second-line treatment across the European Union. We conducted a retrospective analysis assessing the efficacy and safety of vinflunine in 71 Greek patients with relapsed urothelial cancer who(More)
The Notch signaling pathway controls cell fates through interactions between neighboring cells by positively or negatively affecting the processes of proliferation, differentiation and apoptosis in a context-dependent manner. This pathway has been implicated in human cancer as both an oncogene and a tumor suppressor. Here we report new inactivating(More)
Prostate biopsy is usually performed without anesthesia. We evaluated the patient’s perception of pain/discomfort experienced during the procedure in terms of the type of anesthesia used: periprostatic infiltration with 2% lidocaine, or intrarectal instillation of lidocaine-prilocain cream. A total of 198 patients were divided into three groups: group 1(More)
