Currently, there is no widespread use of percutaneous renal artery embolisation (PRAE) as a pre-operative treatment in the management of renal cell carcinoma (RCC). There is also a scarcity of studies concerning the potential benefits of this procedure. All patients with RCC who underwent pre-operative PRAE before nephrectomy (n = 227) and all patients(More)
Female gender is a risk factor for early mortality after coronary artery bypass graft surgery (CABG). Yet, the causes for this excess mortality in women have not been fully explained. To analyse gender differences in early mortality (30 days post surgery) after CABG and to identify variables explaining the association between female gender and excess(More)
About 30% of renal cell carcinomas (RCC) will develop recurrence after surgery. Despite evidence for a significantly improved survival by autologous tumour cell vaccination therapy, the procedure has not become standard. Between August 1993 and December 1996, 1,267 RCC patients undergoing radical nephrectomy in 84 German hospitals were subsequently treated(More)
OBJECTIVE To examine whether the predictive value of gender for health-related quality of life (HRQoL) is independent of clinical health status and depression. Women undergoing coronary bypass surgery generally report a poorer HRQoL than men. METHODS A total of 990 (20% women) patients completed study questionnaires 1 day before coronary bypass surgery(More)
OBJECTIVES To determine the value of microvascular invasion, tumor size, and Fuhrman grade to predict the survival of patients with surgically resected renal cell carcinoma (RCC). METHODS A total of 771 consecutive patients (T1-4, Nx, M0) were retrospectively reviewed. For each patient with RCC, the prognostic Sao Paulo score (SPS) was calculated using(More)
OBJECTIVE To determine the value of particular clinical variables for the preoperative prognostic Cindolo formula (PPCF) to predict disease-free survival (DFS) of patients with surgically treated renal cell carcinoma (RCC). PATIENTS AND METHODS In all, 771 consecutive patients (T1-4NxM0) who had radical or partial nephrectomy were reviewed(More)
OBJECTIVE The determination of further prognostic factors is essential for the establishment of risk groups for patients with surgically treated renal cell carcinoma (RCC). The objective of this study was to validate the prognostic value of macroscopic tumour necrosis, concerning postoperative survival. MATERIAL AND METHODS A total of 607 patients (387(More)
BACKGROUND Both the depression modules of the Hospital Anxiety and Depression Scale (HADS-D) and the Patient Health Questionnaire (PHQ-9) are widely used for the screening of depression. We analyzed the dimensionality and the item fit of both scales individually and across the scales. Moreover, we sought to identify items which evidenced item response bias(More)
PURPOSE Post-void residual urine can lead to various complications, including urinary tract infection. Recently investigators calculated that a cutoff value of 180 ml has considerably high sensitivity and specificity for significant bacteriuria in asymptomatic men. We determined the association between post-void residual urine volume and urinary tract(More)
BACKGROUND Awareness represents a major modulator for the uptake of preventive measures and healthy life-style choices. Women underestimate the role of cardiovascular diseases as causes of mortality, yet little information is available about their subjective risk awareness. METHODS The Berlin Female Risk Evaluation (BEFRI) study included a randomized(More)
