[The Onkonet database: taking stock of an Internet-based, multi-centre database on surgical prostate cancer treatment].

Background:  The Onkonet database has been developed and coordinated by the Berliner Tumorzentrum e. V. (http://www.

Hospital volume in ureterorenoscopic stone treatment: 99 operations per year could increase the chance of a better outcome-results of the German prospective multicentre BUSTER project.

Background: Despite the high utilisation of ureterorenoscopy (URS) in interventional stone treatment, there is little evidence of any link between annual hospital volume and outcome.

Methods: From January to April 2015, data from 307 URS patients were prospectively recorded in the multicentre observational BUSTER-Trial (Benchmarks of ureterorenoscopic stone treatment-results in terms of complications, quality of life, and stone-free rates). The best threshold value for annual hospital volume with an independent effect on the outcome (measured on stone-free and complication rates) of our study group was established with logistic regression.

Evaluating the use of prostate-specific antigen as an instrument for early detection of prostate cancer beyond urologists: results of a representative cross-sectional questionnaire study of general practitioners and internal specialists.

Objectives: The aim of this cross-sectional study was to evaluate the value of prostate-specific antigen (PSA) testing as a tool for early detection of prostate cancer (PCa) applied by general practitioners (GPs) and internal specialists (ISs) as well as to assess criteria leading to the application of PSA-based early PCa detection.

Methods: Between May and December 2012, a questionnaire containing 16 items was sent to 600 GPs and ISs in the federal state Brandenburg and in Berlin (Germany). The independent influence of several criteria on the decision of GPs and ISs to apply PSA-based early PCa detection was assessed by multivariate logistic regression analysis (MLRA).

Time trends in prostate cancer surgery: data from an Internet-based multicentre database.

Objectives: To report our experience with an Internet-based multicentre database that enables tumour documentation, as well as the collection of quality-related parameters and follow-up data, in surgically treated patients with prostate cancer. The system was used to assess the quality of prostate cancer surgery and to analyze possible time-dependent trends in the quality of care.

Patients And Methods: An Internet-based database system enabled a standardized collection of treatment data and clinical findings from the participating urological centres for the years 2005-2009.
