[The work of the Cochrane Collaboration in urology].

The Cochrane Collaboration collects medical information from clinical trials and presents the results as systematic reviews. The aim of these evidence-based publications is to enable medical decisions which are based on the best available evidence and to improve knowledge transfer in healthcare decisions. Accurately developed systematic reviews identify relevant clinical trials, evaluate their quality, abstract the results and are being published in an increasing frequency in professional urological journals. The Cochrane Library provides, with diverse databases, a quick overview of the best available evidence in urology. The quality of systematic reviews depends on the quality of the included studies. A checklist provided by the PRISMA statement could help authors and thereby readers to improve methodology and recommendations in evidence-based urology.
