Executive Committee

Endourology encompasses the treatment of urinary tract stone disease, but it also includes the endourological treatment of other benign diseases of the upper urinary tract using minimally-invasive techniques.

The Section of Endourology was formed in 2002; it developed from the British Society for Endourology, which was a separate organisation, independent of BAUS. The Section aims to improve standards and quality of practice within the sub-specialty by promoting training, research and development. In 2009 the Section set up a Patient Advisory Group. The Section usually organises one scientific meeting each year and oversees a series of training courses. The Executive Committee is responsible for the organisation, financial administration and running of the Section.
