The project dealt with the generic problem of training and monitoring minimally invasive endoscopic soft tissue surgery by tracking tools and tissue.

A training system for transurethral resection of the prostate (TURP) was developed as a particular concept demonstrator (hence the name TURP - Trainer/ Monitor). The final report can be downloaded.

The project was a joint venture of Imperial College and the Bristol Urological Institute at Southmead Hospital, carried out between April 1998 and March 2001. It was sponsored by the Engineering and Physical Sciences Research Council (EPSRC grant GR/L80577/01). Additional sponsors included Karl Storz Endoscopy (UK), and Limbs & Things Ltd.
