Given the limited evidence available, the original guidance committee noted that it would be beneficial to routinely collect data on all ureteric stent placement procedures. This was ideally in collaboration with a national professional society such as the British Association of Urological Surgeons. Clinical experts confirmed that an NHS registry for stent procedures has not been set up since the original guidance, and the evidence base remains limited with no prospective data available. The committee for this guidance update considered it important to further emphasise the need for collecting data using a national database or clinical registry on ureteric stent procedures. The prospective data collection should cover information about patient selection, choice of stent placement procedure and stent used, and adverse events such as
stent migration and encrustation rates. It concluded that this should form part of its recommendations in section 1 of the guidance, and agreed that such data collection should be used to help inform the most appropriate patient population for Memokath 051.
