Abstract  Introduction Ureterorenoscopy (URS) is a popular and growing option for management of ureteric and renal stones. The CROES URS Global Study was set up to assess the outcomes of URS in a large worldwide cohort of patients involving multiple centres. In this paper, we analysed the database for intra-operative and post-operative complications associated with ureterorenoscopy. Methods The CROES database was established via collaboration between 114 centres in 32 countries worldwide, and information on both intra-operative and post-operative complications was collected electronically between January 2010 and October 2012. Result  On analysis of a total of 11,885 patients, the overall complication and stone-free rates were found to be 7.4 and 85.6 %, respectively. The intra-operative and post-operative complication rates were 4.2 and 2.6 %, respectively, and in * J. de la Rosette [email protected] 1

total 5 deaths were reported in the study period. Taking into account different world economies, there were no differences in the complication rates between the developing and developed nations or between different centres from different continents. Conclusion  Ureterorenoscopy is a safe and effective procedure for treatment of stones, the outcomes of which are broadly comparable in different parts of the world for similar patient and stone demographics.

Introduction Ureterorenoscopy (URS) is used for management of urolithiasis and is often preferred due to its higher stone-free rate

(SFR) compared to shockwave lithotripsy (SWL), and lower complication rate compared to percutaneous nephrolithotomy (PNL) [1]. Most important complications of ureterorenoscopy are up-migration [1, 2] of stones, higher retreatment rates [1] due to incompletely removed stones (specifically in larger stones), and damage to the ureter [1–3] (from minor mucosal damage to avulsion) as a consequence of access sheath placement or difficulties with negotiating the ureter and rarely due to repetitive in and out movement of instruments. Most recent guidelines [4] state that the overall complication rate after URS is 9–25 %. Most complications are minor and do not require intervention, and ureteral avulsion and strictures are rare (15 mm: a single surgeon experience. Urol Int 96(1):77–82 2.
