Complications associated with ureterorenoscopy (URS) related to treatment of urolithiasis: the Clinical Research Office of Endourological Society URS Global study

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. MethodsThe 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.ResultOn 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 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.ConclusionUreterorenoscopy 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.

Outcomes of ureteroscopy (URS) for stone disease in the paediatric population: results of over 100 URS procedures from a UK tertiary centre

“…With further digitisation of technology, reduction in scope size and improved laser fragmentation, it seems that the uptake of URS is going to increase for paediatric patients. Similarly, its role in complex patient groups or bilateral urolithiasis is likely to continue to evolve [35,36]. Recent evidence shows that outcomes for bilateral URS procedures are at least equivalent to staged procedures, minimising cost and hospital stay [36].…”

Unterschiede zwischen der stationären Komplikationsdichte nach einer Ureterorenoskopie und dem durch Patienten berichteten 30 Tages-Outcome – Ergebnisse der deutschen prospektiven BUSTER-Studie

“…Die im Rahmen dieser Arbeit erfasste Komplikationsdichte während des stationären Aufenthaltes liegt mit 7,7 % der Patienten genau in dem Bereich, der aufgrund der einschlägigen Literatur erwartet werden konnte. So wies die weltweit größte prospektive Studie zur Erhebung von postoperativen Komplikationen nach URS, die CROES URS Global Study, an nahezu 12 000 Patienten mit 7,4 % (dominant CD-Grade 1 oder 2) eine vergleichbar geringe Komplikationsrate und -schwere auf [7].…”

“…[CROES] URS Global Study) an nahezu 12 000 Patienten betrug die Gesamtkomplikationsrate 7,4 % [7]. Das ist zwar niedrig, insgesamt werden aber mehr Komplikationen nach URS im Vergleich zur extrakorporalen Stoßwellenlithotripsie (ESWL) berichtet [1].…”

Outcomes of ureteroscopy for stone disease in anomalous kidneys: a systematic review

“…The quality of included studies was poor with a high risk of bias and based mostly on small retrospective series; however, given the rarity of this condition, our review provides valuable insight, helps to condense the literature and might offer pitfalls and treatment strategies to endourologists. Although the reported complications in anomalous kidneys were higher, the rates of major complications were not different compared to URS in anatomically normal kidneys [30]. Future studies should also look at the cost comparison of the different treatment modalities [31][32][33].…”
