METHODS The study used data from the BAUS registry, a mandatory databse which records information on all PCNLs performed, for 2014 and 2015. Details were retrieved from the highest quartile volume surgeons and compared to the lowest quartiule volume surgeons. A series of comparisons of outcomes was then made between the high volume and the low volume groups. These outcomes included clearance on imaging at day one, blood transfusion, sepsis, complcations and post-operative length of stay. These comparisons were made for all stones accoridng to their Guys Stone Score (GSS) complexity, graded from 1-4. Comparisons were carried out using Fishers exact test. RESULTS 4035 PCNL were recorded. Those surgeons in the lower quartile performed 5 and 4 PCNLs or less in 2014 and 2015 respectively, and those in the upper quartile over 18 and 17 in the same time frames. Overall stone clearance, by imaging at day one, was higher in the higher volume surgeons for GSS1 (93% v 80%, p=0.01), GSS2 (74% v 63%, p=0.01), GSS3 (66% v 50%) and GSS 4 stones (37% v 35%, p=0.41), although not significantly for the latter. There was no difference in post op transfusion rates or sepsis. Conplication rates were higher for lower volume surgeons (9.6% v 4.7%, p=0.009). CONCLUSIONS Lower volume surgeons have higher complcations rates and lower stone free rates after PCNL. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e690 Advertisement Copyright & Permissions© 2017MetricsAuthor Information John Withington More articles by this author Sarah Fowler More articles by this author James Armitage More articles by this author Jonathan Glass More articles by this author William Finch More articles by this author Stuart Irving More articles by this author Neil Burgess More articles by this author Oliver Wiseman More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
