In an article by Vessey et al published in BJUI (2012) it was shown that surgeons with high case loads had better results than lower volume surgeons when doing radical prostatectomy. The study included a total of 8032 radical prostatectomy entered on the BAUS database and follow-up data was available on 4206 cases. Analysis of annual surgeon caseload revealed that 54% of surgeons performed an average of less than 10 procedures per annum and 6% of surgeons performed an average of 30 or more procedures per annum. When individual outcome variables where examined against surgeon case activity it was demonstrated that outcomes are clearly improved beyond 20 cases and there is a trend to continued improvement up to the series maximum of 40 cases per annum. There was an overall positive surgical margin rate of 38%.
