Hsu RC, et al. - The link between hospital case volumes and perioperative outcomes were investigated in radical nephrectomy, partial nephrectomy and nephrectomy with venous thrombectomy. Improved outcomes were reported by patients undergoing radical nephrectomy when treated by high-volume (HV) hospitals. There was no clear evidence of this in partial nephrectomy and nephrectomy with venous thrombectomy. It could be secondary to the low number of studies included and the small patient number. In order to establish the full potential of nephrectomy centralisation, advanced research was needed.
