Summary & Timescale of the Data

General Information

The three data collection periods were:

  • 1 January 2017 to 31 December 2017;
  • 1 January 2018 to 31 December 2018 and
  • 1 January 2019 to 31 December 2019.

Surgeons who returned data for 2017 and/or 2018, but have stopped undertaking nephrectomies and did not return any 2019 data, are not displayed individually but their figures will still be included in the relevant unit data. 

It is also important to note that as a result of the COVID-19 crisis some surgeons and units may have been unable to submit all or any of their 2019 data.
