Scoring systems correlated to complexity of partial nephrectomy – validated for warm ischaemia time and post-operative complications.

RENAL score:

4 – 6 : low complexity                                 (5 % complication rate)
7 – 9 : moderate complexity                      (10 % complication rate)
10 – 12 : high complexity                           (20 % complication rate)

 

PADUA classification – Preoperative aspects and dimensions used for an anatomical classification.

 

PADUA 6-7 best group ; 8-9 15 x risk of complications, 10+ 30 x risk.
