Society of Anesthesiologists score, Charlson comorbidity
index, Eastern Cooperative Oncology Group score, or the
more recently introduced frailty score
[45] .It was also not
possible to perform a pooled analysis of tumor complexity
scores, such as the RENAL or PADUA score, which have
facilitated standardization in reporting outcomes for
kidney surgery over the past 5 yr
[46] .Kopp et al reported
the only available series specifically looking at comparative
outcomes of PN and RN for clinical T2 renal masses after
adjusting for tumor complexity as based on the RENAL
score
[14,24]. While noting oncologic equivalence for PN
and RN irrespective of RENAL score, they nonetheless found
that patients with RENAL score
>
10 were at higher risk of
tumor progression
[14], and that RENAL score
>
10 was
associated with lack of renal functional benefit for PN
compared to RN.
