Nephrometry scores: a validation of three systems for peri‐operative outcomes in retroperitoneal robot‐assisted partial nephrectomy

Objective To externally validate the RENAL, PADUA and SPARE nephrometry scoring systems for use in retroperitoneal robot‐assisted partial nephrectomy (RAPN). Materials and Methods Nephrometry scores were calculated for 322 consecutive patients receiving retroperitoneal RAPN at a tertiary referral centre from 2017.
