The effect of enhanced recovery after surgery (ERAS) in renal surgery.

Objective: To study the effect of ERAS on a textbook outcome (TO) after elective renal surgery.

Patients And Methods: Retrospective study of all patients who underwent a robot-assisted laparoscopic partial or radical nephrectomy or robot-assisted laparoscopic radical nephroureterectomy in Medisch Spectrum Twente (MST), Enschede, the Netherlands. In total, 277 patients were included. 66 patients from 2018 to 2021 (pre-ERAS group) and 211 patients from 2021 to 2023 (ERAS group). TO is a maximum of two nights in the hospital after surgery, no severe complications during or after surgery ≥ grade IIIb, no blood transfusions, no intensive care, no readmissions, and no mortality within 30 days after surgery. Comparisons were made between the pre-ERAS and ERAS groups using unpaired t-test, Mann-Whitney U test, the chi-squared test or Fisher's exact test. Multivariate logistic regression was used to adjust for possible confounding.

Results: TO was significantly (p = 0.005) better in the ERAS group (TO = 76.8%) compared to the pre-ERAS group (TO = 59.1%). Compared to a pre-ERAS patient, the adjusted odds ratio for achieving a TO as an ERAS patient is 2.1 (95% CI 1.15-3.78).

Conclusions: The implementation of ERAS showed a positive effect on the TO of elective renal surgery patients.
