Abstract

Purpose: Single-Port Robot-Assisted Partial Nephrectomy (SP-RAPN) can be performed by transperitoneal and retroperitoneal approaches. However, there is a lack of surgical outcomes for novel Retroperitoneal Low Anterior Access (LAA) in SP-RAPN. The study compared outcomes of the standard approach (SA), considering transperitoneal (TP) and posterior retroperitoneal (RP) access vs LAA in SP-RAPN series.

Methods: 102 consecutive patients underwent SP-RAPN between 2019 and 2023 at a tertiary referral robotic center were identified. Baseline characteristics, peri- and post-operative outcomes were collected. Patients were stratified according to surgical approach into standard (RP or TP) vs LAA and, subsequently, RP vs LAA. Multivariable logistic regression analysis was used to test the probability of the same-day discharge adjusting for comorbidity indexes.

Results: Overall, 102 consecutive patients were included in this study (68 SA - 26 TP and 42 posterior RP vs 34 LAA). Median age was 60 (IQR 51.5-66) years and median BMI was 31 (IQR 26.3-37.6). No baseline differences were observed. LAA exhibited significantly shorter length of stay (LOS) (median 10 [IQR 8-12] vs 24 [IQR 12-30.2.] hours, p < .0001), reduced post-operative pain (p < .0001) and decreased narcotic use on 0-1 PO Day (p < .001) compared to SA and RP only. Multivariate analysis, adjusting for comorbidities, identified LAA as a strong predictor for Same-Day Discharge.

Conclusion: LAA is an effective approach as well as RP and TP, regardless of the renal mass location, whether it is anterior or posterior, upper/mid or lower pole, yielding favorable outcomes in LOS, post-operative pain and decreased narcotics use compared to SA in SP-RAPN.
