Despite efforts aimed at preserving renal function, the functional decline after RAPN is not negligible. Based on the risk of intraparenchymal vessels injuries during renorrhaphy, with consequently loss of functional renal parenchyma, we aimed at comparing perioperative outcomes of patients undergoing sutureless RAPN (suRAPN) vs. standard RAPN (stRAPN). METHODS: Ninety-two consecutive patients treated with RAPN for clinically localized renal mass (cT1-2) from January 2019 and June 2020 by a single surgeon were included. Propensity-score matching was used to account for baseline differences between suRAPN and stRAPN patients. Specifically, the matched cohorts of suRAPN and stRAPN patients were balanced according to covariates, including age at surgery, preoperative eGFR, clinical tumor size, tumor complexity, defined according to PADUA score, and any individual PADUA item. Chi-square test, t-test and Kruskal-Wallis test examined differences on perioperative outcomes between suRAPN vs. stRAPN patients. RESULTS: Overall, twenty-nine (31%) patients were treated with suRAPN. After 1:1 propensity-score matching, no residual differences remained between the two groups. Only one suRAPN patient experienced intraoperative complications(p=0.9), namely venus bleeding during hilar dissection. Two (6.9%) suRAPN vs. four (13.8%) stRAPN patients experienced 30-day postoperative complications (p=0.3). Operative time (110 vs. 150 min; p<0.01), and length of stay(2 vs. 3 days; p=0.02) were shorter in suRAPN vs. stRAPN patients. TRIFECTA outcomes were achieved in twenty-five (86%) suRAPN vs. twenty (70%) stRAPN patients. Finally, only one (3.4%) suRAPN vs. five (17%) stRAPN patients experienced postoperative AKI. CONCLUSIONS: Sutureless technique in RAPN is a feasible and safe procedure, which demonstrates similar rates of intra- andpostoperative complications compared to the standard technique. Moreover, performing suRAPN may ensure lowerimpact surgery, as demonstrated by shorter operative time and length of stay. Despite promising results on TRIFECTAand functional outcomes are shown, prospective, randomized, trials relying on a larger cohort of patients with longerfollow-up are needed to further assess the impact of sutureless technique on long-term renal function.
