- Abstract
Objective: To compare the surgical feasibility, oncological and functional results between sutureless and suture techniques in retroperitoneal laparoscopic nephron-sparing surgery (LNSS). Materials and Methods: This retrospective study collected consecutive patients with a renal mass who underwent retroperitoneal LNSS in two high-volume centers. Propensity score matching (PSM) analysis was conducted to select two baseline homogeneous cohorts. Descriptive statistics was performed both before and after PSM. Moreover, univariate and multivariate logistic analyses were carried out to identify the risk factors of postoperative acute kidney injury (AKI), whereas Kaplan-Meier analysis for functional deterioration (new-onset stage 3 chronic kidney disease [CKD], estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2, or CKD upstaging after surgery) was utilized to compare the two cohorts. Results: After PSM at a ratio of 1:3, the sutureless group (n = 65) was compared with the suture group (n = 152) with no remaining statistically significant differences in baseline characteristics. With regard to patient outcomes, differences in warm ischemia time (WIT) (P < .001), estimated blood loss (P < .001), AKI (P = .002), length of hospital stay (P = .020), and eGFR at discharge (P < .001) were statistically significant. Meanwhile, the postoperative complication rates (9.2% versus 13.8%, P = .378) and positive surgical margins (0% versus 2.0%, P = .556) were not statistically different. At the last follow-up, the eGFR decline percent was the same (-1.5% versus -2.2%, P = .192). No difference was detected on Kaplan-Meier analysis for functional deterioration (log-rank test, P = .304). Conclusions: Sutureless technique in LNSS is safe and feasible, compared with the traditional suture method, with shorter WIT, lower AKI rate, and comparable long-term oncological and functional outcomes.
