The study aims to investigate the rationale for LPN in patients with high-complexity renal tumors in terms of oncologic and functional outcomes.

From November 2009 to October 2018, 399 patients underwent LPN and 307 patients to laparoscopic radical nephrectomy (LRN). 41 patients with RENAL score ≥ 10 enrolled in LPN and 265 patients to the LRN group. Propensity score matching (matched by age, gender, clinical tumor stage, tumor size, baseline renal function, comorbidities such as diabetes mellitus (DM), hypertension (HT), coronary artery disease (CAD), and final tumor pathology of RCC) was used to reduce selection bias. Functional and oncological outcomes were compared between the two groups. After propensity score analysis, 39 patients in the LRN group were matched with 39 in the LPN group.

The aim of the study is to evaluate trifecta and pentafecta outcomes for laparoscopic partial nephrectomy (LNP) in patients with clinical T1N0M0 renal tumor.

From November 2009 to August 2018 a total of 292 patients who underwent LPN by global ischemia were included in the study. The patients were allocated into two groups according to the tumor size; T1a (≤ 40 mm, n=215), T1b (41-70 mm, n=77). Demographics features, clinical tumor characteristics, intraoperative and postoperative outcomes were analyzed. A negative surgical margin, warm ischemia time (WIT) \< 20 min and no postoperative complications (Clavien-Dindo ≥ grade 3) were accepted to achieve the trifecta outcomes. Pentafecta has defined as trifecta criteria plus \>90% preservation of estimated glomerular filtration rate (eGFR) and no stage upgrade of chronic kidney disease 12 months after LPN. Univariable and multivariable analysis were used to identify factors predicting trifecta and pentafecta achievement.
