Comparisons of surgical outcomes between transperitoneal and retroperitoneal approaches in robot-assisted laparoscopic partial nephrectomy for lateral renal tumors: a propensity score-matched comparative analysis

To compare the surgical outcomes between the transperitoneal (TP) and retroperitoneal (RP) approaches in robot-assisted laparoscopic partial nephrectomy (RAPN) for lateral tumors. This study included patients who underwent RAPN for lateral renal tumors between 2013 and 2019. Lateral tumors were defined as X of A factors in the RENAL nephrometry score. In total, 290 and 48 patients with TP and RP, respectively, were included in the analysis. To...
