Retroperitoneal Laparoendoscopic Single-Incision Radical Nephrectomy Without Special Platforms: A Single-Center Initial Experience

Abstract Objectives: To describe the initial experience of retroperitoneal laparoendoscopic single-incision radical nephrectomy (LESI-RN) without special platforms and use of conventional laparoscopic instruments and assess the safety and feasibility of LESI-RN. Subjects and Methods: Twenty patients who underwent LESI-RN were enrolled in this study. A 5-cm arc skin incision was performed at the midpoint between the costal arch and iliac crest on the midaxillary line. Trocars of 10, 5, and 11 mm were placed at the middle, left end, and right end of the arc incision, respectively. Demographic parameters and perioperative data were retrospectively analyzed and compared with the patients who underwent conventional retroperitoneal laparoscopic radical nephrectomy (LRN). Results: The LESI-RN patients had a significantly lower visual analogue scale (4.4 ± 1.9 versus 5.6 ± 1.4; P = .031) and analgesic requirement (18.5 ± 11.2 versus 28.6 ± 16.1; P = .026) compared with the conventional LRN group. The operation ti...
