The Application of Internal Suspension Technique in Retroperitoneal Laparoscopic Partial Nephrectomy for Renal Ventral Tumors

Figure 2

Schematic diagram of the novel technique in RLPN for renal ventral tumors. (a) The perinephric fat along the surface of the kidney was carefully separated without resecting the perinephric fat atop the tumors. (b) The retained perinephric fat exerted traction on the tumor during tumor resection. (c) The closure of blood vessels and collecting system was performed with a unidirectional barbed suture. (d) The second layer suture was performed to close the parenchyma with the same suture.
