Strategic hand assistance for effective and safe retroperitoneoscopic live donor nephrectomy.
Hand-assisted laparoscopic live donor nephrectomy has been widely applied, because it enables safe dissection of the renal vessels, reducing warm ischemia time (WIT) during rapid extraction of the kidney. In the method described in the current series, the hand-port device was placed after the kidney was mostly mobilized using a pure retroperitoneoscopic procedure. After placement of the hand port, the ureter was completely dissected by an open procedure. Finally, the renal vessels were dissected and transected under the hand-assisted retroperitoneoscopic procedure, and the kidney removed through the hand port. We performed 66 retroperitoneoscopic live donor nephrectomies, including 14 right-sided and 52 left-sided procedures, with this original method of hand assistance. The mean operative time, WIT, blood loss, and renal vein length were 246 +/- 43 minutes, 209 +/- 124 seconds, 202 +/- 180 mL, and 17.4 +/- 6.4 mm, respectively. Comparison of the operative data between the initial 30 cases and the recent 36 cases using the established method showed significant differences in blood loss and WIT that approached statistical significance. No delayed graft function was observed in the current series. The technical and functional outcomes were acceptable. The site and timing of hand assistance minimize the disadvantage of a small working space during the retroperitoneoscopic procedure, making surgery easier and safer.
