Technical Modifications of Hand-Assisted Retroperitoneoscopic Living Donor Nephrectomy: A Single-Center Experience

Abstract

ObjectivesTo report a single-center experience and technical modifications of hand-assisted retroperitoneoscopic living donor nephrectomy (HARLDN). MethodsA total of 78 living donors underwent HARLDN from June 2004 to November 2009. We used a three-port, finger-dissecting, routine retroperitoneal approach. After almost complete mobilization of the kidney, the renal pedicle was dissected to expose the renal vessels. The ureter was dissected and divided at the level of the iliac vessels. An approximately 7-cm Gibson incision was made as the hand-assisted port. The surgeon's hand was introduced through this incision directly. With hand assistance, the renal artery was clipped using two Hem-o-lok clips at the proximal end, and then sheared by scissors without any clips on the kidney side. The renal vein was controlled similarly. Then the kidney was rapidly removed through the incision by hand. ResultsHARLDN was effectively and safely completed in 78 (100%) donors. No conversion to an open operation was necessary. The mean operative time and mean warm ischemic time were 121 minutes (range, 90–134) and 146 seconds (range, 112–247) respectively. The mean blood loss was 61 mL (range, 32–85). Clavien 1 complications including subcutaneous emphysema in 5.1% (4/78). The mean visual analog scales on postoperative days 1 to 5 were: 2.5, 1.2, 0.8, 0.5, and 0.1, respectively. The mean time to resume oral diet was 1.5 days. The mean hospital stay was 4.5 days (range, 4–5). The mean level of postoperative serum creatinines of the donors at 7 days and 1 month thereafter were 1.06 mg/dL (range, 0.74–1.43) and 1.15 mg/dL (range, 0.79–1.61) mg/dL, respectively. The mean level of postoperative serum creatinines of the recipients at 7 days and 1 month were 1.40 mg/dL (range 0.81–1.67) and 1.52 mg/dL (range, 0.76–1.83), respectively. The mean incision length was 6.5 cm (range, 6.0–7.2). ConclusionsThe modified HARLDN combines the purely laparoscopic technique with quicker, safer organ retrieval by the open access.
