Manual specimen retrieval without a pneumoperitoneum preserving device for laparoscopic live donor nephrectomy

Purpose: We present a novel method of kidney retrieval based on a modified Pfannenstiel incision and insertion of the assistant hand into the abdominal cavity without a device for pneumoperitoneum preservation. This maneuver is performed as the last step in pure laparoscopic live donor nephrectomy. Also, we assessed the effect of this technique on warm ischemia time compared with the standard laparoscopic bag retrieval technique. Materials and Methods: A total of 70 laparoscopic live donor nephrectomies were performed at our institutions between October 1998 and March 2001. The first 43 cases were completed using an EndoCatch bag device (Auto Suture, Norwalk, Connecticut) for specimen retrieval, while the last 27 were done using a novel manual retrieval technique through a modified Pfannenstiel incision. We retrospectively analyzed the results in regard to warm ischemia time and intraoperative complications related to the procedure. Results: A statistically significant difference was noted in the EndoCatch and manual retrieval groups in regard to warm ischemia time (p <0.001). There were 2 complications related to the EndoCatch device and none related to the manual technique. No differences were detected regarding recipient outcomes. Conclusions: Manual specimen retrieval after live donor nephrectomy allows shorter warm ischemia time, while saving the cost of an EndoCatch bag or pneumoperitoneum preserving device that would be used during hand assisted live donor nephrectomy. It was shown to be a safe method without increased donor morbidity.
