A laparoscopic donor nephrectomy is a surgical procedure performed to remove a kidney from a living donor for transplantation purposes. This minimally invasive technique involves making small incisions in the abdomen, allowing for the use of a laparoscope, which is a thin tube equipped with a camera and light. The procedure includes the cold preservation of the donor kidney, which is essential for maintaining the organ's viability until it can be transplanted into the recipient. During the operation, the surgeon creates a pneumoperitoneum by insufflating the abdomen with air, which provides a working space to visualize and access the internal organs. The lateral line of Toldt is identified and incised to mobilize the peritoneum over the kidney, allowing for better visualization of the kidney and its surrounding structures. The colon is carefully mobilized to gain access to the kidney, and various ligaments and fascia are divided to expose the renal hilum, where the renal artery and vein are located. The procedure requires meticulous dissection to avoid damaging the vascular pedicle and to ensure the kidney remains viable for transplantation. Once the kidney is fully mobilized and detached from its attachments, it is placed in a preservation bag, and cold preservation solutions may be applied to maintain its function until it is delivered to the recipient surgical team.
