[Kidney harvesting in living donors with manually assisted laparoscopy: technique and results]

To evaluate the feasibility and complications of manually assisted laparoscopic live donor kidney harvesting.

Since June 1999, all related live donor kidney harvests have been performed by manually assisted laparoscopy. The patient is placed in the lumbotomy position and an 8 cm midline periumbilical incision is made. The assistant's hand is introduced through a watertight port (HandPort). Three trocars are used. The assistant presents the structures to be dissected and controls the ureter. The artery is clipped and the vein is stapled or clipped, depending on its diameter. The kidney is extracted via the midline incision and washed.

Five kidney harvests were performed (three right kidneys and two left kidneys) with a mean operating time of 220 +/- 30 minutes. Conversion was necessary in one case following the intraoperative discovery of two right renal veins. Warm ischaemia lasted 5 minutes for the first patient and one to two minutes for the other four non-converted patients. Blood losses were minimal. The mean duration of major analgesia was 2.4 days and the mean length of hospital stay was 7.2 days. Complications were: bacteriuria in 2 cases and prolonged lymphorrhoea in 1 case. One transplanted kidney had to be removed because of immediate thrombosis of the recipient iliac artery. With a mean follow-up of 6 months (1 to 12 months), no ureteric or venous complications have been observed in the 4 evaluable transplanted kidneys.

An intra-abdominal hand during laparoscopic live donor kidney harvesting simplifies dissection, ensures intraoperative security and allows rapid extraction of the kidney.
