[First experience of 3D-laparoscopy in donor nephrectomy]

To assess the first experience of 3D imaging for laparoscopic donor nephrectomy.

The study included 28 laparoscopic donor nephrectomies and 28 subsequent transplantations to related recipients. Of these, 14 laparoscopic donor nephrectomies were performed using 3D camera. The main intraoperative parameters and information about postoperative period in donors and recipients were compared with similar data on previous laparoscopic donor nephrectomies and kidney transplantations with traditional 2D imaging. There were 15 left-sided and 13 right-sided nephrectomies. Twenty and eight laparoscopic nephrectomies were performed via retroperitoneal and transperitoneal access, respectively. There were no significant between-group differences in age, sex ratio, BMI, side of surgery and number of renal arteries.

Surgery time (119.28±9.18 and 124.85±7.49 min, respectively) and blood loss (106.78±16.12 and 119.28±19.79 ml, respectively) were similar. Laparoscopic nephrectomy with 3D imaging was followed by significantly shorter primary warm ischemia (2.41±0.79 and 3.23±0.57 min, respectively, p=0.004) and time of extracorporeal preparation of the transplant (back table) under cold preservation (27.21±5.42 and 32.36±5.33 min, respectively, p=0.02).

Initial experience of video systems with 3D imaging in laparoscopic donor nephrectomy has not yet led to significant reduction of surgery time and improvement of transplant function compared to traditional 2D imaging. At the same time, there was a shorter period of primary warm ischemia and back table time. Further analysis is needed to assess possible benefits of 3D imaging in laparoscopic donor nephrectomy.
