Abstract
AIMS
The aim of this study was to describe outcomes of laparoscopic living donor right nephrectomy (LLDRN) and study factors affecting the length of right renal vein from the donors.
MATERIAL AND METHODS
This study was conducted in 60 donors (48 males and 12 females) from January 2016 to December 2017. We performed a retrospective review of consecutive patients who underwent transperitoneal right laparoscopic living donor nephrectomy at our unit.
RESULTS
LLDRN was successfully performed in all subjects by the same surgeons. Among 60 cases, 47 donors had single renal artery and vein, 2 cases had one artery and 2 veins, and 5 donors had 2 arteries and one vein, and the rest had 2-3 arteries with 1-3 veins. Operative time was 142.60±33.73min. Warm ischemic time was 2.64±0.76min. The mean hospital stay was 6.69±0.63 days. The median length of right renal vein was 1.92±0.41cm. All transplanted kidneys showed immediate function. No graft losses were recorded. Almost no gender differences were found in study variables except BMI and warm ischemic time, that was higher BMI but shorter warm ischemic time in female versus male donors. Further analysis showed a negative correlation between BMI and right renal vein (r=-0.282, P<0.05), but a positive correlation between operative time and estimate blood loss (r=0.37, P<0.01).
CONCLUSIONS
LLDRN is a feasible safe procedure, less traumatic approach, and provides good outcomes kidney for recipients. Notably, in the study group the higher BMI was associated with resulting more difficult LLDRN and kidney transplantation.
