Laparoscopic living donor right nephrectomy: Assessment of outcome and association of BMI to length of right renal vein

Abstract

AimsThe 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 (RRV) from the donors. Material and methodsThis study was conducted in 60 donors from January 2016 to December 2017. We performed a retrospective review of consecutive patients who underwent transperitoneal right LLDN at our unit. ResultsLLDRN was successfully performed in all subjects by the same surgeons. There were 48 males and 12 females. Among 60 cases, 47 donors had single renal artery and vein, 2 cases had 1 artery and 2 veins, and 5 donors had 2 arteries and 1 vein, and the rest had 2–3 arteries with 1–3 veins. Operative time (OT) was 142.60±33.73min. Warm ischemic time (WIT) was 2.64±0.76min. The mean hospital stay was 6.69±0.63 days. The median length of RRV 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 WIT, that was higher BMI but shorter WIT in female versus male donors. Further analysis showed a negative correlation between BMI and RRV (r=−0.282, P<0.05), but a positive correlation between OT and estimate blood loss (EBL) (r=0.37, P<0.01). ConclusionsLLDRN 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.
