Laparoscopic live donor nephrectomy: Current practice and results of renal transplantation

Objective: In 2009, 1659 patients with end‐stage renal failure in Hong Kong were waiting for a renal transplant. The overall number of renal transplants carried out locally remains low, with an even lower number being live donor donations. Yet, live donor kidney transplantation yields results that are consistently superior to those of deceased donor kidney transplantation, and laparoscopic donor nephrectomy (LDN) is increasingly accepted worldwide as a safe and preferred surgical option. We aim to evaluate the outcome of LDN in our setting, and to compare with that of deceased donors in this retrospective review. Patients and Methods: A total of 12 patients received LDN over the study period of 2006–2009. Standard left transperitoneal LDN was carried out. Grafts including three with double vessels were prepared using the bench technique. The postoperative outcomes up to 1 year for both the donors and the recipients were studied. Contemporary results for the 47 deceased donor kidneys were studied and compared. Results: All donors had an eventful recovery. The operating time was 225.0 ± 67.4 min. The hospital stay was 5.6 ± 2.3 days. The recipient outcomes including hospital stay and creatinine levels at discharge and 1 year were 11 days, 121 umol/L and 116 umol/L, respectively. Specifically, no ureteric stricture or graft loss was noted at the 1‐year follow up. Recipient complications included haematoma (1 patient), renal artery stenosis (1 patient) and redo of vascular anastomosis (1 patient). In contrast, the deceased donor graft recipients had a hospital stay of 11 days, and creatinine levels of 205 umol/L on discharge and 205 umol/L at 1 year, respectively. The delayed graft function rates for the live donor and deceased donors group were 0% and 14.9%, whereas the 1‐year graft survival rates were 100% and 87.2% respectively. Conclusion: The results showed that the donor morbidity rate was low, as reflected by the short hospital stay. Also, the overall parameters of recipients were good. In particular, no ureteric stricture was noted, and graft survival was 100% at 1 year. Living donor kidney transplant program using the laparoscopic technique is a viable option to improve the pool of kidneys for transplantation.
