A comparison of recipient renal outcomes with laparoscopic versus open live donor nephrectomy.

TLDR: Although laparoNx allografts have slower initial function compared with openNx, there was no significant difference in longer term renal function.

Abstract: Background. Laparoscopic donor nephrectomy (laparoNx) has the potential to increase living kidney donation rates by reducing the pain and suffering of the donor. However, renal function outcomes of a large series of recipients of laparoNx have not been studied. Methods. We retrospectively reviewed the records of 132 recipients of laparoNx done at our center between 3/96 and 11/97 and compared them to 99 recipients of kidneys procured by the open technique (openNx) done between 10/93 and 3/96. Results. Significantly more patients in the laparoNx group (25.2%) were taking tacrolimus within the first month than those in the openNx group (2.1%). Mean serum creatinine was higher in laparoNx compared with openNx at 1 week (2.860.3 and 1.860.2 mg/dl, respectively; P50.005) and at 1 month (2.060.1 and 1.660.1 mg/dl, P50.05) after transplant. However, by 3 and 6 months, the mean serum creatinine was similar in the two groups (1.760.1 versus 1.560.05 mg/dl, and 1.760.1 versus 1.760.1, respectively). By 1 year posttransplant, the mean serum creatinine for laparoNx was actually less than that for openNx (1.460.1 and 1.760.1 mg/dl, P50.03). Although patients in the laparoNx compared to the openNx group were more likely to have delayed graft function (7.6 versus 2.0%) and ureteral complications (4.5 versus 1.0%), the rate of other complications, as well as hospital length of stay, patient and graft survival rates were similar in the two groups. Conclusion. Although laparoNx allografts have slower initial function compared with openNx, there was no significant difference in longer term renal function. Kidney transplantation is considered to be the treatment of choice for end-stage renal failure. Insufficient supply of organs for donation has produced long waiting times for many patients who may benefit from transplantation (1). During this period patients accumulate the morbidity of renal failure, they must endure the lifestyle limitations of dialysis, and they often die while waiting for the organ sharing system to grant them this resource. Live donor renal transplantation represents a large potential supply of organs that may relieve much of this shortage. Additionally, recipients of live renal transplants may reap benefits of improved patient and allograft survival that have been clearly demonstrated in this population (2,3). Although unilateral nephrectomy has proven to be safe and the solitary kidney state has been found to be well tolerated in a carefully chosen candidate for donation (4,5), substantial disincentives to donation exist. These include a significant hospitalization, prolonged convalescence period with time away from jobs, intractable perioperative pain, and, for some, cosmetic concerns of the resulting
