Retroperitoneal laparoscopic live donor nephrectomy offers an intrinsic advantage over conventional transperitoneal laparoscopic nephrectomy because of the potentially lower risk for early and late donor intraperitoneal complications.Herein we presented our experience performing retroperitoneal laparoscopic live donor nephrectomy in 105 donors.All donor nephrectomy was successful.There were no donor deaths and no conversion to open surgery.Mean operation time was 112 min(range,70-200 min).Intraoperative blood loss was 10-150 mL with an average of 30 mL.Warm ischemia time was 1.3 to 6 min with an average of 3.1 min.Postoperative retroperitoneal hematoma occurred in only one case and there were no other surgical complications.Donors were discharged from the hospital 5 to 10 days postoperation.Average postoperative hospital stay was 6.4 days.One graft was removed due to acute rejection.Delayed graft function occurred in two recipients but renal function returned to normal within four weeks.The other recipients had normal renal function in two weeks except three recipients in four weeks.We believe that retroperitoneal laparoscopic live donor nephrectomy is safe,reliable,and less invasive. 相似文献

Renal function of donors and recipients after living donor kidney transplantation in a Chinese cohort 总被引:2,自引:1,他引:1
Background Living donor kidney transplantation (LKT) has been booming in China. This study aimed to elucidate the renal function of both Chinese donors and recipients after the donation and transplantation.
Methods One hundred and forty-one pairs of donors and recipients for LKT were randomly selected and followed up for up to seven years. The donors’ and recipients’ renal function was recorded before and after operation.
Results The donors presented a mean age of (43.9±7.5) years at donation. The female contributed 101/141 (71.6%) in all donors, and no effect was shown between genders on healthy donors’ renal function. The donors’ glomerular filtration rates (GFR) were (119.5±20.4) ml/min, (85.2±17.6) ml/min, (87.2±15.9) ml/min, (82.1±14.6) ml/min and (83.0±13.7) ml/min preoperatively, and for five days, three months, one year and beyond one year after the operation. The donors for the period of 1–3 years, 3–5 years and more than 5 years after donation showed GFR as (83.9±12.7) ml/min, (83.0±17.6) ml/min, and (80.9±20.8) ml/min, respectively, no statistically significant difference was found. Moreover, no significant clinical changes in blood pressure and proteinuria were found among the donors. In the recipients, delayed graft function (DGF) rate was 6.4%, acute rejection rate was 11.3%, and GFR were (66.5±16.4) ml/min, (73.2±19.6) ml/min and (63.9±18.6) ml/min respectively at three months, one year and beyond one year post-transplantation respectively.
Conclusion The donors/recipients of LKT in Chinese population experience well-functioning remaining/donor kidneys.

Background The human leukocyte antigen-G (HLA-G) has been considered to be an important tolerogeneic molecule playing an essential role in maternal-fetal tolerance, upregulated in the context of transplantation, malignancy, and inflammation, and has been correlated with various clinical outcomes. The aim of this study was to investigate the clinical relevance of the expression of membrane HLA-G (mHLA-G), intracellular HLA-G (iHLA-G), and soluble HLA-G (sHLA-G) in the peripheral blood of live kidney transplant recipients.
Methods We compared the expression of the three HLA-G isoforms in three groups, healthy donors (n=20), recipients with acute rejection (n=19), and functioning transplants (n=30). Flow cytometry was used to detect the expression of mHLA-G and iHLA-G in the T lymphocytes of peripheral blood from subjects in the three groups. Enzyme-linked immunosorbent assays were used to detect sHLA-G in the plasma from the three groups.
Results There were no significant differences in mHLA-G and intracellular HLA-G among the three groups, but the sHLA-G plasma level was higher in the functioning group than in the acute rejection or healthy group. We found a subset of CD4+HLA-G+ and CD8+HLA-G+ T lymphocytes with low rates of mHLA-G expression in the peripheral blood of kidney transplantation recipients. Intracellular expression of HLA-G was detected in T lymphocytes. However, there was no correlation between acute rejection and the mHLA-G or intracellular HLA-G expression.
Conclusion sHLA-G was the major isoform in the peripheral blood of live kidney transplant recipients and high sHLA-G levels were associated with allograft acceptance.

Background Donor and recipient risk factors on graft function have been well characterized.The contribution of demographic factors,such as age,gender,and other potential factors of donor and recipient at the time of transplantation on the function of a graft is much less well understood.In this study,we analyzed the effects of factors such as age,gender,etc.,on the short-term and long-term graft function in kidney transplant recipients from living donor.Methods A total of 335 living donors and their recipients,who had kidney transplantation in our center from May 2004 to December 2009,were included.Serum creatinine level was used as the assessment criterion (serum creatinine level lower than 115 mmol/L is normal).Factors related to graft function such as age,gender,blood relation by consanguinity,human leukocyte antigen (HLA) mismatch,ABO type,etc.,were analyzed separately.Results Donor age is the key factor affecting both the short-term and long-term function of a grafted kidney from a living donor.The group with donors younger than 48 years showed the best kidney function post transplantation.Match of gender and age is another important factor that influences the function of grafted kidney from a living donor.The older donor to younger recipient group had the worst outcome after kidney transplantation.After 36 months post transplantation,female donor to male recipient group had worse kidney function compared to other groups.We also found that calcinerin inhibitor used in the maintenance period may influence the function of a grafted kidney.No significant statistical differences were found in consanguinity,blood type,and mismatch of HLA.Conclusions Donor age is an important factor affecting the function of a grafted kidney from a living donor.We also recommend taking nephron,immunology factor,infection,and demographic information all into consideration when assessing the outcome of kidney transplantation. 相似文献

Background Our goal was to evaluate the outcomes of kidney transplants from controlled cardiac death donors compared with brain death donors by conducting a meta-analysis of cohort studies.Methods The PubMed database and EMBASE were searched from January 1980 to July 2013 to identify studies that met pre-stated inclusion criteria.Reference lists of retrieved articles were also reviewed.Two authors independently extracted information on the designs of the studies,the characteristics of the study participants,and outcome assessments.Results Nine cohort studies involving 84 398 participants were included in this meta-analysis; 3 014 received kidneys from controlled cardiac death donors and 80 684 from brain death donors.Warm ischemia time was significantly longer for the controlled cardiac death donor group.The incidence of delayed graft function was 2.74 times (P 〈0.001) greater in the controlled cardiac death donor group.The results are in favor of the brain death donor group on short-term patient and graft survival while this difference became nonsignificant at mid-term and long term.Sensitivity analysis yielded similar results.No evidence of publication bias was observed.Conclusion This meta-analysis of retrospective cohort studies suggests that the outcome after controlled cardiac death donors is comparable with that obtained using kidneys from brain death donors. 相似文献
