Quality of Life in Living Kidney Donors Grenoble Teaching Hospital (France)

Context: Kidney transplantation is today the standard treatment for patients suffering from chronic end-stage renal failure. Living kidney donation offers many advantages for the recipient, but requires a subject without comorbidities to undergo surgery. The aim of this study was to assess the quality of life and psychosocial experience of living kidney donors after donation. Methods: This was a cross-sectional study with an analytical aim, involving living kidney donors during the period from January 2016 to April 2019 at CHUGA. (University Hospital Center of Grenoble Alpes in France). Results: Our study shows that out of 88 donors, 70 responded to our questionnaires, representing a prevalence of 80.5%. The average age of our donors was 55.6 years with a female predominance. Seven out of eight domains of the SF36 score had a good quality of life after donation and the donation did not alter their psychosocial experience. The majority of our donors expressed their pride and enthusiasm, did not regret having saved a life, and this experience was considered positive. Conclusion: Kidney donation does not have a negative impact on quality of life and psychosocial life. The majority of donors do not regret their donation. The dissemination of such results could make it possible to increase the number of kidney transplants from living donors in France, especially in our African countries where the management of ESRD remains a real public health problem.

Reasons and effects of the decline of willing related potential living kidney donors

BACKGROUND Although the availability of related living donors(LDs)provides a better chance for receiving kidney transplantation(KT),the evaluation protocols for LD selection remain a safeguard for the LD’s safety.These protocols are variable from one center to another,resulting in variable rates of decline of the potential LDs(PLDs).The decline of willing PLDs may occur at any stage of evaluation,starting from the initial contact and counseling to the day of operation.AIM To identify the causes of the decline of PLDs,the predictors of PLD candidacy,and the effect on achieving LDKT.METHODS A retrospective study was performed on the willing PLDs who attended our outpatient clinic for kidney donation to their related potential recipients between October 2015 and December 2022.The variables influencing their candidacy rate and the fate of their potential recipients were studied.Two groups of PLDs were compared:Candidate PLDs after a completed evaluation vs non-candidate PLDs with a complete or incomplete evaluation.A multivariate logistic regression was performed to assess the factors contributing to the achievement of PLD candidacy.RESULTS Of 321 willing PLDs,257 PLDs(80.1%)accessed the evaluation to variable extents for 212 potential recipients,with a mean age(range)of 40.5±10.4(18-65)years,including 169 females(65.8%).The remaining 64 PLDs(19.9%)did not access the evaluation.Only 58 PLDs(18.1%)succeeded in donating,but 199 PDLs(62.0%)were declined;exclusion occurred in 144 PLDs(56.0%)for immunological causes(37.5%),medical causes(54.9%),combined causes(9.7%),and financial causes(2.1%).Regression and release occurred in 55 PLDs(17.1%).The potential recipients with candidate PLDs were not significantly different from those with non-candidate PLDs,except in age(P=0.041),rates of completed evaluation,and exclusion of PLDs(P<0.001).There were no factors that independently influenced the rate of PLD candidacy.Most patients who failed to have KT after the decline of their PLDs remained on hemodialysis for 6 mo to 6 years.CONCLUSION The rate of decline of willing related PLDs was high due to medical or immunological contraindications,release,or regression of PLDs.It reduced the chances of high percentages of potential recipients in LDKT.

Hypertension and obesity in living kidney donors

Over the past few decades,the shortage in the kidney donor pool as compared to the increasing number of candidates on the kidney transplant waitlist led to loosening of kidney donors’acceptance criteria.Hypertension and obesity represent risk factors for chronic kidney disease,both in native kidneys and those in kidney transplant recipients.While great progress has been made in kidney transplantation from living donors to benefit the recipient survival and quality of life,progress has been slow to fully risk-characterize the donors.This review critically reassesses the current state of understanding regarding the risk of endstage kidney disease in those donors with obesity,hypertension or both.Accurate risk assessment tools need to be developed urgently to fully understand the risk glomerular filtration rate compensation failure in the remaining kidney of the donors.

Living kidney donor assessment:Kidney length vs differential function

BACKGROUND The key question in living kidney donor assessment is how best to determine the contribution of each kidney to overall renal function and guide selection of which kidney to donate,ensuring safety of procedure and good outcome for both recipient and donor.It is thought that a length difference>2 cm may indicate significant difference in function and therefore need for measurement of differential function.AIM To determine the effect of using kidney length to decide which kidney to donate in a retrospective cohort of potential donors.METHODS All 333 potential living kidney donors between January 2009 and August 2018 who completed assessment were retrospectively evaluated.Donor assessment was performed as per United Kingdom guidelines.Data included age,sex,kidney length(cranio-caudal)obtained by computed tomography/ultrasonography,51-chromium ethylenediamine tetraacetatic acid measured glomerular filtration rate,mercapto acetyl tri glycine split function and vascular anatomy.There were 48 exclusions due to inadequate data or incomplete investigations.Statistical analysis was performed using Excel pivot tables and GraphPad Prism.Correlation between kidney length and differential function was determined with Pearson’s correlation coefficient.RESULTS Of 285 potential donors included in the study,there were 144 males(mean age 49.9±14.75)and 141 females(mean age 51.2±11.23).Overall,the Pearson’s correlation between differences in length and divided function of kidney pairs was 0.1630,P=0.0058.Of 73 with significant difference(>10%)in divided function,18(24.7%)had no difference in kidney length;54(74%)had a difference of<2 cm and only one of>2 cm.Using a length difference of>1 cm would only predict significant difference in divided function in 8/34(23.5%)of cases.Using a difference of>2 cm as cut off for performing split function would lead to false reassurance in 72 patients(6 had>20%difference in divided function whereas 66 had 10%-20%difference).CONCLUSION Length difference between kidney pairs alone is not sufficient to replace measurement of divided function.This issue requires a randomised controlled trial to resolve it.

Acute kidney injury and the compensation of kidney function after nephrectomy in living donation

Acute kidney injury(AKI)incidence is growing rapidly,and AKI is one of the predictors of inpatient mortality.After nephrectomy,all the patients have decreased kidney function with AKI and recover from AKI.However,the characteristic and behavior of AKI is different from usual AKI and compensatory kidney function has been well known in the postoperative setting,especially in living donors.In this review,we have focused on the compensation of kidney function after nephrectomy in living donors.We discuss factors that have been identified as being associated with kidney recovery in donors including age,sex,body mass index,remnant kidney volume,estimated glomerular filtration rate,and various comorbidities.
