Living-related kidney transplantation: report of 175 cases / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical characteristics of living-related kidney transplantation (LRKT).</p><p><b>METHODS</b>From January, 2004 to December, 2008, 175 LRKT were performed including 63 cases (36%) of parent-child relations and 49 cases (28%) of sibling relations between the recipients and donors. Out of 175 donors, 52 were 50 years old or above, 4 had microscopic hematuria (including 2 with also hypertension), 2 had kidney stone, and 2 had high body mass index (BMI). Zero-point graft biopsy was performed in 59 donors, and abnormalities were found in 15 of them. The recipients were at the age of 33-/+10.5 years, and the primary diseases are mainly dominant glomerular nephritis (72.6%, 127/175), and with a few cases of diabetes (4%, 7/175) and hypertensive nephropathy (4%, 7/175).</p><p><b>RESULTS</b>Serum creatinine of the donors was 102-/+22.5 micromol/L at 7 days postoperatively, and 92-/+19.1 micromol/L at one month. One recipient died of severe pulmonary infection. Two recipients underwent graft nephrectomy due to anastomotic stenosis with concomitant acute graft rejection and renal arterial embolism. The one-year survival rates of the patients and grafts were 99.3% and 98.2%, respectively. The incident rates of accelerated rejection and acute rejection were 1.1% and 14.9%, respectively. Other complications included impaired liver function (22.3%), infection (9.7%) and leucopenia (4.6%). The renal arterial stenosis occurred in 2.3% (4/175) of the recipients.</p><p><b>CONCLUSIONS</b>The recipients of living-related and cadaveric kidney transplant have different primary kidney disease spectrums. Differential diagnosis and treatment of acute rejection and renal artery or anastomotic stenosis can be of vital importance. Marginal donor kidneys with appropriate inclusion criteria can be safely used for transplantation. With good short-term patient and graft survival, LRKT needs further study to evaluate its long-term effect.</p>
