Evaluation of single renal function in 117 donors following living renal transplantation during 5 years / 中国组织工程研究

ABSTRACT

OBJECTIVE: To generally, regularly, and continuously evaluate single renal function in donors following living renal transplantation, to study functional changes of single kidney, and to analyze clinical feasibility of living renal transplantation. METHODS: A total of 117 living kidney donors had been selected in this study. Following renal transplantation, indicators of creatinine (Cr), glomerular filtration rate (GFR), urine microscopic examination, blood pressure were monitored and followed up so as to generally evaluate the variation of single renal function and health status of living donor. RESULTS: All 117 living donors accepted kidney transplantation successfully. There were untoward events including 2 cases for drug anaphylaxis, 8 cases for microscopic hematuria, 5 cases for proteinuria, 15 cases for urinary tract infection, 3 cases for anxious emotion after operation, and 22 cases for wound pain. The blood pressure was increased in 19 cases and glomerular filtration rate (GFR) was decreased 4-25 mL/min with the average value of (9.4±4.7) mL/min in all cases, but the rates did not exceed the normal level. Nearly all of the cases displayed creatinine rising and 43 cases still had high creatinine level in 2 months after operation. There were no significant differences between creatinine level and sex, and left or right kidney of donor, but creatinine level of patients (> 50 years old) was significantly higher than patients (< 50 years old) (P < 0.01). Indicators of all cases returned the normal value after operation; however, creatinine level of 5 cases was still abnormal (135 μmol/L). CONCLUSION: The function detail could be fluctuated after living donor renal transplantation, or even exceeded the normal value, but the variation did not impact the whole function for the single kidney and influence the holistic health for donor, thus it could be safe and feasible for living donor renal transplantation.
