Abstract

Background: In this paper, the regular flow of ultrasound-guided renal allograft biopsies was established by analyzing complications and clinical management principle of ultrasound-guided renal allograft biopsies, to increase the safety of ultrasound-guided renal allograft biopsies.
Methods: The purpose of this study was to analyze the cases of ultrasound-guided renal allograft biopsies in our hospital from January 2006 to October 2018 because of abnormal renal function (including symptoms of albuminuria and elevated serum creatinine). The type of puncture needle used in renal allograft biopsies, the number of puncture needle and the relationship between puncture needle and complication were counted, and the treatment measures were analyzed.
Results: From January 2006 to October 2018, a total of 487 patients underwent ultrasound-guided renal allograft biopsies in our hospital. Among them, the successful sampling rate was 98.8%, and the average number of glomeruli per specimen was 15.24±2.26. The complications of the patient after puncture included: perirenal hematomas, subcapsular hematomas, acute ureter obstruction caused by hematuria, gross hematuria, and microscopic hematuria. Among them, two patients were treated with open surgery to save the function of renal transplantation, and the primary treatment measures were to increase the absolute bed rest time. The symptoms of the patients were relieved after treatment.
Conclusions: The analysis showed that ultrasound-guided renal allograft biopsies are safe and feasible, and the analysis of the biopsies of patients can provide meaningful pathological information for the clinic.
