Analysis of related factors of hematoma after ultrasound-guided percutaneous renal parenchy-mal biopsy
Objective To analyze the related factors of hematoma after ultrasound-guided per-cutaneous renal parenchymal biopsy.Methods A total of 100 nephropathy patients undergoing ultra-sound-guided percutaneous renal parenchymal biopsy in our hospital from February 2020 to February 2023 were retrospectively analyzed,and were divided into two groups according to the formation of postoperative hematoma,with 50 cases in each group.The incidence of postoperative hematoma in pa-tients with different pathological types and clinical diagnoses of renal biopsy were analyzed.The corre-lation factors of postoperative hematoma were analyzed by univariate and multivariate logistic regres-sion.Results Among the 100 patients,50 cases of postoperative hematoma.The main pathological type of renal biopsy was IgA nephropathy,with hematoma in 17 cases(56.67％).Followed by me-sangial proliferative glomerulonephritis,12 cases(60.00％)of postoperative hematoma;There were 6 cases(46.15％)of postoperative hematoma with IgM nephropathy.The main clinical diagnosis was glomerulonephritis,with postoperative hematoma in 28 cases(70.00％).Followed by nephrotic syn-drome,13 cases(37.14％)of postoperative hematoma.There were statistically significant differences in the proportion of patients with body mass index,proportion of patients with hypertension,proportion of patients with intraoperative coordination,proportion of patients with procoagulant drugs,time of on-set,depth of kidney from subcutaneous,length of puncture,number of puncture,prothrombin time,platelet,hemoglobin,blood albumin,blood creatinine and blood uric acid between the two groups(all P＜0.05).Multivariate logistic regression analysis showed that hypertension,time of onset,clinical stage,subcutaneous depth of kidney,et al.,were all influencing factors of postoperative hematoma(all P＜0.05).Conclusions The related factors of hematoma after ultrasound-guided percutaneous renal parenchymal biopsy provides an effective basis for clinical targeted intervention and preventive measures to reduce the risk of postoperative hematoma formation.
