Experience sharing of percutaneous ultrasound guided renal biopsy
Objective To summarize the puncture skills in percutaneous ultrasound guided renal biopsy,so as to improve the success rate of biopsy sampling and reduce the incidence of complications.Methods A total of 74 patients requiring renal biopsy were selected,and percutaneous ultrasound guided real-time biopsy was performed after local anesthesia.The puncture skills during biopsy were summarized,and the success rate of biopsy,the incidence of complications and the results of pathological diagnosis were analyzed.Results 103 tissue strips were obtained in 74 patients,and the success rate of biopsy was 98.6%(73/74).Among the 74 patients,5 cases had a small amount of perirenal hematoma,of which 2 cases had a small amount of perirenal hematoma by ultrasonography 24 h later,and 3 cases had a small amount of perirenal hematoma due to lumbar discomfort during exercise1 week after surgery.The above conditions were absorbed and disappeared 2 weeks later without any other complications.The pathological results of 74 cases of renal biopsy showed that there were 11 cases of immunoglobulin A(IgA)nephropathy,19 cases of membranous nephropathy,4 cases of crescentic glomerulonephritis,7 cases of focal segmental sclerosing glomerulonephritis,5 cases of minimal change glomerulopathy,3 cases of interstitial glomerulonephritis,5 cases of lupus nephritis,6 cases of mesangial proliferative glomerulonephritis,2 cases of allergic purpura nephritis,9 cases of diabetes nephropathy,and 3 cases of amyloid nephropathy.Conclusion Percutaneous ultrasound guided renal biopsy is a method with high success rate and few complications.After mastering the theory of precision medical treatment,the cooperation between ultrasound department and nephrologists and patients is the key to successful puncture and reduce complications.
