Application value of biopsy through the upper pole of transplanted kidney under the guidance of ultrasound cardiac probe

Abstract

Objective: To investigate the value of needle biopsy of the upper pole of the transplanted kidney guided by the ultrasound cardiac probe. Methods: The success rates of biopsy at the upper pole of the transplanted kidney under the guidance of cardiac, abdominal and superficial probes were compared in 540 patients with impaired renal function after renal transplantation. The guidance was completed by an experienced sonographer and the puncture success rate was calculated. Pathologists make the diagnosis and count the success rate of diagnosis and the incidence of complications. Results: The success rates of puncture of the transplanted kidney under the guidance of the cardiac, abdomen and superficial probe were 100%, 85%,and 73%, respectively, the success rates of pathological diagnosis were 92.68%, 88.9%,and 80.7%, and the incidence of hematoma was 23.2%, 25.3%, respectively, 21.9%, and the pathological diagnosis was mainly acute and chronic rejection. Conclusion: The cardiac probe can clearly guide the puncture through the upper pole of the transplanted kidney, with high guidance success rate and good pathological tissue satisfaction and fewer complications. It is an effective guidance method after renal transplantation.
