How to monitor transplanted kidney by ultrasound?

Complications after renal transplantation are quite common. Ultrasonic monitoring is helpful to find complications such as ureteral obstruction, perirenal effusion and renal vascular disease, and to diagnose and distinguish renal rejection in time. In order to objectively monitor and compare the situation after renal transplantation, the same model or instrument should be selected for examination. The length, width, thickness and blood flow spectrum of the transplanted kidney should be measured respectively during the examination, and the echo of the kidney structure should be recorded by photography, and the dynamic observation should be compared before and after. The first ultrasound examination is usually performed within 24 hours immediately or as soon as possible after surgery, and then every three days. Generally, a high-frequency probe of 5 ~ 7.5 MHz is used to improve the resolution of the image. The bladder should be properly filled before examination.
