简要总结
This study assesses the reproducibility of 3 different formulas in calculating the volume of a transplanted kidney by ultrasound in-vivo measurements.
3 series of measurements will be performed by 2 different operators during the usual ultrasound follow-up of the renal transplant.
详细描述
The 3 series of measurements
- Longitudinal section: maximum longitudinal length, width at the hilum, maximum width, width at the upper third, longitudinal cross-sectional area
- Transverse section at the hilum : thickness, width, hilar cross-sectional area
- Largest transverse section : thickness, width, maximum transverse cross-sectional area
Clinical and biological patient data collection:
age, gender, date of transplantation, serum creatinine and glomerular filtration rate (GFR), kidney transplant placement (right or left iliac fossa), acute illness or usual follow-up

结局指标
主要结局
Intraclass coefficient of correlation of the ultrasound volume measurement
时间窗: 6 months
The inter-observer and intra-observer variability of the ultrasound volume measurement of the kidney graft will be assessed using the intraclass coefficient of correlation (ICC)
次要结局
- Intraclass coefficient of correlation of the volume formula parameters.(6 months)
