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.
The 3 series of measurements 1. Longitudinal section: maximum longitudinal length, width at the hilum, maximum width, width at the upper third, longitudinal cross-sectional area 2. Transverse section at the hilum : thickness, width, hilar cross-sectional area 3. 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

Intraclass coefficient of correlation of the ultrasound volume measurement
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)
Time frame: 6 months
Intraclass coefficient of correlation of the volume formula parameters.
The reproducibility of each formula parameter will also be assessed.
Time frame: 6 months
