Brief summary

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.

Detailed description

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

Design outcomes

Primary

Measure	Time frame	Description
Intraclass coefficient of correlation of the ultrasound volume measurement	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)

Secondary

Measure	Time frame	Description
Intraclass coefficient of correlation of the volume formula parameters.	6 months	The reproducibility of each formula parameter will also be assessed.
