Design outcomes

Primary

MeasureTime frame
Tissue perfusion of the transplant recipient quantified by the defined HSI parameters (measured before reperfusion, t0 as well as 5 minutes after reperfusion, t1 and 10 minutes after reperfusion, t2) Oxygen saturation StO2 [%] Hemoglobin index THI [index 0-100] Near infrared perfusion index NIR [Index 0-100] Water index TWI [Index 0-100]

Secondary

MeasureTime frame
Urological complications (ureteral stenosis, urinary fistulas, vesicoureteral reflux), renal retention parameters (urea, creatinine and glomerular filtration rate), ureteral length after shortening
