NCT05743751

Brief Summary

Due to the rising incidence of renal failure and the improvement of organ transplantation technology, the shortage of donor organs has become one of the main problems limiting the development of kidney transplantation. Marginal donor is one of the important ways to extend the donor pool. Normothermic mechanical perfusion (NMP) is a new generation of organ preservation technology, which can maintain the blood supply and at the same time evaluate the marginal kidney function during the organ preservation. However, the clinical effect has not been proved. Hypothermic Machine Perfusion (HMP) is the mainstream organ perfusion technology. This study aims to compare the effectiveness of NMP with the HMP.

Study Arms (2)

Hypothermic machine perfusion

ACTIVE COMPARATOR

After organ acquisition, the donor kidney was trimmed, and then the donor kidney was connected to the cryoperfusion machine (lifeport, which has been used in routine clinical practice in our hospital) for continuous low temperature mechanical perfusion (\<8 ℃). The perfusion solution was extracted for proteomic study at 10 min after perfusion and at the end of perfusion.

Device: Hypothermic machine perfusion

Normothermic machine perfusion

EXPERIMENTAL

After conventional UW perfusion is obtained, the marginal donor kidney is immediately perfused without ischemia at normal temperature. The perfusion time is at least 4 hours (so as to repair the marginal donor kidney). The perfusion solution is as above, and the perfusion solution is loaded into the device authorized in Europe (XVIVO - KidneyAssist ®), Connect the transplanted renal artery with the device. Take 5ml perfusion solution in advance before perfusion, 5ml perfusion solution every 30min after perfusion, take perfusion solution at the end of perfusion (blood gas analysis for each perfusion solution, and finally perfusion solution for culture), and measure urine volume every hour. After perfusion, the transplanted kidney was disconnected from the perfusion device, and the donor kidney was perfused again with 2L HTK solution, followed by routine transplantation.

Device: Normothermic machine perfusion

Interventions

XVIVO (perfusion company, Gothenburg, Sweden), functions to be included in perfusion equipment, cardiopulmonary bypass machine and neonatal cardiopulmonary bypass machine, including polyethylene pipeline, heating equipment (perfusion temperature 37 ℃), venous pool (venous pressure is 0 mmHg, adjust the height of perfusion pool), centrifugal pump (arterial pressure is set at initial 75 mmHg, maintain 65 mmHg). The perfusion solution contains 215ml of dextran/albumin solution and 400ml of hematocrit, 2ml of 10% calcium gluconate, 1300u/L heparin and 400mg of cefazolin sodium. The oxygen/carbon dioxide ratio is (95%/5%, 2L/min) for continuous perfusion, and pO2 is maintained at 650mmHg during perfusion. During perfusion, continue to use verapamil, amino acid, glucose and insulin. Lactic acid Ringer solution (10ml/h) was used to supplement the lost circulation volume due to urine production during perfusion.

Normothermic machine perfusion

LifePort Kidney Transporter is designed to integrate with the clinical environment by using readily available supplies, requiring minimal user intervention, and by being easy to use. LifePort Kidney Transporter is a portable, isolated kidney perfusion and transport system, designed to support a donated kidney and to maintain the organ in a near-normal physiologic state under hypothermic aseptic conditions. An insulated plastic housing encloses the kidney and perfusate within a LifePort Kidney Transporter Disposable Perfusion Circuit. LifePort Kidney Transporter components include an Ice Container, Pump Deck, Control Panel, Outer Display, Bubble Detectors, External Connections Panel, sensors, and four lithium-ion batteries. Two handles make the unit easy to lift and carry
