Abstract:
Objective:To explore the safety and feasibility of optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation(DKT)and evaluate its effectiveness to provide more alternative protocols for kidney transplantation from extended criteria donors.Methods:DKT was performed in 10 recipients using the same protocol from June 2019 to May 2021.And retrospective reviewing was performed for clinical data, including characteristics of donors and recipients, optimized pathological evaluation system, modified surgery, treatment regimens, complications and follow-ups.Results:There were 8 male and 2 female donors with an age of(57.9±12.8)years and BMI(24.1±4.1)kg/m 2.The percentage of DCD was 70% and DBD 30%.The serum creatinine before procurement was 107.6(93.3-163.5)μmol/l.Zero-point puncture biopsy was performed for both kidneys and optimized pathological evaluation system was implemented(Banff criteria & Remuzzi score). The pathological results indicated that glomerular sclerosis for left and right kidneys were 2.0(1.5-2.0)and 1.5(1.0-2.0). And Remuzzi score for left and right kidneys were(4.4±1.2)and(3.6±1.5)points respectively.All recipients were male with an age of(43.1±9.0)years and BMI(22.2±1.9)kg/m 2.All PRAs were negative pre-operation.Modified surgery was performed in all recipients(two kidneys were implanted outside iliac vessels without patch and artery of superior kidney was anastomosed to internal iliac artery). Operative duration was(195±54.3)min and serum creatinine before discharge 125.0(102.0-199.0)μmol/L.Renal dynamic scintigraphy indicated that glomerular filtration rate was(30.0±8.2)ml/min for left kidney and(29.2±13.9)ml/min for right kidney.MRA results indicated that morphologies of renal arteries and veins were regular.The time between operation and discharge was(22.4±4.7)days.Compared with SKT, serum creatinine before discharge of DKT was lower and DGF incidence of DKT was higher without statistical significance.The time between operation and discharge was longer for DKT than that for SKT( P<0.05). The complications consisted of 20% donor derived infection(DDI)and 50% DGF.And there was no surgical complication associated with vessels and ureter.Renal function remained stable during 6-month follow-ups. Conclusions:Optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation are both safe and feasible.The postoperative function of transplanted dual kidney is successfully restored.However, long-term follow-ups are required for evaluating its effectiveness.
