Abstract:
Objective To evaluate the applied value of multislice CT (MSCT) in the selection of living donor kidneys and excision methods.Methods Ninety living renal donors underwent MSCT assessment.The nonenhanced,arterial,venous and excretory phase examinations were performed.Using maximum intensity projection and volume rendering techniques for vascular imaging,two blinded radiologists independently analyzed and evaluated all MSCT images.According to the CT reconstructive images,radiologists and physicians selected the left renal or the right renal donors,and chose laparoscopic or open live donor nephrectomy.Results On the 90 cases of donors,78 donors underwent nephrectomy in the left kidney.Seventy-one left kidney donors having no significant variation received the routine laparoscopic live donor nephrectomy.Seven left kidney donors on both sides had relatively obvious anatomical variations such as accessory renal artery,multi-branch renal vein and renal vein in the back of the abdominal aorta,and they were subjected to the left kidney open donor nephre.ctomy.Other 12 donors having significant variation in the left kidney were given nephrectomy in the right kidney,and all of them received hand-assisted laparoscopic live donor nephrectomy.All intraoperative records of urine collection system and renal vascular anatomy were consistent with the preoperative evaluation of MSCT,and the accuracy was 100 ％.Two imaging experts in the evaluation of renal artery,renal vein and urine collection system showed good consistency.Nephrectomy was successfully performed on 90 cases of donors,and.postoperative recipients had no renal vein thrombosis and other vascular complications.Conclusion MSCT can provide accurate and valuable information for the selection of living donor kidneys and excision methods as a “one-stop” technique for the preoperative evaluation of living renal donors.
