ROLE OF COLOR AND POWER DOPPLER US IN DETECTION OF RENAL ALLOGRAFT COMPLICATIONS

Abstract

Kidney transplantation may be followed by a number of complications of parenchymal, urological, and vascular nature. Early diagnosis of these complications may determine the survival of the graft.

As graft recipients are fragile patients and may need decisive studies for fear of allograft failure, therefore, the diagnostic tool used to assess allograft dysfunction should be non-invasive as possible.

This study was aimed to evaluate the value of color duplex sonography and power Doppler in early diagnosis and follow-up of post-renal transplant complications.Our study was done on thirty patients ,they examined generally and locally.All patients were subjected to B-mode US, color and power Doppler and duplex Doppler US .They were classified into five groups.Group I included patients with no complications. Group II included patients with parenchymal renal complications, which were acute rejection, chronic rejection, and acute tubular necrosis. Group II included patients with dilated pelvi-calyceal system. Group IV included patients with perigraft fluid collection. The last group included patients with vascular complications, which were renal artery stenosis, renal vein thrombosis and arteriovenous fistula.
