Sonographic evaluation of renal allograft.

Sonography has become an integral part of the care of renal allograft recipients. It is a simple, inexpensive and readily available non-invasive imaging modality. It is indicated as the initial investigation in patients presenting with decreased urine output, pain, infection and hematuria and for doing a percutaneous allograft biopsy. While sonography confirms the diagnosis of obstructive nephropathy and perinephric fluid collections, Doppler is an effective screening modality for the detection of post-transplant vascular complications.
