With the advances in technology, more and more successful number of organ transplants has started.

Liver and kidney transplantation is the most common transplant operations.

The donor's kidney is often transplanted into the superficial area of the right lower quadrant, called the iliac region.

The anterior-vein of the kidney is anastomosed to the iliac vessels, the ureter (the tube collecting the urine leaking from the kidney) to the bladder (urinary bladder).

Although problems related to arteries and veins (obstructions, anastomosis stenosis) and urinary leakages are seen more frequently in the early period, problems related to ureter anastomosis occur more frequently in the late period.

In the treatment, re-surgery and interventional radiological treatments can be performed.

Interventional radiology is more prominent in post-transplant treatments because of a higher chance of recurrence of interventional therapies and less complication than surgery.
