چكيده لاتين :
Lymphocele is a lymphatic collection around a transplanted kidney. Diagnosis is made when there is a pelvic collection with similar properties to the plasma. This can be confirmed with biochemical analysis of the fluid that shows similar electrolyte content compared with the plasma with low protein level. On microscopic evaluation, presence of lymphocytes can be a useful clue.(1) Lymphocele occurs 2 weeks to
6 months after transplantation with its peak incidence being at 6 weeks. On the other hand, its development following trauma to the kidney and delayed formation 8 years after transplantation has been reported, too.(2) The incidence of clinically significant lymphocele is about 20%, but it may develop in 12% to 40% of transplant recipients.(3,4) Since the
introduction of ultrasonography, in about half of transplanted kidneys,
collections smaller than 50 cm3 can be detected, most of which are less
than 3 cm in diameter and resolve spontaneously. Indeed, most of the lymphatic collections are subclinical.(3)
