Lymphatic complications following renal transplantation.

Lymphatic complications following renal transplantation have not been previously described. Complications, resulting from the transection of lymph trunks during the preparation of the vascular pedicle, include Iymphocysts, abscesses, sinus tracts, and pelvic masses. The origin of the fluid in these spaces can be demonstrated by lymphography. Clinical signs of lymphatic complications include pain, swelling, a feeling of fullness in the area of the incision, and edema of the external genitalia and extremities. Late complications include obstructive uropathy, uremia, and fistula formation. Treatment involves aspiration and drainage; but, to prevent infection, puncture should be avoided if there is the possibility of spontaneous regression.
