There should be an attempt to salvage the transplant after allograft rupture in all cases. Using these transplant-preserving techniques, renal function could be achieved for all patients with allograft rupture.

The laparoscopic technique is an efficient, minimally invasive operation with optimal results. After a brief period of training the operation can be performed in 15-30 min and is therefore no longer than embolization techniques. Treatment of both sides in one session was not a problem.

Intercellular adhesion molecule-1 (ICAM-1) is the natural ligand of the T-lymphocyte adhesion molecule LFA-1 (lymphocyte-function-associated antigen-1). ICAM-1 is involved in target cell recognition by T-lymphocytes, LAK cells and natural killer cells. The molecule has also been detected on a variety of normal cells and on human tumors. Renal cell carcinoma (RCC) is one of the few tumors that respond to immunotherapy, but clinical results are generally disappointing. We therefore analyzed, by immunohistochemistry, the expression of ICAM-1 in pairs of normal kidneys, RCC, and RCC metastases. Moreover, serum ICAM-1 was determined in RCC patients and compared with surface expression of cell-bound ICAM-1. Strong glomerular expression of ICAM-1 was observed in all specimens of normal kidney examined. Proximal tubuli were weakly stained in the majority of specimens. Of the tumors, 80% stained positive for ICAM-1. Although ICAM-1 was detected on the majority of extrarenal tumor specimens examined, staining was generally weaker in the metastases. Patients without metastases at initial presentation more frequently expressed ICAM-1 in their primary tumors than did patients with metastases. Levels of serum ICAM-1 (sICAM-1) were significantly higher in RCC patients than in controls with non-malignant renal diseases. Patients with an unfavorable prognosis, e.g. with advanced tumor stage or metastasis at initial presentation, had higher levels of sICAM-1 than patients with low-grade and/or low-stage tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

We report an isolated echinococcal cyst of the kidney as a rare extrahepatic manifestation of the parasitic infestation. The pathogenesis, problems of diagnosis and treatment of renal hydatid disease are reviewed and discussed.
